Definitions

  • the invention relates to solid preparations with a defined content of acidic cellulases, selected Fatty alcohol polyglycol ether and buffer salts, a process for producing a "stonewash” - Effect on dyed cotton fabric using the preparations mentioned and their Use as a means of producing dyed cotton fabrics with a "stonewash” effect.
  • EP-A2 0307564 and EP-A1 0665324 Ecolab
  • processes for creating differently colored areas of textiles made of cellulose by treatment with an aqueous liquor which, in addition to cellulases, contain nonionic surfactants of the fatty alcohol ethoxylate type with up to 20 ethylene oxide units can contain per mole of fatty alcohol.
  • Cellulases (1,4- ⁇ -D-glucan-4-glucanohydrolases; EC 3.2.1.4.) are enzyme complexes that are involved in the breakdown of native cellulose.
  • the acidic cellulases to be used according to the invention are enzymes which are preferably prepared from cultures of Aspergillus or Trichoderma species and which have an optimum activity at acidic pH values in the range from 4 to 6. Acidic cellulases, which are sold by Novo Nordisk under the Celluzyme® brand and are produced by submerged fermentation of the Humicola insolens fungus, are particularly preferred. Overviews of the interaction of cellulases with cellulose are, for example, from E.Hoshino in J. Biochem. 114 , 230; 236 (1994), ibid. 115 , 837 (1994) and J. Ferment. Bioeng. 77 , 496 (1994) .
  • Fatty alcohol polyglycol ethers are known nonionic surfactants which are obtained on an industrial scale by alkoxylating fatty alcohols with ethylene oxide and / or propylene oxide in the presence of homogeneous or heterogeneous alkaline catalysts. With regard to the parameters of enzyme stabilization, activity and dust-binding capacity, the selection of these components has proven to be critical. Fatty alcohol polyglycol ethers which form component (b) and which are to be used particularly advantageously therefore follow the formula (I) in which R 1 is a linear alkyl radical having 16 to 22 carbon atoms and n is preferably a number from 50 to 80. Typical examples are addition products of an average of 40 to 100 and in particular 50 to 60 moles of ethylene oxide in technical terms tallow fatty alcohols with 16 to 18 carbon atoms.
  • the choice of the inorganic or organic salts is in itself not very critical. In terms of stabilization the cellulases and the dust-binding capacity, however, have alkali and / or alkaline earth sulfates, -carbonates, -phosphates and -citrates especially proven. Typical examples are sodium sulfate, Potassium sulfate, calcium carbonate, sodium phosphate and sodium citrate. Although it goes without saying citric acid can also be considered.
  • the preparations according to the invention are used in amounts of customary 0.1 to 10 and preferably 1 to 5 wt .-% - based on the cotton fabric - used.
  • the liquor weight ratio of cotton fabric to water is usually in the range of 1: 10 to 1: 100.
  • a fleet consisting of about 3 to 5 kg of denim and 50 to 80 is preferred kg of water is prepared, which is 30 to 200 and preferably 50 to 100 g of the preparations according to the invention adds. It is recommended to use the procedure at a pH in the range of 4.5 to 5.5 and at a temperature in the range of 50 to 65, preferably 55 to 60 ° C. If If desired, conventional fabric softener can be used together with the preparations.
  • the preparations according to the invention impart colored cotton fabrics, in particular blue ones Denim not only a typical "stonewash” effect, but also a pleasant soft touch, she thus also improve comfort.
  • Another object of the invention therefore relates the use of the solid preparations according to the invention to achieve a "stonewash" effect on dyed cotton fabric.
  • Example 1 A pair of brand-new blue jeans were placed in a Siemens Siewamat 3573 washing machine with a capacity of 5.5 kg of laundry and about 60 l of water. The jeans were prewashed once at 40 ° C with a conventional detergent containing amylase. 50 g of a preparation consisting of: 15% by weight of Celluzyme, 15% by weight tallow fatty alcohol + 50 EO and 70% by weight sodium citrate / citric acid (1: 1) added. The dust development during filling was assessed as “dust-free” (+) or “not dust-free” (-). The liquor was treated at 55 ° C. for 60 min and then rinsed clear twice. The "stonewash" effect and the soft feel were assessed subjectively by a panel consisting of 6 trained people on a scale from 1 (very clear or very soft) to 6 (hardly noticeable or hard). The result is summarized in Table 1.
  • Example 1 was repeated, but instead of the tallow fatty alcohol + 50 EO a tallow fatty alcohol + 20EO was used and the treatment was carried out over a period of 60 min at a temperature of 55 ° C. The results are summarized in Table 1.
  • Comparative example V2 Comparative example V2. Comparative example V1 was repeated, but the treatment was carried out over a period of 90 minutes, not over a period of 60 minutes. The results are summarized in Table 1.
  • Comparative Example V3 Comparative Example V3. Comparative example V2 was repeated, but the treatment was carried out not at a temperature of 55, but 40 ° C. The results are summarized in Table 1
  • the example and the comparative examples show that only when the preparations according to the invention are used dyed cotton fabrics are obtained, which are characterized both by an optimal "stonewash” effect as well as a pleasant soft feel.
  • the preparations according to the invention are practical when decanting dust free.
