Polyester thread, made of polyester filament or staple fiber, has high strength, good elasticity, wear resistance, low shrinkage and good chemical stability. However, the melting point is low, the high speed is easy to melt, the needle eye is blocked, and the thread is easy to break. The selection of the needle should be paid attention to.
Mainly used in denim, sportswear, leather products, wool and military uniforms, etc., it is the most used and most popular sewing thread. Nylon sewing thread, made of pure nylon multifilament, divided into long thread, short fiber thread and elastic deformation line. At present, the commonly used filament thread has a large elongation and good elasticity, and the tensile length at the moment of breaking is three times larger than that of the cotton thread of the same specification. Used for sewing of chemical fiber, wool, leather and stretch garments. The biggest advantage of nylon sewing thread is transparency. Because this line is transparent and has good color, it reduces the difficulty of sewing wiring and has broad development prospects.
However, it is limited to the fact that the rigidity of the transparent wire on the market is too large, the strength is too low, the stitches are easy to float on the surface of the fabric, and the high temperature is not tolerated, and the sewing speed cannot be too high. At present, such lines are mainly used as parts that are not easily stressed, such as decals and edging.
