We attempted to develop novel and comfort leisure winter sports wear such as ski wear or snow board wear that could enjoy going for the winter sports in the coldest part of the winter. This novel and comfort leisure winter sports wear was equipped with textile fabric heater which was plain stitch fabric formed by polyamide 66 filament coated silver and polyethylene terephthalate yarn. We have examined about the electric resistance change of textile fabric heater under tensile strain until breaking point and the electric resistance change in case of applying concentrated compression load on textile fabric heater. Experiments were carried out to evaluate heating performance of textile fabric heater under a below-zero temperature and low temperature conditions. And, we designed prototype for comfort leisure ski wear. Experiments using prototype ski wear under a below-zero temperature confirmed that the temperatures in wear obtained from both cloth and pants indicated appropriate condition. It was also confirmed that the equipment method of textile fabric heater and attached points for human 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 by examinees including to the persons of advanced age from elementary school children.
We are going to complete comfort leisure winter sports wear equipped with textile fabric heater consulting examinees about the problem and/or improvement points.
