ABSTRACT:
A tire warm-up wrap used for pre-heating tires of motor racing cars and motor cycles immediately before the start of a race is provided with a heat generating narrow fabric woven from a warp containing (i) an electrically heat-generating flexible yarn made of a mixed yarn composed of discontinuous conductive metal fibers and non-conductive fibers, and (ii) a non-conductive fiber yarn, and a weft composed of a non-conductive fiber yarn. The fabric has in both of the lengthwise end portions thereof wefts composed of conductive metal wires which are divided into a plurality of metal wire electrodes. The electrically heat-generating flexible yarns of the warp and the divided metal wire electrodes form together a series circuit extending forward and backward alternately along the length of the fabric between the divided metal wire electrodes in both the end portions thereof.
