Method for producing temperature-regulating viscose fibers

Abstract

The invention discloses a method for producing temperature-regulating viscose fibers. The method comprises the following steps: by taking natural cellulose as a raw material, preparing soluble cellulose xanthate by virtue of processes such as alkalizing, aging and yellowing, and dissolving the cellulose xanthate in dilute alkali liquor so as to prepare the viscose, wherein aids are added in the process. According to the equipment and process improvement, the chemical reaction effect and filtering effect are improved, and the aim of improving the quality of the viscose is achieved, so that the aims of adjusting the fineness and improving the physical properties of the product are achieved; and in the process of blending phase change capsule materials, grinding and secondary micro porous filtration are performed. The phase change capsule material is added before spinning and is mixed with the viscose solution to be uniform; and meanwhile, when the viscose fiber is positioned in a macromolecular amorphous form and passes through a low-diameter spinning round hole, proper draft degree and forming process conditions are selected, and the aim of adjusting the fineness of the fibers is achieved. The produced temperature-regulating viscose fibers are low in fineness, high in strength and high in caloric content value and have good bidirectional temperature regulating functions; and the product has the characteristics of moisture absorption and discharge capacities, breathability, sunlight resistance, moth-eaten resistance, anti-static property and simplicity in spinning.

Description

Technical field [0001] The present invention involves a method of temperature -regulated sticky glue fiber. Background technique [0002] With the continuous improvement of people's consumption level, people's functional demand for textile supplies is also increasing.Functional textiles are also increasingly winning the favor of consumers. [0003] Temperature -tone adhesive fiber is a new type of sticky fiber differentiated product.It is based on natural cellulose, which is made through equipment improvement and under specific processes, through the process of alkaliization, aging, and yellowing to make soluble cellulose cloakacide, and then dissolved in dilute alkali liquid to make sticky glue. Add it to joinPhase variable materials, functional differentiation sticky glue fibers made by wet spinning. [0004] It has all conventional properties of adhesive fiber, with a gentle and comfortable feel, strong moisture absorption, breathability, sunlight resistance, insect resistance...
