Anti-mite man textile fabric
Technical field
The present invention relates to a kind of fabric, relate in particular to a kind of anti-mite man textile fabric.
Background technology
Mite class is the monoid of most species in Arthropoda arachnid, and on the earth, existing mite class can have 500,000 kinds more than, and their form, habit and habitat are varied, can find Anywhere on earth the trace of mite class.The disease that medical domain causes the dirt mite being distributed in people's living environment is studied, research shows that it is a kind of strong sensibiligen, the people in the whole world nearly 1/10 suffers from anaphylactia, and wherein the morbidity of asthma, allergic rhinitis and atopical dermatitis etc. is all closely bound up with existing of house dust mite.
Along with the development of world architecture technology and enriching of people's material life, indoor living environment has a very large change, the improvement of house airtight performance, indoor pollution is assembled, simultaneously improper ventilation has increased the growth that indoor humidity is also conducive to mould and house dust mite, thereby make dirt mite become allergen the most general in living environment, the change of life style and working method makes people 80% time spend indoor.The change of environment has promoted dirt mite to grow, and people have also increased and the contacting of dust mite allergen in the prolongation of indoor residence time, and the incidence of disease of the diseases such as dust mite allergy asthma increases thereupon.Therefore, the control of dirt mite has been subject to countries in the world researchers' extensive concern.
Because the textiles in room is the raw main place of dirt mite evil, by adding in textiles, there is the chemical reagent that kills mite or drive mite effect and give the anti-mite of textiles and drive mite function, in the process of using textiles, realize anti-mite and drive mite, become a kind of new trend.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of anti-mite man textile fabric.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A mite man textile fabric, the raw material blending that adopts following weight portion to form is weaved and is formed: 40-60 part cotton fiber, the anti-mite fiber of 40-60 part.
Anti-mite of the present invention man textile fabric can adopt industry universal method first cotton fiber and anti-mite fiber to be carried out to blending, makes blended yarn, then adopts industry universal method to be woven into anti-mite man textile fabric this blended yarn.The preparation method of obvious described blended yarn woven fabric itself does not have originality, is only to adopt prior art, and innovation of the present invention is the difference of fabric blend fibre raw material and proportioning.
Described anti-mite fiber, material is terylene, also contains 0.05-0.15wt% and drives mite agent.Describedly drive mite agent and formed by 30-50 weight portion Fenamidone, 30-50 weight portion decis and 10-30 weight portion lauryl sodium carboxymethyl type imidazoline acetate.
Fenamidone, CAS:161326-34-7.Decis, CAS:52918-63-5.Lauryl sodium carboxymethyl type imidazoline acetate, CAS:64041-76-5.
Described anti-mite fiber, is prepared from by following step:
(1) by terylene with drive mite agent and mix, extrude, cut into slices, make and drive mite terylene chips, wherein terylene is 100:0.05-100:0.15 with the mass ratio that drives mite agent;
(2) described in general, drive mite terylene chips heating and melting, extruding, the moulding of spray silk.
Further, described anti-mite fiber also contains the coupling agent of 0.02-0.10wt%.
Described coupling agent is titanate coupling agent.
Described coupling agent is comprised of 60-80wt% isopropyl three (dioctylphyrophosphoric acid acyloxy) titanate esters and 20-40wt% bis-(triethanolamine) metatitanic acid diisopropyl ester.
Isopropyl three (dioctylphyrophosphoric acid acyloxy) titanate esters, CAS:67691-13-8.Two (triethanolamine) metatitanic acid diisopropyl ester, CAS:36673-16-2.
Described anti-mite fiber, is prepared from by following step:
(1) coupling agent is mixed with terylene, obtain modified dacron, wherein the mass ratio of terylene and coupling agent is 100:0.02-100:0.10;
(2) by modified dacron with drive mite agent and mix, extrude, cut into slices, make and drive mite terylene chips, wherein terylene is 100:0.05-100:0.15 with the mass ratio that drives mite agent;
(3) described in general, drive mite terylene chips heating and melting, extruding, the moulding of spray silk.
Below main raw material fiber of the present invention is introduced:
Cotton fiber be epidermal cell by fertilization ovule through the seed fiber extending, thickening forms, be different from general bast fiber.Its chief component material is cellulose.The intensity of cotton fiber is high, wrinkle resistance good, draftability is poor; Heat resistance is better, is only second to fiber crops; Acid resistance is poor, at normal temperatures resistance to diluted alkaline; Dyestuff is had to good affinity, and easily, chromatogram is complete in dyeing, and color and luster is also more bright-coloured.
Cotton fiber moisture absorption and good permeability, soft and warming.Cotton is annual plant mostly.It is to be grown and formed by the epidermal cell growing on cotton seeds.The growth of cotton fiber can be divided into elongating stage, thickening phase and turn bent phase three phases.Cotton fiber is the main raw material of China's textile industry, and it accounts for very consequence in textile fabric.China is one of main Chan Mian state in the world, and at present, the output of cotton of China has entered prostatitis, the world.Cotton in China plantation almost spreads all over the country.Wherein take the Huanghe valley and the Yangtze river basin as main, add Northwest inland, Liaohe River Basin and south China, totally five large cotton regions.Cotton fiber length is 25-45mm, and line density is 1.2-2.2dtex left and right, powerful more than 4.5cN.Specifically can select Xinjiang to produce cotton fiber, 1.5 grades of average ranks, length 37mm, the long 41mm of product, fineness 1.59dtex, maturity 1.7, containing mixing 2.4%, short fiber content 10%.
Terylene is the trade name of the important kind ,Shi of in synthetic fiber China polyester fiber.It is to take fiber-forming polymer---the polyethylene terephthalate (PET) that p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) make through esterification or ester exchange and polycondensation reaction as raw material, the fiber of making through spinning and post processing.
Anti-mite of the present invention man textile fabric, mite-proof agent is embedded in fibrous inside, in the process that wears and wash textiles, surface one deck mite-proof agent is washed off, there is again new mite-proof agent to supplement from interior stripping, at fabric face, form again the anti-mite layer that one deck is new, bring into play anti-mite effect, thereby embody good washability.
Anti-mite of the present invention man textile fabric, has good anti-mite and drives mite effect.
