Problems solved by technology

However, pure chitin fiber lacks the physical and mechanical properties required for post-textile processing, and the cost is high, expensive, and its popularization and application are limited.
Composite fibers with excellent performance can be produced by blending with other materials, but it is difficult to blend and make rubber. How to solve the problem of blending chitin with other materials has become a technical problem that has been difficult to solve for a long time

Abstract

The invention relates to a glue preparation method by dissolving chitin and vinylon fibers with an ionic liquid, which comprises the following steps: adding crushed chitin and polyvinyl butyral into a container filled with the ionic liquid, stirring and dissolving under the condition of 120 DEG C oil bath until a transparent glue solution is formed, the concentration of the transparent glue solution is 5-25%, and the transparent glue solution is free from layering and impurities; then carrying out vacuum defoaming in an environment of-0.95 MPa to obtain a spinning glue solution; vinylon and chitin can be dissolved in the same ionic liquid at the same time, the problem of blending of chitin and vinylon for glue preparation is well solved, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of spinning engineering, in particular to a glue-making method for dissolving chitin and vinylon fibers in an ionic liquid. Background technique [0002] Chitin is a linear polysaccharide biopolymer that widely exists in the shells of insects, aquatic crustaceans and the cell walls of seaweeds, such as crabs, shrimps, gong fish bones, egg shells, bee bees, fungi, etc. The amount is second only to plant fibers. Chitosan, also known as chitosan, has unsaturated cationic groups in its molecular structure, so it has a strong adsorption effect on all kinds of negatively charged harmful substances and harmful bacteria, so that it can absorb harmful bacteria. The activity is inhibited, making it inactive, so as to achieve the purpose of antibacterial. It not only has a structure similar to plant fiber, but also has a structure similar to that of human bone collagen. It has good compatibility with the human body a...
