Abstract
The invention discloses an ecological anti-bacterium down feather fiber capable of releasing anions. The ecological anti-bacterium down feather fiber is characterized by comprising, by weight, 29 parts to 34 parts of grey duck down, 8 parts to 10 parts of silk fibers, 4 parts to 7 parts of cattail fibers, 4.3 parts to 7.2 parts of chitin, 5 parts to 8 parts of KH-550, 2 parts to 4 parts of nanometer titanium dioxide, 0.2 part to 0.5 part of magnesium sulfate, 2 parts to 3 parts of diatom ooze, 0.6 part to 0.9 part of acrylamide, 165 parts to 185 parts of 1-butyl-3-methylimidazole chloride and a proper amount of water. According to the ecological anti-bacterium down feather fiber, chitin molecules are adsorbed to the surface of the down feather fiber through chemical modification, normal physiological activities of cells are disturbed to kill bacteria, and meanwhile the anti-bacterium performance is thorough in cooperation with the photo-catalytic oxidation anti-bacterium effect of the nanometer titanium dioxide; the manufactured ecological anti-bacterium down feather fiber has the function of releasing the anions; meanwhile, the anti-bacterium effect is obvious, the long-term effect is achieved, the heat preservation effect is obvious, the fluffy degree is high, and use crowds are greatly increased.
Description
Technical field
The present invention relates to nonwoven material technical field, be specifically related to a kind of ecological bacteriostatic down fiber capable of releasing negative ion and preparation method thereof.
Background technology
Down fiber belongs to natural protein fibre, there is the advantages such as matter is soft, light weight, bulkiness are high, warmth retention property is good, be widely used in clothes, wadded a quilt with cotton, the fields such as filler of weaving, along with the raising of people's living standard, the change of consumption structure, and in recent years to promotion that is green, low-carbon (LC), the requirement of people to down products is more and more higher, should style be newly comfortable and easy to wear requires again antibacterial, ventilating warming.In order to adapt to consumer demand and hobby, a kind of low-density, Halogen, environmental protection, ecological bacteriostatic, the novel down fiber that water-fastness, resistance to elevated temperatures is high and the research of various performance imperative.
Chitin is the uniquely positively charged tunicin that occurring in nature is found up to now.Chitin fiber cross section shapes is irregular ellipse, longitudinally has hole, and its interior molecules composition and cellulose family are seemingly.Chitin fiber has good hygroscopicity, film forming, dyeability and antibiotic property, can with the fiber blend such as cotton and viscose glue.Along with the carrying out of a large amount of fundamental and applied research in recent years, chitin and derivative thereof have demonstrated the using value of its uniqueness at numerous areas such as chemical industry, weaving, printing and dyeing, papermaking, medicine, food, environmental protection.But due in chitin molecule, intermolecularly have strong hydrogen bond action, make chitin be crystalline structure closely, be insoluble to usual vehicle, make it processing difficulties, thus limit it and apply.Therefore, in chitin molecule, introduce other functional group or by grafting, blended to improve its dissolubility and molding processibility produces functional material, just become research the most active in chitin research in recent years.
Summary of the invention
Object of the present invention is just to provide a kind of ecological bacteriostatic down fiber capable of releasing negative ion and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of ecological bacteriostatic down fiber capable of releasing negative ion, it is characterized in that, be made up of the raw material of following weight portion: grey duck down 29-34, silk fiber 8-10, cattail fiber 4-7, chitin 4.3-7.2, KH-550 5-8, nano titanium oxide 2-4, magnesium sulfate 0.2-0.5, diatom ooze 2-3, acrylamide 0.6-0.9, chlorination-1-butyl-3-methylimidazole 165-185, suitable quantity of water.
The preparation method of described ecological bacteriostatic down fiber a kind of capable of releasing negative ion, is characterized in that comprising the following steps:
(1) by diatom ooze in 690-800 DEG C of high-temperature calcination process 1-2 hour, be cooled to room temperature fragmentation, add magnesium sulfate solution soak 5-8 hour, add acrylamide extra-fine grinding 2-4 hour, spraying dry;
(2) cattail fiber is put into salt solution and soak 5-8 hour, oven dry is pulverized, and adds KH-550, nano titanium oxide puts into 50-70 DEG C of stirred in water bath 30-50 minute, dries;
(3) chitin, chlorination-1-butyl-3-methylimidazole are stirred and evenly mixed, add step (1), (2) material grinding 20-40 minute, be heated to 80-90 DEG C, keep temperature to stir 1-3 hour;
(4) drop in step (3) material after grey duck down defatted superfine being pulverized, be warming up to 110-120 DEG C, add other residual components stirring reaction 50-70 minute, obtained spinning solution;
(5) obtained spinning solution carried out spinning, winding, boundling, stretching and get final product.
The present invention has following beneficial effect: cattail fiber grain is bonded in nano titanium oxide surface by physicochemical manner by the present invention, diatom ooze after simultaneously composite modified carries out cross-linking modified to chitin together, improve the absorption property of chitin, can forever be combined with down fiber, difficult drop-off, the chitin being adsorbed on down fiber surface is combined with the saliva of microorganism phosphatide, penetrate into the cytoplasm with anion in absorption in cell body, and there is flocculation, upset the normal physiological activity of cell and kill bacteria, nano titanium oxide is photochemical catalytic oxidation Antibacterial Mechanism, the two serves the effect of Synergistic antimicrobial, anti-microbial property is thorough, the ecological bacteriostatic down fiber utilizing the present invention to obtain compared with prior art, not only there is negative ion-releasing function, simultaneously antibacterial effect obviously and have long-lasting, the obvious bulking intensity of warming effect is high, considerably increase use crowd.
