Abstract
Abstract Multicolored pile materials, and particularly pile carpets, comprising a fabricated backing and a fabricated pile face having: (1) upper pile face portions which have a predetermined color; and (2) lower pile face portions which have a color which is different and darker than the predetermined color of the upper pile face portions, whereby unusual multicolored effects are obtained; and, more specifically, multicolored pile fabrics, and particularly pile carpets, comprising a fabricated backing and a fabricated pile face having: (1) upper pile face portions which are substantially white in color; and (2) lower pile face portions which have a color which is different and darker than white, whereby unusual multicolored, frosted effects are obtained. Processes for making such multicolored or frosted pile materials are also included.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
182 words
A process of creating unusual multicolored effects in pile materials comprising a fabricated backing and a fabricated pile face which comprises: treating the upper portions and the lower portions of the pile face of the pile materials with a dye; treating only the upper portions and not the lower portions of said pile face with a resist chemical material, while said pile face and said dye are still wet and before said dye has been set, said resist chemical material being capable of displacing said dye from said upper portions of said pile face and changing the dye receptivity of said upper portions of said pile face; exposing said upper portions and said lower portions of said pile face of said pile materials to a dye setting treatment while said pile face is still wet, which sets said dye in the lower portions of said pile face without setting said dye in the upper portions of said pile face; and washing said pile materials to remove from said upper portions said resist chemical material and said dye which was not set therein.
Claim 2
Dependent Claim
182 words
A process of creating unusual multicolored effects in pile materials comprising a fabricated backing and a fabricated pile face which comprises: treating the upper portions and the lower portions of the pile face of the pile materials with a dye; treating only the upper portions and not the lower portions of said pile face with a resist chemical material, while said pile face and said dye are still wet and before said dye has been set, said resist chemical material being capable of displacing said dye from said upper portions of said pile face and changing the dye receptivity of said upper portions of said pile face; exposing said upper portions and said lower portions of said pile face of said pile materials to a dye setting treatment while said pile face is still wet, which sets said dye in the lower portions of said pile face without setting said dye in the upper portions of said pile face; and washing said pile materials to remove from said upper portions said resist chemical material and said dye which was not set therein.
Claim 3
Dependent Claim
37 words
