Composite metal fiber electric heating cloth and uses thereof
The invention belongs to the exothermic material field, relate to a kind of composite metal fiber electric heating cloth and uses thereof.
At present, both at home and abroad at the following all kinds of metal electric heating silks that use of 300 degree because ubiquity is afraid of bending, is afraid of moist water logging, easy oxidation, defectives such as the life-span is short, dangerous, electric conversion rate is low, manufacturing process complexity, cause the scope of application limited.
The object of the present invention is to provide a kind of softness tough and tensile can be folding, rub, wash, the composite metal fiber electric heating cloth that resistance value is stable, electric conversion rate is high, safe and reliable, the scope of application is wide, the life-span is long.
The present invention evenly does the braid that parallel, general fibre are done warp at interval with each root metallic fiber and per two general fibres, and metal weaving electrode is made at its two ends, solder joint respectively is set and connects lead.
Connecting lead is the flat belt-like body of sand hill line braiding.
Be used as heating warming clothes, shoes and hats, bedding, life warming article all adopts composite metal fiber electric heating cloth as claimed in claim 1 (A) to do heater.
Advantage of the present invention is:
(1), can use for a long time below 250 ℃;
(2), this electric heating cloth quality is soft and tough and tensile, anti-folding, rub, can normally wash;
(3), resistance value is stable, has good heating uniformity and durability;
(4), electric conversion rate height, energy-saving safety, technology are simple;
(5), be fit to the following low voltage power supply power supply of 36v;
(6), good, the long service life of anti-wear performance, be partially damaged and can normally use;
(7), this electric heating cloth has good medical care effect.

Fig. 2, composite metal fiber electric heating cloth are used for the structure connection diagram of heating shoes, trousers, clothing
Be further described in conjunction with the accompanying drawings: composite metal fiber electric heating cloth A does parallel, does the braid that warp is formed by weaving with general fibre 2 (comprising cotton, fiber crops, chemical fibre etc.) with metallic fiber 1 and the even 5mm at interval of general fibre 2 (comprising cotton, fiber crops, chemical fibre etc.), make metal weaving electrode 3 at its two ends, solder joint respectively is set and connects lead 4 (referring to Fig. 1).
Connecting lead 4 is flat belt-like bodies of sand hill line braiding.
The present invention has many uses general, and every being used for done the warming clothes, shoes and hats of warming oneself, and comprises warming article on underwear, underpants, gloves, socks, shoe-pad, beauty mask, the bed, and life warming article etc. can adopt this electric heating cloth to do heater.
Embodiment 1: shown in Figure 2 is adopts composite metal fiber electric heating cloth to make heater, the annexation schematic diagram of the electric heating footwear of making (among the figure shown in the frame of broken lines I), Electrothermic trousers (among the figure shown in the frame of broken lines II), electrically-heated suit (among the figure shown in the frame of broken lines III) and power supply police platform (among the figure shown in the frame of broken lines O).
A represents composite metal fiber electric heating cloth among the figure, and on behalf of the flat belt-like of sand hill line braiding, 4 connect lead.Among the frame I A is fixed in sole and the vamp, connects, draw plug 5 by connecting lead 4; Frame II and frame III rationally distribute conductor A to be fixed in the about layer, connect by connecting lead 4, and the plug 5 of frame I joins with the jack of frame II, and the plug 5 of frame II joins with the jack of frame III and constitutes the loop.
