Sewing thread is the thread required for knitted clothing products. Sewing threads can be divided into five types according to different raw materials: cotton sewing thread, pure cotton thread, polyester sewing thread, polyester-cotton sewing thread, and nylon sewing thread. The sewing thread is made of pure polyester fiber. Its raw materials are more. The production of polyester sewing thread needs to go through six processes, such as cleaning, winding, carding, slivering, roving, spun yarn, stitching, and twisting.
Types of sewing thread
1. Cotton sewing thread
Good heat resistance, poor elasticity, abrasion resistance, moisture resistance, and anti-bacterial ability, suitable for high-speed sewing and durable pressing. The most used is long-staple pure cotton thread, which is made of long-staple cotton through combing, singeing, mercerizing, and high-density twisting, so the tensile force is better than ordinary combed cotton. It is often used for sewing pure cotton clothing and other pure cotton fabrics.
2. Pure cotton thread
The pure cotton thread is generally divided into two parts: carded and combed. The real 100% pure cotton thread can be used for sewing as fully combed cotton. Generally use 402, 202, 203 more. It is made by combing and singeing high-quality cotton in cotton area. Pure cotton thread is often used for sewing pure cotton clothing and other pure cotton fabrics.

3. Polyester sewing thread
High strength, smooth and beautiful stitches, and wear-resistant; no mildew and no rot, low price, rich colors, not easy to fade, and no shrinkage.
4. Polyester/cotton sewing thread
Made of 65% polyester staple fiber and 35% cotton fiber blended, the thread has high strength, good abrasion resistance, low shrinkage, good flexibility and elasticity, and good heat resistance. Can sew all kinds of clothes.
5. Nylon sewing thread
Strong elongation, good elasticity, smooth texture, silky luster, and excellent abrasion resistance
