Abstract

Abstract A method for producing ingrain spun-like yarn simulating a blended staple yarn is described wherein continuous filament yarn is produced which has characteristics similar to blended staple spun yarns. Fabrics made from the yarns described herein provide a fine grained heather appearance without the normal moire or plaiting effect seen in previous ingrain continuous filament yarn fabrics. The unusual continuous filament yarn described herein is made by a texturing process which involves the combination of two or more differently dyeable continuous synthetic yarns which are false twist textured followed by overfeeding to an air bulking means. The preferred method utilizes false twist texturing of synthetic filaments such as polyester, nylon, cellulose acetate or cellulose triacetate and mixtures thereof wherein two differently dyeable yarns are combined with an air bulking jet interposed to act on the false twist textured yarn while it has a high residual torque and subsequently decaying said torque.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 65 words
A process for producing a continuous filament spun-like ingrain yarn comprising combining at least two differently dyeable synthetic continuous filament yarns, false twist texturing said combined yarn to produce a torque lively yarn, overfeeding said textured yarn to a high velocity gaseous jet to convolute individual filaments in the yarn to form a plurality of torque induced kinks and winding said yarn onto a package.
Claim 2
Dependent Claim 65 words
A process for producing a continuous filament spun-like ingrain yarn comprising combining at least two differently dyeable synthetic continuous filament yarns, false twist texturing said combined yarn to produce a torque lively yarn, overfeeding said textured yarn to a high velocity gaseous jet to convolute individual filaments in the yarn to form a plurality of torque induced kinks and winding said yarn onto a package.
Claim 3
Dependent Claim 27 words
The process of claim 1 wherein the two differently dyeable yarns are selected from the group consisting of polyester, nylon, cellulose acetate, cellulose triacetate, acrylic and modacrylic.
Claim 4
Dependent Claim 35 words
The process of claim 2 wherein the same basic fiber-forming polymer is used with modification of the polymer to provide any combination of acid dyeability, cationic dyeability, disperse dyeability, melt colored and solution colored fibers.
Claim 5
Dependent Claim 15 words
The process of claim 1 wherein at least one of the filaments is polyethylene terephthalate.
Claim 6
Dependent Claim 23 words
The process of claim 4 wherein one of the yarns is disperse dyeable polyethylene terephthalate and another yarn is cationic dyeable polyethylene terephthalate.
Claim 7
Dependent Claim 12 words
The process of claim 1 wherein three differently dyeable yarns are combined.
Claim 8
Dependent Claim 21 words
The process of claim 1 wherein the textured yarn is heat set prior to taking up the yarn onto a package.
Claim 9
Dependent Claim 27 words
The process of claim 1 wherein the differently dyeable yarns are combined in an amount ranging from 20 to 80 percent each of the total textured yarn.
Claim 10
Dependent Claim 12 words
The process of claim 1 wherein the differently dyeable yarns are co-spun.
Claim 11
Dependent Claim 25 words
The process of claim 1 wherein the yarns being combined are partially oriented yarns and the combined yarns are simultaneously drawn and false twist textured.
