Heating component of warming product, preparation method and application of heating component

Abstract

The invention discloses a heating component of a warming product, a preparation method and application of the heating component. According to the preparation method, nanometer stainless steel filaments, a thermal adhesive sealant, low-denier chemical fiber cloth and a thermal insulation material are adopted to prepare the heating component of the warming product. The method has the advantages of simple and reasonable process steps, convenient operation, easiness in realization of industrial automation, high efficiency and obvious economic benefits. The heating component of the warming productprepared by using the method has the advantages of full-sealing structure, slimness, softness, lightness, washability, high flexibility, anti-fatigue performance, high durability, direct and uniform heat conduction, high safety, wide application range and the like. After the heating component is heated, heat can be blocked by a thermal insulation layer from being transferred to the outside, and therefore, more heat can be transferred to the interior of the component, and the effectiveness of heat energy utilization can be improved; extra heat energy can be provided in a low temperature environment, and therefore, comfort can be increased in a cold environment with the body temperature of a user ensured; and the heating component can be widely applied to warming products such as clothes, beddings, shoes, gloves and socks.

Description

technical field [0001] The invention belongs to the field of heat preservation products, and more specifically relates to a heating element of heat preservation products and its preparation method and application. Background technique [0002] Traditional thermal products usually use woven or knitted fabrics as the surface and inner layers, and silk cotton, space cotton and cotton as the middle core layer. However, since the polyester cotton core layer is made of all chemical fiber material, the air permeability and moisture permeability are poor, the filling volume is bloated and unsightly, and the thermal performance is not very good; while the cotton core layer is easy to knot and deform, and the shape is thick and inconvenient to wash. , and the mode of action of these traditional heat preservation products is only passive heat preservation, cannot actively heat, and the heating effect is not ideal. With the continuous improvement of large-capacity battery technology an...

AI Technical Summary

Problems solved by technology

However, the heating elements in these products have many shortcomings and deficiencies.

Existing heating elements usually use low-cost carbon fiber as the heating component. Due to the physical characteristics of carbon fiber, when it is used for a long time, its cycle shrinks and heats up severely, which affects the durability of carbon fiber and also affects the change of its resistance value, resulting in Unstable power and drain rate

In addition, the coverage area of ​​the heating element in the prior art is small, which directly affects the temperature sensing, and it does not have a fully sealed structure, which is heavy and cannot be washed.
