Polyester Sewing Thread

Description

Polyester Sewing Thread is a 100% spun polyester thread built for dependable, everyday stitching across a wide range of fabrics and finished products. Available in counts from 20S to 80S in 2-, 3-, 4-, 6-, and 9-ply constructions, it delivers an average strength from 666 cN up to 3244 cN depending on size, with a controlled 8.5–16.5% elongation that keeps seams durable under repeated wear, stretching, and washing.

Its consistent tex and cotton-count grading make it easy to match thread weight to fabric weight, while Grade 4 washing color fastness keeps stitched colors sharp through repeated laundering. The result is smooth, low-lint sewing performance on both home and industrial machines, with stable stitch formation and reliable output across long, high-speed production runs.

This thread is widely used across suits, bedcovers, bedsheets, sportswear, sewing crafts and notions, as well as heavier-duty applications such as jeans, shoes, caps, leather goods, handbags, packing bags, tents, protective clothing, gloves, toys, and canvas products — making it one of the most versatile thread types across both apparel and home-textile manufacturing.

Key Selling Points

• High tenacity across all sizes: Average strength ranges from 666 cN (fine 60S/2) to 3244 cN (heavy 20S/3), covering light through extra-heavy sewing needs in one thread family. 
• Controlled elongation for durable seams: An 8.5–16.5% elongation range keeps stitches flexible enough to move with the fabric without losing shape or breaking. 
• Grade 4 wash color fastness: Tested against ECE detergent and steel-ball abrasion, the thread holds its color through repeated washing cycles. 
• 800+ color card with custom matching: A wide standing color range plus Pantone/shade-card matching supports branded and private-label production. 
• OEKO-TEX certified supply: Meets recognized safety and compliance standards for B2B sourcing into regulated retail markets. 
• Smooth, high-speed machine performance: Engineered to run cleanly through industrial machines with reduced lint and consistent tension. 
• Versatile sizing for multiple end uses: From 20S/9 packing-bag work to 80S/3 fine shirting, one product range spans apparel, home textiles, and heavy-duty goods.

High Tenacity 100% Polyester Sewing Thread

Polyester Sewing Thread is engineered for strength, consistency, and smooth sewing behavior across bulk production runs. Its spun polyester construction gives manufacturers a dependable balance of tensile strength and flexibility, holding up to daily handling, washing, and repeated stress without weakening the seam.

Available in a full range of counts and plies, it suits everything from lightweight garments to heavy-duty leather and packaging goods, with consistent quality across every cone and carton.
