Abstract

The invention discloses a preparation method of composite color-changing and temperature-adjusting fiber. A composite color-changing and energy-storing capsule is added to a fiber core layer, so that the composite color-changing and temperature-adjusting fiber has the effects of energy storage, temperature adjustment, ultraviolet protection and visual display of environmental ultraviolet intensity and temperature, the functionality of the fiber is improved, meanwhile, the fiber can show various colors under different environmental conditions, and the color changing types of the fiber are enriched. An anti-settling agent added in the preparation process of the composite color-changing and energy-storing capsule can ensure that a core material component is uniformly and stably dispersed in the capsule, so that the phenomenon that the color development capability of the capsule is reduced due to dye agglomeration after multiple times of thermal cycling is effectively avoided, and the service life of the fiber color-changing function is prolonged. The synthesis process is simple, the requirement for equipment is low, reaction conditions are easy to control, large-scale production is facilitated, and the method has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing a composite color-changing temperature-changing fiber.
