The heat preservation is a matter which is considered by human beings in winter, so that the fabric has the heat preservation performance and is an important direction for the research of the textile industry, and the traditional heat preservation fabric improves the heat preservation performance by increasing the thickness of a filler or the fabric. Therefore, the manufactured product is heavy and has poor comfort. At present, the research and development of the heat preservation performance of the fabric are limited, and the better heat preservation function cannot be achieved. In the prior art, a plurality of methods for keeping warm by a multi-layer fabric compounding mode exist, but the process flow is complex and the cost is high. The warmth retention property is improved by designing a fabric structure, but the weaving process is complicated.
In addition, most of the existing thermal fabric coating agents are solvent-based, and cannot meet the requirement of environmental protection. At present, the warm-keeping effect of the fabric coating is not ideal. Chinese patent application No. 201410023723.3 discloses a multilayer structure heat preservation coating fabric, and chinese patent application No. CN201610655683.3 discloses a heat preservation fabric with excellent heat insulation effect, but all have the problems of high cost, complex process flow, limited heat preservation effect, poor comfort performance and the like.
