Abstract

The invention provides a warm feeling enhancing fabric and a preparation method thereof. The warm feeling enhancing fabric comprises a heating layer, a heat conduction and heat storage layer and a thermal insulation layer. The heating layer is a fabric finished by a warm feeling and moisture retention composite finishing agent, the heat conduction and heat storage layer is a high heat conduction phase change microcapsule coating, and the thermal insulation layer is an aerogel foaming coating. According to the preparation method, efficient heat management of the fabric can be realized through cooperation of heating, heat conduction, heat storage and heat insulation effects among all layers, so that the warm feeling effect is remarkably enhanced; and meanwhile, moisturizing factors are added into the fabric, so that dryness and discomfort of the skin are relieved in winter, and the skin can be kept moist.

Description

technical field [0001] The invention belongs to the field of textile processing, and in particular relates to a method for preparing fabrics with enhanced warmth. Background technique [0002] Year after year of severe winters and fast-paced lifestyles have made people demand "light weight and warmth" for warm fabrics. At present, warm fabrics on the market are mainly divided into two categories: positive warm fabrics such as electric energy / chemical energy / solar heating fabrics, moisture-absorbing heat-generating fabrics, and phase change thermal storage fabrics, and negative warm fabrics such as laminated / high-density / low thermal conductivity fabrics / Far infrared fabric etc. Among them, airgel is considered to be a good lightweight thermal insulation material because of its extremely high porosity and extremely low bulk density, but it is easy to cause heat loss due to its low thermal conductivity and poor air permeability, which make the human body unable to effectively...
