Problems solved by technology

However, because the molecular structure of acrylic fiber is relatively regular, and it 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 poor. Traditional chemical modification consumes a lot of water and chemicals, which is not only complicated to operate, but also pollutes the environment

Abstract

The invention discloses a method for preparing a superfine acrylic fiber modified by porous collagen, and the method comprises the following steps of: dissolving polyacrylonitrile into a solvent, adding polyvinylpyrrolidone, uniformly stirring them to prepare fiber polymer solution; at 40 degrees centigrade, adding collagen solution into the fiber polymer solution, magnetically stirring to an uniform state and standing, and finally preparing into collagen-modified fiber polymer solution; adding SiO2 nano-particles into the collagen-modified fiber polymer solution, magnetically stirring to the uniform state as spinneret solution; injecting the spinneret solution into an ejector, spinning under the additional electric field, depositing it into a collecting unit by controlling spinning time and moving a receiving screen, and finally calcining; soaking the acrylic fiber containing the SiO2 nano-particles with HF (Hydrogen Fluoride) solution, slowly stirring, cleaning and drying to prepare the superfine acrylic fabric modified by porous collagen. Through the preparation method, fabric is improved in dyeing property, the acrylic fiber has the soft and smooth hand feel and the silk-like effect.

Description

technical field [0001] The invention relates to a preparation method of ultrafine acrylic fibers, in particular to a preparation method of porous 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, and it 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 poor. Traditional chemical modification consume...
