Sheath-core polyester low melting yarn 110 degree is a specialized bi-component yarn designed to combine thermal bonding performance with the strength, stability, and processing reliability of polyester. Its unique construction places a low melting polyester sheath around a regular polyester core. When the yarn is exposed to controlled heat, the outer sheath softens and bonds neighboring fibers, while the inner core remains stable and continues to provide mechanical support.
This structure allows one yarn to perform two functions at the same time. The sheath acts as a built-in bonding agent, and the core functions as a durable reinforcement element. Compared with conventional low melting fibers, adhesive coatings, or single-component bonding yarns, sheath-core construction provides better control over bonding, improved dimensional stability, and greater flexibility in product design.
Available in 30D, 50D, and 70D counts, this yarn is suitable for lightweight and high-gauge textile applications. It can be used in three-dimensional knitted fabrics, chenille yarn, lingerie ribbons, lace, seamless underwear, ropes, cable wire sleeves, nonwoven structures, wadding, filtration media, automotive interiors, and other technical textile products.
Its approximately 110°C activation temperature makes the yarn suitable for processes that require thermal bonding at a moderate temperature. This can help protect heat-sensitive companion fibers, support efficient production, and simplify formulations by reducing the need for separate adhesive materials.
Sheath-Core Polyester Low Melting Yarn 110 Degree
Sheath-core polyester low melting yarn is a bi-component filament yarn manufactured through advanced composite extrusion technology. During production, two polyester components are introduced into a specialized spinning system. The low melting polyester forms the outer sheath, while regular polyester forms the central core.
The cross section resembles a solid central filament surrounded by a continuous polymer layer. The sheath is engineered to soften and flow at approximately 110°C, depending on the specific production specification and processing conditions. The core has a higher thermal resistance and remains substantially intact during normal bonding operations.
This arrangement is important because it prevents the entire yarn from losing its structure during heat treatment. In a conventional single-component low melting yarn, the whole fiber may soften or lose much of its mechanical strength. In contrast, a sheath-core yarn maintains a strong internal framework even after the outer layer has bonded to adjacent fibers.
The result is a yarn that can be incorporated into a fabric, web, narrow textile, or composite structure before being activated by heat. During the heating stage, the sheath creates adhesion at contact points. After cooling, the bonded structure retains the core-supported strength of the original yarn.
The sheath is the thermally active part of the yarn. It is formulated with a lower melting point than the core so that it softens first during heating. Once softened, it can attach to surrounding polyester fibers, other compatible textile materials, or nearby sections of the same structure.
Because the sheath is integrated directly into the yarn, the bonding material is distributed throughout the textile structure rather than applied only as a surface coating. This can provide more uniform bonding and reduce the need for separate adhesive films, powders, or liquid binders.
The sheath also supports cleaner processing. When temperature, pressure, and dwell time are correctly controlled, the polymer remains concentrated around the core and at the intended bonding locations. This may help reduce uncontrolled adhesive migration and minimize residue on production equipment.
The polyester core provides the yarn’s primary mechanical backbone. It contributes to tenacity, dimensional stability, handling performance, and resistance to breakage during winding, knitting, weaving, and other downstream operations.
After the sheath has softened and cooled, the core continues to support the bonded structure. This helps prevent the finished textile from becoming excessively brittle or losing its designed shape. The core is particularly valuable in lightweight products where a separate adhesive may create stiffness, unevenness, or an undesirable hand feel.
The core also improves process reliability. High-speed textile machinery places repeated tension on yarn packages, guides, needles, rollers, and winding systems. A strong core helps the yarn tolerate these mechanical demands and supports smooth unwinding with fewer interruptions.
The approximate 110°C melting point is one of the defining features of this product. The yarn is designed to activate at a moderate temperature, allowing manufacturers to create bonded textile structures without exposing the entire product to the higher temperatures associated with many conventional thermoplastic systems.
In a typical process, the yarn is first placed or blended with other fibers. The material may then pass through a heated chamber, steam system, hot-air oven, heated roller, press, mold, or another controlled thermal treatment unit. As the temperature reaches the activation range, the polyester sheath softens.
Pressure or close contact encourages the softened sheath to connect with adjacent fibers. When the material cools, the sheath solidifies and forms a stable bond. The exact result depends on temperature, dwell time, pressure, yarn ratio, fabric density, and the compatibility of the surrounding materials.
Processing conditions should always be confirmed through trials because the actual activation behavior can vary with machinery, line speed, fabric construction, and the thermal history of the complete product. The stated 110°C value should be treated as a reference point for development rather than as a universal setting for every application.
A moderate activation temperature can provide several practical benefits. It may help reduce thermal stress on heat-sensitive fibers, coatings, dyes, elastic components, and finished textile surfaces. It may also support shorter heating cycles or lower energy consumption when compared with higher-temperature bonding systems.
Moderate-temperature activation is especially useful in lightweight and delicate products. Lace, lingerie ribbon, seamless underwear components, narrow elastic structures, fine mesh, and three-dimensional knitted fabrics can be affected by excessive heat. A controlled 110°C bonding system gives manufacturers another option for creating structural connections while protecting the appearance and handle of the final product.
Lower-temperature bonding can also simplify equipment selection. Depending on the application, manufacturers may be able to use existing heat presses, steam equipment, ovens, or thermal rollers after suitable process validation. This can reduce the need for major capital investment when adding a bonding function to an established production line.
The most important advantage is the integration of bonding performance and structural reinforcement into a single yarn. A separate adhesive may bond fibers effectively but contribute little to the mechanical strength of the finished structure. A regular polyester yarn may provide strength but cannot normally create a thermal bond at moderate temperatures.
Sheath-core construction combines both functions. The sheath provides adhesion, while the core preserves strength. This can reduce material complexity and help manufacturers design lighter structures without sacrificing stability.
Because the core remains intact during thermal activation, the yarn can help maintain the shape of the bonded textile. This is valuable in products that must retain a particular thickness, outline, density, or three-dimensional form after heating.
The stable core may also reduce the risk of excessive shrinkage or collapse compared with a fully melting yarn. The finished result will depend on the complete material system, but the sheath-core design gives manufacturers a more stable foundation for process development.
Some adhesive systems can create hard or rigid areas, especially when applied unevenly or at excessive levels. A fine-denier sheath-core yarn distributes the bonding function through the textile structure while retaining a flexible polyester core.
This makes the yarn suitable for applications where softness, drape, elasticity, or comfort is important. In lingerie, lace, seamless underwear, and narrow ribbons, a properly selected yarn can create useful bonding without producing an unnecessarily harsh hand feel.
External adhesives can migrate, bleed through, accumulate on rollers, or require additional cleaning and ventilation controls. The integrated sheath keeps the bonding polymer within the yarn until activation, which can support cleaner handling and more predictable material placement.
This does not eliminate the need for proper temperature control or equipment maintenance. However, it may reduce problems associated with liquid adhesive application, excess coating, or uneven binder distribution. Manufacturers should evaluate equipment cleanliness during production trials and select operating conditions that prevent overheating.
The continuous polyester core provides high tenacity for a range of processing operations. The yarn can be wound into packages, unwound through guides, and introduced into knitting, weaving, braiding, or other machinery with good handling performance.
Easy rewinding is especially important when yarn is used in automated production. Poor package formation, uneven tension, or weak filaments can cause frequent stops and increase waste. Consistent winding and an adequately strong core help support stable production and reduce the risk of breakage.
The availability of 30D, 50D, and 70D options allows manufacturers to select a yarn according to the required balance of bonding contribution, weight, coverage, and mechanical performance.
Thirty-denier yarn can be considered for very lightweight and delicate constructions where minimum bulk is essential. Fifty-denier yarn provides an intermediate option for products requiring both fine appearance and dependable support. Seventy-denier yarn can be selected when a higher level of reinforcement or greater yarn presence is needed.
Actual performance depends on filament count, fabric construction, blending ratio, and processing conditions. Product developers should compare samples in the intended structure rather than selecting a count based only on denier.
Both the sheath and the core are polyester-based, which supports compatibility with standard polyester fibers and many polyester textile structures. This can simplify color development, material selection, and end-use testing.
When mixed with standard polyester, a polyester-based bonding yarn may provide more predictable behavior than a chemically unrelated adhesive fiber. It can also support a more uniform appearance and reduce the possibility of visible streaks or irregular dye behavior caused by incompatible materials.
Compatibility should still be confirmed for every specific dyeing, finishing, coating, and heat-setting process. Different polyester formulations can respond differently to temperature, pressure, solvents, and finishing chemicals.

The performance of sheath-core low melting yarn depends heavily on the accuracy of its bi-component structure. If the sheath is uneven, incomplete, or poorly centered, the yarn may bond inconsistently. If the core is damaged or improperly formed, tenacity and processing stability may be affected.
For this reason, the manufacturing process requires more than ordinary polyester spinning. It requires coordinated control of polymer preparation, melt temperature, extrusion balance, composite spinning, drawing, heat treatment, winding, and inspection.
The raw materials for the sheath and core are prepared according to their different melting and rheological characteristics. The low melting polyester sheath must flow consistently at the target processing temperature, while the core polymer must provide the required strength and thermal stability.
Material preparation includes control of polymer quality, drying conditions, moisture, filtration, and feeding accuracy. Polyester is sensitive to moisture during melt processing, so appropriate drying and handling are important for maintaining molecular stability and minimizing defects.
In the composite extrusion stage, the sheath and core polymers are conveyed through separate flow paths before being brought together in a specialized spinneret system. The equipment must maintain a stable ratio between the two components and keep the core correctly positioned inside the sheath.
Advanced bi-component extrusion technology makes it possible to control the cross-sectional geometry of the yarn. The objective is a continuous sheath surrounding the core with consistent thickness along the length of the filament.
Stable extrusion pressure, temperature management, filtration, and metering are essential. Small variations in these factors can influence filament diameter, sheath coverage, bonding performance, and mechanical properties.
The spinneret is one of the most important components in sheath-core production. Its design determines how the two polymer streams combine and how the final filament cross section is formed.
Maintaining a centered core and a uniform sheath helps ensure that the yarn performs consistently during heat activation. Manufacturers can use microscopic cross-sectional inspection and process monitoring to identify irregularities, incomplete coverage, eccentricity, or changes in sheath thickness.
Cross-section consistency is especially important for fine-denier products. In a 30D or 50D yarn, a small geometric variation can represent a meaningful change in the relative amount of sheath and core. Careful production control is therefore necessary to achieve repeatable bonding behavior.
After extrusion, the filaments are cooled and solidified under controlled conditions. The yarn is then drawn to develop the desired orientation and strength. Drawing conditions must be balanced carefully because excessive stress can damage the low melting sheath, while insufficient drawing may result in inadequate tenacity or unstable dimensions.
Heat treatment and relaxation may be used to stabilize the yarn and reduce unwanted tension. These stages contribute to package quality, rewinding performance, and downstream processing behavior.
After the filament has achieved the required properties, it is wound onto cones or other packages. Tension, traverse movement, package hardness, and winding speed must be controlled so that the yarn unwinds smoothly during customer use.
A well-formed package helps prevent snags, sloughing, uneven tension, and sudden yarn release. These factors are important in computerized knitting, warp knitting, narrow fabric production, and automated winding systems.
Quality control may include examination of yarn count, tenacity, elongation, melting behavior, package appearance, winding performance, and cross-sectional structure. Depending on the order, additional tests may be carried out for thermal shrinkage, bonding strength, moisture, color, and compatibility with a specific production process.
Sampling plans should be established for both incoming materials and finished yarn. Batch traceability supports faster investigation if a customer reports changes in bonding or processing behavior.
The supplier behind this product specializes in special and functional textile materials rather than treating low melting yarn as a minor extension of a general-purpose polyester line. This specialization supports a deeper understanding of bi-component fiber design, thermal bonding requirements, and customer-specific textile applications.
The company has operated as a special textile factory in China since 2006. Its product portfolio includes biodegradable yarn, low melting yarn, ECDP yarn, anti-static yarn, HDPE yarn, bio-component yarn, and polyester filament yarn. This broad but focused portfolio provides experience with functional fibers, specialty polymer systems, and application-driven material development.
A dedicated design and research and development function supports the development of special and eco-friendly textile products. This is important for buyers who require more than a standard catalog yarn.
Customer projects may involve a modified melting point, adjusted denier, different filament count, altered cross-sectional design, higher tenacity, or a special processing requirement. A supplier with internal development capability can evaluate these needs more efficiently and help convert them into a practical production specification.
Customization may cover denier, filament count, cross-section structure, melting point range, mechanical properties, package format, and other technical details. Special production by order allows customers to develop a yarn that matches their equipment and final product instead of adapting an existing material with unnecessary compromises.
Custom development normally begins with an application review. The supplier can assess the target fabric or composite structure, expected processing temperature, bonding method, required strength, and final hand feel. Laboratory or pilot samples may then be produced for customer testing before volume production.
Strong control over raw material supply and production planning helps support consistent quality and delivery. Multiple production lines and machines can also provide flexibility when customers require different counts, package formats, or order volumes.
Production flexibility is valuable for both smaller development orders and larger recurring programs. A buyer can begin with a controlled trial and scale the material after the performance has been verified.
Specialty yarn projects often involve multiple departments. Sales teams collect commercial and technical requirements, research and development teams review material feasibility, production teams prepare the process, and quality teams verify the finished product.
A coordinated professional team helps reduce communication gaps during this process. Customers can receive support from initial specification through sampling, testing, production, and delivery. Ongoing tracking and responsive service are particularly useful when a project has a strict launch schedule or requires several rounds of optimization.
Three-dimensional knitted fabrics require carefully controlled connections between layers, spacer structures, and support zones. Sheath-core low melting yarn can be incorporated into selected areas and then thermally activated to stabilize the three-dimensional form.
In footwear uppers, breathable mesh, cushioning structures, and technical spacer fabrics, the yarn may help reinforce zones that must resist deformation. The fine denier options allow designers to add support without unnecessarily increasing weight.
In chenille production, a bonding yarn can help secure fibers around the core and reduce the tendency of surface fibers to loosen. A sheath-core construction offers a combination of bonding and internal support that can improve the stability of the finished decorative or functional yarn.
Processing conditions must be selected carefully to prevent excessive stiffening or surface damage. The appropriate denier depends on the size, softness, and construction of the chenille product.
Lingerie ribbons and lace require a delicate balance between softness, appearance, strength, and edge stability. A low melting yarn can be used to create bonded points, stabilize narrow structures, or reduce fraying in selected areas.
The 30D and 50D options may be suitable for lightweight designs where a discreet bonding effect is required. Product trials should evaluate hand feel, flexibility, wash resistance, color, and skin-contact comfort.
Seamless underwear depends on smooth transitions, controlled elasticity, and minimal bulk. A fine sheath-core yarn can be integrated into selected zones to reinforce channels, edges, or structural areas without adding a thick separate adhesive layer.
The core provides support after bonding, while the sheath helps connect neighboring fibers. Correct yarn placement and thermal conditions are essential to maintain comfort and avoid hard spots.
In fine ropes, narrow bands, tapes, and technical cords, thermal bonding can help stabilize the arrangement of filaments and improve shape retention. The yarn can serve as a bonding component within a multi-yarn construction.
Seventy-denier yarn may be considered when a more visible reinforcement contribution is required, although the final choice depends on rope diameter, loading, flexibility, and production speed.
Heat-sealable cable wire sleeves can use low melting yarn to help secure textile coverings around cables or wires. The sheath bonds when heated, while the core helps maintain the sleeve’s tensile integrity.
Electrical and cable applications require careful evaluation of temperature resistance, flame behavior, insulation requirements, chemical exposure, and mechanical performance. The yarn should be tested within the complete sleeve system before approval.
In nonwoven fabrics, the yarn can function as a thermal bonding element within a fiber web. It can help connect fibers without adding a separate adhesive film or liquid binder. In wadding, quilts, pillows, and insulation materials, the bonded network may improve shape retention and reduce migration of loose fibers.
The quantity of low melting yarn, web density, heating method, and cooling conditions all influence the final structure. Manufacturers can adjust the formulation to balance softness, resilience, thickness, and bonding strength.
Filtration media often require stable shape, controlled porosity, and resistance to handling stress. A sheath-core yarn can help stabilize fiber layers or reinforce selected areas while maintaining a relatively fine structure.
The material should be evaluated for filtration efficiency, pressure drop, chemical resistance, temperature resistance, extractables, and long-term dimensional stability according to the intended filtration environment.
Automotive interior materials may include molded textiles, acoustic panels, backing layers, trunk liners, door components, and other composite structures. Thermal bonding yarn can support the connection between fibers or layers during molding and heat treatment.
Automotive applications typically require extensive testing for odor, emissions, abrasion, aging, temperature cycling, flame behavior, and dimensional stability. The low melting yarn can be considered as one component within a broader engineered material system.
Choosing between 30D, 50D, and 70D should be based on the complete product design rather than on yarn count alone. Important factors include fabric weight, desired bonding strength, softness, coverage, line speed, yarn placement, and the amount of structural support required.
Thirty-denier yarn is intended for very fine and lightweight constructions. It may be considered for delicate lace, translucent ribbon, fine mesh, lightweight lingerie, and applications where low bulk is essential.
Its smaller size may help preserve softness and visual refinement. However, a greater amount of yarn or a different construction may be required when the product needs stronger reinforcement.
Fifty-denier yarn offers a balanced option between fineness and support. It can be used in a wide range of narrow fabrics, knitted structures, lingerie components, light technical textiles, and general bonding applications.
This count is often a practical starting point for development because it provides a moderate bonding contribution without becoming as prominent as a heavier yarn.
Seventy-denier yarn may be selected for structures that require greater yarn presence, reinforcement, or bonding contribution. It can be suitable for selected technical textiles, ropes, cable coverings, thicker knitted structures, and composite applications.
The higher count may influence hand feel, flexibility, and fabric weight, so it should be tested carefully in lightweight or skin-contact products.
Before full-scale production, customers should conduct a controlled trial using the actual base fibers, fabric construction, equipment, and heating method. The purpose of the trial is to determine the relationship between temperature, dwell time, pressure, yarn content, and final bond quality.
Although the nominal melting point is approximately 110°C, the machine setting may need to be higher or lower depending on heat transfer efficiency and the structure being bonded. Surface temperature, internal material temperature, and actual exposure time may differ significantly.
Heating should be gradual and uniform where possible. Local overheating can cause excessive sheath flow, surface gloss, stiff areas, discoloration, or equipment contamination. Insufficient heating may produce weak or incomplete bonding.
Cooling is also important. The material should be allowed to stabilize after activation so that the bonded structure can develop its final shape. Excessive tension during cooling may distort the product or reduce the benefit of the bonding process.
For automated production, operators should monitor yarn tension, package unwinding, guide friction, line speed, and breakage rate. Stable yarn handling is often as important as the thermal performance of the sheath.
Using a built-in bonding fiber may help simplify material formulations by reducing the need for separate binders. Fewer material components can make storage, dosing, and production management easier. It may also reduce the number of coating or adhesive application steps.
Because the product is polyester-based, it can support compatibility with polyester recycling streams in applications where the complete product design and local recycling system permit it. Sustainability claims should be assessed across the entire textile, including dyes, finishes, companion fibers, coatings, and end-of-life conditions.
Energy efficiency is another potential benefit. A bonding system that activates at approximately 110°C may require less thermal energy than systems operating at significantly higher temperatures. Actual savings depend on equipment efficiency, heating time, production speed, product thickness, and factory conditions.
Cleaner processing can also improve factory efficiency. When the bonding polymer is integrated into the yarn, manufacturers may reduce the handling of liquid adhesives or powders. This can simplify housekeeping and help reduce contamination risks, although proper temperature management and routine equipment cleaning remain necessary.
Purchasing specialty yarn is not only a matter of comparing price per kilogram. Buyers also need to evaluate cross-section consistency, batch stability, package quality, technical support, customization capability, and delivery reliability.
A specialized manufacturer understands that different applications require different balances of melting behavior, tenacity, flexibility, shrinkage, and bonding performance. This knowledge can shorten product development time and reduce the risk of selecting a yarn that performs well in a laboratory but fails on a commercial line.
The supplier’s experience with special and functional textile products provides a foundation for application-focused cooperation. Instead of offering only a fixed specification, the company can work with customers to assess modified material requirements and develop new products when standard options are not sufficient.
Its location in Nantong, Jiangsu Province, provides access to China’s established textile manufacturing network and Shanghai seaport logistics. This supports domestic and international sourcing programs that require organized shipment planning and export coordination.
The sheath-core structure allows the outer low melting polyester layer to bond neighboring fibers when heated, while the inner regular polyester core remains stable and provides mechanical support. This combination gives the yarn both bonding and reinforcement functions.
No. The 110°C value refers primarily to the low melting sheath’s activation behavior. The polyester core is designed to retain its structure under the intended processing conditions. Actual results depend on the specific grade, heating method, and process settings.
In many nonwoven, wadding, narrow textile, and composite applications, it can reduce or replace the need for a separate adhesive component. A product trial is necessary to confirm whether the yarn provides sufficient bond strength and coverage for the intended design.
Thirty-denier and 50-denier options are commonly considered for lightweight lace, lingerie ribbons, and seamless underwear components. The final selection depends on the required strength, softness, transparency, bonding area, and fabric construction.
Seventy-denier yarn may be considered when the product requires a greater reinforcement contribution or stronger bonding presence. However, the complete structure and production process should be tested before making a final selection.
Yes. Because the product is polyester-based, it is generally suitable for development with standard polyester fibers and polyester textile structures. Compatibility should still be verified for the specific dyeing, finishing, heat-setting, and end-use requirements.
The moderate activation temperature can be useful for materials that cannot tolerate higher processing temperatures. However, every base material has its own thermal behavior, so testing is required to confirm that the complete product remains stable and retains its desired appearance and properties.
Yes. Custom development may cover denier, filament count, cross-sectional structure, melting point range, tenacity, package format, and other technical properties. Special production is arranged according to the customer’s requirements and order conditions.
Customers should test the yarn in the actual fabric or composite structure using the intended machinery. Evaluation should include yarn handling, breakage, thermal bonding, dimensional stability, softness, appearance, wash or aging performance, and any application-specific requirements.
The yarn can be rewound on cones or supplied according to the buyer’s packaging and equipment requirements. Package dimensions, net weight, winding density, labeling, and palletization should be confirmed during order preparation.
The product is manufactured by a specialty textile producer in Nantong, Jiangsu Province, China. The company has operated in the special textile field since 2006 and supplies functional yarn products for domestic and international customers.
It can be considered for automotive interior composites, filtration media, insulation, and other technical products. These applications require additional testing for temperature resistance, chemicals, odor, emissions, flame behavior, aging, and dimensional stability.
Sheath-core polyester low melting yarn 110 degree offers a practical solution for manufacturers seeking controlled thermal bonding, high tenacity, and lightweight structural support in one material. Its low melting polyester sheath activates at a moderate temperature, while its regular polyester core remains as a stable mechanical backbone.
The design provides important advantages over single-component low melting yarns and separate adhesive systems. It can support cleaner processing, improved dimensional stability, flexible product design, reliable rewinding, and compatibility with polyester-based textile structures.
With available counts of 30D, 50D, and 70D, the product can be adapted to delicate lace, lingerie, seamless underwear, ribbons, three-dimensional knitted fabrics, chenille yarn, ropes, cable sleeves, nonwovens, wadding, filtration products, and technical composites.
