Introduction to sewing thread
The sewing thread is the thread required for knitting luggage products. The sewing thread can be divided into three categories: natural fiber, synthetic fiber sewing thread and mixed sewing thread. With the development of the polyester industry, the sewing thread uses more and more pure polyester fiber as its raw material.
The single yarn count of sewing thread is generally 9-80 British, the total number of shares is 3 shares, and there are also 2, 4 and 6 shares, up to 24 shares. More than 6 sewing threads are commonly used in the leather, canopy and footwear industries.
There are many types of sewing thread, and in the era of hand sewing, it is mainly twisted cotton and silk. With the use of the sewing machine, a wooden yarn group appeared, that is, the waxed cotton thread was wound around the wooden core, followed by a paper core (or plastic core) wire, a cardboard wire, a wire ball, a pagoda wire, and the like. The capacity of various packages varies according to civilian and industrial use. Civil sewing thread, such as wood yarn, paper core, cardboard wire and wire ball, the length is 50-1000 meters; Guangzhou Kangfa Textile Co., Ltd. is specialized in producing silk light, German light, high strength wire, wax wire, transparent wire , the company of polyester sewing thread. The length of the industrial sewing thread package is 1000~11000 meters, which is generally wound on the cone tube or the edged tube, which is called the pagoda line or the plywood tube line.
Sewing thread specifications
1. Nylon thread (Nylon 6, Nylon 6.6)
Kangfa nylon thread, also known as nylon thread and pearl light, is made of continuous filament nylon fiber. It is smooth and soft, with an elongation of 20%--35%.

Characteristics and uses of various sewing threads
Cotton sewing thread
Good heat resistance, poor elasticity, abrasion resistance, moisture resistance and antibacterial ability, suitable for high speed sewing and durable pressing.
Polyester sewing thread
The strength is high, the stitches are flat and beautiful, wear-resistant; not mildew, no rot, low price, rich color, not easy to fade, not shrinking.
Polyester cotton sewing thread
Made of 65% polyester staple fiber and 35% cotton fiber blend, the wire has high strength, good wear resistance, small shrinkage, good flexibility and good heat resistance. A variety of clothing can be sewn.
Velon line
The price is lower, the breaking strength is high, the wear resistance is lower than that of the nylon thread, and the chemical stability is good. The main sewing is various flour bags, cloth shoes uppers, canvas, lock eyes, and buckles.
Nylon thread
High breaking strength, good wear resistance, low moisture absorption, high elasticity, but insufficient heat resistance, generally controlled at about 120 °C. Generally used for sewing chemical fiber fabrics, woolen sweaters, sweaters, etc.
Silk thread
The surface is smooth, the gloss is soft, the elasticity is good, and the temperature is high. Rayon is brightly colored, but its strength is poor, its moisture absorption is poor, and its price is cheaper. It is used for sewing woolen garments and satin fabrics, and is mostly used for machine embroidery.
Nylon sewing thread
Large pulling force, good elasticity, smooth texture, silky luster, excellent wear resistance; mainly suitable for leather sewing, such as: footwear, bag industry, sofa industry, etc. Nylon thread is the most common leather sewing thread.
