Abstract
Abstract An improved process of developing an embossed effect in nylon pile fabric, particularly carpet, that comprises selectively contacting the pile surface of the foregoing fabric with a chemical fiber shrinking agent in combination with a penetrant vehicle capable of increasing materially the penetration of the shrinking agent into the fibre surface, and, correspondingly, the depth of embossing caused by the shrinking agent's action in reducing the length of the treated pile.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
179 words
Process for providing 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 composition for said fibers containing an embossing agent and a penetrant therefor, said embossing agent including an acid having a dissociation constant no stronger than that of maleic acid and said composition having a hydrogen ion concentration equivalent to a pH of no more than 4; said penetrant corresponding to a compound selected from: ##EQU2## wherein each of m, n, and a is an integer from 1 to 4, inclusive, X=H or CH 3 and each R and R 1 is a lower alkayl radical of 1 to 5 carbon atoms allowing said embossing composition to remain in contact with said fibers for a period of time and at a temperature sufficient to reduce the height of said pile only in the area contacted by said embossing composition, without deterioration of said fibers, said reduction being sufficient to display a significant embossed effect in the overall fabric.
Claim 2
Dependent Claim
179 words

Claim 3
Dependent Claim
26 words

Claim 8
Dependent Claim
14 words
The process of claim 2 wherein said penetrant is ethylene glycol monomethyl ether acetate.
Claim 9
Dependent Claim
26 words
The process of claim 4 wherein said embossing agent is present in a concentration of 40 percent to 50 percent by weight of total embossing composition.
Claim 10
Dependent Claim
12 words

Claim 13
Dependent Claim
16 words
The process of claim 4 wherein said embossing composition is incorporated in a transparent vehicle therefore.
Claim 14
Dependent Claim
33 words
The process of claim 4 wherein said embossing effect is made in register with a printed color design on said fabric, and said vehicle is a dye printing paste carrying said embossing agent.
Claim 15
Dependent Claim
14 words
The process of claim 4 wherein said embossing action occurs in a steam environment.
