Abstract

The invention provides a preparation method of a temperature-sensitive fabric. The preparation method comprises the following steps of S1, preparing an adsorption material; S2, preparing a phase change material; S3, preparing a composite phase change material; S4, coating and shaping the composite phase change material; S5, modifying the composite shaped phase change material; and S6, grafting a polyester fabric to the modified composite shaped phase-change material. Chitosan is creatively selected as a phase-change carrier material, ethyl cellulose is used for recovery after the phase-changematerial is added, the phase-change carrier material which can be dissolved but not molten in chitosan finishing is obtained, and after chitosan finishing, the hand feeling of the fabric maintains thehand feeling of an original unfinished fabric and is even superior to the original hand feeling.

Description

technical field [0001] The invention relates to functional fabrics, in particular to a method for preparing warm-sensitive fabrics. Background technique [0002] When the environment of the human body changes, heat transfer will occur. When the normal function of the human body cannot maintain the heat balance, the human body will feel uncomfortable. At this time, clothing needs to be adjusted to ensure the heat balance in the microclimate zone. Phase-change temperature-regulating materials have gradually been applied in the field of textile and clothing because they can absorb or release heat through phase change when the ambient temperature changes. Through years of development, the development of new phase-change temperature-regulating materials has achieved some research results. However, phase-change materials cannot be directly added to clothing materials to achieve temperature-regulating functions. Some special methods are needed to realize phase-change temperature-re...
