Abstract
An apparel textile yarn comprising a polyamide, wherein the polyamide comprises a nylon and a polyetheramine, wherein the polyetheramine has a molecular weight of at least 1500, an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than the idealized AHEW for the polyetheramine, and wherein the polyamide may have a moisture regain ranging from about 10% to about 30%.
Claims44
An apparel textile yarn comprising:
- a polyamide, the polyamide comprising a nylon and a polyetherdiamine, the polyetherdiamine having a weight-average molecular weight (Mw) of at least 1500 and an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than an idealized AHEW for the polyetherdiamine, wherein a number of active amine hydrogens per molecule, and the AHEW, is calculated by determining an amine group nitrogen content using a procedure described in ISO 9702.
An apparel textile yarn of claim 13, wherein the polyetherdiamine is present in an amount ranging from about 5 wt % to about 15 wt % by weight, and in one embodiment from about 8 wt % to about 18 wt %, and in a further embodiment from about 10 wt % to about 15 wt %.
An apparel fabric comprising:
- an apparel textile yarn comprising a polyamide, the polyamide comprising a nylon and a polyetherdiamine, the polyetherdiamine having a weight-average molecular weight (Mw) of at least 1500 and an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than an idealized AHEW for the polyetherdiamine, wherein a number of active amine hydrogens per molecule, and the AHEW, is calculated by determining an amine group nitrogen content using a procedure described in ISO 9702.
A garment comprising:
- an apparel fabric comprising an apparel textile yarn, said apparel textile yarn comprising a polyamide, the polyamide comprising a nylon and a polyetherdiamine, the polyetherdiamine having a weight-average molecular weight (Mw) of at least 1500 and an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than an idealized AHEW for the polyetherdiamine, wherein a number of active amine hydrogens per molecule, and the AHEW, is calculated by determining an amine group nitrogen content using a procedure described in ISO 9702.
A process for producing an apparel textile yarn from a polyamide, the process comprising:
- extruding a molten polyamide through a spinneret plate containing capillary orifices, and forming an apparel textile yarn from filaments emerging from the spinneret plate, the polyamide comprising a nylon and a polyetherdiamine, the polyetherdiamine having a weight-average molecular weight (Mw) of at least 1500 and an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than an idealized AHEW for the polyetherdiamine, wherein a number of active amine hydrogens per molecule, and the AHEW, is calculated by determining an amine group nitrogen content using a procedure described in ISO 9702.
