Key Product Features

· 100% high‑tenacity polyester filament raw material, high tensile strength, not easy to break during high‑speed industrial sewing

· Low shrinkage rate, stable stitch shape, avoid seam wrinkling after finished shoe washing & damp environment

· Outstanding abrasion resistance, fit long‑term friction of shoe upper, prevent seam cracking in footwear service cycle

· Smooth yarn surface, low lint, reduce needle breakage and thread jump fault for shoe‑making sewing machine

· Rich color selection, color fastness meets footwear standard, anti‑fading, resist color transfer to shoe upper materials

· Good heat‑resistance performance, adapt to high‑speed needle high‑temperature friction of industrial sewing equipment

· Large industrial cone design, reduce frequent cone replacement, improve continuous production efficiency of shoe factory

· Support custom color and yarn count according to customer sample, match diversified shoe‑material stitching demands

Application Fields

Special industrial sewing thread for shoe‑making factory stitching workshop

Footwear Industry: Stitching for sneakers, casual shoes, leather boots, safety shoes, sandals upper, shoe tongue, shoe collar, shoe lining

Leather Handicraft Industry: Sewing for leather bags, wallets, fabric luggage, canvas goods

Textile Processing: Heavy‑duty fabric, synthetic leather, micro‑fiber material industrial sewing processing

Sample‑making Workshop: Shoe prototype and pattern sample stitching work

Operation Guidance

Select matched thread specification according to material thickness; thick thread for heavy leather, thin thread for thin flyknit lining

Match proper industrial sewing machine needle size, avoid too‑small needle causing thread cutting and breakage

Keep thread cone placement stable during high‑speed sewing, prevent thread knotting and tangling

Avoid long‑time direct sunlight exposure for thread cones before using, prevent color fading

Check thread tension of sewing machine, adjust tension properly to guarantee neat stitching line

Social Responsibility & Environmental Protection

Adopt qualified polyester raw material, dyeing process follows low‑water‑consumption environmental dyeing standard, reduce dye wastewater pollution.

Export carton uses recycled corrugated cardboard printed with water‑based ink; single‑cone PE bag is recyclable plastic material.

Stable‑quality sewing thread reduces thread‑break defective rate on shoe production line, lower raw‑material waste for downstream shoe factories.

Support color batch traceability, complete material test report can be provided to satisfy overseas footwear environmental audit requirement.

Production workshop implements standardized labor protection management for dyeing and spinning operators, fulfill fair‑trade social responsibility.
