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%.
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 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.
