In addition to the stitching function, the sewing thread also plays a decorative role. The amount and cost of sewing thread may not be a large proportion in the whole garment, but the sewing efficiency, sewing quality and appearance quality are related to this. What kind of fabric is used under what circumstances? One of the least easy things to master.

Cotton Yarn & Silk

The main components of natural fiber are cotton and silk. The cotton fiber has good sewing thread strength and excellent heat resistance. It is suitable for high-speed sewing and durable pressing, and its elasticity and wear resistance are slightly poor. In addition to the ordinary cord, there are also wax rays and mercerized silk rays after the cotton is sizing. The wax light is improved in strength and wear resistance, which reduces the frictional resistance during sewing. Suitable for sewing on stiff fabrics and leather fabrics. The silk light texture is soft and lustrous, the strength is also improved, and the smoothness of the hand is mostly used for medium and high-grade cotton products. Because the post-processing of cotton sewing thread by domestic related equipment did not reach the ideal toughness, the cotton thread is still easily broken in the impression. Therefore, the scope of the cotton thread is not very wide. The thread is superior to cotton in terms of gloss, elasticity, strength and wear resistance, but it is obviously at a disadvantage in terms of price. It is mainly suitable for sewing silk and high-grade garments, but its heat resistance and strength are lower than polyester filament yarn. . Therefore, the polyester thread in the synthetic fiber is commonly used.

Polyester Yarn & Polyester Elastic Yarn

Polyester thread is widely used in the sewing of cotton fabrics, chemical fibers and blended fabrics due to its high strength, low shrinkage, abrasion resistance and heat resistance. Polyester has several kinds of filaments, short filaments and polyester low-elastic yarns. Among them, polyester staple fiber is mainly used for sewing all kinds of cotton, polyester-cotton chemical fiber, wool and blended fiber. It is the most widely used sewing thread. The most used in the sewing of knitted garments 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 more widely used in terms of flexibility, gloss and toughness, so the use range is wider, and the use of ultra-thin fabrics naturally requires polyester yarn and nylon yarn.

Nylon Yarn & Blended Yarn

The 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. The commonly used nylon filament thread is suitable for the sewing of chemical fiber garments and the buckles and lock buttons of various garments. The range of nylon and nylon monofilament is for some elastic fabrics, that is, fabrics with relatively high tension. They are mostly used for the edges, pants, sleeves and buttons in the manual operation of garments, and can also be used in decorative ropes such as women's clothing. The belt buckles, the cuffs of the Chinese clothing and the open line of the hem.

The blended yarn is mainly composed of polyester-cotton blend and core-spun yarn. The polyester/cotton thread is made of polyester-cotton blend, with a ratio of approximately 65:35. This linear shape has good wear resistance and heat resistance, and the thread is soft, and it is also suitable for sewing and copying of various cotton fabrics, chemical fibers and knitting. The outer core of the core wire is cotton, and the inside is polyester. Due to the high strength of the core wire, the thread is soft and elastic, and the shrinkage rate is small. It has the dual characteristics of cotton and polyester and is suitable for high-speed sewing of medium-thick fabrics. These sewing threads also have broad potential for use.

Gold Yarn & Silver Yarn

The characteristics of the silk decorative line are bright and the color is more elegant and soft; the rayon decorative line is made of viscose, although the gloss and feel are good, but the strength is slightly worse than the silk. In addition, gold and silver wire decoration effects have received more and more attention. The gold and silver wire, also known as the craft decoration line, is obtained by applying a color coating on the outer surface of the polyester fiber. For Chinese clothing and fashion, patterns, open lines and partial decorations.
