Sewing thread is used to sew all kinds of clothing materials and has dual functions of practicality and decoration. The quality of sewing thread not only affects the sewing effect and processing cost, but also affects the appearance quality of the finished product. Therefore, the general concept of suture formation, twist, the relationship between twist and strength, suture classification, charact
High strength polyester filament is widely used. It is a good material to replace steel, iron, copper and other metals with plastics. Twisting and shaping is the general term for short fiber yarn, real silk and chemical fiber filament with twist.
High strength polyester thread is mainly used to sew all kinds of cotton, polyester cotton chemical fiber, wool and blending processes.
High strength sewing thread, also known as terylene thread and polyester thread, is made of continuous polyester high strength and low elongation yarn. It is temperature resistant to 130 degrees, high tension, low elongation and no elasticity.
Generally speaking, the domestic marine industry is mainly made of polyester rope and polypropylene rope. These two kinds of ropes have prominent advantages in light resistance and acid and alkali resistance, but their strength, aging resistance and other properties are in an absolute inferior position compared with the new fiber ropes.
Aramid fiber has very high strength, the weight ratio tensile strength is 6 times of steel wire, 3 times of glass fiber, and 2 times of high strength nylon industrial yarn; its tensile modulus is 3 times of steel wire, 2 times of glass fiber and 10 times of high strength nylon industrial yarn; the continuous service temperature range of aramid fiber is extremely wide, ranging from - 196.
High strength and low elongation special composite sewing thread uses two filaments, so its yarn forming performance has the characteristics of high, no knot and even.
The reflective rope is made of reflective strip and chemical fiber regularly. On the basis of ordinary rope, the reflective function is added. In the dark, when the light shines on the rope, the reflective material will reflect the light and improve the safety performance
