Problems solved by technology

At present, there are three main researches on heat-retaining fabrics: (1) Heat-retaining fabrics based on some special fibers that absorb heat and heat. The kinetic energy is reduced and converted into heat energy release at the same time to achieve the purpose of moisture absorption and heat generation. However, due to the high peak temperature rise and disordered heat production in this method, it is easy to cause low-temperature burns; Add special substances to absorb solar energy and convert it into heat energy, and emit far infrared rays at the same time to achieve the purpose of heating, but the performance of this method is greatly affected by weather changes, and its heating efficiency is very low in the case of weak sunlight , and is limited to outdoors. In addition, the materials used in this method are expensive and the production cost is high; (3) Heat-generating fabrics based on phase change heat storage. The form absorbs, stores and releases heat, so as to achieve the purpose of heat absorption and heat generation, but this method is not washable, and there is a leakage problem of solid-liquid phase transition

Abstract

The invention discloses a method for preparing a spontaneous heating fabric. The method comprises the following processes: weaving, pretreatment, softening finishing, drying, heat setting, spontaneousheating wax therapy healthcare finishing, and heating drip feeding for obtaining the finished product. The spontaneous heating wax therapy healthcare finishing process comprises the following steps:mixing tourmaline stone powder, far-infrared ceramic powder, beeswax and paraffin according to a mass ratio of (10-30):(5-20):(10-30):(10-30), heating the obtained mixture to 70-90 DEG C, carrying outhigh-speed stirring and uniform mixing to obtain a spontaneous heating wax therapy mixed solution, dripping the mixed solution on the surface of a heat-set fabric, and carrying out normal temperaturecooling solidification to obtain spontaneous heating wax therapy healthcare particles; and the heating drip feeding process comprises the following steps: uniformly mixing an elastic polyurethane crystal glue A with an elastic polyurethane crystal B, vacuumizing the obtained mixture, drip-molding the mixture on the surface of the spontaneous heating wax therapy healthcare particles, and drying and solidifying the spontaneous heating fabric. The method effectively avoids low temperature burns of skins, eliminates the influences of weather change on the performances of the fabrics, makes the fabric have a wax therapy healthcare effect, and improves the washing resistance of the functional fabric.
