Abstract
The invention discloses a light-resistance and antistatic cashmere fiber. Chitosan fibers and cashmere are creatively blended, so that chitosan can be distributed evenly without being prone to falling off and can penetrate into cells for absorption, bacteria is killed by disturbing normal physiological activities of the cells, lasting sterilization effect is achieved, acrylic fibers are added to replace part of the cashmere fibers to save cost and improve light resistance of the cashmere, nano-calcium oxide is added to produce carboxyl and hydroxyl polar groups after oxidative modification via mixed acid, good dispersibility and stability are achieved, prepared crude cashmere fibers take methacrylamide as grafted monomers, surface graft modification is performed, the monomers are bonded with unsaturated bonds of cashmere fiber surfaces, intermolecular forces among the fibers is improved, breaking strength is improved, and the prepared cashmere products are exquisite, soft, light and antistatic in hand feel.
Description
Technical field
The present invention relates to nonwoven material technical field, particularly relate to a kind of fast light anlistatig cashmere fiber 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, provides a kind of fast light anlistatig cashmere fiber and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of fast light anlistatig cashmere fiber, is made up of the raw material of following weight portion: cashmere 25-28, chicken feather 22-24, acrylic fiber 13-15, chitin fiber 11-12, lauric acid amide of ethanol 3.4-3.7, nano calcium oxide 3-5, aminopropyl triethoxysilane 7-9, banana tegument extract 1.2-1.5, Methacrylamide 8-10, potassium peroxydisulfate 0.2-0.4, Calcium Ascorbate 0.1-0.3, chlorination-1-butyl-3-methylimidazole 170-175, suitable quantity of water.
The preparation method of described a kind of fast light anlistatig cashmere fiber, comprises the following steps:
(1) nano calcium oxide 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, grinding obtains the nano calcium oxide of acid oxidase process;
(2) by adding banana tegument extract, aminopropyl triethoxysilane ultrasonic oscillation grinding 2-3 hour after cashmere, acrylic fiber, chicken feather, 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 lauric acid amide of ethanol 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, interpolation acrylic fiber Substitute For Partial cashmere fiber is not only cost-saving improves cashmere light resistance, the nano calcium oxide added creates carboxyl after nitration mixture oxidation modification, oh group, there is good dispersiveness and stability, to 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, ultimate strength increases, obtained cashmere product feel is fine and smooth, soft, merrily and lightheartedly, antistatic.
