Definitions

  • This invention relates to treating materials, for example, textiles.
  • the invention relates to treating textiles with flame retardants, biocides, insecticides, odoriferous agents and dyes.
  • 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 applica ⁇ tions 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. Thus, for example, 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 substances to materials comprising encapsulating the substances within micro ⁇ capsules from which the substances can be released either by lesion of the microcapsules or by leaching of the substances therefrom and attaching the microcapsules to the materials with a binder which secures the micro ⁇ capsules substantially against removal from the material during normal usage of the material but does not impede the release of the substances.
  • the microcapsules may, for example, be a yeast such as Saccharomvces cerivisiae.
  • microcapsules may comprise starch or corn granules, or cellulosic fibres, such as those derived from wood pulp.
  • the substances may be alkali-soluble biocides, odoriferous agents such as mint, clove or cedar wood oils, for example, dyes, or indeed any other appropriate material capable of being encapsulated by known means into said microcapsules.
  • Encapsulation of the aforementioned oils may be achieved by suspending dried yeast in a solution comprising an organic solvent and an oil and evaporating said solvent so that the oils enter by diffusion.
  • oils may be added to said solvent, and the method according to the invention includes any suitable organic solvent-soluble substance or subtances, in addition to the the aforesaid oils.
  • Said solvent may be ethanol. Where the substance is alkali soluble, it may be precipitated with acid within the microcapsule.
  • Said substance may, for example, be an organo- sulphur compound when it may be generally desired that it is not continuously released from the microcapsules but is released in response to a specific event.
  • 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 " .
  • a copolymer of methylmethacrylate and dimethylamino- ethylmethacrylate, for example, Dylan GRB, likewise treated with epichlorohydrin may also be used as a binder.
  • Figure 1 shows schematically the precipitation of an alkali soluble biocide within yeast cells to yield a microcapsule containing biocide, prior to the application thereof, for example, to a woollen carpet;
  • Figure 2 likewise shows the microencapsulation of an organic solvent-soluble biocide within yeast cells to yield micro ⁇ capsules containing biocide prior to the application thereof to textiles;
  • Figure 3 is from a scanning electron micrograph of cotton fabric with yeast bound by Vinamul 6705 thereto;
  • Figure 4 is from a scanning electron micrograph of a cotton wool batt with yeast bound by Vinamul thereto;
  • Figure 5 is from a scanning electron micrograph of a wool fibre with yeast bound thereto by Hercosett 125.
  • the present invention provides a method for applying substances to materials comprising encapsulating the substances within microcapsules from which the substances can be released either by lesion of the microcapsules or by leaching of the substances therefrom and attaching the microcapsules to the materials with a binder which secures the microcapsules substantially against removal from the material during normal usage of the material but does not impede the release of the substances.
  • Moth proofing agents Mitin FF, Eulan WA and Perigen were dissolved in ethanol, and a dried yeast, Saccharomvces cerrevisiae, 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.
  • the icroencapsulated 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.
  • Thiol containing compounds which produce distinct odours when heated above temperatures encountered during processing and subsequent use can be encapsulated into an inert impervious polymer sheath during the production thereof, and subsequently incorporated into textiles, foams and plastics to act as a sensory early warning agent to indicate a possible conflagration.
  • Vinamul 6705 or the "softer" variants such as Vinacryl 43309 and Vinacryl 43289 may comprise the polymer sheath.
  • 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.
  • binders must be treated having regard to the nature of the capsules dispersed therein, so that, for example, treatments which are not detrimental to the binder but which are harmful to the microcapsules and/or contents thereof and vice versa are not used.
  • 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.
  • a polymer which when polymerised comprises pores so that volatile substances encapsulated in microcapsules which are completely submerged within the binder are still able to permeate to the environment.

Abstract

Des substances, insecticides, teintures ou parfums, sont encapsulées dans des microcapsules de levure, par exemple, et fixées à des textiles tels que le coton ou la laine, à l'aide d'un liant qui n'empêche pas la substance d'être libérée de la microcapsule.
