Abstract
The invention discloses mosquito repellent fabric which is formed by spinning 60% of bamboo fibers and 40% of cotton fibers in a blending mode. The bamboo fibers are grafted with beta cyclodextrin containing a first aromatic substance, the bamboo fibers and the cotton fibers are adsorbed with a second aromatic substance, the threshold of the first aromatic substance is smaller than or equal to 200 micrograms/kg, the molecular weight of the first aromatic substance is smaller than or equal to 300, and the second aromatic substance adopts terpenic fragrance. According to the mosquito repellent fabric and a preparation method thereof, suitable cyclodextrin is selected to form cavities with suitable sizes to coat the first aromatic substance with a suitable threshold size, and therefore the bamboo fibers which are lasting in aroma releasing rate and capable of releasing the first aromatic substance slowly are obtained; the second aromatic substance is coated through microcapsules and adsorbed on the bamboo fibers through arrangement, due to the fact that the bamboo fibers are provided with apertures with suitable sizes, microcapsule particles can be firmly clamped, and slow aroma releasing can be achieved.
Description
Technical field
The invention belongs to textile material preparation field, be specifically related to a kind of mosquito repellent fabric.
Background technology
All there is the insects such as mosquito, fly, flea all over the world.The World Health Organization advocates soaks article with pesticide, fabric can be made to have desinsection or insect-expelling function, but the mosquito-proof effect of the method can not be lasting.Prior art also adopts arranging process finish fabric, and to reaching lasting mosquito-proof effect, but the method is not washable, and after washing, mosquito-proof effect weakens greatly.
This area needs to develop a kind of fabric with lasting mosquito-proof effect, and the mosquito-proof effect that described fabric still can be remained valid after repeatedly washing.
Summary of the invention
An object of the present invention is to provide a kind of mosquito repellent fabric, and described fabric is formed by the bamboo fibre of 70% and the cotton fiber blending of 30%, and described bamboo fibre grafting beta cyclodextrin, wraps up mosquito-proof medicine in described beta cyclodextrin;

Preferably, citronellal is contained in described mosquito-proof medicine.
The preparation method that two of object of the present invention is to provide the described mosquito repellent fabric of one of a kind of object comprises the steps:
(1) by bamboo fibre grafting beta cyclodextrin;
(2) microwave method embeds mosquito-proof medicine;
(3) air-dry mosquito-proof bamboo fibre;
(4) fabric is obtained with cotton fiber blending;
(5) mosquito-proof medicine micro-capsule dispersion liquid is adopted to arrange.
Preferably, the described method by bamboo fibre grafting beta cyclodextrin of step (1) is: under weak base condition, mixed by epoxychloropropane with bamboo fibre, drop in the alkaline solution of beta cyclodextrin afterwards by mixed liquor, stirs at 40 ~ 50 DEG C.
Preferably, the pH value of described weak base is 8 ~ 9;
Described epoxychloropropane is 0.8 ~ 1.2:0.8 ~ 1.2 with the mixing quality ratio of bamboo fibre;
Described alkaline solution is the sodium hydroxide solution of 20 ~ 30wt%;
In the alkaline solution of described beta cyclodextrin, the concentration of beta cyclodextrin is 50 ~ 70g/L; .
Preferably, the process that described microwave method embeds mosquito-proof medicine is: mosquito-proof medicine is mixed with the solution of 3 ~ 6%, is immersed in described solution by the product of step (1), applies the microwave of 100 ~ 500W, reaction 40 ~ 50min.
Preferably, described air-dry temperature is 20 ~ 35 DEG C.
Preferably, the mosquito-proof medicine micro-capsule dispersion liquid of described employing carries out arrangement and is:
Be embedded in microcapsules by mosquito-proof medicine and obtain the dispersion liquid that concentration is 50 ~ 60w%, be immersed in micro-capsule dispersion liquid by the fabric that step (4) obtains, soaking temperature is 30 ~ 40 DEG C.
Compared with prior art, the present invention has following beneficial effect:
The present invention forms sizeable cavity, the first kind fragrance matter that coated threshold size is suitable by selecting suitable cyclodextrin, thus obtains the bamboo fibre releasing the lasting slow releasing first kind fragrance matter of fragrant speed; The present invention also by microcapsule coated Equations of The Second Kind fragrance matter, and is adsorbed on bamboo fibre by arrangement, because bamboo fibre has sizeable aperture, firmly can block microcapsule granule, realizes slowly releasing perfume (or spice).
So-called mosquito repellent fabric is can the fabric of slow releasing fragrance.
