Definitions

  • This invention relates to treating textiles.
  • the invention relates to treating textiles with insecticides.
  • paper can be treated with dyes and odoriferous agents contained within microcapsules so that these can be released therefrom when the paper is subjected to compression, as when it is struck by a typewriter key hammer, for example, or compressed or abraded by a writing implement.
  • microcapsule has been recently expanded to include microbial cells such as those comprised by fungi, bacteria and algae as disclosed in European Patent Application 0,242,135, which describes adherence of the microcapsules to paper absent a binder or adhesive, although the intended contents for such microcapsules are limited to those classes which are already well known, viz, fragrances, dyes and biocides.
  • microcapsules are limited to those for which prior microcapsules have found applications.
  • Such applications include those where the contents of the microcapsule are released continuously therefrom, as in coating paper to produce perfumed drawer liners, for example; or those applications where use of an article coated with or comprising encapsulated substances, for the purpose intended is destructive of further capacity of the article to provide the desired results.
  • normal use of non-carbon copy paper consumes its capacity for further normal use.
  • the present invention provides novel uses for micro-encapsulation.
  • a method for applying an insecticide to a fibrous textile material characterised by encapsulating the insecticide within microcapsules of a substance which is a food to which insects or their larvae are attracted and attaching the microcapsules to the fibres of the material with a binder which does not impede the release of the insecticide when the microcapsules are devoured.
  • microcapsules may, for example, be a yeast such as Saccharomyces cerivisiae .
  • microcapsules may comprise starch or corn granules, or cellulosic fibres, such as those derived from wood pulp.
  • Said solvent may be ethanol.
  • microcapsules may be bound to cotton in a moist-cure cross-linking process, using, for example, Fixapret CPN.
  • an ethylene grafted vinyl acetate copolymer emulsion such as Vinamul 6705 is used to bind the microcapsules to cotton.
  • a copolymer comprising adipic acid and diethylene triamine partially cross-linked with epichlorohydrin, such as Hercosett may be used as the binder. It will be appreciated, however, that a copolymer of methylmethacrylate and dimethylaminoethylmethacrylate, for example, Dylan GRB, likewise treated with epichlorohydrin may also be used as a binder.
  • Moth proofing agents Mitin FF, Eulan WA and Perigen were dissolved in ethanol, and a dried yeast, Saccharomyces cerevisiae , added thereto. The solvent was evaporated from the resulting suspension, and the yeast cells comprising the thereby encapsulated insecticides were applied, using a spray technique in which the binder was vinamul 6705, to samples of woollen carpets.
  • the Vinamul concentration was approximately 2% by weight of the carpet to which the insecticide containing-yeast cells were added.
  • microencapsulated insecticide is, as a consequence of the method, contained within a micro-capsule and released therefrom in response to moth larvae attempting to devour the wool fibres to which the said micro-capsules are attached.
  • the amount of insecticide applied to the carpet is dependent upon the amount of insecticide encapsulated within the yeast cells, as well as on the number of yeast cells bound to the carpet. It may be preferred to encapsulate a relatively low level of insecticide within the cells but to bind a relatively high number of insecticide containing cells to the carpet. It is thought that moth larvae are attracted to yeast as a nutrient source. Encapsulating a small but fatal dose of biocide in each cell and attaching a large number of cells to the wool fibres will provide the capacity to kill large numbers of larvae without depleting the biocide level too much.
  • binder is such that it does not disguise the nature of the microcapsule so that the moth larvae, for example continue to be attracted to the yeast cells rather than to the fibre, notwithstanding that these are embedded in a binder.
  • Figures 3 to 5 show the insecticide-containing microcapsules 9 bound with Vinamul 6705 ( Figures 3 and 4) or Hercosett 125 (figure 5) to a cotton fibre 10 ( Figure 3), a cotton batt 11 ( Figure 4) or a wool fibre 12 (Figure 5).
  • the method provides that the microcapsule is not necessarily pre-formed, but may be formed in situ within the binder.
  • the amount of binder in which the microcapsules are dispersed may be varied so as to affect the distribution of capsules applied to a particular textile. Moreover, it may be desired to alter the accessibility of said capsules so as to expose greater or lesser regions of these to the event which causes release of the substances contained therein.
  • the invention is not limited to the examples of the binders described herein, and includes many other suitable polymers, such as polyurethanes and derivatives thereof.
