Heatable and flexible textile sheet for manufacturing e.g. heatable mattress pad, has heating layer combined with damp-proof barrier layer, which has heating element with combination yarn that has conductive thread wound over core thread

摘要

#CMT# #/CMT# The textile sheet has a heating layer (1) in which heating element (2) is provided. The heating element comprises electrically conductive combination yarn which includes core thread (3) and electrically conductive thread (4) wound over the core thread. A moisture-control or damp-proof barrier layer is formed parallel to the heating layer and combined with the heating layer. The electrically conductive thread comprises monofilament wire or strand made of stainless steel. #CMT#USE : #/CMT# Heatable and flexible textile sheet for manufacturing heatable mattress pad, electric blanket, heatable pad, heatable bed covering, heatable curtain, electrically heatable clothing such as jacket, trousers, shirt, T-shirt, sports garment, undergarment, socks or gloves, and electrically heatable car seat (all claimed). #CMT#ADVANTAGE : #/CMT# Highly flexible and durable textile sheet can be obtained while attaining reliable heating operation. The transcutaneous electrical nerve stimulation (TENS) can be suppressed and the unpleasant tingling sensation on the skin of user can be avoided. The mutually-separated leads are extended with respect to the heating element such that uniform heating can be facilitated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a photographic view of the heating layer of the textile sheet. 1 : Heating layer 2 : Heating element 3 : Core thread 4 : Electrically conductive thread 6 : Electrically non-conductive thread #CMT#POLYMERS : #/CMT# The core thread is made of elastomeric fiber such as Lycra(RTM: a type of stretch fiber).
