Abstract

Abstract Pile fabrics prepared from nylon carpet fibers having a textured or embossed surface and a process of developing the textured effect which comprises selectively contacting the surface of said carpet with a chemical fiber shrinking agent therefore, allowing the shrinking action to occur and, thereafter, effectively removing the shrinking agent from the surface, said shrinking serving to reduce the height of the pile in the treated areas and creating said textured surface.

Claims Analysis

Total Claims: 31
Claim 1
Independent Claim 132 words
A PROCESS FOR PRODUCING AN EMBOSSED EFFECT ON NYLON PILE FABRIC HAVING A SURFACE OF NYLON FIBERS WHICH COMPRISES, APPLYING TO DEFINED AREAS OF THE PILE SURFACE OF SAID FABRIC A CHEMICAL EMBOSSING AGENT FOR SAID FIBERS, SAID AGENT BEING BLENDED INTO A LIQUID BASE VEHICLE AND BEING A METAL HALIDE AND AN ACID, ALLOWING SAID EMBOSSING AGENT IN ITS VEHICLE TO REMAIN IN CONTACT WITH SAID FIBERS FOR A PERIOD OF TIME AND AT A TEMPERATUE SUFFICIENT TO REDUCE THE HEIGHT OF SAID PILE, WITHOUT DETERIORATION OF SAD FIBERS AND, THEREAFTER, EFFECTIVELY REMOVING THE EMBOSSED AGENT FROM THE FABRIC, SAID REDUCTION IN HEIGHT OF THE FIBERS BEING IN THE AREA CONTACTED BY SAID EMBOSSING AGENT ONLY AND BEING A REDUCTION SUFFICIENT TO DISPLAY A SIGNIFICANT EMBOSSED EFFECT IN THE OVERALL FABRIC.
Claim 2
Dependent Claim 132 words
A PROCESS FOR PRODUCING AN EMBOSSED EFFECT ON NYLON PILE FABRIC HAVING A SURFACE OF NYLON FIBERS WHICH COMPRISES, APPLYING TO DEFINED AREAS OF THE PILE SURFACE OF SAID FABRIC A CHEMICAL EMBOSSING AGENT FOR SAID FIBERS, SAID AGENT BEING BLENDED INTO A LIQUID BASE VEHICLE AND BEING A METAL HALIDE AND AN ACID, ALLOWING SAID EMBOSSING AGENT IN ITS VEHICLE TO REMAIN IN CONTACT WITH SAID FIBERS FOR A PERIOD OF TIME AND AT A TEMPERATUE SUFFICIENT TO REDUCE THE HEIGHT OF SAID PILE, WITHOUT DETERIORATION OF SAD FIBERS AND, THEREAFTER, EFFECTIVELY REMOVING THE EMBOSSED AGENT FROM THE FABRIC, SAID REDUCTION IN HEIGHT OF THE FIBERS BEING IN THE AREA CONTACTED BY SAID EMBOSSING AGENT ONLY AND BEING A REDUCTION SUFFICIENT TO DISPLAY A SIGNIFICANT EMBOSSED EFFECT IN THE OVERALL FABRIC.
