Abstract

Fabrics, especially furnishing fabrics, the threads of which are coated with a film of a polymeric substance incorporating an insecticidally active substance. The fabrics are particularly useful for making up into articles such as curtains, bed-nets and the like.

Description

FIELD OF THE INVENTION The present invention relates to a process for the application of a desiccant insecticidal agent to fabric resistant to gum. account accounts apply ·

Among the inesecticidal active ingredients for controlling the hippopotamus, pyrethroid materials are relatively common for the ragging of textiles such as carpets, curtains and mosquito nets.

cypermethrin and lembda-citelotrin are mentioned as Mg ₍ which are very stable and potent compounds with potent inasactic activity. Compositions containing pyrethroids (dilution / dilution concentrates) are easily and safely used in the treatment of substances which have tertiary insecticidal activity *

It is well-known * to "impregnate" these mosquito nets and curtains with troid-type insecticide agents to kill mosquitoes and other flying insects on these late materials. This targeting of insecticidal active ingredients is based on: · that hematopoietic arthropods settle on rainwater on relatively large quantities of substances that have an insect-attracting body in their rock salt (for example, a person under mosquito nets). Because these substances are treated with insecticide active substances * the degree of insect control can be increased.

Since mosquito nets and similar fabrics are washed more or less regularly, it is necessary to increase the washing detergent capacity of the tufted downy mildew applied to them. However, by using conventional insecticidal compositions, the active ingredient cannot be applied to a linen wash on charcoal, and it is an object of the present invention to overcome this defect.

The invention thus relates to a process for the washing-resistant application of insecticides on fabrics. according to the invention. and treating the fabric with a liquid composition comprising an effective insecticidal active ingredient and a polymer. During treatment, the fibers of the fabric are coated with noble as an insecticidal active ingredient but also with this polymer. The polymer content of the active ingredient inszektieid & Zo * film is formed of a single strand, which Stick ® .textília inszektieid thereby improving the adhesion strength material hstó _w ε textilis strands. Invention A. · · · ·

- 3 serios are thus formed into woven chemical non-woven fabrics, whereby the filaments are completely ws.y completely covered by an insecticidal active agent, a polymeric film adhering to the filaments, e.g., lexical, such as mosquito net, curtain, bed linen or bed linen. or pedio coverings such as carpets and rugs can be used to treat bagged textiles, such as bags for storage and transportation of insecticidal goods (including live canes), as described in Ulsalssány.

.. the textiles to be treated can be made of natural rosters (such as cotton, roffia, jute, flax, silage, hemp or wool) and synthetic raw materials (such as polyamide, polyester, polypropylene or poly / acrylonitrile); The invention further relates to co-formulations useful for the above treatment.

The compositions of the present invention may be liquid solvent compositions, such as emulsifiable concentrates and oil-in-water emulsions, which may be added after dilution in water, and directly in very small volumes. liquid formulations that may be included.

The compositions of the invention may contain any insecticidal agent effective against insect pests (particularly adult mosquitoes and flies). the root cause (such as propoxur or bendiocarb), organic phosphorus drug (such as mentiont, pyriaiphos-methyl or phenitrothion, pyrethrin or pyrethroid (such as allethrin, bloelletrin, , cyhalothrin or lembda cibrlotrine).

The inventive compositions also contain a polymer dissolved in a liquid solvent in addition to the insecticides. For example, polymeric resins or waxes such as frost, rosin, paraffinic or solls may be used, with Mllak as a polymer being particularly preferred. synthetic pollaors such as polyethylene, polypropylene, ethylene-vinyl acetate polymers, polyastyrene, ester-butadiene copolymers, polybacrylonitrile, scrylonitrile-butadiene-astirol copolymers, poll (vinyl * chloride), ecblylate poly (methyl methacrylate) or polysimides can be used. The molecular weight of the polymer is selected such that the particular polymer is soluble in the solvent of this composition at desired concentration. Polystyrene having an average molecular weight of about 2000 to 1,000,000 is particularly preferred as a synthetic polymer. The average molecular weight of the polymer is usually selected based on the dual requirement that the polymer is readily soluble in the solvent used in the composition, and at the same time significantly enhances the washability of the insecticide applied to this fabric. , it is sometimes advisable to add more than one polymeric material to the formulation. Suitable solvents are all organic liquids in which both the insecticidal active ingredient and the polymer are sufficiently soluble. Solvents include, for example, potassium, such as cyclohxanone, isophorone, acetophenone and methyl isobutyl ketone, ethers, such as anisole, esters, and bexyl. , vegetable oils, timers such as N-sylpyrrolidone, chlorinated hydrocarbons such as 1,1,1-trichloroethane, chlorinated paraffins, chlorine, aromatic hydrocarbons, · · · · ······· ······ ·

5 such as alkylbenzenes and emylphenyltin, aliphatic hydrocarbons, such as alkylcycloparaffinocr, branched-chain Albanians and alcohol ethers such as diethylene glycol mono-methyl ether, propylene glycol-a-one. , polyethylene glycol, and tetrahydrofurfuryl alcohol, and mixtures thereof, and the female compositions are optionally dionic, onionic. non-damp, wet-skidding, emulsifying or non-dispersing cake. Examples of k: thionoo surfactants are: extracellular eau non-ionic compounds, chances are " cetyltriethyl-assium salts ", anionic surfactants are, for example, soaps, aliphatic sulfuric acid eonoester salts (e.g. salts of sulphonated aromatic compounds (such as sodium dodecylbenzene sulphonate, sodium, kiumium or SKmonium-lgnine sulphonate or butyl-naphthalene-sulphonate or dl- and triisopropyl-naphthalene-sulphonate). Examples of nonionic surfactants are: · condensation products of ethylene oxide with xylene alcohols (such as oleyl alcohol or cetyl alcohol) or alkyl phenols (such as oct-11-phenol, nonyl phenols and octylcresol), partial esters of Irish esters and beexite anhydrides, condensation products of the latter partial esters with tritylene oxide; and lecithins · aqueous dispersions v:.-o , _; formulations to be used in emulsions are usually kept in the form of concentrates to be diluted with water prior to use. or in a conventional spray formulation, the compositions generally contain from 1% to 7% by weight, preferably o-50 towg of wedges, of your type. The amount of polymer present in the composition usually ranges from 1 to 25% by weight, preferably from 5 to 1 µg, for other aspects, the compositions of the invention are similar to conventional non-emulsifiable concentrates _{in the form of} emulsifiable concentrates or solutions.

Λ can be applied on both finished and sewn textiles (such as curtains - especially curtain nets on bed linen · furniture covers and the like) and fabrics in production · In the latter case, the treatment according to the invention can be carried out as composition is added to this last treatment bath.

..because the insecticidal active ingredient is dissolved during washing - from the fabric · not only the remaining coating on the fabric becomes less effective · the lubricant also gets into the washing water. Never does this fact mean that there is no danger to the environment in the standard household washing of custom home textiles (such as bedding) * routine washing of treated textiles in a continuous manufacturing plant can already lead to environmental damage. For example, in the manufacture of carpets, insecticidal dye is often applied to the textile larvae for the control of museum insects (Ar.threnus suseorum). .
