Abstract
Abstract In a procedure for dyeing a length of fabric by conveying the fabric in the direction of its length through a dye station where the fabric is impregnated with a quick-setting dye, the dye is caused to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, by causing the fabric to pass through the station in a longitudinally twisted state. In order to enhance the effect of this procedure, and in particular to vary the general nature of the color variation produced, the fabric is manipulated ahead of the dye station by periodically varying its degree of twist and/or degree of compression transverse to its length.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
In a method for continuously dyeing a length of fabric by moving the fabric in the direction of its length through a dye station where the fabric is impregnated with a quick setting dye, the improvement comprising imparting a longitudinal twist to the fabric ahead of the dye station to cause the fabric to pass through the station in a twisted state for causing the dye to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, and then storing the fabric, while maintaining it longitudinally twisted for at least the time required for the dye which has impregnated the fabric to completely react.
Claim 2
Dependent Claim
106 words
In a method for continuously dyeing a length of fabric by moving the fabric in the direction of its length through a dye station where the fabric is impregnated with a quick setting dye, the improvement comprising imparting a longitudinal twist to the fabric ahead of the dye station to cause the fabric to pass through the station in a twisted state for causing the dye to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, and then storing the fabric, while maintaining it longitudinally twisted for at least the time required for the dye which has impregnated the fabric to completely react.
Claim 3
Dependent Claim
47 words
A method as defined in claim 1 wherein the dye station includes a rotatable dye delivery cylinder and further comprising displacing the fabric, at a point ahead of the dye station, in a cyclic manner transverse to its length and parallel to the axis of such cylinder.
Claim 4
Dependent Claim
116 words
In a method for continuously dyeing a length of fabric by moving the fabric in the direction of its length through a dye station where the fabric is impregnated with a quick setting dye, the improvement comprising imparting a longitudinal twist to the fabric ahead of the dye station to cause the fabric to pass through the station in a twisted state for causing the dye to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, and manipulating the fabric ahead of the dye station for periodically varying the degree of compression of the twisted fabric transverse to its length and the configuration of the twisted fabric as it passes through the station.
Claim 5
Dependent Claim
116 words
In a method for continuously dyeing a length of fabric by moving the fabric in the direction of its length through a dye station where the fabric is impregnated with a quick setting dye, the improvement comprising imparting a longitudinal twist to the fabric ahead of the dye station to cause the fabric to pass through the station in a twisted state for causing the dye to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, and manipulating the fabric ahead of the dye station for periodically varying the degree of compression of the twisted fabric transverse to its length and the configuration of the twisted fabric as it passes through the station.
Claim 6
Dependent Claim
22 words
A method as defined in claim 3 wherein said step of manipulating includes periodically varying the degree of twist of the fabric.
Claim 7
Dependent Claim
121 words
IN APPARATUS FOR CONTINUOUSLY DYEING A LENGTH OF FABRIC, WHICH APPARATUS INCLUDES A DYE STATION THROUGH WHICH THE FABRIC PASSES WHILE TRAVELLING IN THE DIRECTION OF ITS LENGTH AND IN WHICH THE FABRIC IS BROUGHT INTO CONTACT WITH A QUICK-SETTING DYE IN SUCH A MANNER AS TO CAUSE THE DYE TO IMPREGATE THE FABRIC, THE IMPROVEMENT COMPRISING: MEANS DISPOSED AHEAD OF SAID DYE STATION AND MOUNTED FOR ROTATION FOR IMPARTING A LONGITUDINAL TWIST TO THE FABRIC TO CAUSE THE FABRIC TO PASS THROUGH THE STATION IN A TWISTED STATE FOR CAUSING THE DYE TO NON-UNIFORMLY COLOR THE FABRIC WITH A GENERALLY LONGITUDINAL, RANDOMLY VARYING PATTERN EFFECT; DRIVE MEANS CONNECTED TO ROTATE SAID MEANS FOR IMPARTING A TWIST; AND STORAGE MEANS FOR
Claim 8
Dependent Claim

Claim 9
Dependent Claim
135 words
In apparatus for continuously dyeing a length of fabric, which apparatus includes a dye station through which the fabric passes while travelling in the direction of its length and in which the fabric is brought into contact with a quick-setting dye in such a manner as to cause the dye to impregnate the fabric, the improvement comprising means ahead of said dye station for imparting a longitudinal twist to the fabric to cause the fabric to pass through the station in a twisted state for causing the dye to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, wherein said means for imparting a twist comprises a turntable arranged to receive such length of fabric in an initially untwisted state and to rotate as fabric is conveyed therefrom to said dye station.
Claim 10
Dependent Claim
135 words
In apparatus for continuously dyeing a length of fabric, which apparatus includes a dye station through which the fabric passes while travelling in the direction of its length and in which the fabric is brought into contact with a quick-setting dye in such a manner as to cause the dye to impregnate the fabric, the improvement comprising means ahead of said dye station for imparting a longitudinal twist to the fabric to cause the fabric to pass through the station in a twisted state for causing the dye to non-uniformly color the fabric with a generally longitudinal, randomly varying pattern effect, wherein said means for imparting a twist comprises a turntable arranged to receive such length of fabric in an initially untwisted state and to rotate as fabric is conveyed therefrom to said dye station.
Claim 11
Dependent Claim
81 words
Apparatus as defined in claim 6 wherein said turntable is oriented to rotate about a substantially vertical axis and said means for imparting a twist further comprises a circular guide hoop mounted for rotation with said turntable and oriented to lie in a plane inclined to the axis of rotation of said turntable, said hoop being arranged to permit the length of fabric to pass therethrough and bear against the surface thereof while traveling from said turntable to said dye station.
Claim 12
Dependent Claim
76 words
Apparatus as defined in claim 7 further comprising: sUbsequent treating means disposed beyond said dye station; first guide means for continuously guiding such fabric from said dye station to said subsequent treating means, and second guide means disposed beyond said subsequent treating means for guiding the fabric leaving said treating means while maintaining a fixed spatial relation between said treating means and the portion of fabric extending from said treating means to said second guide means.
Claim 13
Dependent Claim
11 words
A dyed fabric produced by the method defined in claim 1.
