Abstract
Hybrid yarn is produced from thermoplastic and reinforcing fibers by spreading the fibers separately to form a band and combining and homogeneously intermixing the two bands on rolls or rods. The spreading is carried out in such a way that the reinforcing fiber band will be from 20 to 100% wider than the thermoplastic fiber band. The hybrid yarn can be sized and processed into fabrics which can be molded to produce fiber composites.
