Abstract

The invention discloses a polyurethane resin impregnation solution for intelligent temperature-regulating clothing, a superfiber base cloth and a preparation method. On the one hand, the phase change material microcapsule material used is spherical and well-coated. The internal phase change material is not easy to leak and will not corrode the microfiber substrate. On the other hand, the phase change material microcapsule material can be completely dispersed and evenly wrapped in the substrate. The inside of the cloth, and the present invention does not have potential harm no matter in the base cloth production process or in the process of people's use. At the same time, the purpose of adding calcium carbonate is to increase the weight and improve the sag feeling on the one hand, and on the other hand to affect the state of the polyurethane in the solidification process, so that the polyurethane can form a microporous structure when forming a film and increase the air and moisture permeability. The microfiber base cloth for intelligent temperature-regulating clothing prepared by the present invention has a thickness of 0.8-1.0mm, and the specific thickness can be determined according to customer requirements. Used in clothing, gloves, shoe materials and other fields.

Description

technical field [0001] The invention relates to the technical field of microfiber synthetic leather, in particular to a polyurethane resin impregnation solution for intelligent temperature-regulating clothing, a superfiber base cloth and a preparation method. Background technique [0002] With the rapid development of social economy and the improvement of people's quality of life and consumption level, the requirements for microfiber synthetic leather are getting higher and higher, requiring "healthy, comfortable and practical". This new type of superfiber that meets people's requirements Synthetic leather has become a hot spot in the leather industry, especially the research and development of intelligent temperature-regulating microfiber leather. The role of "device" to buffer changes in the external environment. [0003] Scientific research shows that when in heat balance, the most comfortable skin temperature felt by the human body is 33.4°C. The temperature of the lea...
