HEAT-SHRUNK TEXTILE SLEEVE WITH EXTENDED ELECTRO-FUNCTIONAL YARN AND METHOD OF CONSTRUCTION THEREOF

摘要

A textile sleeve has wall of interlaced warp yarn and weft yarn. The warp yarn extends lengthwise along a longitudinal axis of the sleeve between opposite first and second ends of the sleeve. The warp yarn is non-metallic heat-shrinkable polymeric yarn. The sleeve has at least one electro-functional member interlaced with some of the weft yarn. The at least one electro-functional yarn extends along the longitudinal axis between the first and second ends. The non-metallic polymeric warp yarns have a greater heat-shrinkage ratio than the at least one electro-functional member. The non-metallic polymeric warp yarns are caused to be shortened in the lengthwise direction along the longitudinal axis relative to the at least one electro-functional member upon being heated.

1. A textile sleeve, comprising:
a wall of interlaced warp yarn and weft yarn, said warp yarn extending lengthwise along a longitudinal axis of the sleeve between opposite first and second ends of the sleeve, said warp yarn being non-metallic polymeric yarn warp yarn; at least one electro-functional member interlaced with some of said weft yarn, said at least one electro-functional yarn extends along said longitudinal axis between said first and second ends; and wherein said non-metallic polymeric warp yarns have a greater heat-shrinkage ratio than said at least one electro-functional member causing said non-metallic polymeric warp yarns to be shortened in the lengthwise direction along said longitudinal axis relative to said at least one electro-functional member upon being heated.
