  • Polyamide apparel textile yarns and fabrics and garments made therefrom
    Patent number: 9834867
    Abstract: An apparel textile yarn includes a polyamide. The polyamide includes a nylon and a polyetheramine. The polyetheramine has a molecular weight of at least 1500 and an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than the idealized AHEW for the polyetheramine. The polyamide may have a moisture regain ranging from about 10% to about 30%.
