Color change cellulose fiber preparation method

Abstract

The invention provides a color change cellulose fiber preparation method which includes the steps: color change microcapsule sizing agent preparation; ultraviolet absorbent sizing agent preparation; spinning. Fibers prepared by the method have temperature sensing color change and night light effects, fiber colors are changed along with change of environment temperature, and the fibers can emit light at night or in dark environments. According to the method, color change materials and luminous materials are coated by a microcapsule method to prepare sizing agents, and the sizing agents are uniform, cannot be layered and are suitable for being added into cellulose solution to perform spinning. Rare-earth luminous materials are of pore structures, the color change materials and the luminous materials can be more closely and integrally combined in microcapsules and more easily coated, and performances are more stable. According to the method, inorganic ultraviolet absorbents are added intothe fibers, chemical properties are stable, easily light decomposed color change materials can be protected, color change durability of the cellulose fibers is improved, and the cellulose fibers havesun-screening effects.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of cellulose fibers with a color-changing function. Background technique [0002] The color-changing fiber is a textile prepared by using the unique structure and performance of the color-changing material. The color of the fiber can show a dynamic change effect with the change of external conditions, giving the textile a dynamic visual impact and catering to people's pursuit of newness and individuality in textiles. The consumption psychology of modernization and functionalization has made textiles have a new development in the application of clothing, military, and temperature indicators. [0003] At present, there are mainly three types of temperature-sensitive color-changing materials: inorganic, crystalline, and organic. Inorganic color-changing materials are highly toxic and have low sensitivity, so they are not suitable for direct use on ...

Problems solved by technology

[0011] (1) Pure temperature-sensitive color-changing materials can only change color in an environment with light and temperature changes, and will not actively emit light in a dark environment. At present, color-changing materials that can not only change temperature but also emit light in a dark environment The material is not suitable for adding directly to the wet spinning solution;

[0012] (2) The temperature-sensitive color-changing material has poor stability, and the color-changing effect is not long-lasting
