Abstract

The invention provides a preparation method of fibroin / temperature-sensitive cellulose fabric. The preparation method comprises the following steps: S1, preparing oxidized cellulose; S2, preparing a fibroin aqueous solution; S3, preparing fibroin / cellulose composite porous microspheres; S4, preparing a phase change material; S5, preparing a composite phase change material; and S6, preparing the temperature-sensitive fabric. According to the fibroin / temperature-sensitive cellulose fabric provided by the invention, fibroin / cellulose microspheres loaded with a phase-change material are finished on the fabric, so that the temperature of the fabric is intelligently controlled under a certain temperature condition.

Description

technical field [0001] The invention relates to functional fabrics, in particular to a preparation method of silk fibroin / cellulose temperature-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 real...
