Problems solved by technology

In the first method, the method of dissolving the protein into a protein solution will completely destroy the original cavity structure of the protein fiber. If there is no subsequent cross-linking treatment, the loss of protein will be serious during spinning or post-processing; if cross-linking is used Treatment, mainly using aldehydes for acetalization or using heavy metals for denaturation and curing, not only affects the quality of protein fibers, but also causes serious environmental pollution
In the second method, nano- or micron-shaped protein powder is added. Although the problems in the first method are avoided, the protein powder will still swell in the viscose collagen solution, which will affect the filtration performance of the blend.
Among them, the preparation of hemp pulp viscose spinning stock solution is hot and full of viscose technology, which uses strong alkali and takes a long time, which greatly damages the active ingredients in hemp pulp and affects the performance.
At the same time, protein is an organic substance, and the effect of lye treatment, ceramic roller, and star ball mill for grinding and dispersing is poor, which affects the quality of protein

Abstract

The invention provides a functional cellulosic fiber with silk and linen characteristics. The functional cellulosic fiber is characterized by containing amino acid. The invention further provides a method for preparing the functional cellulosic fiber with the silk and linen characteristics. The method is characterized by comprising the step of preparation of a high-viscosity protein solution, preparation of the high-viscosity protein solution comprises the step of preparation of a urea solution, and preparation of the urea solution comprises the steps that the urea solution with the concentration of 3.0 mol / L to 6.0 mol / L is prepared and then heated to 35 DEG C to 50 DEG C. The fiber prepared through the method contains 1.12 wt%-4.96 wt% of the amino acid and 2.0 wt%-6.0 wt% of a linen extract, and therefore the prepared fiber has the more comfortable experience and the functionality.

Description

technical field [0001] The invention belongs to the chemical fiber technology in the field of textile technology, and specifically relates to a functional cellulose fiber with silk and hemp characteristics and a preparation method thereof. Background technique [0002] Due to the reduction of arable land and the depletion of oil resources, the production of natural fibers and synthetic fibers has been more and more restricted. At the same time, as people return to nature and advocate green textiles, natural protein fiber and hemp fiber fabrics are more and more valued by people. However, due to the rough texture of hemp fiber, it is not suitable to be directly used as a raw material for textiles. It needs to be processed by various processes, which increases the cost, and the output increases slowly, which cannot meet the actual demand; the output of natural protein fibers such as silk and cashmere is limited, and the price is expensive. , making it difficult for the genera...
