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 large proportion of the entire garment, but the sewing efficiency, sewing quality and appearance quality are related to this. What kind of fabric and what kind of thread are used in which situation is One of the most difficult things to master.
Cotton, silk
The composition of natural fiber is mainly cotton and silk. The sewing thread of cotton fiber has good strength and excellent heat resistance. It is suitable for high-speed sewing and durable pressing, and its elasticity and wear resistance are slightly worse. In addition to ordinary soft threads, there are wax rays of cotton threads after sizing and waxing and silk rays of mercerizing. The wax light has improved in strength and wear resistance, so that the friction resistance during sewing can be reduced. Suitable for sewing of stiff fabrics and leather fabrics. The silk light texture is soft and shiny, and its strength has also been improved. It has a smooth feel and is mostly used for high-end cotton products. Because the post-processing of cotton sewing thread by domestic related equipment has not reached the ideal toughness, cotton thread is still easy to break in the impression. Therefore, the scope of cotton yarn is not very wide. Silk thread is superior to cotton thread in terms of gloss, elasticity, strength, wear resistance, etc., but it is obviously at a disadvantage in terms of price. It is mainly suitable for sewing silk and high-end clothing, but its heat resistance and strength are lower than polyester filament . Therefore, commonly used polyester threads in synthetic fibers.
Polyester, polyester bomb
Polyester thread is widely used in the sewing of cotton fabrics, chemical fibers and blended fabrics due to its high strength, low shrinkage, wear resistance and good heat resistance. There are several types of polyester filament, short filament 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 yarn, and is currently the most widely used sewing thread. The most commonly used in the sewing of knitted apparel such as sportswear, underwear and tights is the elastic polyester low elastic yarn and nylon strong thread. In addition, the polyester and silk in the mixed fiber are better than the pure polyester in terms of flexibility, gloss and toughness, so the range of use is wider, and the use of ultra-thin fabrics naturally requires polyester and nylon.
Nylon, blended
Nylon thread has good wear resistance, high strength, bright luster and good elasticity. Due to its slightly 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 sewing chemical fiber clothing and the button and lock button of various clothing. Nylon and nylon monofilaments are suitable for some stretch fabrics, that is, fabrics with relatively high tension. They are mostly used in the edging, cuffs, cuffs and buttons in the manual operation of clothing. In addition, they can be used in decorative ropes such as women's clothing. Belt loops, cuffs and Chinese style clothing cuffs and hem line decoration.
The blended yarns are mainly polyester-cotton blended and core-spun yarns. The polyester-cotton thread is made of polyester-cotton blended yarn, the ratio is about 65:35. This type of thread has better wear resistance and heat resistance, and the thread is soft. It is also suitable for the sewing and copying of various cotton fabrics, chemical fibers and knitting. The core-spun yarn is cotton on the outside and polyester on the inside. Due to the high strength of this structure, the thread is soft and elastic, with low shrinkage. It has the dual characteristics of cotton and polyester and is suitable for high-speed sewing of medium-thick fabrics. These kinds of sewing threads also have broad potential for use.
Gold wire, silver wire
The characteristic of the silk decoration thread is that it is bright in color, and the color is more elegant and soft; the rayon decoration thread is made of viscose, although the gloss and feel are both good, but it is slightly inferior to the silk in strength. In addition, the decorative effect of gold and silver wire is getting more and more attention. Gold and silver thread, also known as craft decoration thread, is obtained by applying colored coating on polyester fiber. It is used for patterns, open threads and partial decoration of Chinese clothing and fashion.
