Definitions

  • the present invention relates to a process for the acaricidal Aus ⁇ armor of materials, in particular of woven or non-woven Tex ⁇ tilien, such as woven goods, knitwear and nonwoven fabric of natural, synthetic or mixed fibers according to the preamble of claim 1.
  • Acaricidal finishing of textiles i. Permanent protection of finished textiles against colonization by house dust mites has been carried out for a long time.
  • the active ingredient conventionally used is mostly permethrin (CAS No. 52645-53-1), a highly effective insecticide used for many applications, e.g. in the ACTIGARD products of SANITIZED, which belongs to the group of synthetic pyrethroids.
  • permethrin CAS No. 52645-53-1
  • ACTIGARD products of SANITIZED which belongs to the group of synthetic pyrethroids.
  • the same effect can also be achieved with other pyrethroids such as deltametrin. Even with the natural pyrethroids, which occur in chrysanthemums, a corresponding effect can be achieved.
  • the textiles described above are usually not only antacid but also provided with agents that resist them Fungi, mold and bacteria.
  • zinc pyrithione is also used. It has now surprisingly been found that this zinc pyrithione (CAS No .: 13463-41-7) has acaricidal properties, which was hitherto unknown.
  • formulations which contain zinc pyrithione alone or in combination with other antimicrobial or acaricidal substances.
  • Zinc-pyrithione-containing formulations o are applied in the after-equipment alone or in combination with other textile chemicals on the textiles to be treated, as below will be described in detail.
  • an action against house dust mites in the concentration range of zinc pyrithione is achieved, which is in the range of 600 and 10'000 ppm, but preferably between 1000 ppm and 6000 ppm, and ideally in the range of 1500 to 3000 ppm.
  • the concentration is based on the dry weight of goods. The optimum concentration depends crucially on the quality of the textile to be finished and the other textile chemicals that are used.
  • formulations containing zinc pyrithione are applied by a conventional method of retrofitting textiles, such as the padding method, the doctor blade method, in particular in the case of coatings, the spraying or foaming method, formulations are used which are preferably between 5 and 60% zinc pyrithione, but preferably a Konzent ⁇ ration between 10 and 50% zinc pyrithione. In addition to zinc pyrithione, such formulations may still contain up to 15% triclosan. Of course, other active ingredients can also be added only in the application bath.
  • This method is particularly recommended when 2-n-octyl-isothiazolin-3-one is to be administered simultaneously with the zinc pyrithione, but also works without problems when formulations containing 1, 2-benzisothiazolin-3-one, quaternary ammonium compounds such as Didecyldimethylammonium chloride, dimethyl-tetradecyl- [3- (trimethoxysilyl) -propyl] -ammonium chloride, or dimethyl-octadecyl- [3- (trimethoxysilyl) -propyl] -ammonium chloride or poly (hexamethylene biguanide) hydrochloride with Formulation be introduced.
  • quaternary ammonium compounds such as Didecyldimethylammonium chloride, dimethyl-tetradecyl- [3- (trimethoxysilyl) -propyl] -ammonium chloride, or dimethyl-octadecy
  • zinc pyrithione is made from a polymer melt, the so-called hot melt process, for example distributed in a polyolefin such as polyethylene or polypropylene or best of all a copolymer such as ethylene-vinyl acetate copolymer (EVA) or in the form of a powder in that the zinc-omadine is mixed with a plastic powder, such as polyurethane, polyethylene, polypropylene or polyvinyl chloride, and powder may be added to a dust removal agent applied to a textile, the zinc pyrithione should be concentrated at a concentration of 2 to 100%, preferably 3 to 35% and ideally 5 to 15% zinc pyrithione alone or in combination with other antimicrobial agents, for example up to 15% triclosan ein ⁇ set.
  • a polyolefin such as polyethylene or polypropylene or best of all a copolymer such as ethylene-vinyl acetate copolymer (EVA)
  • EVA ethylene-vinyl
  • the textile pattern is cut to a size of 8 x 8 cm and placed on a glass plate of the same size. Approximately 50 house dust mites in the adult stage, which were counted under the microscope, were placed in the center of the sample. Of course, the other stages are also present but are not counted. Some food (see method 2) is added. A 5 mm thick rubber plate is placed on the sample, with a 30 mm diameter hole in the middle. This hole is covered at the top with a filter paper, and thereon a metal plate is placed, which also has a hole in the middle, which comes to lie congruently on the hole of the rubber plate. With Klammem the sample plates thus produced are fixed and then 6 resp.
  • the test method according to AFNOR NF G 39-011 as carried out, for example, by TEC Laboratory, F-64600 Anglet, also uses 50 adult house dust mites, Dermatophagoides pteronysinus, which are from a stock culture of INRA, per test sample. Bordeaux and have been grown over several years at 76% humidity at 25 0 C in complete Ab ⁇ absence of insecticides.
  • the mites are fed with a mixture of wheat germ and brown brewer's yeast.
  • the test is carried out at 17 to 23 0 C.
  • the test duration is six weeks and the mites are counted by the heat escape method.
  • the test is carried out as a quadruple determination. The reduction of the mites is determined after six weeks compared to an unequipped control pattern.
  • Formulations containing very few different active ingredients i. For example, with fewer active ingredients than before, get along and despite the textiles against the entire width of microorganisms and additionally protect against the colonization by house dust mites.
  • Fabric for Matratzendrell from a mixture of cotton and Po lyester is with 1, 0%, resp. 1, 2% resp. 1, 5% of a formulation containing 15% zinc pyrithione each equipped with 3 to 5% of acrylate copolymers, dried on the tenter at 12O 0 C for 2 minutes and then tested by method 2 for the effectiveness against mites. All patterns equipped with 1,2 resp. 1.5% of the formulation containing 15% zinc pyrithione no longer show any mites after the test.
  • the samples, which have been equipped with 1.0% of the formulation show on average a MIR (mite inhibiton rate) of 99.3% compared to the non-treated control tissue and thus also a dramatic decrease in the mite population.
  • MIR mite inhibiton rate
  • aqueous formulation containing finely dispersed 48% zinc pyrithione is applied together with a wetting agent and a nonionic surfactant by means of padding process on a cotton fabric and dried for 1 minute at 180 0 C and tested by method 1 for their effectiveness against mites.
  • the patterns show no live mites after the test.
  • a formulation containing 2-n-octyl-isothiazolin-3-one and 1,2-benzisothiazolin-3-one appli ⁇ sheet means padded onto cotton, tested 2 minutes at 120 0 C dried and method 1 for efficacy against mites. The patterns show no live mites after the test.
  • a masterbatch containing 8% zinc pyrithione in EVA was melted together with additional EVA and coated by means of the hot melt process, a process where the fabric to be finished is coated on one side with the plastic melt by means of a roller in such a way that the fabric slides is applied, applied to a mattress.
  • the zinc pyrithione concentration on the finished fabric was 1600 ppm.
  • This tissue was then tested for efficacy against mites by Method 1 (6 weeks). The average reduction in the mite population compared to the baseline value is slightly inconsistent in the range of 30 to 80% in this method, after all, a very significant reduction compared to the non-equipped control pattern with a growth rate of 390% in this test series.
  • a powder containing 24% zinc pyrithione in addition to powdered polyethylene and a petroleum-based de-dusting solution is applied together with EVA to a raw mattress base.
  • a nonwoven is placed and the now embedded EVA with the zinc pyrithione-containing formulation is melted over heated rollers, pressed and cooled again.
  • the Drell produced in this way contains 2100 ppm of zinc pyrithione and is tested for activity against mites by method 1 (6 weeks).
  • the average reduction of the mite population compared to the initial value is inconstant and, above all, different whether the mites are applied to the fleece or to the tissue.
  • With the nonwoven a reduction between 50 and 90% is achieved and on the fabric a reduction between 30 and 70% is achieved.
  • a growth rate of 460% was achieved in this test series.

Abstract

La présente invention concerne l'utilisation de pyrithion de zinc pour l'apprêtage de textiles tissés ou non tissés afin de les protéger contre une infestation par des acariens de poussière. Le pyrithion de zinc est utilisé seul ou combiné à d'autres substances actives, avec ou sans autres produits chimiques textiles. Les préparations contenant du pyrithion de zinc sont appliquées sur les textiles selon des procédés d'apprêtage textile standards, de manière à obtenir une concentration en pyrithion de zinc sur le textile située de préférence entre 1000 et 6000 ppm. Ainsi, sur des textiles plans non revêtus qui sont soumis à un test, on constate une nette réduction de la population d'acariens de poussière, voire même une élimination totale de cette population d'acariens de poussière avec des apprêtages idéaux.
