Manufacturing method of composite heating sheet for heating clothes

Abstract

The invention provides a composite heating sheet for heating clothes. The composite heating sheet comprises a plurality of resistance wire bundles, clamping sheets, conducting wires and a power source, wherein the plurality of resistance wire bundles are connected in series or in parallel or in series-parallel to form a resistance unit for electrifying and heat release, the resistance unit has a positive electrode and a negative electrode, at least two clamping sheets are arranged, the resistor unit is wrapped between the two clamping sheets, the clamping sheets are used for clamping and fixing the position of the resistor unit, the two conducting wires are electrically connected with the positive electrode and the negative electrode of the resistor unit respectively, an external power supply is electrically connected with the positive electrodes and the negative electrodes of the resistor units through the conducting wires, adjacent conductive wire bundles are wound in a crossed or staggered manner to form a mesh structure arranged in an array, and the plurality of resistance wire bundles are arranged to be wound into a horizontal-8-shaped or #-shaped mesh structure to form a resist unit, so that a heating series-parallel circuit is formed, the total resistance is small, and the application requirement of low voltage can be met. According to the invention, the circuit structure has a good heating effect and can maintain a uniform and stable temperature range.

Description

technical field [0001] The invention relates to the technical field of clothing heating sheets, in particular to a method for manufacturing a composite heating sheet for heating clothing. Background technique [0002] Traditional thermal clothing uses still air between fibers to block heat loss and passively keep warm from cold. After a period of use, the thermal performance of such clothing will decrease due to changes in the air layer. Therefore, active heating clothing has a greater effect on keeping warm from the cold, and is especially suitable for workers in certain cold areas (such as soldiers stationed in high-altitude areas, mountaineers and staff in polar research stations, etc.). It provides a new concept and approach for the development and design of new heating clothing. [0003] In the field of textile and clothing, how to reduce the modulus of carbon fiber tow and make it Softness, while ensuring its good conductive and heating properties, is the key to impr...
