Abstract
Abstract Disclosed herein are woven, knitted or braided fabric coverings having an increased abrasive resistance under vibrating conditions which are suitable for hoses, wires, tubes, harnessing, etc. where vibration under abrasive conditions causes rapid wearing of protective coverings. The resistance to these conditions is achieved by incorporating into the fabric of a flexible first yarn, a second yarn of a metal wire filament of comparable flexibility as the first yarn and forming a matrix to protect the first yarn. Also disclosed is the method of making the protective coverings from these fabrics.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
151 words
A flexible fabric sleeve type covering suitable for protecting and covering of products used under abrasive and vibrating conditions, which comprises: a first yarn of a flexible strand of a material selected from the group consisting of ceramic, quartz, glass, and engineering plastic polymer, and mixtures thereof, a second yarn of a flexible strand of a metallic wire selected from the group comprising stainless steel, black iron, inconel and copper, the number of strands of second yarn are from two (2) to twenty-five (25) percent of the total number of strands of both yarns, the second yarn having a diameter of about 3 to 8 mils, and said sleeve type covering having a flexibility substantially equal to the flexibility of a sleeve type covering made from only the first yarn, the second yarn being equally distributed throughout the covering in a matrix which protects the first yarn under abrasive, vibrating conditions.
Claim 2
Dependent Claim
