In addition to the sewing function, the sewing thread also plays a decorative role. The raw materials of sewing thread are mainly polyester filament, polyester staple yarn, high-count cotton and polyester cotton. The dyeing of polyester sewing thread mostly uses disperse dyes. In order to improve the dyeing rate, it is generally dyed in a high temperature and high pressure cylinder, so the temperature of the wastewater is very high, the amount of water is small, and the biodegradability is poor.
The sewing thread is used to sew various garment fabrics and other auxiliary materials, and has the dual functions of practicality and decoration. The quality of the suture not only affects the sewing effect and processing cost, but also affects the appearance quality of the finished product. People engaged in the clothing industry must understand the general concept of stitch formation, twist, the relationship between twist and strength, stitch classification, characteristics and main uses, and the selection of stitches.
