    Abstract: 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.

    Abstract translation: 具有阳离子可染性尼龙(通常为6号尼龙适当磺化)的双组分纤维作为主要组分,用少量聚酯的紧密熔融共混物用阴离子染料染色以提高耐光性,耐臭氧性,并提供耐 酸性污渍。 纤维可能被簇绒成耐酸性污渍的地毯。 双组分纤维的两种组分可以来自再循环的来源,使得除加工添加剂之外的100%的纤维是基于消费后的再生聚合物。
