Our Sheath-Core Polyester Low Melting Yarn utilizes advanced bi-component extrusion technology to revolutionize thermal textile bonding. Featuring a premium low-melt polyester sheath 110℃ surrounding a high-melt polyester core, the outer layer melts perfectly under steam or dry heat to create strong adhesive bonds, while the inner core remains fully intact. 

Key Value Propositions & Benefits
Advanced Sheath-Core (Bi-Component) Cross Section
Only the outer sheath melts at 110℃  to serve as the bonding agent. The structural core does not melt, acting as a permanent mechanical backbone that prevents fabrics from becoming brittle, stiff, or losing their structural shape after heat setting.

Precision Fine Denier Selection (30D / 50D / 70D)
Specifically tailored in ultra-fine deniers for high-end, lightweight, and high-gauge textiles. Perfect for seamless integration into delicate laces, translucent ribbons, and lightweight sportswear without adding bulk or rigid weight.

Zero Equipment Contamination & Cleaner Production
Because the core holds the molten polymer in place, this yarn prevents adhesive bleed-through or leakage. It entirely eliminates sticky residues on your factory's calendar rollers, steam ovens, and heat presses, cutting machinery maintenance downtime by half.

Superior Mechanical Tenacity & Easy Rewinding
The continuous polyester core delivers immense breaking strength. It handles high mechanical tension effortlessly, passing through computerized flat knitting, warp knitting, and automated winding equipment with near-zero breakage.

Uniform Polyester Compatibility
Being 100% polyester based, it ensures perfectly synchronized thermal shrinkage and flawless, streak-free dye affinity when mixed with standard polyester fibers.

Low Melting Yarn Industry knowledge

Sheath Core Low Melting Yarn 110 Degree is a bi-component polyester yarn built with a low melting polyester sheath wrapped around a regular polyester core. Once heated, the outer sheath softens and bonds surrounding fibers together, while the core keeps its strength and shape. At GC FIBER, this yarn is engineered for buyers who need a dependable bonding fiber that performs consistently across large production batches, whether the end use is nonwoven fabric, wadding, filter material, or composite reinforcement.

Product Overview

The sheath core structure is the defining feature of this yarn. Under a microscope, the cross section shows a clear ring of low melting polymer surrounding a solid polyester core. This design allows the yarn to act as both a structural fiber and a thermal bonding agent within the same strand, which reduces the need for separate adhesive materials in many downstream processes. We manufacture this yarn at our facility in Nantong with attention to consistent cross section geometry, since uneven sheath thickness is one of the main causes of uneven bonding results on the production floor.

Core Product Advantages

High Tenacity and Easy Rewind

The yarn holds up under tension during high speed winding and unwinding, which lowers breakage rates on the production line. Consistent package quality makes rewinding smoother and reduces downtime during changeovers.

110 Degree Melting Point

The low melting point activates bonding at moderate processing temperatures, which helps protect heat sensitive base fibers and can lower overall energy use during thermal bonding.

Reliable Bonding Agent

Acting as a built in adhesive fiber, it forms stable bonds between fiber layers without extra binder chemicals, which simplifies formulation and keeps the process cleaner.

Why Manufacturers Work With GC FIBER

Nantong Global Chemical Fiber Co Ltd, known as GC FIBER, has operated as a special textile factory in China since 2006. Our work is centered on researching, developing, producing, and selling special and functional eco friendly textile products, including Biodegradable Yarn, Low Melting Yarn, ECDP Yarn, Anti Static Yarn, HDPE Yarn, Bio component Yarn, and Polyester Filament Yarn. For sourcing teams evaluating a low melting yarn supplier, this focus means our production line is set up specifically around bi-component fiber structures rather than general purpose polyester, which supports steadier sheath core consistency batch after batch. We are also open to working with clients on new material development where a project calls for a modified melting point, tenacity range, or fiber specification.

Frequently Asked Questions

What does the sheath core structure actually do

The sheath, made from low melting polyester, melts first during heat treatment and bonds to neighboring fibers, while the core stays intact and keeps the yarn strong and stable after the bonding process is complete.

Is 110 degree suitable for heat sensitive base materials

Yes, a 110 degree melting point sits at the lower end of thermal bonding fiber options, which makes it a common choice when the surrounding material cannot tolerate high processing temperatures.

Can this yarn replace a separate adhesive coating

In many nonwoven and wadding applications, yes, since the sheath itself functions as the bonding agent, which can simplify the production process and reduce the number of materials involved.

Does GC FIBER support custom specifications

We work with clients on tenacity, melting point range, and fiber dimensions where a project needs an adjusted specification, and we welcome inquiries about new material development.
