For the sewing of chemical fiber, woolen, leather and elastic garments. The biggest advantage of nylon sewing thread is its transparency. Because the thread is transparent and has good color, it reduces the difficulty of sewing and wiring and has a broad development prospect. However, it is limited to the fact that the rigidity of the transparent thread currently on the market is too high, the strength is too low, the stitches are easy to float on the surface of the fabric, and it is not resistant to high temperature, so the sewing speed cannot be too high. At present, this type of thread is mainly used for decals, cutting edges and other parts that are not easily stressed.
