Abstract

The invention provides a preparation method of collagen regenerated cellulose fiber. The preparation method comprises the following steps: preparing viscose spinning dope; adding collagen solution into the viscose spinning dope, wherein the adding quantity of the collagen accounts for 4-15% of the mass of the methylcellulose of the viscose spinning dope; evenly mixing to obtain protein viscose mixed liquid; adding an initiator into the mixed liquid, wherein the adding quantity of the initiator accounts for 2.3-5% of the mass of the collagen; after that, stirring at the temperature of 19-25 DEG C for 2-8h to obtain spinning solution; filtering and defoaming the spinning solution, and then carrying out wet spinning. After the preparation method is adopted, the collagen is successfully grafted into the regenerated cellulose fiber, and the collagen regenerated cellulose fiber can be spun; the grafting efficiency and the grafting rate of the method are high; the obtained collagen fiber has silk-like gloss and is fluffy and soft in hand feeling.

Description

technical field [0001] The invention belongs to the technical field of textile fiber processing, and in particular relates to a preparation method of collagen regenerated cellulose fibers. Background technique [0002] Collagen is a kind of natural fibrous protein, which mainly exists in animal skin, bone, tendon and other tissues. It is an important structural protein in connective tissue and plays the role of supporting organs and protecting the body. Collagen, also known as collagen, has a molecular weight of 300,000 Daltons. It is composed of two I chains and one II chain, forming a triple helix structure. The three peptide chains are intertwined with the unique left-handed α-chain to form a right-handed composite helical collagen, which is characterized by a chain Gly-x-y periodic structure of amino acids. [0003] There are ionic bonds, hydrogen bonds, Van der Waals forces and hydrophobic bonds generated by non-polar groups among the collagen peptide chains. At the s...
