Description

A kind of nano-antibacterial Anti-moth-eating cashmere composite fibre and preparation method thereof

Technical field

The present invention relates to nonwoven material technical field, be specifically related to a kind of nano-antibacterial Anti-moth-eating cashmere composite fibre and preparation method thereof.

Background technology

Cashmere is that growth is at goat appearance cortex, cover the high-grade natural fabric thin and bending one by one at goat coarse wool root, wherein containing a lot of air, and form air layer, the invasion and attack of external cold air can be defendd, retain body temperature can not lower, there is the title of " fiber jewel ", " fiber queen ".Because output is rare, the more important thing is its excellent quality and characteristic, have light, soft, sliding, glutinous feature, is that all textile raw materials that the current mankind can utilize are all incomparable, and be thus otherwise known as " soft gold ".

Goat cashmere mainly originates in China, owing to limiting by kind, goat is greater than sheep for the consumption of grassland and vegetation, and input-output ratio is relatively on the low side, thus cause the cultivation quantity of goat to decline to some extent, in addition due to the change of rearing conditions and to goat improvement, the fineness of goat cashmere is thicker year by year; Along with the raising of people's living standard, to the demand of cashmere product at quality and quantity and functionally expand just gradually, increasing wool textile enterprises joins cashmere and produces, and makes this just rare goat cashmere resource costly, and this brings very large managerial risk also to many enterprises; Cashmere fiber itself is a kind of native protein, and its manufactured goods certainly exist many defects, is such as subject to damage by worms, easily balling-up, easily to play electrostatic, not wear-resisting, not radiation proof, intensity low etc.If the composite fibre of cashmere fibres and other fiber blends can be prepared, just when reducing costs, the new product not being worse than pure cashmere fiber textile quality can be obtained.
