  • International Patent Application WO 2013/132225 A1 relates to the reintroduction of used polymer particles in the cleaning process after their treatment with detergent dispensed from a cartridge.
  • International patent application WO 2013/132223 A1 discloses that the polymer particles may contain antimicrobial active substance.
  • the polymer particles may have cleaning agents in a form immobilized on the particle surface.
  • Suitable cleaning agents are surfactants, enzymes, oxidants and bleaches. These can be immobilized on the surface of the polymer particles by forming ionic bonds, hydrogen bonds or covalent bonds, and bonding agents such as glutaraldehyde-derived linking groups can also be present between the cleaning agents and the particle surface.
  • washing aids in addition to the indispensable for the washing process ingredients such as surfactants and builder materials usually other ingredients that can be summarized under the term washing aids and the so different drug groups such as foam regulators, graying inhibitors, bleach, bleach activators and color transfer inhibitors include.
  • excipients also include substances whose presence enhances the detergency of surfactants, without them usually having to have a surfactant behavior itself.
  • detergency booster or in the case of a particularly pronounced effect against oil or fat-based stains as a "fat booster".
  • the object of the present invention is to improve the washing performance in the presence of a plurality of polymer particles, in particular in the removal of stains from textile substrates with oily and / or fatty, proteinaceous and / or fruitaceous stains.
  • the invention in a first embodiment is an aqueous wash liquor in a device for the purification of soiled textile substrates, comprising a plurality of water-insoluble solid particles of organic polymeric material carrying on its surface polysaccharide groups.
  • the invention further comprises a process for removing stains from textile substrates, in which a water-containing wash liquor containing a multiplicity of water-insoluble solid particles of organic polymeric material which carry polysaccharide groups on their surface is used.
  • Another object of the invention is the use of a plurality of water-insoluble solid particles of organic polymeric material carrying on its surface polysaccharide groups, for the purification of soiled textile substrates by contacting the particles with the textile substrate in the presence of water.
  • the washing liquor according to the invention can be obtained manually or preferably by machine, for example by means of a washing machine. If desired, it is possible to apply a solid or liquid detergent beforehand, simultaneously or after use with the water-insoluble solid particles. Particularly in the case of simultaneous application, the concentration of such a detergent in the liquid fraction of the wash liquor according to the invention is preferably 1 mg / l to 500 mg / l, in particular 5 mg / l to 100 mg / l.
  • the liquid fraction of the wash liquor is understood to be the proportion of the total wash liquor including the water-insoluble solid particles obtained by centrifuging the water-insoluble solid particles for 5 minutes in a centrifuge by centrifuging 8 kg of the wash liquor containing the solid water-insoluble particles with horizontally mounted cylindrical rotating body of 515 mm inner diameter and 370 mm internal depth at 1400 revolutions per minute separated from the liquid portion.
  • the presence of the polysaccharide groups on the surface of the water-insoluble particles increases the affinity of the particles for water, resulting in improved water uptake and, if surfactant is present, better interaction with surfactants.
  • a further advantage is that the presence of the polysaccharide groups on the surface of the water-insoluble particles leads to an increased adsorption of dirt on the particles, so that overall the cleaning result is improved.
  • the water-insoluble solid particles may comprise any of a variety of different polymers. Particularly preferred are polyalkanes such as polyethylene and polypropylene, polyesters, polyurethanes and / or polyamides including their copolymers. Preferred are polyamide-containing particles and especially particles of polyamide, most especially particles of nylon, most preferably in the form of nylon chips. Various nylon homo- or co-polymers can be used, including nylon 6 and nylon 6,6.

  • Such water-insoluble solid particles form, as it were, the carrier material for the groups on the surface.
  • the water-insoluble particles carry polysaccharide groups on their surface. This can be achieved, for example, by reacting the polymer particles described above with formaldehyde or butylene glycol diglycidyl ether and subsequent reaction with polysaccharide, based on the method described in Journal of Chromatography A, 715 (1995), 49-65.

  • the water-insoluble solid particles or particles or shaped bodies used according to the invention are preferably of such a shape and size which enables good flowability and close contact with the material to be cleaned.
  • Preferred forms of the particles include spheres and cubes, but the preferred particle shape is cylindrical.
  • the particles are preferably sized to each have a weight in the range of from 20 mg to 50 mg, preferably from 30 mg to 40 mg, or at least the number average weight of the particles in these ranges.
  • the preferred particle diameter is 1.5 mm to 6.0 mm, more preferably 2.0 mm to 5.0 mm, most preferably 2.5 mm to 4.5 mm, while the The length of the cylindrical particles is preferably in the range of 2.0 mm to 6.0 mm, more preferably 3.0 mm to 5.0 mm, and most preferably in the range of 4.0 mm.
  • the material to be cleaned is wetted by wetting with water to provide additional enhancement to the wash liquor and thereby improve the transport properties of the laundry and particles within the system such that the removal of Dirt and stains is facilitated.

  • successful results can be achieved with a weight ratio of up to 1:50, although such ratios are not preferred in view of the substantial amounts of wastewater that are generated.
