Abstract

We offer temperature-regulating textile products with excellent heat retention capabilities, keeping you warm in winter and cool in summer. [Solution] The fabric comprises a surface fabric layer 1 containing phase-change fibers, a filling layer 2 consisting of batting containing phase-change fibers, and a back fabric layer 3 containing phase-change fibers, with these three layers integrally fixed by quilting stitching or adhesive bonding. The unit mass of the surface fabric layer and the back fabric layer is 50 to 400 g / m2, and the unit mass of the filling layer is 50 to 300 g / m2. The phase-change fibers have a phase-change temperature of 15 to 38°C and a heat storage capacity of 20 J / g or more. This provides excellent responsiveness and sustainability of heat absorption and release, and achieves a comfortable feel that is flexible, highly breathable, and less prone to stuffiness.
