Embodiment 1

[0024] The schematic diagram of the structure of the heatable cloth is shown in figure 1 As shown, it includes a cloth layer 1 and two flexible substrate layers 2-1, 2-2. On the flexible substrate layer 2-1, a heating thick film circuit 4 is printed and burned at a high temperature, and the heating thick film circuit 4 is arranged between the flexible substrate layers 2-1 and 2-2 in a folded manner. The flexible base material layer is bonded to the cloth layer 1 through an adhesive layer 3; the contact point for connecting the external power supply is a riveting joint, including riveting nails 51 and conductive mesons 53, and the flexible base material layer has perforations 52, 54, The riveting nail 51 passes through the conductive meson 53 and the perforations 52 and 54 , and presses and connects the conductive meson 53 and the heating thick film circuit 4 . The other side of the cloth layer 1 is also provided with a heat reflection layer 6 made of tinfoil, heat emission co...

Abstract

The invention provides a heating fabric based on a flexible thick-film heater and a temperature control method thereof. The heating fabric comprises a fabric layer and at least one flexible base material layer, wherein a heating thick-film circuit is sintered on one of the flexible base material layers and arranged on the flexible base material layers in a folding-back or tiling manner; the flexible base material layers are bonded with the fabric layer through a bonding layer, and the heating thick-film circuit is between the flexible base material layers and the fabric layer; the flexible base material layers are made from a relatively thin polyester/polyimide/polyether imide material; the bonding layers are made from a hot-press bonding material; and a thick-film temperature control circuit with the PTC effect is arranged around the track of the heating thick-film circuit and connected with a temperature control device, and the temperature control device controls power output to the heating thick-film circuit through examining resistance changes of the thick-film temperature control circuit. According to the heating fabric, temperature control in different temperature stages can be realized through the PTC effect of the thick-film temperature control circuit, so that power output in different stages can be carried out.

Description

technical field [0001] The invention relates to the application field of flexible thick-film circuit heating, specifically combining a flexible thick-film heating circuit with clothing fabrics to produce a fabric that can generate heat and keep warm. The invention also includes a method for controlling the temperature of the exothermic cloth. Background technique [0002] In order to increase the effect of heat preservation and cold protection, there is a technical solution in the prior art that heating elements are put into clothing to make heatable and heat-insulating clothing. [0003] For example, the common warming patch (warm baby) is based on the principle of converting chemical energy into heat energy. The cloth patch coated with chemical materials is added to the clothing to generate heat. It has a long heating time (can be heated at 130cm 2 , 50-60 degrees for 10-12 hours), cheap and other advantages, but it also has the disadvantages of uncontrollable temperature...
