  • Hybrid yarn comprising a core of intermixed polyamide filaments and reinforcing rilaments wherein the core is wrapped by a polyamide fiber
    Patent number: 5464684
    Abstract: A hybrid yarn which comprises an intimate blend of reinforcing fibers and matrix-forming thermoplastic fibers made of low viscosity polyamide and has been overwrapped with a further polyamide yarn is useful for producing laid, woven, knitted, braided and wound structures, which in turn can be consolidated into fiber composites.

  • Production of hybrid yarn
    Patent number: 5177840
    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.
