Abstract

The invention relates to a multi-purpose gelatin fiber and a preparation method thereof, in particular to the preparation of amphipathy polymer and emulsion thereof, the preparation of spinning solution, fiber spinning, after-treating of the fiber and the like, wherein firstly free radical polymerization or polyurethane prepolymer is adopted for compounding amphipathy polymer which is prepared into emulsion in water, and then the emulsion is added into a gelatin solution to prepare spinning solution with certain viscosity; the spinning solution is prepared in to fiber by a wet spinning; and finally in order to increase the intensity of the fiber, the fiber is needed to be post-treated. The gelatin fiber and the preparation method thereof belong to the textile industry technical field; andthe formed fiber can be used for clothing material, biology medical material and hairpiece products.

Description

technical field [0001] The invention relates to a multi-purpose gelatin fiber and its preparation method, in particular to the preparation of amphiphilic polymer and its emulsion, the preparation of spinning solution, the spinning of fiber and the post-treatment of fiber, etc. The preparation method belongs to textile In the field of industrial technology, the formed fibers can be used in clothing materials, biomedical materials and wig products. Background technique [0002] All linear macromolecules with a molecular weight above 3000 can be made into fibers by appropriate methods. Collagen is the most abundant protein in mammals. Due to its unique triple helix structure, good biocompatibility and biodegradability, it has been widely used in biomedical materials and polymer composite materials in recent years. attention. However, there are not many successful examples of preparing spinnable fibers from collagen or its denatured product gelatin. The preparation method of ...
