Method of treating yarns to provide kinking and/or mottled effects in fabrics

Abstract

The placing of a plurality of yarns into a woven fabric form of a type where the filling yarn may be easily unwoven so as to treat the warp yarns either by means of a color, bulking, or setting into a kinked effect or all of them and then unweaving the woven fabric to provide a plurality of similarly treated yarns for reworking into various forms such as fabrics.

We claim: 
     
       1. The method of simultaneously treating a plurality of yarns which comprises providing a plurality of relatively large warp yarns, weaving in a selected fabric construction said warp yarns with .[.a.]. .Iadd.one single continuous .Iaddend.filling yarn of a relatively smaller diameter than said warp yarns and disposed with relation to said warp yarns .Iadd.a greater distance apart than the warp yarns and .Iaddend.in .Iadd.knit-like loops along one edge, each filling yarn loop knitted to the preceding loop to provide .Iaddend.a continuous unweavable relation .[.,.]. .Iadd.from one end only, .Iaddend.coloring said fabric .Iadd.while in said unweavable relation .Iaddend.to color the warp yarns, the weave selection providing the character of the kink imparted to the warp yars.Iadd., moving said fabric to another station .Iaddend.and .[.unweaving.]. .Iadd.continuously pulling on said filling yarn to unweave .Iaddend.said filling yarn .Iadd.and then packaging the separated warp yarns .Iaddend.to provide a plurality of colored .Iadd.warp .Iaddend.yarns of controlled kink character ranging from no .Iadd.perceptible .Iaddend.kink to high kink amplitude for reworking into various forms. 
     
     
       2. The method of claim 1 wherein said coloring is intermittent to provide mottled yarns.  .[.3. The method of claim 1 wherein said colored yarns are 
     
     
        intermeshed into fabric form..]. 4. The method of claim 1 wherein after coloring and prior to removal of the filling yarn, the fabric is heat set to maintain a kink in the warp yarns provided by the insertion of the 
     
     
        filling yarn. 5. The method of claim 4 wherein said colored yarns are 
     
     
        intermeshed into fabric form. 6. The method of simultaneously treating a plurality of yarns which comprises providing a plurality of relatively large warp yarns, weaving in a selected fabric construction said warp yarns with a .Iadd.continuous .Iaddend.filling yarn of a relatively smaller diameter than the warp yarns and disposed with relation to said warp yarns .Iadd.a greater distance apart than the warp yarns and .Iaddend.in .Iadd.knit-like loops along one edge, each filling yarn loop knitted to the preceding loop to provide .Iaddend.a continuous unweavable relation .Iadd.from one end only .Iaddend.and heat treating said fabric to allow it to bulk the warp yarns, the weave selection providing the character of the kink imparted to the warp yarn, .[.and unweaving.]. .Iadd.moving the fabric to another station and continuously pulling on said filling yarn to unweave .Iaddend.said filling yarn .Iadd.and then packaging the separated warp yarns .Iaddend.to provide a plurality of .Iadd.warp .Iaddend.yarns of controlled kink character ranging from no .Iadd.perceptible .Iaddend.kink to high kink amplitude for reworking into various forms.
