Description

One can textile ecological bacteriostatic down fiber and preparation method thereof

Technical field

The present invention relates to nonwoven material technical field, being specifically related to one can textile ecological bacteriostatic down fiber 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 one can textile ecological bacteriostatic down fiber and preparation method thereof, to overcome the deficiencies in the prior art.

The object of the present invention is achieved like this:

One can textile ecological bacteriostatic down fiber, it is characterized in that, be made up of the raw material of following weight portion: goose down 14-16, goose feather 25-35, polyester fiber 3-5, Modal fibre 4-7, chitin 3.6-6.7, zirconium sulfate 0.2-0.5, montmorillonite 1-3, amido silicon oil 6-9, nano titanium oxide 1.5-2.5, chlorination-1-butyl-3-methylimidazole 150-180, suitable quantity of water.

Described a kind of can the preparation method of textile ecological bacteriostatic down fiber, it is characterized in that comprising the following steps:

(1) by montmorillonite in 710-800 DEG C of high-temperature calcination process 1-2 hour, be cooled to room temperature fragmentation, add zirconium sulfate aqueous solution grinding 2-4 hour, spraying dry;

(2) polyester fiber is put into salt solution and soak 5-8 hour, oven dry is pulverized, and adds amido silicon oil, 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) goose down, goose feather defatted superfine are dropped in step (3) material after pulverizing, 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: polyester fiber particle is bonded in nano titanium oxide surface by physicochemical manner by the present invention, montmorillonite powder after simultaneously composite modified carries out cross-linking modified to chitin together, improve the absorption property of chitin, chitin molecule can be forever combined, difficult drop-off with down fiber, the chitin being adsorbed on down fiber surface is combined with the saliva of microorganism phosphatide, microorganism is wrapped, adsorb by penetrating in cell body, with the cytoplasm of anion 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 separately or can mix with other textile fabric and carries out processing nonwoven products or textiles, product have can textile good, warmth retention property is good, light weight good springiness, moisture pick-up properties is good, the features such as presentation quality is good, can be applicable in weaving or non-woven field.
