Abstract
Abstract In a process and apparatus for coloring a pile fabric, liquid coloring material is introduced into compartments, and the pile fabric is pressed face downwardly into the compartments. In order to provide regions wherein different colors are distinct from one another, a resilient barrier is provided between compartments to which different colored liquid coloring material is introduced and in order to provide areas of the pile fabric wherein the colors are blended, liquid coloring material of different colors is introduced into the compartments in regions not separated by a resilient barrier.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
In a process for the application of color designs to pile fabrics including introducing determined amounts of liquid color materials, at spaced apart points, into a receptacle having at least one resilient barrier for defining color transistions and positioned between a pair of said points, and then pressing the pile face of the pile fabric into the receptacle, whereby the color materials in the receptacle impregnate the pile fabric to provide a color design in the pile fabric; the improvement wherein said step of introducing color materials into said receptacle comprises introducing first and second liquid color materials of different color into said receptacle at first and second adjacent points respectively between which said flow of liquid materials is not inhibited by said resilient barrier, whereby said first and second liquid materials intermix in a region between said first and second points to color the portion of said pile fabric pressed into said region with a color that is a blend of the colors of said first and second liquid materials.
Claim 2
Dependent Claim
171 words
In a process for the application of color designs to pile fabrics including introducing determined amounts of liquid color materials, at spaced apart points, into a receptacle having at least one resilient barrier for defining color transistions and positioned between a pair of said points, and then pressing the pile face of the pile fabric into the receptacle, whereby the color materials in the receptacle impregnate the pile fabric to provide a color design in the pile fabric; the improvement wherein said step of introducing color materials into said receptacle comprises introducing first and second liquid color materials of different color into said receptacle at first and second adjacent points respectively between which said flow of liquid materials is not inhibited by said resilient barrier, whereby said first and second liquid materials intermix in a region between said first and second points to color the portion of said pile fabric pressed into said region with a color that is a blend of the colors of said first and second liquid materials.
Claim 3
Dependent Claim
38 words
The process of claim 1 wherein a given area of said receptacle is defined by a single barrier, said step of introducing comprising introducing said first and second liquid coloring materials at spaced apart points in given area.
Claim 4
Dependent Claim
79 words
The process of claim 1 wherein first and second adjacent areas of said receptacle are partially defined by a barrier between them, said barrier being interrupted at one common boundary region between said areas, wherein said step of introducing comprises introducing said first liquid coloring material into said first area and introducing said second liquid coloring material into said second area, whereby said first and second liquid coloring materials intermix and blend in the region of said common boundary.
Claim 5
Dependent Claim
32 words
The process of claim 1 wherein said step of introducing comprises additionally introducing liquid coloring materials of different color to adjacent areas of said receptacle which are separated by said resilient barrier.
Claim 6
Dependent Claim
70 words
A multi-colored pile fabric having on its pile face first and second adjacent colored regions of different color that are sharply defined at the boundary therebetween, and third and fourth adjacent regions of different color, the colors of said third and fourth regions being intermixed and blended in a multitude of shades of blending of the colors of said third and fourth regions and between said third and fourth regions.
Claim 7
Dependent Claim
70 words
A multi-colored pile fabric having on its pile face first and second adjacent colored regions of different color that are sharply defined at the boundary therebetween, and third and fourth adjacent regions of different color, the colors of said third and fourth regions being intermixed and blended in a multitude of shades of blending of the colors of said third and fourth regions and between said third and fourth regions.
Claim 8
Dependent Claim
148 words
In an apparatus for coloring the pile face of a pile fabric, wherein a receptacle is provided having upstanding resilient walls for containing liquid coloring material in a determined manner, means for introducing liquid coloring material of different colors to said receptacle, and means for pressing the pile face of a pile fabric into said receptacle to be colored by liquid coloring material therein; the improvement wherein a given area of said receptacle, defined at its periphery by a continuous wall, comprises a plurality of spaced apart ports for introducing liquid coloring material into said receptacle, means for introducing liquid coloring material of a first color into at least one of said ports, and means for introducing liquid coloring material of a different color to another of said ports, whereby said liquid coloring material may intermix in said area in the region between said one and other ports.
Claim 9
Dependent Claim
148 words
