Definitions

  • This invention relates to improvements in or relating to an article for removing extraneous dye or dyes from laundry washing applications.
  • WO-A-97/48789 discloses a method for the production of a dye scavenging substrate and its use.
  • the substrate can be added to a laundry wash and the active ingredient therein (an N-trisubstituted ammonium-2-hydroxy-halopropyl compound) causes extraneous dyes in the wash to be preferentially absorbed onto the substrate rather than to other items of clothing in the wash.
  • the invention therefore, provides an article for use in washing textile items in a liquid in, for example, a clothes washing machine, the article comprising a porous substrate material supporting a dye scavenging compound; the substrate material being in the form of a bag or sachet or the like having enclosed therein a substance such as a powder or the like having properties for assisting in appropriate or advantageous treatment of the textile items in the liquid.
  • the substrate material comprises a cellulosic material.
  • the substrate material has incorporated therein a dye-scavenging compound selected from the group consisting of a N-trisubstituted ammonium 2-hydroxy-3-halopropyl compound having the general formula R
  • x is a halogen radical
  • Y is a chloride, bromide, sulphate or sulphonate
  • the Rs are the same or different and are methyl, ethyl, butyl or benzyl groups or an hydroxyl substituted derivative thereof.
  • a preferred compound is glycidly methyl-ammonium chloride (GMAC).
  • the substrate material can comprise a dye scavenging substrate made in accordance with the method disclosed in International Patent Specification No. WO 97/48789.
  • the substrate material can be made into a bag or sachet or the like by folding a suitably sized sheet of the substrate material and securing the sides along their periphery with the substance enclosed therein.
  • the wall of the bag or sachet may consist of two sheets of substrate material secured together about their periphery with the substance enclosed therein.
  • a face of the substrate material may be provided with a polymeric material which face eventually comprises the inner wall of the bag or sachet.
  • the polymeric material may be sprayed onto the face of the substrate or otherwise suitably added or applied to it.
  • the surface area of the substrate material may need to be increased or the composition of the dye scavenging compound as taught in International Patent Specification No. WO 97/48789 may need to be modified. Such modification can be achieved in a variety of techniques.
  • a binder such as a polyvinyl alcohol can be used in the manufacture of the substrate material.
  • the percent binder used (by weight) should be of the order of 12% or less (preferably not less than 10%) so as to provide sufficient sites for the dye scavenging material.
  • the use of a polymeric material provides a number of advantages. Firstly, the presence of the polymeric material on what are effectively opposing faces of the bag or sachet enables the bag to be sealed around the periphery thereof. Secondly, the presence of the polymeric material prevents or substantially reduces the contact between powder in the bag and the dye scavenging compound of the substrate material when the bag or sachet is not in the in use condition in a washing machine. Thirdly, the presence of the polymeric material at least initially enables the bag or sachet to float in the in use condition when the powder in the bag is, for example, an oxygen producing compound such as sodium carbonate peroxyhydrate or sodium carbonate or a combination thereof.
  • the bag or sachet it is desirable that, in making the bag or sachet, certain characteristics are present. Ideally, all of them should be present but this is not essential. These characteristics for the bag or sachet include good sealability, good porosity, good dye pick up, good wash durability and good buoyancy. Good sealability is desirable so that the bag or sachet does not break open or prematurely disintegrate in the washing machine when in use. Good porosity is desired to enable the powder in the bag or sachet to leach out from the bag or sachet in the washing machine when in use. Good wash durability is desirable as the bag or sachet can carry powder of about 3Og and be capable of withstanding wash temperatures of up to 95 0 C. Good buoyancy can improve the effectiveness of the article in use in the washing machine.
  • the substance within the bag or sachet can be selected from appropriate substances which are suitable for assisting in the appropriate or advantageous treatment of the textile items in the wash.
  • the substance could comprise a cleaning agent with or without a binder; a water-softening agent; an enzyme, a brightening agent, a sequestering agent or a surfactant (anionic, non-ionic or cationic) or any combination thereof.
  • a preferred substance is a bleach additive.
  • a bleach additive can be, for example, sodium carbonate peroxyhydrate or sodium carbonate or a combination thereof.
  • a suitable combination is sold under the brand name Oxyper S C B from Solvay Chemicals International SA, Brussels, Belgium.
  • the method for the production of the substrate material may comprise the steps of:-
  • X is a halogen radical
  • Y is a chloride, bromide, sulfate or sulfonate
  • the R's are methyl, ethyl, butyl or benzyl groups or an hydroxyl substituted derivative thereof
  • the substrate material prior to the incorporation of the dye-scavenging chemical preferably comprises pulp (approximately 68% by weight), viscose (approximately 20% by weight) and a binder (approximately 12% by weight).
  • the dye scavenger formulation preferably comprises glycidyl methyl-ammonium chloride (approximately 7.6% by weight), sodium hydroxide (approximately 3.2% by weight) and water (approximately 89.2% by weight).
  • sintering In order to provide the polymeric material on one face of the substrate material, a process known as sintering is used. Sintering does not form a continuous coating thus preserving the porosity of the substrate material. This is required so that the substance enclosed within the bar or sachet can come into contact with the liquid when the bag or sachet is in use.
  • the primary purpose of the polymeric material is to enable the bag or sachet to be sealed.
  • the polymeric material could, if desired, be applied to the periphery of the substrate material for enabling the bag or sachet to be sealed but it has been found from a cost perspective that the sintering technique of applying the polymeric power to the entire face of the substrate material rather than a part of the material is preferred.

  • a hopper is fed with thermoplastic polyethylene powder.
  • the thermoplastic powder is available from Schaetti AG, Birgistrasee 5 CH-8304 Wallisellen and is known as Schaetti Fix powder.
  • the powder can be fed onto a shaker roller which scatters the powder evenly onto the web.
