Definitions

  • the invention relates to a washing method for knitwear using defined amounts of ground silicon compounds and cellulases.
  • EP-A2 0307564 a method for creating differently colored areas of textiles made of cellulose by treatment with an aqueous liquor is known which, in addition to cellulases, can contain nonionic surfactants of the fatty alcohol ethoxylate type with up to 20 ethylene oxide units per mole of fatty alcohol .
  • pumice stone is a natural and expensive source of raw materials
  • the stones are ground so strongly after only one use that reuse is no longer an option.
  • part of the pumice stones can also be found in the pockets and must be laboriously removed by hand.
  • Another problem is that only a limited number of textiles can be treated in this way and a not inconsiderable part is so badly damaged by them in this procedure that it is no longer eligible for sale.
  • the object of the invention was therefore to provide a method for treating knitwear which at the same time produces a structural effect and improves the soft feel.
  • the invention relates to a washing process for textiles, in which an aqueous liquor containing wholly or predominantly knitwear with
  • ground silicon compounds preferably ground silicates or ground glass
  • cellulases are not only ideally suited to producing a structural effect on knitwear and thus giving them a "used look", but also due to slight fiber abrasion on the Surface also improve the soft feel and thus the wearing properties noticeably.
  • Knitwear which is also often referred to as knitted fabric, is to be understood as stretchable, textile fabrics which consist of mesh-like loops of thread. They therefore represent a differentiation from the so-called fabrics, which contain threads crossed at right angles.
  • Typical examples of knitwear, on the treatment of which the method according to the invention is directed, are ware goods, such as, for example, stockings, gloves, pullovers and chain goods, such as, for example, jersey and underwear.
  • the knitwear can consist of both vegetable and synthetic fibers. Although cotton fabrics are preferred, lyocell or cellulose fibers, for example, and fiber blends, for example with polyester or polyamide fibers, are also suitable.
  • Silicon dioxide is preferably used as the ground silicon compound, in the simplest case it is sand.
  • ground silicates or ground glass preference is given to using ground silicates or ground glass, the origin of which is not critical.
  • conventional recycling glass is basically just as suitable for the production of the regrind as, for example, expensive glass foam.
  • diatomaceous earth can be considered as a natural source.
  • the silicate starting materials preferably contain no water of crystallization, so that they do not expand at higher temperatures; Perlite, which changes to a pumice stone-like mass at 1200 ° C, is therefore not an option as a starting material, because the same problems associated with pumice stone itself are associated with its use.
  • ground silicates or ground glass which have a grain size in the range from 0.01 to 200 ⁇ m and specifically have a composition in which 40 to 70% by weight of all particles have an average diameter of less than 50 ⁇ m, 40 to 70 wt .-% of 50 to 100 ⁇ m and 20 to 40 wt .-% of greater than 100 ⁇ m - with the proviso that the information is complementary to 100 wt .-%.
  • the millbase is used in amounts of 0.5 to 2.5 and preferably 1.0 to 2.0 kg / kg of the textile fabric used.
  • ground silicon compounds can be carried out according to the methods of the prior art in comminution machines suitable for this purpose, for example crushers, roller mills, grinding media mills or impact mills, as described, for example, in Winnacker-Küchler, Chemische Technologie, Vol. 1, 4th ed. P. 87-93 (1984).
  • Cellulases (1, 4-ß-D-glucan-4-glucanohydrolases; EC 3.2.1.4.) are enzyme complexes that are involved in the breakdown of native cellulose.
  • the acidic cellulases which are preferably to be used as optional component (b) in the sense of the invention are enzymes which are preferably prepared from cultures of Aspergillus or Trichoderma species and have an optimum activity at acidic pH values in the range from 4 to 6 .
  • Acid cellulases which are sold by Novo Nordisk under the Celluzyme® brand and are produced by submerged fermentation of the fungus Humicola insolens, are particularly preferred. Overviews of the interaction of cellulases with cellulose are, for example, from E.Hoshino in J. Biochem.
  • the cellulases are usually used in amounts of 0.1 to 15% by weight, based on the textile fabrics.
  • zeolites can be used as further additives.
  • Zeolites are to be understood as meaning optionally water-containing alkali metal or alkaline earth metal aluminosilicates of the general formula (I)
  • zeolites are the naturally occurring minerals clinoptilolite, erionite or chabasite. However, synthetic zeolites are preferred, for example
  • zeolite NaA and mixtures of zeolite NaA and NaX are preferably used, the proportion of zeolite NaX in such mixtures advantageously being below 30%, in particular below 20%.
  • Suitable zeolites have no particles larger than 30 mm and consist of at least 80% particles smaller than 10 mm. Their average particle size (volume distribution, measurement method: Coulter Counter) is in the range from 1 to 10 mm. Preferred zeolites have an average particle size of 2 to 4 mm.
  • Their calcium binding capacity which is determined according to the information in German patent application DE-AS 24 12 837, is in the range from 100 to 200 mg CaO / g.
  • the zeolites which are usually used in amounts of 1 to 15, preferably 1 to 10,% by weight, based on the textile fabrics, can also contain excess alkali from their production.
  • R 1 is a linear or branched alkyl radical having 12 to 22 carbon atoms and n is a number from 2 to 50 and preferably 5 to 30.
  • Typical examples are addition products of an average of 2 to 50 and in particular 5 to 10 moles of ethylene oxide onto technical fatty alcohols with 12 to 18 carbon atoms such as, for example, dodecanol, isododecanol, coconut oil alcohol, isostearyl alcohol, cetearyl alcohol and / or tallow fatty alcohol.
  • the nonionic surfactants are usually used in amounts of 1 to 15% by weight, preferably 1 to 10% by weight, based on the textile fabrics.
  • buffer salts which can be, for example, alkali and / or alkaline earth metal sulfates, carbonates, phosphates and citrates. Typical examples are sodium sulfate, potassium sulfate, calcium carbonate, sodium phosphate and sodium citrate. Although it is of course not a salt, citric acid can also be used. Polyethylene or polypropylene glycol ethers can also be used as dust binders an average molecular weight in the range of 500 to 5,000.
  • the buffer salts are usually used in amounts of 1 to 10, preferably 1 to 3,% by weight, based on the textile fabrics.
  • the process can also be carried out using compounds of the following composition,
  • the compounds can also be formulated as aqueous gel-like preparations, optionally with the use of polymers, which facilitates their use.
  • the liquor weight ratio of the knitwear to water is preferably in the range from 1:10 to 1:30.
  • a liquor consisting of about 3 to 5 kg of knitwear and 30 to 50 kg of water is prepared, which is firstly treated with 3 to 5 kg of ground silicon compounds, preferably ground glass, and 50 to 100 and preferably 5 to 10 g of cellulase and optionally zeolites, anhydrous nonionic surfactants and / or buffer salts. It is advisable to carry out the process at a pH in the range from 5.0 to 5.5 and at a temperature in the range from 50 to 55 ° C.
  • conventional laundry softeners for example of the esterquat type, can be used together with the preparations.
  • the process according to the invention can also be carried out using the appropriate compounds. Examples
  • Example 1 2.5 kg of differently colored sweaters 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 sweaters were prewashed once at 40 ° C using a conventional heavy-duty detergent containing amylase. The fleet was then made of 1.2 kg of ground glass of the Miltopan® GB type (Pulcra / ES, particle size distribution: 75% ⁇ 50 ⁇ m, 20% 50 to 100 ⁇ m, 5%> 100 ⁇ m) and 100 g of a preparation
  • the sweaters were treated at 50 ° C for 35 min and then rinsed twice. Afterwards, they had a pleasant soft feel and an even texture effect.
  • Example 2 Example 1 was repeated with a product which had a particle size distribution of 75% ⁇ 50 ⁇ m, 20% 50 to 100 ⁇ m and 5%> 100 ⁇ m, and the glass recovered from the first treatment being used for the mechanical treatment of the fabrics was reinstated. After completion of the wash, the sweaters had a soft feel and textured effect like the pattern from Example 1.
  • Example 3 Example 2 was repeated and used for the mechanical treatment of the tissue ground glass, which had already been recovered a total of five times. In addition to the ground glass, a product of the following composition was used:
