Anti-mite modal fiber fabric
Technical field
The present invention relates to a kind of fabric, particularly relate to a kind of anti-mite modal fiber fabric.
Background technology
Mite class is the monoid of most species in Arthropoda arachnid, and mite class existing on the earth can have 500,000 kinds more than, and their form, habit and habitat are varied, can find the trace of mite class on earth Anywhere.Medical domain is studied the disease that the dirt mite be distributed in people's living environment causes, 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 the abundant of people's material life, indoor living environment has a very large change, the improvement of house airtight performance, indoor pollution is assembled, improper ventilation adds the growth that indoor humidity is also conducive to mould and house dust mite simultaneously, thus making dirt mite become allergen the most general in living environment, the change of life style and working method then makes the time of people 80% spend in indoor.The change of environment facilitates dirt mite and grows, and people too increase the contact with 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 receives the extensive concern of countries in the world researcher.
Because the textiles in room is the main place of dirt mite evil life, there is the chemical reagent that kills mite or drive mite effect give the anti-mite of textiles by adding in textiles and drive mite function, in the process using textiles, realize anti-mite 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 modal fiber fabric.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of anti-mite modal fiber fabric, the raw material hybrid woven adopting following weight portion to form forms: 50-70 part Modal fibre, 30-50 part mite-assistant fiber.
Anti-mite modal fiber fabric of the present invention can adopt industry universal method first Modal fibre and mite-assistant fiber to be carried out blending, obtained blended yarn, then adopts industry universal method to be woven into anti-mite modal fiber 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 mite-assistant fiber, material is terylene, also drives mite agent containing 0.05-0.15wt%.Describedly drive mite agent and be made up of 30-50 weight portion Fenamidone, 30-50 weight portion decis and 10-30 weight portion lauryl carboxymethyl sodium form imidazoline acetate.
Fenamidone, CAS:161326-34-7.Decis, CAS:52918-63-5.Lauryl carboxymethyl sodium form imidazoline acetate, CAS:64041-76-5.
Described mite-assistant fiber, is prepared from by following step:
(1) by terylene with drive mite agent and mix, extrude, cut into slices, obtainedly drive mite terylene chips, wherein terylene is 100:0.05-100:0.15 with the mass ratio driving mite agent;
(2) drive mite terylene chips heating and melting by described, extruding, spray silk is shaping.
Further, the coupling agent of described mite-assistant fiber also containing 0.02-0.10wt%.
Described coupling agent is titanate coupling agent.
Described coupling agent is made up 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 mite-assistant fiber, is prepared from by following step:
(1) mixed with terylene by coupling agent, 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, obtainedly drive mite terylene chips, wherein terylene is 100:0.05-100:0.15 with the mass ratio driving mite agent;
(3) drive mite terylene chips heating and melting by described, extruding, spray silk is shaping.
Below main raw material fiber of the present invention is introduced:
Modal fibre, be called for short Modal fiber, be the tModified Cellulose Fibers of the koplon of Austrian Lenzin (Lenzing) company exploitation, the raw material of this fiber adopts the beech in Europe, first be made into wood pulp, then be processed into fiber by special spinning technique.This products material is all natural material, harmless, and can natural decomposition, environmental sound.The raw material of Modal fibre is the spinney originating from Europe, and being made through special spinning technique after making wooden slurries, is a kind of cellulose fibre, belongs to cellulose fibre together so the same with cotton, is pure natural fabric.
Terylene is an important kind in synthetic fiber, is the trade name of China's polyester fiber.It is with p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) for raw material is through esterification or ester exchange and polycondensation reaction and obtained fiber-forming polymer---polyethylene terephthalate (PET), through the fiber that spinning and post processing are made.
Anti-mite modal fiber fabric of the present invention, mite-proof agent is embedded in fibrous inside, wearing and washing the process of textiles, surface one deck mite-proof agent is washed off, new mite-proof agent is had again to supplement from interior stripping, form again the new anti-mite layer of one deck at fabric face, play anti-mite effect, thus embody excellent washability.
Anti-mite modal fiber fabric of the present invention, comfortable and easy to wear, and there is good anti-mite drive mite effect.
