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

摘要

A textile sleeve (10) has wall of interlaced warp yarn (12a) and weft yarn (12b). The warp yarn (12a) extends lengthwise along a longitudinal axis of the sleeve (10) between opposite first (16) and second (18) ends of the sleeve. The warp yarn (12a) is non-metallic heat-shrinkable polymeric yarn. The sleeve (10) has at least one electro-functional member (14) interlaced with some of the weft yarn (12b). The at least one electro-functional yarn (14) extends along the longitudinal axis between the first (16) and second (18) ends. The non-metallic polymeric warp yarns (12a) have a greater heat-shrinkage ratio than the at least one electro-functional member (14). The non-metallic polymeric warp yarns (12a) are caused to be shortened in the lengthwise direction along the longitudinal axis relative to the at least one electro-functional member (14) upon being heated.
