Process of dyeing bi-constituent fibers, process of preparing a nylon carpet and nylon carpet composed of bi-constituent fibers

Bi-constituent fibers having a cationic dyeable nylon, usually type 6 nylon adequately sulfonated, as the major component with an intimate melt blend of a minor amount of a polyester are dyed with an anionic dye to improve lightfastness, ozone resistance and to provide resistance to acid-type stains...

Zusammenfassung:	Bi-constituent fibers having a cationic dyeable nylon, usually type 6 nylon adequately sulfonated, as the major component with an intimate melt blend of a minor amount of a polyester are dyed with an anionic dye to improve lightfastness, ozone resistance and to provide resistance to acid-type stains. The fibers may be tufted into carpets that are resistant to acid-type stains. Both components of the bi-constituent fiber may come from recycled sources so that 100% of the fiber, excluding processing additives, is based on post consumer recycled polymer.
