Problems solved by technology

The intelligent temperature-regulating textile of this invention is to embed the phase change material into the gel of the three-dimensional network structure of silica with high thermal conductivity to make a composite phase change material from nanometer to micron scale, and then coat the composite phase change material It is made of cloth on the surface of textile fabrics, which uses the network structure of gel to inhibit the precipitation of liquid phase change materials during the phase change process, so that it will not cause negative effects similar to oil immersion on the appearance of textiles, and the composite phase change The performance of the material is stable and has a high phase change enthalpy and a suitable temperature adjustment range; however, the composite phase change material is mixed with the adhesive and coated on the surface of the textile fabric by the coating method, so that the textile fabric The air permeability of the surface is poor, resulting in poor comfort performance of the fabric, and the combination of the phase change material and the fabric is not strong, the washability of the fabric is also poor, and the temperature adjustment function of the fabric will also decline after a period of time
