Embodiment Construction

[0029] 1. Fabrication of carbon conductive yarn

[0030] Put the carbon sensitive material with a viscosity of 100-500mpa.s and a solid content of 5-70% in a stainless steel container, stir well and evenly, and use the padding process to process the yarn without impurities, moisture, and non-sizing The strands and blended yarns are immersed in stainless steel containers, soaked, and then passed through the rolls to squeeze liquid (rolled liquid rate 70%), and then dried at a temperature of 110-130°C for 90 seconds, and then baked at a temperature of 140-180°C. ℃, time 60 ~ 90s. Yarn or ply, blended yarn can be cotton, hemp, or hemp-cotton and cotton-polyester blended yarn, and the yarn count is 7-21s.

[0031] 2. Fabrication of carbon conductive fabric

[0032] Such as figure 1 As shown, the weaving method is used to weave a fabric containing conductive filaments 1 and carbon conductive yarns 3 or blended yarns, that is, carbon conductive fabrics. The warp yarns 2 in the f...

Abstract

The invention relates to a multi-purpose carbon cushion and method for producing the same. The cushion is divided into an inner mat and an outer packaging, wherein, the inner mat includes carbon heating pieces, connecting wires, and intelligent polymer lithium batteries. The carbon heating pieces are formed by pressing an environmental-protecting type polyurethane or vinyl acetate film on the carbon conductive fabrics, and a nano-bamboo carbon knitting fabric is adopted to tailor and package; radial direction conductive filaments in the carbon heating piece adopt a paralleled connection mode,and then are connected to the anode and cathode of the polymer lithium batteries; and the outer layer packages of the carbon heating cushion is made of textiles into a bag shape. The present invention is an ideal heat supply and thermal protection cushion, which has advantages of fast heating up, tasteless, pollution-free, and widely application to legs, shoulders, stomach, waist, abdomen, etc.

Description

technical field [0001] The invention relates to a cushion and a preparation method thereof, in particular to a multipurpose carbon heating cushion and a preparation method thereof. Background technique [0002] Commonly used cushion products have various shapes such as seat cushions, back cushions, sofa cushions, square cushions, round cushions, and rectangular cushions. Most of them are made of textile materials and have no heating function. There are also various pad products made of heating conductive wires, but the heating effect is uneven, and the 220V voltage is used for power supply, so there are safety problems. [0003] In order to overcome the above problems, the present invention uses self-developed carbon yarns to make conductive fabrics, uses thin environmental protection materials for composite packaging, and uses low-voltage polymer lithium batteries for power supply, with fast electrothermal conversion, uniform heating, and soft materials. Good security. C...
