THERMALLY INSULATING TEXTILE

摘要

A thermally insulating textile (2) adapted to provide a variable degree of thermal insulation dependent on ambient temperature, the textile including a laminate of two fabric layers (15, 15') having interposed a bulking layer (1), which may be one or more fabric layers (3a, 3b) on to which is deposited a shape memory polymer (4) in a repeat pattern. The bulking layer (1) is adapted to cooperate with the fabric layers (15, 15') to vary the gap therebetween upon departure in a desired direction of the textile temperature from a predetermined temperature.
