  • High speed process for making fully-oriented nylon yarns
    Patent number: 5558826
    Abstract: A coupled spin-draw process for making a fully-oriented nylon yarn including extruding molten nylon polymer with a selected RV through a spinneret and cooling to produce a yarn. The yarn is withdrawn from the quench zone with a feed roll rotating at a speed of at least 4500 mpm. The process further includes cold drawing followed by relaxing the yarn using a steam intermingling jet and then winding up.

  • Multifilament apparel yarns of nylon
    Patent number: 5202182
    Abstract: Incorporating a minor amount of a hydrogen bonding additive such as nylon 6 monomer or 2-methyl-pentamethylene adipamide monomer in a nylon 66 high RV polymer for making nylon 66 POY provides unexpected downstream advantages over homopolymer nylon 66 POY, especially in draw-texturing to make bulky yarns for use in hosiery.
