Description
Invention field
The textile material that the field of the invention relates to dipping or is coated with at least a microencapsulated insecticides is fabric, knitted fabric, net materials, mosquito net, lining thing (foil), curtain, WATERPROOF FABRIC or wall material for example, to give insecticide fastness to washing or residual effect and to keep the bioavailability of insecticide, the composition that also relates to the method for preparing described material and be used to handle described material.
Background of invention
In many countries, particularly tropic countries, causing the weak even dead many communicable diseases of humans and animals (for example, malaria, Deng Gere and yellow fever, lymph filariasis and leishmaniasis) is by insect-borne.For example, plasmodium falciparum (Plasmodium falciparum), a kind of mosquito parasite is to cause to surpass 25% children dead reason after neonatal period.Some areas in Africa, by the World Bank (World Bank), having arranged in malaria aspect the permanent disability adjustment years of life lost is first.The development of public health work and the deficiency of funds and drug resistance have hindered many for improving the effort of the medical science aspect that above-mentioned situation done.Recently, research effort has concentrated on the propagated insect of control.
The method of controlling these insects comprises the surface of handling shed and house, and curtain and mosquito net are carried out aerial spraying and impregnation process.Since the 1980s, the net of insecticide treatment and fabric just are developed in the promising means of local characteristic of disease country prevention of malaria as being used for.Use effective and safe pyrethroid at present, for example Permethrin, decis, λ-lambda-cyhalothrin, alphamethrin and cyfloxylate spray in emulsion by textile material being impregnated into insecticide or the dispersion or with described insecticide and handle mosquito net and curtain on the net.
Rest on the mosquito of handling on the material of back and the means of other fly class as killing, the purposes that the pyrethroid insecticide is used for " dipping " mosquito net and curtain is known.This conception is based on following situation, the type of promptly sucking blood arthropod by near the host, can touch the base material that insecticide treatment is crossed when for example the people who sleeps attracts under mosquito net.This method has promoted insect, for example control of mosquito.
So the mosquito net of the washing them during because people are bound to, curtain etc. to a certain extent, are desirable by making these article wash resistant improve the persistence of insecticide on material after the processing.Study verified aspect the disease of preventing the carrier to cause, long-acting insecticide treatment net (LLITNs) is more reliable than traditional net, but this long-acting insecticide treatment net only wash once secondary after must with insecticide handle again or again the dipping.Yet traditional insecticidal mixtures does not provide enough fastnesss to washing, the present invention relates to a kind of way that addresses this problem.
The invention brief introduction
The invention provides fabric that a kind of microencapsulated insecticides handles and with the method for the compositions-treated that comprises microencapsulated insecticides and polymer adhesive, coating or impregnate fabric.Fabric after the described processing even the microencapsulated insecticides that still maintains q.s at fabric face behind cyclic washing to be to kill or repel insects, particularly mosquito.Described fabric can be made into net and clothes etc., to be used to prevent for example malaria of insect-borne disease.A kind of microencapsulated insecticides treatment compositions that contains polymer adhesive and a kind of open-air kit (field kit) that is used to handle fabric also is provided, and described kit comprises first pouch that contains at least a polymer adhesive and second pouch that comprises at least a microencapsulated insecticides.
The explanation of the specific embodiment
Though the present invention all is sensitive to several embodiments of various ways, but hereinafter only describe some specific embodiment in detail, be to be understood that the disclosure only is considered to illustrate of the present invention, and the present invention should be defined in the specific embodiment or the embodiment that is discussed.
Therefore, the invention provides a kind of insecticide treatment composition, it contains at least a polymer adhesive and at least a microencapsulated insecticides.In one embodiment, polymer adhesive and microencapsulated insecticides are to provide together in independent pouch, and are blended together by the terminal user water and form the aqueous treatment composition.In another embodiment, polymer adhesive is ethylene-vinyl acetate (ethylvinylacetate) copolymer.In one embodiment, adhesive is substantially free of polyurethanes, polyurethanes or water miscible polyurethanes after for example disperseing.In further embodiment, insecticide is for example λ-lambda-cyhalothrin of pyrethroid.In another embodiment, insecticide is a for example pirimiphos-methyl of organophosphorus ester.Common bonding of microencapsulated insecticides and polymer adhesive or interaction are to form coating on fabric, described in one embodiment coating is part or discontinuous coating.Fabric is that following dipping or part (discontinuously) apply: textile impregnation is for example comprised in the Aquo-composition of dispersion of at least a microencapsulated insecticides and at least a polymeric binder in treatment compositions, and allow the fabric drying that soaks, need not hot setting.Even after using the washing and rinsing of washing agent for several times, polymer adhesive still bonds or adheres on the fabric and microencapsulated insecticides is also remained adhered on the fabric, and what therefore prolonged fabric kills the insect effect.
Handle fabric with microencapsulated insecticides treatment compositions described herein and reduced insecticide in the washing phase process on the net by the amount of removing after handle.Use the fabric of the compositions-treated that does not contain microencapsulated insecticides and polymer adhesive combination to provide the lasting insect of longer time to knock down and lethal effect with the microencapsulated insecticides of the present invention and the fabric ratio of the compositions-treated of adhesive.Compare with other situation, the wall material of handling with the present composition demonstrates higher remaining insecticidal effect.
The method that provides herein is a simple process, thereby it has been used in combination polymer adhesive and microencapsulated insecticides can be attached on mosquito net and other fabric insecticide.The use of method described herein has produced a kind of product that is better than present obtainable mosquito net, and it provides more lastingly and effectively killed insect active or effect on the surface of net or fabric.Net after the use processing that this paper provided and fabric have caused more effectively public hazards and/or the arthropod that carries disease germs control, and this is relevant with the minimizing transmission of disease.
The fabric of insecticide treatment or dipping can be used to make various terminals and for example use article, but is not limited to net, clothes, mosquito net, curtain and tent.Perhaps, fabric and existing fabric product can use method described herein to handle with insecticidal composition and handle.Insecticide treatment composition of the present invention (Aquo-composition that comprises at least a microencapsulated insecticides and at least a adhesive) is applicable to that also wall is handled and other residual spray is used.In the use of the special net of handling, the product that the textile impregnation of use insecticidal composition or processing method produce is more superior than the performance that existing insecticide dipping, processing or painting method produce, use is simpler and cost is cheaper.And, to compare with some current materials, the material that uses in described method danger when using is lower and can accept more concerning environment.This especially should owing to active component be microencapsulation form and be present in the water-base preparation.When insecticides when for example insecticide is handled by the people described characteristic be particular importance, because it may cause temporaryly itching with the contact skin that exposes in described processing procedure, shouting pain, calcination or numbness, these feel to be known as cacesthesia.Relate to facial cacesthesia and also be called as " subjective facial perception (subjective facialsensation) " or SFS.
Therefore, the invention provides a kind of fabric of handling to give the method for its wash fast insecticidal properties, described method comprises with the fluid composition that kills the insect effective dose handles described fabric, and wherein said fluid composition comprises at least a microcapsules and kills insect active composition and at least a polymer adhesive.In one embodiment, use is the aqueous treatment composition.The line of the fabric of handling is that following coating or part apply, and promptly not only kills with microcapsules that the insect active composition applies but also applies with the polymeric binder of gathering.In one embodiment, part applies and is meant for example discontinuous coating at least one surface of fabric of base material.Those skilled in the art can understand, though coating is discontinuous on micron level for example, but for the base material after the entire process, the adhesive of every square meter of substrate average load and insecticide are in the essentially identical or acceptable statistically index.The effect of polymer adhesive is that the microcapsules " stickup " by will containing insecticide effectively increase microcapsules to each bar line of fabric and kill the adhesion strength of insect material to fabric, thereby provides fastness to washing by this way when keeping the insecticide bioavailability.Though do not wish to be bound by theory, we believe that the interaction between polymer wall, polymer adhesive and the fabric of microcapsules has strengthened the fastness to washing of handling the back fabric.
Therefore the present invention provides weaving or nonwoven fabric material, and the line of described material applies or partly is coated with and is mixed with the sticky polymers binder film that microcapsules kill insecticidal active substance.In one embodiment, the invention provides weaving or nonwoven fabric material, the line of described material scribbles or partly scribbles the insecticidal active substance that kills of polymer adhesive and microcapsules discontinuously.Described fabric can be the form of FURNISHING FABRIC, and for example curtain, bed linen (bed-linen), mosquito net, furniture perhaps can also be sneaked into described fabric in mat, felt rug or other floor or the wall covering.Perhaps described fabric can also be made wrapping form, for example storage or transportation comprise the sack that the material of the food that is subject to the insect pest infringement is used.In addition, by using the described composition that comprises at least a polymer adhesive and at least a microencapsulated insecticides, the flooring material of crossing with described material processed for example carpet or wall material for example wallboard have the insect residual effect control that has increased.
In this respect, in another embodiment, the invention provides a kind of method of in the room, resisting insect pest, it comprises to the wall in described room or floor surface and applies the fluid composition of insect effective dose extremely that described composition contains at least a microcapsules and kills insect active composition and at least a polymer adhesive.
