  • There are many kinds of functional fabric knitted from two threads, i.e., Spandex and Polyester, on the market. The defects of the two-thread knitting method are mainly that the two sides of the fabric have the same composition and limited to single function. The fabric knitted from three threads, i.e., the bottom yarn and the elastic fiber, is relatively rare. The advantages of the three-thread knitting method compared with the two-thread knitting method are mainly that the two sides of the fabric have different components and different functions, which can serve different needs. For example, in three-thread knitting method, Polyester is a long-staple fiber, but the fabric knitted therefrom is less hygroscopic. If it is worn in summer, there will be a more obvious sultry feeling, and sweating will irritate the skin, which affects the wearing comfort of the fabric. Knitting fabrics with three-thread knitting method requires larger knitting works, and since the yarn feed count is halved, the capacity is less than half. In addition, three-thread fabrics need different dyestuffs to dye. Different component of the fabric and may easier resulting in color shading.
