Spinning material capable of being quickly dissolved or dispersed and preparation method and application thereof

Abstract

The invention provides a rapidly dissolving or dispersing spinning material and its preparation method and application. Ethanol and water are used as neutral base solvents, a small amount of citric acid or lactic acid is used as a crosslinking agent, and glycerin is used as a crosslinking accelerator. , using the electrospinning method to process hot-melt natural macromolecular colloidal substances or pure natural macromolecular extracts or compound substances into silk threads, and weave the silk threads into various shapes that are convenient for packaging, storage and carrying. According to the melt viscosity, toughness and dispersion characteristics of the substance, it is processed into filaments of different diameters, so as to realize rapid dissolution or dispersion in the water phase or oil phase, and achieve the effect of instant dissolution in water.

Description

technical field [0001] The invention belongs to the field of health care products and skin care products, and in particular relates to a rapidly dissolving or dispersing spinning material and its preparation method and application. Background technique [0002] Hot-melt natural macromolecular colloids or pure natural macromolecular extracts, such as collagen, donkey-hide gelatin, propolis, isinglass, peach gum, bird's nest, etc., are widely used in food, beverages, cosmetics, health care products and medical treatment . Its many functions, such as nourishing blood, stopping bleeding, nourishing yin, nourishing qi, moistening dryness, moistening lungs and beautifying skin, relieving cough and asthma, repairing wounds, removing wrinkles, removing freckles, and improving immunity, have received more and more attention. The acquisition, pretreatment, finished product and use of these products are relatively complicated processes, and even more professional technical capabilitie...

AI Technical Summary

Problems solved by technology

However, the wet spinning process involved in this invention uses acetic acid solution as a collagen solvent, which has low solubility, and the acidic solvent has too strong binding force with collagen, and the evaporation speed is slow, which leads to fiber deposition and entanglement, and reduces the porosity of the material. What's more, it caused more than 70% damage to the triple helix structure

In addition, this patented technology needs to use sodium sulfate solution to promote protein salting out, so that the surface of collagen is closed, which further reduces the porosity of the material

In the follow-up treatment, although there is a short-term cleaning with dilute ethanol solution, the residue of sodium sulfate cannot be avoided; in addition, after cleaning, the as-spun silk needs to be kept at 60-80°C for 24-48 hours, and the production and processing cycle is longer; finally, with The water-soluble speed of the collagen spinning material processed by this process is slow, and it is not uniform enough, and there are flocs visible to the naked eye.
