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.
