HYBRID FABRICS FOR EXTREME WEAR INDUSTRIAL AND APPAREL APPLICATIONS
First Claim
1. A twisted, non-blended yarn comprising a twisted combination of one or more polyolefin fibers and one or more non-polyolefin fibers, wherein the twisted yarn has a yarn surface area, wherein said polyolefin fibers form greater than 20% of said yarn surface area, and wherein said polyolefin fibers and said non-polyolefin fibers are twisted together.

Abstract
Twisted, non-blended hybrid yarns are provided that are suitable for the fabrication of abrasion resistant garments and other textile articles. One or more polyolefin fibers are ply twisted together with one or more non-polyolefin fibers in a manner that utilizes the properties of each fiber type. A plurality of the twisted, non-blended hybrid yarns is then woven or knitted into fabrics, such as twill woven denim, or formed into ropes, such as braided ropes.

20. A process for producing a twisted, non-blended yarn, comprising:
-
a) providing one or more polyolefin fibers; b) providing one or more non-polyolefin fibers, wherein said non-polyolefin fibers comprise one or more synthetic fibers, one or more natural fibers, or both one or more synthetic fibers and one or more natural fibers; c) laying said polyolefin fibers and said non-polyolefin fibers side-by-side in parallel to thereby form a non-blended, untwisted fiber bundle wherein the untwisted fiber bundle has a surface area, and wherein said polyolefin fibers form greater than 20% of said fiber bundle surface area; and d) twisting said non-blended fiber bundle to form a twisted yarn, wherein said polyolefin fibers and said non-polyolefin fibers are twisted together at a 1;
1 ratio relative to each other, wherein the twisted yarn has a yarn surface area and wherein said polyolefin fibers form greater than 20% of said twisted yarn surface area.
