CN105113049A - Fluffy and breathable cashmere fiber capable of promoting regeneration of skin and preparation method of fluffy and breathable cashmere fiber - Google Patents

Abstract

The invention discloses a fluffy and breathable cashmere fiber capable of promoting regeneration of skin and a preparation method of the fluffy and breathable cashmere fiber. A chitosan fiber and cashmere are creatively blended, so that chitosan is uniformly distributed, is difficult to fall and can permeate into a cell body to be adsorbed so as to disorder the normal physiological activity of a cell and thus kill bacteria, and the bactericidal effect is durable; the added modal fiber replaces part of the cashmere fiber, so that not only can the cost be saved, but also the cashmere strength is improved; the added expanded perlite is oxidized and modified by mixed acid so as to generate a carboxy group and a hydroxyl group, so that the fluffy and breathable cashmere fiber has favorable dispersibility and stability; the manufactured cashmere crude fiber is subjected to surface grafting modification by taking methacrylamide as a grafted monomer so as to be bonded with an unsaturated bond, so that the interfibrous intermolecular force is improved; the prepared cashmere fiber is fluffy and breathable, soft and smooth in hand feeling, high in resilience, long-term in wearing and capable of promoting regeneration of skin, and has a beautifying effect of beautifying and protecting skin.

Description

A kind of fluffy ventilative can the cashmere fiber promoting skin regeneration and preparation method thereof

Technical field

The present invention relates to nonwoven material technical field, particularly relate to a kind of fluffy ventilative can the cashmere fiber promoting skin regeneration 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.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provide a kind of fluffy ventilative can the cashmere fiber promoting skin regeneration and preparation method thereof.

The present invention is achieved by the following technical solutions:

The fluffy ventilative cashmere fiber that can promote skin regeneration, is made up of the raw material of following weight portion: cashmere fiber 34-36, Modal fibre 18-20, chitin fiber 13-15, expanded perlite 2-4, dioctyl azelate 4-6, isobutyl triethoxy silane 6-8, snail mucus 5-7, Methacrylamide 9-10, potassium peroxydisulfate 0.5-0.8, sodium oxalate 0.2-0.4, chlorination-1-butyl-3-methylimidazole 175-185, suitable quantity of water.

The described a kind of fluffy ventilative preparation method that can promote the cashmere fiber of skin regeneration, comprises the following steps:

(1) expanded perlite being put into volume ratio is the concentrated sulfuric acid of 3: 1 and the mixed solution of red fuming nitric acid (RFNA), reflux 4-5 hour at 100 DEG C, cooling, suction filtration, washing are to neutral, then in 100 DEG C of vacuum drying chamber inner drying 2-3 hour, extra-fine grinding obtains the expanded perlite micro mist of acid oxidase process;

(2) by adding isobutyl triethoxy silane, snail mucus ultrasonic oscillation grinding 2-3 hour after cashmere fiber, Modal fibre, chitin fiber oven dry, degreasing, ultra-fine grinding, in 100 DEG C of oven dry;

(3) chlorination-1-butyl-3-methylimidazole is dropped in reactor, add dioctyl azelate to stir and evenly mix, add step (1), (2) material grinding 30-50 minute, be heated to 105-115 DEG C, continue grinding and obtain spinning solution in 50-70 minute, spinning obtains modification cashmere crude fibre, is placed on freeze-day with constant temperature 80min in drying box for subsequent use after cold water cleaning;

(4) Methacrylamide is added water to be stirred to dissolve completely, adjust ph to 2, by bath raio 1: 20, drop into step (3) material and be placed in thermostat water bath and be heated to 80 DEG C, add other residual components, insulation reaction 60 minutes, washing and drying discharging.

Advantage of the present invention is: the invention by chitin fiber and cashmere blending, make shitosan be uniformly distributed difficult drop-off and absorption in cell body can be penetrated into, upset the normal physiological activity of cell and kill bacteria, bactericidal effect is lasting, add the Modal fibre Substitute For Partial cashmere fiber not only cost-saving intensity improving cashmere, the expanded perlite added creates carboxyl after nitration mixture oxidation modification, oh group, there is good dispersiveness and stability, in addition the present invention will obtain cashmere crude fibre take Methacrylamide as grafted monomers, carry out surface grafting modification, with the unsaturated bond bonding on cashmere fiber surface, improve interfibrous molecular separating force, obtained cashmere fiber is fluffy ventilative, soft smooth, high resilience, long-term dress can promote skin regeneration, there is the beauty functions of skin makeup skin care.
