Problems solved by technology

However, because the molecular structure of acrylic fiber is relatively regular, but because acrylic fiber is a synthetic fiber, which belongs to hydrophobic fiber, the macromolecule lacks hydrophilic groups, the molecular chain structure is tight, the degree of crystallinity and orientation are high, and its hydrophilicity is relatively high. Poor, traditional chemical modification consumes a lot of water and chemicals, not only complicated operation, but also pollutes the environment

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 [0001] The invention relates to a preparation method of ultrafine acrylic fibers, in particular to a preparation method of collagen modified ultrafine acrylic fibers. Background technique [0002] At present, with the improvement of people's living standards and the continuous renewal of consumption concepts, consumers have higher and higher requirements for the quality, variety and color of acrylic textiles. The commonly used acrylic fiber is a kind of synthetic fiber, which has always been favored by the market because of its soft, fluffy, and good warmth retention properties, and can replace wool. However, because the molecular structure of acrylic fiber is relatively regular, but because acrylic fiber is a synthetic fiber, which belongs to hydrophobic fiber, the macromolecule lacks hydrophilic groups, the molecular chain structure is tight, the degree of crystallinity and orientation are high, and its hydrophilicity is relatively high. Poor, traditional ...
