Abstract
This invention provides a braided tubular sleeve having increased abrasion resistance. The braided tubular sleeve according to this invention have a resilient self-conforming "springback" property which enables the sleeve to conform in close contact with the surface of substrates, such as wire or cable bundles. The increased abrasion resistance is provided by braiding in with the resilient plastic yarns about one to about twenty ends of a resilient monofilament yarn such as nylon for every two ends of a resilient engineering plastic monofilament yarn such as polyester.
Claims7
A braided tubular abrasion resistant sleeve comprising a resilient monofilament yarn and an abrasion resistant monofilament yarn present in a ratio from about one end of resilient yarn to two ends of abrasion resistant yarn and up to about ten ends of resilient yarn to one end of an abrasion resistant yarn wherein the resilient yarn comprises an engineering plastic having a tensile modulus of at least 100,000 and the abrasion resistant yarn comprises a polymeric material having a tensile modulus at least 50,000 less than the modulus of the resilient yarn, wherein the abrasion resistant yarn is larger diameter than the resilient yarn.
