In addition to the sewing function, the sewing thread also plays a decorative role. The amount and cost of sewing thread may not account for a small proportion of the whole garment, but sewing efficiency, sewing quality and appearance quality are very important. One of the most difficult things to grasp.​
cotton, silk
The ingredients of natural fibers are mainly cotton and silk. Cotton fiber sewing thread has good strength and excellent heat resistance. It is suitable for high-speed sewing and durable pressing, but its elasticity and wear resistance are slightly poor. In addition to ordinary soft threads, there are wax threads and mercerized threads of cotton threads after sizing and waxing. Wax rays are improved in strength and abrasion resistance, which reduces frictional resistance when sewing. Suitable for sewing stiff and leather fabrics. The silk light texture is soft and shiny, the strength is also improved, and the hand feel is smooth and mostly used in high-end cotton products. Since the post-processing of cotton sewing thread by domestic related equipment has not reached the desired toughness, the cotton thread is still easy to break in the impression. Therefore, the scope of cotton thread is not very wide. Silk thread is superior to cotton thread in terms of gloss, elasticity, strength, abrasion resistance, etc., but it is obviously inferior in price. It is mainly suitable for sewing silk and high-end clothing, but its heat resistance and strength are lower than polyester filament thread. . Therefore, the commonly used polyester thread in synthetic fibers.
Polyester, polyester bomb
Polyester thread is widely used in garment sewing of cotton fabric, chemical fiber and blended fabric due to its high strength, low shrinkage rate, abrasion resistance and good heat resistance. Polyester has filament, short and polyester low elastic yarn. Among them, polyester staple fiber is mainly used to sew various types of cotton, polyester-cotton chemical fiber, wool and blended fabrics, and is currently the most widely used sewing thread. The most used in the sewing of knitted garments such as sportswear, underwear, and tights are elastic polyester low-elastic silk threads and nylon strong threads. In addition, polyester and silk in mixed fibers are better than pure polyester in terms of flexibility, gloss and toughness, so they are used in a wider range. The use of ultra-thin fabrics naturally requires polyester and nylon yarns.
Nylon, blended
Nylon thread has good abrasion resistance, high strength, bright luster and good elasticity. Because of its poor heat resistance, it is not suitable for high-speed sewing and high-temperature ironing fabrics. The commonly used nylon filament thread is suitable for the sewing of chemical fiber clothing and the button and lock button of various clothing. The application range of nylon and nylon monofilament is for some elastic fabrics, that is, fabrics with relatively high tension. Belt loops, cuff cuffs and hem topstitching on Chinese garments.
The blended yarns are mainly polyester-cotton blended and core-spun yarns. The polyester-cotton thread is made of polyester-cotton blend in a ratio of about 65:35. This kind of thread has better wear resistance and heat resistance, and the thread quality is soft, and it is also suitable for sewing and edging of various cotton fabrics, chemical fibers and knitting. The core thread is made of cotton on the outside and polyester on the inside. Because of this structure, the core thread has high strength, soft and elastic thread quality, and low shrinkage rate. It has the dual characteristics of cotton and polyester and is suitable for high-speed sewing of medium and thick fabrics. These kinds of sewing threads also have broad application potential.
gold wire, silver wire
The characteristics of silk decorative thread are bright colors, elegant and soft color; rayon decorative thread is made of viscose, although the gloss and hand feel are good, but the strength is slightly inferior to silk. In addition, the decorative effect of gold and silver threads has been paid more and more attention. Gold and silver thread, also known as craft decoration thread, is obtained by coating polyester fiber with color coating. Patterns, topstitching and partial decoration for Chinese clothing and fashion.
