ABSTRACT

　We attempted to develop novel and comfort leisure winter sports wear such as skiwear or snow board wear that could enjoy going for the winter sports in the coldestpart of the winter. This novel and comfort leisure winter sports wear was equipped withtextile fabric heater which was plain stitch fabric formed by polyamide 66 filamentcoated silver and polyethylene terephthalate yarn. We have examined about the electricresistance change of textile fabric heater under tensile strain until breaking point andthe electric resistance change in case of applying concentrated compression load ontextile fabric heater. Experiments were carried out to evaluate heating performance oftextile fabric heater under a below-zero temperature and low temperature conditions.And, we designed prototype for comfort leisure ski wear. Experiments using prototypeski wear under a below-zero temperature confirmed that the temperatures in wearobtained from both cloth and pants indicated appropriate condition. It was alsoconfirmed that the equipment method of textile fabric heater and attached points forhuman body was a rational procedure from experimental results. In this winter season,we make a plan practical test using ski wear equipped with textile fabric heater byexaminees including to the persons of advanced age from elementary school children.We are going to complete comfort leisure winter sports wear equipped with textilefabric heater consulting examinees about the problem and/or improvement points.
