Definitions

  • This invention relates to a method for surface treating textile and nontextile materials with reactive modified particulate polymers, the use of the reactive modified particulate polymers, and wrinkleproofing, washing, rinsing, refreshing and textile treatment formulations comprising the reactive modified particulate polymers.
  • Cellulosic textiles are given easy care properties by treatment with condensation products of urea, glyoxal and formaldehyde, for example.
  • the finish is applied during the manufacture of textile materials. Softening compounds are frequently further applied with the finish.
  • finished textiles are less wrinkled and creased, easier to iron and softer and smoother after laundering than untreated cellulosics.
  • WO 98/04772 discloses a process for pretreating textile materials by applying a mixture of a polycarboxylic acid and a cationic softener to the textile materials. Wrinkle control is obtained as a result.
  • EP-A 0 978 556 describes a mixture of a softener and a crosslinker component having cationic properties as a fabric wrinkle and crease control composition and also a method of wrinkleproofing textiles.
  • washing, rinsing, cleaning and refreshing processes in aqueous media are customarily carried out in a very dilute liquor, and the ingredients of the particular formulation used generally do not remain on the substrate, but are disposed of with the effluent. Sustained modification of the surface of cellulosic materials with dispersed particles in the hereinbelow mentioned processes is accomplished only to an unsatisfactory degree.
  • U.S. Pat. No. 5,476,660 discloses the principle of using polymeric retention aids for cationic or zwitterionic dispersions of polystyrene or wax that contain the active substance embedded in the dispersed particles. These dispersed particles act as carrier particles, since they adhere to the treated surface where they release an active substance, for example in the case of use in surfactant formulations.
  • U.S. Pat. No. 3,993,830 discloses applying a non-permanent soil-release finish to a textile material by treating the textile material with a dilute aqueous solution comprising a polycarboxylate and a water-soluble salt of a polyvalent metal.
  • Preferred polycarboxylates are said to be water-soluble copolymers of ethylenically unsaturated monocarboxylic acids and alkyl acrylates. The mixtures are released in the rinse cycle of a home laundry process.
  • the invention further provides for the use of the reactive modified particulate polymers as surface-modifying ingredient in rinsing, refreshing or washing compositions and also laundry detergent, refreshing and textile treatment formulations comprising the particulate polymers.
  • Reactive modified polymers for the purposes of the invention are particulate polymers containing reactive, crosslinking groups.
  • the reactive modified polymers may contain units derived from anionic and/or cationic monomers and may have anionic, cationic or amphoteric protective colloids or emulsifiers at their surface.
  • the reactive modified polymers may contain units derived from monomers containing reactive groups and/or may have at their surface protective colloids or emulsifiers that contain reactive groups.
  • Reactive modified polymers of anionic character i.e., which contain anionic groups and/or are dispersed using anionic protective colloids or emulsifiers, may have a coating with cationic polymers at their surface.
  • the reactive groups may also have a postcrosslinking effect, i.e., develop their crosslinking effect only on heating or drying of the treated textile surfaces.
  • the reactive modified particulate polymers are obtainable by copolymerization of ethylenically unsaturated monomers containing no crosslinking reactive groups with ethylenically unsaturated monomers which do contain such crosslinking reactive groups. But the reactive groups may also be introduced into the polymer by coating the surfaces of the polymer particles with colloids having crosslinking reactive groups.
  • the reactive modified polymers used according to the invention are in one embodiment of the invention obtainable by copolymerizing ethylenically unsaturated monomers containing no reactive groups with ethylenically unsaturated monomers containing reactive groups.
  • Useful monomers containing no reactive groups include for example alkyl esters of C 3 -C 5 monoethylenically unsaturated carboxylic acids with monohydric C 1 -C 22 alcohols, hydroxyalkyl esters of C 3 -C 5 monoethylenically unsaturated carboxylic acids with dihydric C 2 -C 4 alcohols, vinyl esters of saturated C 1 -C 18 carboxylic acids, ethylene, propylene, isobutylene, C 4 -C 24 alpha-olefins, butadiene, styrene, alpha-methylstyrene, acrylonitrile, methacrylonitrile, tetrafluoroethylene, vinylidene fluoride, fluoroethylene, chlorotrifluoroethylene, hexafluoropropene or mixtures thereof.
  • Preferred monomers are methyl acrylate, ethyl acrylate, n-butyl acrylate, sec-butyl acrylate, tert-butyl acrylate, ethylhexyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, methyl methacrylate, n-butyl methacrylate, vinyl acetate, vinyl propionate, styrene, ethylene, propylene, butylene, isobutene, diisobutene and tetrafluoroethylene, and particularly preferred monomers are methyl acrylate, ethyl acrylate, n-butyl acrylate, styrene, methyl methacrylate and vinyl acetate.
  • Useful reactive, crosslinking groups include for example azetidinium, glycidyl ether, halohydrin, carboxylic anhydride, carbonyl chloride, isocyanate, vinyl sulfone, N-methylol, aldehyde and imine groups.
  • Preferred unsaturated monomers containing reactive groups are N-methylol(meth)acrylamide, glycidyl methacrylate, methacryloyloxypropyltrimethylsilane, vinyltrimethoxysilane, m-isopropenylbenzyl isocyanate, acrolein, isobutoxymethylacrylamide, isobutoxymethylacrylamide, hydroxymethylated diacetoneacrylamide, allyl N-methylolcarbamate, N-formyl-N′-acryloyloxymethylenediamine, gamma-methylacryloyloxypropyltrimethoxysilane, methacryloyloxyethoxytrimethylsilane, epithiopropyl methacrylate, vinyl chloride, 2-chloroethyl acrylate, 4-chlorobutyl acrylate, 3-chloro-2-hydroxypropyl acrylate, methyl 1-(chloromethyl)acrylate, 2-(bromomethyl)acrylon
  • the reactive modified polymers used according to the invention may be prepared by the conventional methods of solution, precipitation, suspension or emulsion polymerization described for example in P. Lovell and M. S. El-Aasser, Emulsion Polymerisation and Emulsion Polymers, Wiley, New York, 1997.
  • the reactive modified particulate polymers used according to the invention are obtained by emulsion polymerization in an aqueous medium.
  • the polymerization is conducted in the presence of polymerization initiators that decompose either thermally or photochemically or in the presence of redox initiators.
  • polymerization initiators that decompose thermally preference is given to those which decompose in the range from 20 to 180° C., especially from 50 to 90° C.
  • Preferred polymerization initiators for the emulsion polymerization are water-soluble organic peroxides such as peresters, percarbonates, perketals, hydroperoxides, inorganic peroxides such as H 2 O 2 , salts of peroxosulfuric acid and peroxodisulfuric acid, azo compounds, boron-alkyl compounds and also hydrocarbons that decompose homolytically.
  • water-soluble organic peroxides such as peresters, percarbonates, perketals, hydroperoxides, inorganic peroxides such as H 2 O 2 , salts of peroxosulfuric acid and peroxodisulfuric acid, azo compounds, boron-alkyl compounds and also hydrocarbons that decompose homolytically.
  • the polymerization initiators which are used in amounts in the range from 0.01 to 15% by weight, based on the monomers, can be used individually or in combination.
  • An emulsion polymerization to prepare the polymers is generally carried out using dispersing assistants.
  • Useful dispersing assistants include water-soluble macromolecular organic compounds having polar groups, such as polyvinylpyrrolidone, copolymers of vinyl propionate or acetate and vinylpyrrolidone, partially hydrolyzed copolymers of an acrylic ester, and acrylonitrile, polyvinyl alcohols having different residual acetate contents, cellulose ethers, gelatin, block copolymers, modified starch, low molecular weight carboxyl- and/or sulfo-containing polymers or mixtures thereof.
  • Useful natural protective colloids include water-soluble proteins, partially degraded proteins, water-soluble cellulose ethers, native starches, degraded starches and/or chemically modified starches.
  • water-soluble cellulose esters are hydroxyethylcellulose and methylcellulose.
  • Useful natural starches include those obtainable by heating in an aqueous medium to above the gelatinization temperature. It is also possible to use degraded starches that are obtainable by hydrolytic, oxidative or enzymatic degradation.
  • Particularly preferred protective colloids are polyvinyl alcohols having a residual acetate content from 0 to 39, especially from 5 to 39, mol % and vinylpyrrolidone/vinyl propionate copolymers having a vinyl ester content of up to 35%, especially from 5 to 30%, by weight.
  • Useful dispersing assistants further include nonionic or ionic emulsifiers and also mixtures thereof.
