Abstract
Abstract A pattern is placed on a porous transfer sheet by the use of sublimable dyes. Carpet face yarns are tufted into a backing material. The transfer sheet is placed adjacent the back of the carpet on the side of the carpet opposite from the carpet face yarns. Heated air causes the sublimable dye to move from the transfer sheet, through the carpet backing to the face yarns of the carpet to provide the dye pattern on the face yarns.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
A process for making a decorative carpet through the use of sublimable dyes comprising the steps of: a. printing sublimable dyes on a porous transfer sheet, b. preparing a carpet prouct which has on one side thereof carpet yarn forming the face fiber yarns with an irregular surface to form a sculptured pile c. placing the transfer sheet adjacent the back of the carpet product on the side of the carpet product opposite from the side of the carpet product having the face fiber yarns so that the transfer sheet with the sublimable dyes printed thereon will be adjacent the back of the carpet product, and d. transferring the sublimable dyes from the transfer sheet to the carpet face yarn through the application only of a directional flow, heated gaseous medium passing through the transfer sheet and the carpet product in the direction from the transfer sheet towards the back of the carpet product and out the face fiber yarn side of the carpet product.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
76 words
A process for making a decorative carpet according to claim 1 wherein the directional flow, heated gaseous medium is supplied at a flow rate as low as about 10 standard cubic feet per minute per square foot and preferably 10 to 120 standard cubic feet per minute per square foot and the porosity of the transfer sheet and carpet product is sufficient to permit the passage of the gaseous medium therethrough at the aforesaid flow rates.
Claim 4
Dependent Claim
42 words
The process for making a decorative carpet as set forth in claim 2 wherein the gaseous medium is supplied at a temperature ranging from about 300° to 450° F. and the dye transfer time ranges from about 30 seconds to 15 minutes.
