Marine-mud-containing multifunctional polyacrylonitrile fiber and preparation method thereof

Abstract

The invention discloses a marine-mud-containing multifunctional polyacrylonitrile fiber and a preparation method thereof. The marine-mud-containing multifunctional polyacrylonitrile fiber comprises a polyacrylonitrile solution and a marine mud concentrated solution; in percentage by weight, the marine mud concentrated solution consists of 5 to 35% of marine mud powder, 0.5 to 3% of extract of clinacanthus nutans, 1.2 to 5% of extract of choerospondiasaxillaris bark, 0.3 to 2.5% of extract of ledum palustre, 0.5 to 3% of coupling agent and the balance of deionized water; the polyacrylonitrile solution accounts for 85 to 98% of the total weight of the fiber; the marine mud concentrated solution accounts for 2 to 15% of the total weight of the fiber. The fiber obtained by processing all the raw materials through various approaches not only reserves the original advantages of a polyacrylonitrile fiber, but also has fragrant odor, good skin friendliness, hygroscopicity, spinnability and good dyeing property and high fiber forming strength. Wearability is more excellent; effects of resisting to bacteria and deodorizing, resisting to ultraviolet rays, removing mites and repelling mosquitoes and resisting to static electricity are realized, and nutritional health-care ingredients are released, so that a human body obtains more health benefits; moreover, marine mud resources are sufficiently utilized and have huge social and economic benefits.

Description

technical field [0001] The invention relates to a multifunctional polyacrylonitrile fiber containing sea mud and a preparation method thereof, belonging to the technical field of functional chemical fibers. Background technique [0002] Polyacrylonitrile fiber usually refers to acrylonitrile copolymer or homopolymer fiber containing more than 85% acrylonitrile, acrylic for short in my country. Because of its crispness, bulkiness, warmth retention, good light resistance and radiation resistance, high resilience, soft touch, mildew and moth resistance, and easy blending with wool and cotton, it is very suitable for making underwear, socks, bedding, And knee pads, elbow pads, wrist pads and other close-fitting fabrics have occupied a large market. However, because the acrylic fiber macromolecule does not contain hydrophilic groups, it has poor hygroscopicity, is prone to static electricity, stains and vacuums, resulting in poor wearing performance, stuffy feeling when wearing,...

AI Technical Summary

Problems solved by technology

However, sea mud has a strong fishy smell, high colloidal properties, and low permeability coefficient, which limits its application in many fields such as textile fibers.

After searching, so far, no fiber blended with sea mud and polyacrylonitrile has been found at home and abroad to have antibacterial and deodorizing, anti-ultraviolet, mite and mosquito repellent, antistatic, moisture absorption and breathable, skin care and health care functions. see literature report
