Bicomponent fibers are two or more polymer melts separated by a special distribution plate and extruded through the same spinneret hole. There are hundreds of types of bicomponent fibers, and there are many classification methods. According to the bicomponent yarn production method, it can be divided into composite spinning and blended spinning. The fibers produced by JWELL bicomponent yarn machine not only have the advantages of nylon wear resistance, high strength, easy dyeing and moisture absorption, but also have the advantages of polyester, such as good elasticity, good shape retention, good rigidity and not easy to iron.
