Abstract
A preparation method of collagen modified superfine acrylic fiber comprises steps as follows: polyacrylonitrile is dissolved in a solvent, and polyvinylpyrrolidone is added and uniformly stirred to prepare a fiber polymer solution; a collagen solution is added into the fiber polymer solution at the environment of 40 DEG C, magnetically stirred to be uniform and subjected to standing to serve as a spinning solution; and the spinning solution is filled into an injector, spinning is performed under the action of an additional electric field, and spinning fiber is settled in a collecting device by controlling the spinning time and moving a receiving screen and is sintered to obtain the collagen modified superfine acrylic fiber. With adoption of the preparation method, the structural controllability of fabric can be improved, and the modified acrylic fiber touches soft and smooth and has an effect of simulated silk.
Description
Technical field
The present invention relates to a kind of preparation method of ultra-fine acrylic fibers, particularly relate to a kind of preparation method of collagen-modified ultra-fine acrylic fibers.
