CN105256386A - Velvet fibers with deodorization and flame retardant functions and manufacture method thereof - Google Patents

Abstract

The invention discloses velvet fibers with deodorization and flame retardant functions and manufacture method thereof. Chitosan fibers and cashmere are creatively blended, so that chitosan can be evenly distributed and is not subject to falling off, and can penetrate into a cell body to be adsorbed on the cell body, normal physiological activities of the cell can be disturbed, and then bacteria can be killed; added nano mullite fibers are oxidized and modified by mixed acid to generate carboxyl and hydroxyl groups, and have excellent dispersibility and stability; furthermore, obtained velvet crude fibers take methacrylamide as grafting monomers, and are modified by surface grafting, so that intermolecular forces among fibers are improved, the obtained velvet fibers have elasticity and warmth retention property of wool, and good properties of rabbit hair, and the products have the advantages of deodorization and flame retardant functions, soft and smooth hand feeling, natural and elegant gloss, and good warmth retention property, and can meet requirements of high consumption groups.

Described a kind of preparation method with the VELVET fiber of deodorizing anti-flaming function, comprises the following steps:

(1) nano mullite fiber 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 mullite fiber of acid oxidase process;

(2) by adding oxidized starch after cashmere, the rabbit hair, ramee, chitin fiber oven dry, degreasing, ultra-fine grinding, flores aurantii essential oil, γ aminopropyl triethoxysilane ultrasonic oscillation grind 2 hours, in 100 DEG C of oven dry;

(3) chlorination-1-butyl-3-methylimidazole is dropped in reactor, add Cocoamidopropyl betaine 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 VELVET 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, the nano mullite fiber added creates carboxyl after nitration mixture oxidation modification, oh group, there is good dispersiveness and stability, in addition the present invention will obtain VELVET crude fibre take Methacrylamide as grafted monomers, carry out surface grafting modification, improve interfibrous molecular separating force, obtained VELVET fiber tool elasticity laniferous, warmth retention property, the premium properties of the rabbit hair, product is made to have deodorizing fire-retardant, soft sliding glutinous feel, the advantages such as naturally graceful gloss and good warmth retention property, can suitable comparatively high consumption horizontal stratum demand.
