FLEXIBLE THERMOSENSITIVE WIRE

A flexible thermosensitive wire which comprises a core strand, a pair of electrodes one of which is spirally wound around the core strand, a thermosensitive polymer layer formed between the paired electrodes, a barrier layer for a dry-cleaning solvent formed around the thermosensitive polymer layer having the other electrode spirally wound therearound, and an outermost moisture-permeable layer. The wire is adapted for use in electric warming devices in which because of the quick moisture release of the wire, a normal thermosensitive characteristic is quickly shown in practical applications. The electric warming devices can be dry cleaned without deterioration of the wire.
