Thermosensitive clothes material with temperature adjusting function and preparation method thereof.

Abstract

The invention relates to a thermosensitive clothes material with temperature adjusting function and a preparation method thereof. A circuit layer which is prepared based on PTC (positive temperature coefficient) effect is applied to the thermosensitive material, so that the thermosensitive material has the temperature adjusting function; at the same time, a minisize pressure sensor is arranged in the circuit layer for detecting side pressure caused by a thermal resistance which expands due to heating, and the minisize pressure sensor outputs control signals and actively reduces the voltage which is applied to the thermal resistance. According to the arrangement, energy of power supply is better utilized, and environmental protection and energy consumption reduction are realized.

Description

technical field [0001] The invention relates to the field of heat-sensitive clothing materials, in particular to a heat-sensitive clothing material with the function of regulating body temperature and a preparation method thereof. Background technique [0002] By using heat-generating cloth or placing heat-generating sheets in clothing, thereby increasing the heat-retaining capacity of clothing and achieving the effect of resisting cold, it has been widely used in the prior art. The most typical one is the warm baby that is common in life, which has the advantages of convenient use, low price, and sufficient heat generation. However, baby warmers may generate too much heat, and they are disposable items, so discarding them after use will pollute the environment. [0003] In the prior art, heating fabrics or heating sheets that generate heat through electricity are also used. In this way, the heating fabrics or heating sheets can be reused. However, since the circuit is base...

AI Technical Summary

Problems solved by technology

[0005] However, although the PTC thermosensitive material limits the excessive heating of the material and regulates the body temperature, it causes a certain amount of energy waste due to the increase in the resistance value of the material during the working process.

At the same time, since it is usually necessary to use small-sized portable batteries to heat clothing, the resulting energy waste will accelerate battery consumption, resulting in frequent replacement of batteries, which is not conducive to environmental protection and energy saving.
