STAIN-RESISTANT POLYAMIDE FIBERS AND ARTICLES COMPRISING SAME

摘要

An acid-dye and coffee stain resistant carpet has sheath/core bicomponent fa ce fibers affixed in a backing material and bound thereto. The face fibers have a core of a first polyamide component and a sheath which substantially or completely covers the core of a second polyamide component which is inherently chemically compatib le with the first polyamide component. In an uncolored state, the carpet has a red drink staining depth of less than 15 CIE .DELTA.E units and a coffee staining dept h of less than about 10 CIE .DELTA.E units.
