Abstract

The invention discloses a hear endurance high abrasion resistance warm keeping cashmere fiber. Chitosan fiber and cashmere are creatively blended, so that chitosans are evenly distributed; and the chitosans don't easily fall off and can penetrate into cell bodies for absorption, so as to disturb normal physiological activities of cells, thus the sterilizing effect is durable; anti-bacterial hollow polyester fiber is added to replace part of the cashmere fiber, so not only the cost is saved, but also the strength and the fatigue-resistance strength of the cashmere are improved; after the added nano silicon dioxide is improved by blending with acid for oxidation, carboxyl and hydroxyl group are produced, so the cashmere fiber has good dispersity and stability; after the surface of the manufactured cashmere crude fiber is grafted for decorative improvement with methacrylamide as a grafting monomer, the manufactured cashmere crude fiber is bonded with an unsaturated bond on the surface of the cashmere fiber, so the intermolecular force between the fibers is improved; the manufactured cashmere fiber has the use performances of high abrasion resistance and heat endurance, strong spinnability, and high warm keeping and health care performance; and during the producing process, chemicals are less discharged, thus the manufacturing method provided herein is an environmental-friendly production method.

Description

Warming cashmere fiber of a kind of heat endurance high abrasion and preparation method thereof

Technical field

The present invention relates to nonwoven material technical field, particularly relate to warming cashmere fiber of a kind of heat endurance high abrasion and preparation method thereof.

Background technology

The characteristics such as cashmere has carefully, light, soft, cunning is glutinous, thermal property is good, but output is rare, and being called as " fiber diamond " and " soft gold " is high-grade textile raw material.Due to the scale structure on cashmere fiber surface, in use there is the problems such as easy felting, easily balling-up in its goods, add cashmere fiber inherently native protein easily damage by worms, traditional post-processing approach often adopt antimicrobial fluid flood modification, often there is the defect that antibacterial effect is impermanent.Along with the progress of science and technology and the development of society, incident is ubiquitous electromagnetic radiation, atmosphere pollution, the harm such as dust pollution and electrostatic, people are not only confined to warmth retention property and Lightness to the functional requirement of cashmere fiber, people have also started there has been extraordinary demand to cashmere fiber, such as antistatic, dust-proof, waterproof, health-care and skin-care etc.
