Aids for dissolving wool keratin protein from wool, and its preparing method and use

Abstract

The invention relates to an auxiliary agent for dissolving wool keratin protein from wool, its preparation method and application, and belongs to the preparation of pure wool and other keratin fibrous protein solutions, keratin protein films, powders and blocks and their additives. Technology for shaping keratin. The auxiliary agent is composed of a solvent, a bond-opening reducing agent, a surfactant, a cross-linking agent and water. The weight percentages are: 5%-25% of solvent, 10%-20% of reducing agent, 0.5%-5% of surface active agent, more than 0% to equal to or less than 8% of cross-linking agent, and the rest is water. The preparation method is that the wool is immersed in the prepared auxiliary agent to dissolve, the dissolution temperature is 50-80 DEG C, the dissolution time is 4-10 hours, and the keratin protein solution is filtered out. The auxiliary agent is also suitable for cashmere, yak hair, yak cashmere, camel hair, camel hair and other animal hair keratinoid fibers.

Description

Technical field [0001] The invention relates to an auxiliary agent for dissolving wool keratin protein from wool, and a preparation method and application thereof. The auxiliary agent can dissolve wool keratin protein from wool, and then prepare wool keratin protein solution and products thereof. Background technique [0002] my country is rich in wool resources and is also a big country in wool spinning industry. Due to the limitations of wool quality, breeding management and textile technology, a large number of short fibers and crude fibers are discarded every year, which not only causes waste of keratin resources, but also pollution surroundings. Therefore, studying the regeneration and utilization of waste wool fibers and their methods is of great significance to the effective utilization and protection of natural resources. Although the regeneration technology of wool keratin protein has been studied for a long time, there are few reports on related applications. [0003] P...

Problems solved by technology

Therefore, if keratin protein is extracted under alkaline conditions, the obtained keratin protein solution will inevitably have low concentration, low production rate, small molecular weight, and difficult control of process parameters.

[0008] Although the above-mentioned patent report is related to the dissolving treatment and utilization of keratin protein, it is different from the chemical reagent used in the present invention, the solvent principle, the acidity and alkalinity of the lysate, and is also different from the preparation method of the present invention.
