1. Nylon sewing thread (Nylon 6, Nylon 6.6)

Nylon sewing thread, also known as nylon sewing thread, pearl sewing thread, is made of continuous filament nylon fiber blended, smooth, soft, elongation of 20% — 35%, has good flexibility, burning white smoke . High abrasion resistance, good light resistance, mold resistance, coloring degree of about 100 degrees, low temperature dyeing. It is widely used because of its high seam strength, durability, flat seams, and the ability to meet a wide range of different sewing industrial products.

Here are its general physical characteristics:

2, special dragon sewing thread

Te Duo Long Sewing Thread: It is also called high-strength sewing thread and high-strength polyester sewing thread. It is made of continuous high-strength low-elongation polyester filaments. It has a temperature resistance of 130 degrees, high tensile strength, low elongation, and no elasticity. However, its wear resistance is poor. , harder than nylon thread, burning black smoke, 130 degree high temperature dyeing. Smooth, no more joints, good color fastness, meet the international environmental protection requirements of the sewing thread.

Its common specifications and models are:

3, PP pure polyester sewing thread

PP pure polyester sewing thread line, also called SP sewing thread line, PP sewing thread line, is also made of high strength and low elongation polyester raw material, the surface has wool, temperature 130 degrees, high temperature dyeing. Polyester material is the most resistant to friction, dry cleaning, stone washing, bleaching and other detergents in all materials. Its low elongation and low expansion rate guarantees excellent seamability and prevents wrinkles and hops. needle.

Common models are:

20S/2, 20S/3, 20S/4, 30S/3, 30S/2, 40S/2, 40S/3, 50S/2, 50S/3, 60S/2, 60S/3

4, Bondi sewing thread

The Bondi line consists of two materials, Nylon 6 and Nylon 6.6, which are blended with continuous nylon filaments and bonded together to bind all yarns together. Even if they are cut with scissors, they are never Will leave open. And then through the high-performance lubrication process, it can meet the daily heavy-duty sewing process, such as: leather, canvas products or sports shoes.

Elongation rate of 20-28%, better wear resistance, not easy to break, the surface as smooth as a ribbon.

Common models:
