This spandex covered yarn has the advantages of Nylon and Spandex, which make up the defects of a single component filament, so it has been paid more and more attention. The traditional spandex covered yarn is mainly produced by two-step method, that is, the nylon yarn is loaded on the projectile machine and then covered with air cladding machine and spandex filament, but the conventional two-step process is cumbersome and the cost is high. Therefore, the one-step process for the production of coated yarn (that is, projecting and emptying on the same machine) came into being. Compared with the two-step method, the one-step method not only improves the production efficiency, reduces the cost, but also changes product performance.
