Nylon High Stretch Sewing Thread for Spandex and Elastic Seams
Soft PA6 textured thread with high elongation and recovery for underwear, swimwear and performance apparel.
Product Overview
Nylon high stretch sewing thread is produced from textured PA6 nylon yarn through plying, heat setting, dyeing and controlled finishing. The soft, bulky structure provides high elongation, rapid recovery and comfortable seam coverage for garments that move closely with the body. Compared with lower-stretch polyester textured thread, nylon is selected where a seam must follow greater extension, especially in underwear, swimwear, leggings and performance apparel. Its abrasion resistance and smooth finish support repeated flexing and high-speed overlock or cover-seam production. Size, stretch, color, cone and packing are customizable after application testing.

FAQ
When should I choose nylon high-stretch thread?
Choose it when the seam must follow substantial fabric extension, especially in close-fitting spandex garments and high-movement areas.
How does it compare with polyester DTY?
Nylon high-stretch thread generally offers greater elongation and a softer, fuller hand; polyester DTY offers good moderate stretch and dimensional stability.
Can it be used in the needle?
Usage depends on thread size, machine and seam. It is often used in loopers; needle use must be validated through trials.
Is it suitable for swimwear?
Yes, for elastic seam construction, but resistance to chlorine, saltwater and finishing chemicals should be tested to the buyer’s standard.
Will the seam feel bulky?
The textured structure provides coverage without a hard edge. Thread size and tension should be selected for the desired seam profile.
Can you match fluorescent or fashion colors?
Custom colors can be reviewed from swatches or standards. Feasibility and fastness depend on the requested shade.
How should machines be adjusted?
Looper tension, needle, stitch density and feed should be optimized on the actual fabric to avoid seam tightness or looping.
Can packaging be customized?
Yes. Cone size, labels, inner wrapping and export cartons are available for OEM programs.
What details should I send for a quote?
