Production technology of polyester sewing thread Take a look at the production process of polyester sewing thread.
Production process of polyester staple fiber sewing thread, sewing thread, Bondi thread, nylon thread, polyester thread, along the ridge of the plant industry, PSF sewing thread production process consists of the following steps:
1 Blue and white winding: pour polyester staple fibers into the turntable, and disrupt the original regular fibers to form crimped fiber blocks;
2 Carding and stitching, the card will continue to card large pieces of fiber and splice them into small strips;
3 rovings, yarns: rovings, spinning counts to be transferred into fiber ribbons, such as 50S, 40S, 20S, 30S and other yarns;
4 Splicing and twisting: The splicer twists the single yarn into the required number of strands, such as 50s / 2, 40s / 2, 20s / 2, 30s / 3, etc.
5 twisted, loose tubes: these strands are made into a strand or a tube, ready to be dyed;
6 Dyeing and packaging: color dyeing and tube shipment according to customer needs.
Sewing threads are threads used to sew textile materials, plastics, leather products, books, etc. The sewing thread has the characteristics of sewability, durability and appearance quality. Due to different materials, sewing threads can be divided into three types: natural fiber type, chemical fiber type and mixed type. Due to different materials, sewing threads also have their unique characteristics:
The most commonly used is long-pile cotton yarn, which is made of long-hair cotton and is combed, cleared, mercerized, and twisted at high density, so the tension is better than ordinary combed cotton. Generally divided into general combing and combing two parts, 100% pure cotton thread can be used for sewing all combed cotton. It is usually used over 402202203. It is made of high-quality cotton combed and fired in the cotton area. Cotton thread is often used to sew cotton fabrics such as cotton clothing.
Composed of 65% polyester staple fiber and 35% cotton blend, high strength thread, good abrasion resistance, toughness and good elasticity, small flexibility shrinkage, good heat resistance. Sewing clothes can be various.
