Abstract
Abstract The process for producing unusual texturized effects in a threecomponent laminate having a facing component having upstanding fibers, a backing component and a water-insoluble interlayer component securing the facing component to the backing comprising applying a chemical shrinking agent to the fibrous component in a pre-determined design pattern, drying the fabric and washing the fabric. Also disclosed is a process for producing multi-color effects in such laminates by dyeing the laminate, applying a chemical shrinking agent to the fibers in a pre-determined design pattern, said shrinking agent being capable of changing the color of said dye, drying the laminate and then washing the laminate. Laminates obtained are described.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
78 words
A METHOD FOR PRODUCING THREE DIMENSIONAL AND VARIABLE COLOR EFFECTS IN A LAMINATE OF THE THE TYPE COMPOSED OF A BACKING LAYER, A FACING LAYER OF UPSTANDING FIBERS, AND A WATER INSOLUBLE, SUBSTANTIALLY CONTINUOUS BINDER INTER-LAYER, SECURING THE FACING LAYER OF THE BACKING LAYER, CONSISTING OF: A. SHRINKING SELECTED AREAS OF THE FACING LAYER IN A PREDETERMINED DESIGN PATTERN BY APPLYING A CHEMICAL SHRINKAGE AGENT TO SAID SELECTED AREAS; B. DRYING THE LAMINATE; AND C. WASHING THE LAMINATE.

Claim 3
Dependent Claim
13 words
The process of claim 1 wherein the fibers are nylon, cellulose, or polyacrylic.
Claim 4
Dependent Claim
81 words
The process of claim 2 wherein the fiber is nylon and the shrinking agent is an acid having a dissociation constant greater than about 2 X 10 5 and is selected from the group consisting of strong mono and polybasic inorganic acids; organic acids having the formula R-COOH wherein R is hydrogen, lower alkyl having 1 to 5 carbon atoms, halogen substituted lower alkyl having 1 to 5 carbon atoms or a nucleus of the phenyl series; sulfonic acids; and phenols.
Claim 5
Dependent Claim
45 words

Claim 6
Dependent Claim
122 words
The process of claim 2 wherein the fiber is polyacrylic and the shrinking agent is an acid having a dissociation constant greater than about 2 X 10 5 and is selected from the group consisting of strong mono and polybasic inorganic acids; organic acIds having the formula R-COOH wherein R is hydrogen, lower alkyl having 1 to 5 carbon atoms, halogen substituted lower alkyl having 1 to 5 carbon atoms; or a nucleus of the phenyl series; sulfonic acids, phenols; a salt formed from cations selected from the group consisting of Zn , Ag , Ni , Co ,Mn and an anion selected from the group consisting of SCN ,I , Br , and Cl ; a disubstituted amide having the formula
Claim 7
Dependent Claim
20 words
The process of claim 1 wherein subsequent to washing step (c), at least one component of the laminate is dyed.
Claim 8
Dependent Claim
12 words

Claim 9
Dependent Claim
31 words
The process of claim 1 wherein the fibers are dyed prior to applying the shrinking agent, and wherein the shrinking agent used is capable of changing the color of said dye.
Claim 10
Dependent Claim
20 words
The process of claim 8 wherein at least one of the components in addition to the facing component is dyed.
