The ecological bacteriostatic down fiber prepared by the method provided by the invention has the characteristics of magnetic physical therapy efficacy, light weight and good fluffy degree, and excellent heat retention, etc.

Description

A kind of light weight fluff type ecological bacteriostatic down fiber and preparation method thereof

Technical field

The present invention relates to nonwoven material technical field, be specifically related to a kind of light weight fluff type 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 a kind of light weight fluff type 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:

A kind of light weight fluff type ecological bacteriostatic down fiber, it is characterized in that, be made up of the raw material of following weight portion: white duck down 30-35, pearl fiber 2-4, mercerized cotton fiber 4-7, chitin 3.7-5.8, nano ferriferrous oxide 1.3-2.3, butyl titanate 6-9, straw charcoal 3-5, sodium humate 0.6-0.8, chlorination-1-butyl-3-methylimidazole 175-185, suitable quantity of water.

The preparation method of described a kind of light weight fluff type ecological bacteriostatic down fiber, is characterized in that comprising the following steps:

(1) by straw charcoal in 450-520 DEG C of high-temperature calcination process 1-2 hour, be cooled to room temperature fragmentation, add sodium humate aqueous solution soaking 5-8 hour, add pearl fiber extra-fine grinding 2-4 hour, spraying dry;

(2) mercerized cotton fiber is put into salt solution and soak 5-8 hour, oven dry is pulverized, and adds nano ferriferrous oxide, butyl titanate 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 white duck down defatted superfine being pulverized, be warming up to 110-120 DEG C, stirring reaction 50-70 minute, obtained spinning solution;
