Abstract
A process for producing fancy woven fabrics having balanced hand characteristics on each of the face and back is described. The process involves hydraulically processing a fancy-woven fabric having spun yarns in the warp to force fibers from spun yarns which are dominant on one fabric surface through the fabric to regions to form a nap on the other surface of the fabric. The process achieves fabrics having balanced hand characteristics with superior strength to those formed by conventional napping and sanding processes. In addition, the patterns have good pattern clarity.
Claims36
A fabric comprising:
- a plurality of spun warp yarns interwoven with a plurality of filament filling yarns in a fancy weave construction, said fabric having Kawabata System MIU values for each of fabric face and back of greater than 0.23, and a difference in SMD surface roughness between the face and back of the fabric of less than 1.5.
A method of making fancy woven fabrics having superior aesthetic characteristics comprising the steps of:
- providing a fancy woven fabric having spun warp yarns and filament filling yarns;
- hydraulically treating the fabric so as to form a nap on portions of said fancy woven fabric where the filament filling yarns are predominant.
A napped fancy woven fabric having filament yarns in the filling, wherein the surface hand of the face of the fabric is approximately equal to the surface hand of the back of the fabric.
A method for improving the hand of a fancy woven fabric having spun yarns in the warp and filament yarns in the filling comprising the step of:
- hydraulically treating the fabric to push fiber loops from said spun yarns over said filament yarns, to thereby provide a nap on said filament yarns without significantly reducing the strength of the fabric.
