Problems solved by technology

[0007] At present, the research on fish collagen is mainly concentrated in the beauty, health care, food and other industries, and there is no report on the preparation of composite fibers purely using fish collagen
In addition, from the research on the structure and performance differences of collagen, the research on the differences between fish collagen and traditional pigskin and cowhide protein is still in its infancy

Embodiment 1

[0054] 1. Decalcification: Soak 1 kg of frozen fish skin in tap water at 4°C and rinse until there is no other solid matter outside the whole fish skin in the soaking solution, then soak and rinse with deionized water for 5 times. Fish skin was soaked in 6% (W / V) NaCl solution for 1 day to remove non-collagen, and then soaked in disodium ethylenediaminetetraacetic acid (EDTA) solution for decalcification.

[0055] 2. Extraction of acid-soluble collagen (ASC): add decalcified fish skin to 0.5mol / L HAc and 0.1mol / L HC1 solution respectively, soak for 2 days, centrifuge (10 000×g, 30 min), and take the supernatant The liquid was repeatedly centrifuged once, and the supernatants were combined to obtain a crude ASC extract.

[0056] 3. Enzymatic acid-soluble collagen (PSC) extraction: put the residue obtained in step 2 into 0.5mol / L HAC and 0.1mol / L HC1 solutions containing 1% (W / V) pepsin, stir and digest On 2 days, centrifuge (10 000 × g, 30 min), take the supernatant, repeat th...

Decalcification: Clean fish scales, fish cartilage, etc., soak and rinse 1 kg of frozen fish scales and fish cartilage with 4°C tap water until there are no other solids in the soaking solution, then soak and rinse with deionized water for 5 times . Soak fish scales and cartilage in 6% (W / V) NaCl solution for 1 day to remove non-collagen, and then soak in disodium ethylenediaminetetraacetic acid (EDTA) solution for decalcification.

[0065] 2. Extraction of acid-soluble collagen (ASC): Add 0.5mol / L HAc and 0.1mol / L HC1 solution to decalcified fish scales and fish cartilage at a ratio of 5:3, soak for 2 days, centrifuge (10 000×g, 30 rain), the supernatant was taken and centrifuged repeatedly once, and the supernatant was combined to obtain the crude ASC extract.

[0066] 3. Enzymatic acid-soluble collagen (PSC) extraction: put the residue obtained in step 2 into 0.5mol / L HAC and 0.1mol / L HC1 solutions containing 1% (W / V) pepsin, stir and digest 2 days, centrifuge (...

Abstract

The invention discloses fish collagen composite fibers and a preparation method thereof. The fish collagen composite fibers comprise the following components in parts by weight: 100 parts of fish collagen, 0.01-10 parts of nano gold sol and / or nano silver sol and 100-800 parts of polyvinyl alcohol. The method comprises the following steps: (1) extracting and separating fish collagen; (2) enabling the fish collagen and nano gold and / or nano silver to carry out a composite copolymerization and cross-linking reaction according to the proportion; (3) mixing a modified fish collagen solution with a polyvinyl alcohol solution and stirring the mixed solution; and (4) carrying out spinning, drawing and hydroformylation after carrying out deaeration and filtration on the spinning solution of the fish collagen composite fibers to obtain the fish collagen composite fibers. The fish collagen composite fibers and the preparation method have the following effects: the flexibility of the composite fibers can be improved; and the strength and elongation of the collagen composite fibers can be substantially improved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a fish collagen composite fiber and a preparation method thereof. Background technique [0002] Protein is the material basis of all life, and collagen is the most abundant type of protein. Collagen is a natural protein, it has strong biological activity and biological function, can participate in the migration, differentiation and reproduction of cells, so that bone tendon, cartilage and skin have a certain mechanical strength, because of its antigenicity and With good biocompatibility, it is widely used in medical and health fields such as burns, trauma, corneal diseases, cosmetology, hard tissue repair, and wound hemostasis. [0003] Collagen is a fibrous protein with a unique rod-shaped helical structure and excellent physical and mechanical properties. Compared with general vegetable protein, it has higher strength. The moisturizing performance of collagen is particu...
