preparation example Construction

[0052] In an optional embodiment, the preparation method of the wool keratin solution includes the following steps: take waste wool or scrap wool, dry it after washing, add peracetic acid with a concentration of 3% to 10% for oxidation, and then After washing and dehydrating, the wool is taken and added with an alkali solution with a concentration of 3% to 10% for hydrolysis, and the filtrate is filtered and diluted to obtain a wool keratin solution.

[0053] The preparation method for the wool keratin solution provided by the present invention can fully utilize resources and reduce the cost of the wool keratin solution by using waste or leftover wool, thereby reducing the cost of the final product. Among them, through rational screening of oxidant and hydrolyzing agent, the obtained wool keratin solution contains more protein macromolecules, so as to promote the comparison between the hydroxyl groups in the cotton fiber macromolecules and the polar groups in the protein macrom...

Abstract

The invention provides a cotton fiber modifying agent, a modified cotton fiber and a preparation method thereof. The cotton fiber modifying agent comprises a traditional Chinese medicine composition.The traditional Chinese medicine composition is prepared from, by weight, 10-60 parts of flos caryophylli and / or radix astragali, 10-60 parts of rhizoma coptidis and / or cortex phellodendri, 5-50 partsof sophora alopecuroides and 10-70 parts of folium geranii dahurici. By reasonable compatibility of components of the traditional Chinese medicine composition and reasonable content values, the traditional Chinese medicine composition contains antibacterial and mould-proof functional substances and tannin substances, combination of functional components in the traditional Chinese medicine composition and cellulose macromolecular groups in cotton fibers is promoted to realize hydroxyl radical formation, macromolecular interaction is enhanced, functional durability and stability of the traditional Chinese medicine composition are maintained, and antibacterial and mould-proof effects of the cotton fibers are achieved.

Description

technical field [0001] The invention belongs to the technical field of cotton fiber modification, and in particular relates to a cotton fiber modifier, modified cotton fiber and a preparation method thereof. Background technique [0002] Cotton fiber has been widely used as a textile material since ancient times because of its unique and excellent properties such as softness, warmth retention, good hygroscopicity, and comfort. However, cotton fiber itself also has deficiencies that cannot be ignored, such as easy to mold, easy to breed bacteria, poor anti-wrinkle and non-ironing properties, and single use. The cotton fiber is modified by using the plant traditional Chinese medicine extract micropowder composition, so that the active ingredients of the plant traditional Chinese medicine are "implanted" into the cotton fiber, endowing the cotton fiber with good antibacterial and anti-mildew functions, and meeting the needs of consumers. [0003] Bacteria and molds are widely ...
