Definitions

  • This invention relates to a method of treating carpets and other textiles made from animal fibres, the method improves resistance to damage caused by insects.
  • Such effluent concentrations of insecticides are undesirable environmentally in that significant concentrations may remain after sewage or other waste treatment. These concentrations may have adverse effects on the population of aquatic insects in waters to which the treated effluent is discharged. This may have an adverse impact on fish species.
  • the problem is particular severe in parts of the U.K. where very strict limits have been set on insecticide levels in effluent. In one particular area (Severn-Trent Water Authority) these controls are so strict that effluent from traditional insect-resist treatment methods cannot meet the levels imposed by the Water Authority at normal textile-mill dilutions.
  • the object of this invention is to provide a method of applying insect-resist agents to animal fibres or products made thereof which minimises the production of liquid effluents thus overcoming environmental problems associated with conventional techniques.
  • insect-resist active compounds are applied to animal fibres (for example wool) or products thereof (for example carpets) using a largely dry technique.
  • the active insect-resist compound is applied to inert particles or incorporated within carrier particles or polymeric particles which are low melt/steam fusible and which are applied evenly over the animal fibres or product thereof.
  • the carrier particles can typically consist of talc, diatomaceous earth, ground corn cob material, chalk or polymeric powders for example polyester, or polyamide or ethylene/vinyl acetate powders preferably with a proportion of its particles less than 7 um in diameter.
  • the active insect-resist compound can be dissolved in a solvent, the carrier particles are then added, the solvent is then evaporated to leave the active ingredient sorbed onto the particles surfaces or within the polymer particles.
  • the active insect-resist compound can be incorporated into the polymer prior to powdering.
  • the treated particles are then spread evenly onto the animal fibres typically by a sprinkling operation which is followed by mechanical agitation of the fibres to improve particle distribution.
  • the invention preferably includes a heat or steaming step in which the fibres or product thereof are heated or steamed for a period of up to 3-4 minutes.
  • This step fuses particles of the polymer type, for example polyamides, to the fibre or to the carpet backing mat.
  • This step markedly improves fastness to subsequent vacuuming, wet or dry-cleaning and light exposure. Steaming also improves fastness of inert non-fusible particles in that it improves the affinity of the particles for the animal fibres.
  • Example 1 The examples are provided as illustrations of the method: Example 1.
  • Talc was treated with permethrin by dissolving the permethrin in petroleum ether, adding the talc and removing the solvent by rotary evaporation to dryness.
  • the talc specification were: median particles size (population distribution) 7.4 ⁇ m median particles size (population distribution) 8.6 urn median particle size (population distribution) 7.1 ⁇ m
  • the permethrin used was 93.7% pure with a 25.75 cis: trans iso er ratio.
  • the permethrin was applied to the talc at a rate of 1.25g/100g of talc.
  • the treated talc was applied to a wool carpet (669 tex, /8th gauge, 8mm pile length, 36 stitches/dm) by sprinkling the treated talc evenly over the carpet pile at a rate of 2% treated talc on weight of pile. This was then brushed to assist penetration of the talc down and into the pile.
  • This example illustrates the beneficial effect of steaming in the transferring of the permethrin to the wool fibres of the carpet. Less than 30% of the permethrin is lost during the three shampooing cycles which is comparable to the loss expected in shampooing carpet insect-resist treated using conventional aqueous exhaustion methods.
  • the carpets were vacuumed and half of each was shampooed as before (3x hot water extraction cleanings). Additionally the shampooed carpets were exposed to an artificial light source to simulate sunlight to assess any loss of permethrin caused by light degradation.
  • the method used was as outlined in International Wool Secretariat Test Method 28 (IWS TM28).
  • the permethrin content of the pile tip, centre and base were analysed for carpet C (12mm pile height). These analyses were repeated for the same carpet sprinkled with a superfine treated talc (90% of particles by mass less than 5 urn and 50% of particle less than 2 um) . The result were;
  • carpet A and C treated with permethrin containing talc were subjected to wear testing consisting of up to 8000 revolutions in a Hexapod carpet wear testing apparatus.
  • the 8000 revolutions ca be taken as representing approximately 4-5 years normal wear in actual use.
  • Permethrin was applied to a fine polyester powder by solvent rotary evaporation as described in Example 1.
  • the powder was a steam fusible type with a melting point of 60°C and particle siz range of 0-80 ⁇ m.
  • the powder was treated to a level of 1.25% permethrin. This was then applied to cut pile and loop pile carpet constructions at the level required to achieve a . treatmen of about 0.22% permethrin owf.
  • the powder was sprinkled onto th sample then brushed in to distribute the powder more evenly through the pile.
  • the carpet samples were then steamed for time ranging from 15 sees to 3 minutes. Representative samples were submitted for bioassaying >i * .h T.bisselliella according to the protocol outlined in IWS TM26.
  • sample A which had been steamed for 3 mins and had a resultant treatment level of 0.014% on pile weight resulted in 100% mortality with 0% mortality in the control.
  • Sample D which had been steamed for 15 sees and had a resultant treatment level of 0.013% permethrin on pile weight produced the same result.
  • Powd in which permethrin was incorporated in the polyester polymer me at a level of 1.25% before the grinding/powdering process gave similar results.

Abstract

On décrit un procédé d'application de composés actifs, résistants aux attaques d'insectes, à des fibres de provenance animale (par exemple de la laine) ou des produits dérivés (par exemple des moquettes) à l'aide d'une technique généralement sèche. Le composé actif résistant aux attaques d'insectes est appliqué à des particules inertes ou incorporé dans des particules porteuses ou des particules polymères qui sont fusibles à la vapeur/à bas point de fusion et qui sont appliquées uniformément sur les fibres animales ou le produit dérivé. Les particules porteuses peuvent typiquement comprendre du talc, de la terre à diatomées, du matériau à base d'épis de maïs broyés, de la craie ou des poudres polymères telles du polyester, ou des poudres de polyamide ou d'acétate d'éthylène/de vinyle, une proportion des particules ayant de préférence un diamètre de moins de 7 νm.
