Definitions

  • the present invention relates to a scatterable agent for dry cleaning textiles, in particular carpets, which contains cellulose powder as an adsorbent.
  • cleaning powders contain, as essential components, surfactants and adsorbents as well as larger amounts of water in loosely bound form. It is assumed that the surfactants, together with the water present, detach the dirt particles from the fibers and transport them to the adsorbent, which is then brushed or suctioned off together with the dirt after the water has been dried.
  • the object of the present invention was therefore to develop a dry cleaning agent for textiles which on the one hand has a high cleaning performance but on the other hand avoids the disadvantages of the known agents.
  • a dry cleaning agent which contains adsorbents, water and organic solvents, is free of zeolite and urea-formaldehyde resin and which contains cellulose powder with a particle size of 1 to 150 ⁇ m as the adsorbent.
  • the agents according to the invention are colorless, dry to slightly moist, easily scatterable powders, which have a high cleaning performance, develop little dust when used and are easy to store. They do not cause graying even when used on dark textiles. It is also noteworthy that the use of surfactants in cleaning agents is greatly reduced and in many cases can be completely avoided.
  • the cellulose powders suitable according to the invention are obtained from commercially available cellulose, which is generally obtained from plant parts, in particular from wood, by comminution with the aid of mechanical and / or chemical processes. Such powders, which are colorless and almost free of lignin and other impurities originating from the plant material, are commercially available in various finenesses, but only the finer qualities with particle sizes of 1 to 150 ⁇ m are suitable for the purposes of the present invention. Agents which are obtained with cellulose powder having a particle size of from 1 to 90 ⁇ m, preferably from 5 to 50 ⁇ m, have particularly high cleaning power.
  • the particle size can be determined using various methods, for example using air jet sieving.
  • the information given in this text is based on measurements with the help of the wet sludge process according to DIN 53 580, which can be carried out with little experimentation according to mental effort and whose results essentially correspond to the air jet sieve process.
  • the origin of the cellulose also influences the quality of the textile cleaning agents made with the powder.
  • Cleaning agents which have been produced with powders from hardwood cellulose, in particular beechwood cellulose, are distinguished by a particularly high cleaning power, with the result that these powders are preferably used in the agents according to the invention.
  • those qualities are particularly preferred which are technically simple, i.e. by mechanical means alone, i.e. be produced by grinding.
  • the proportion of the adsorbent which mainly but preferably consists entirely of cellulose powder, is preferably 35 to 70 percent by weight, in particular 45 to 55 percent by weight, in the agents according to the invention.
  • small amounts of such adsorbents as are known per se for use in dry cleaning agents, for example starch or bentonite, may be present, provided they do not adversely change the properties of the agents.
  • Ground foam glass perlite has proven itself as an additional adsorbent that also functions as a volume generator.
  • the cleaning agents of this invention contain water and certain organic solvents.
  • the amount of these liquids is such that they can still be absorbed by the solid components of the agents, i.e. in particular by the cellulose powder, and thus the scatterability of the agents is ensured.
  • the water content which results from the amount of water added during production and the water already contained in the raw materials, is preferably 25-60, in particular 30-40, percent by weight.
  • Suitable organic solvents are both water-miscible and water-immiscible solvents, provided they do not attack the textiles and are sufficiently volatile to evaporate in the desired time after the agents have been applied to the textiles. When selecting the solvents, it is also important to ensure that they have sufficiently high flash points in the finished product mixture and are toxicologically harmless.
  • Alcohols, ketones, glycol ethers and hydrocarbons, for example isopropanol, acetone, ethers of mono- and diethylene glycol and mono-, di- and tripropylene glycol with boiling points between 120 ° C and 250 ° C and gasolines with a boiling range of 130 - 200 ° are well suited C, as well as mixtures of these solvents.
  • Alcohols with 2 to 3 carbon atoms, propylene glycol ether, gasolines and mixtures thereof are preferably used.
  • the proportion of organic solvents is preferably 5 to 22, in particular 10-15 percent by weight, based on the total cleaning agent.
  • the agents according to the invention can in particular contain surfactants as further constituents. While very good surface cleaning, which is not inferior to the result when using commercially available agents, is achieved even without this additive and the agents surprisingly develop little dust, the removal of fatty stains can be improved even further by adding surfactants.
  • a surfactant addition of up to 4 percent by weight is sufficient; the agents preferably contain 0.05 to 1 percent by weight of surfactants.
  • those substances are particularly suitable which, together with the cellulose powder and possibly other nonvolatile constituents of the compositions, dry to a solid, brittle residue.
  • the surfactants can be selected from the classes of anionic ; and nonionic surfactants, but anionic surfactants are preferably used.
  • Suitable nonionic surfactants for the agents according to the invention are, in particular, addition products of 1 to 30, preferably 4 to 15, moles of ethylene oxide with 1 mole of a compound having 10 to 20 carbon atoms from the group of alcohols, alkylphenols, carboxylic acids and carboxamides.
  • the addition products of ethylene oxide with long-chain primary or secondary alcohols, such as, for example, fatty alcohols or oxo alcohols, and with mono- or dialkylphenols having 6 to 14 carbon atoms in the alkyl groups, are particularly important.
  • Suitable anionic surfactants are in particular those of the sulfate or sulfonate type, but other types such as soaps, long-chain N-acyl sarcosinates, salts of fatty acid cyanamides or salts of ether carboxylic acids, such as those obtained from long-chain alkyl or alkylphenyl polyglycol, can also be used ethers and chloroacetic acid are available can be used.
  • the anionic surfactants are preferably used in the form of the sodium salts.
  • Particularly suitable surfactants of the sulfate type are the sulfuric acid monoesters of long-chain primary alcohols of natural and synthetic origin with 10 to 20 C atoms, ie of fatty alcohols such as, for example, coconut oil alcohols, tallow fatty alcohols, oleyl alcohol, or the C 10 - C 20 oxo alcohols and those of secondary alcohols thereof Chain lengths.
  • the sulfuric acid monoesters of the aliphatic primary alcohols, secondary alcohols or alkylphenols ethoxylated with 1 to 6 mol of ethylene oxide come into consideration.
  • Sulfated fatty acid alkanolamides and sulfated fatty acid monoglycerides are also suitable.
  • the surfactants of the sulfonate type are primarily sulfosuccinic acid monoesters and diesters with 6 to 22 carbon atoms in the alcohol parts, the alkylbenzenesulfonates with Cg - C 15 alkyl groups and the esters of ⁇ -sulfofatty acids, e.g. B. the ⁇ -sulfonated methyl or ethyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
  • Suitable surfactants are ulfonattyp from S the alkane sulfonates obtained from C 12 - 18 are available alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization or by bisulfite addition onto olefins C, and the olefin sulfonates, ie mixtures of alkene and hydroxyalkane sulfonates and Disulfonates as obtained, for example, from long-chain monoolefins with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
  • the fatty alcohol sulfates are particularly preferred from 12 to 18 C-Atonen, the salts of Sulfobernsteinklaonoestern with 15 to 2 0 C-Atonen in the alcohol portion and mixtures of these surfactants used.
  • the agents of this invention can also contain other auxiliaries and additives customary in textile and carpet cleaning agents in a small amount.
  • active ingredients are antistatic components, optical brighteners, substances which reduce re-soiling, additives that improve spreadability and spreadability, preservatives and perfume.
  • antistatic components antistatic components
  • optical brighteners substances which reduce re-soiling
  • additives that improve spreadability and spreadability preservatives and perfume.
  • short textile or cellulose fibers with a length of 2 00 - 100 ⁇ m can be incorporated.
  • no more than 5 percent by weight of auxiliaries and additives are used; the content is preferably not more than 2 percent by weight, based on the total composition.
  • the agents In the preparation of the agents, it proves to be very advantageous that they are composed of only a few components, so that technically simple, mostly one-step processes can be used. Simple mixing apparatuses, such as paddle or drum mixers, are usually used, in which the cellulose powder and, if appropriate, further finely divided solid components are introduced and then sprayed with the liquids which may contain other constituents in solution.
  • Simple mixing apparatuses such as paddle or drum mixers, are usually used, in which the cellulose powder and, if appropriate, further finely divided solid components are introduced and then sprayed with the liquids which may contain other constituents in solution.
  • the agents can be produced in very fine-particle form or in more or less agglomerated form, but the composition always ensures that the agglomerated forms on the textiles easily disintegrate without great mechanical effort. By choosing flaky agglomerates the free-flowing properties of the agents can be dampened up to products which flow with great hesitation, as are preferred for certain applications.
  • the bulk density of the agents can also be influenced to a certain extent in the manufacturing process by choosing more or less compact agglomerates.
  • the agents usually have bulk densities in the range of 200-350 grams per liter, with the result that relatively large volumes are used per unit area. This makes it easier to distribute the product evenly, especially if the products are sprinkled on carpets by hand.
  • the cleaning of the textiles and carpets takes place in such a way that the cleaning agents according to the invention are sprinkled onto the textiles manually or with the aid of a suitable scattering device and then rubbed into the textiles more or less intensively, for example with the aid of a sponge or a brush.
  • training times 0.5 to 2.5 minutes, preferably 0.5 to 1.5 minutes per square meter are chosen.
  • the textiles are allowed to dry until the cleaning agents that combine with the dirt have turned into dry residues. These residues are then removed from the textiles mechanically, for example by brushing or vacuuming.
  • the colorless, hesitantly flowing, but easily scatterable powder had a liter weight of 270 g and could be stored in plastic bags.
  • Example 2 As in Example 1, a cleaning agent was produced which differed from that only in the use of a coarser beech wood cellulose powder (particle size 10-90 ⁇ m).
  • a cleaning agent was prepared which differed from that by using an even coarser beech wood cellulose powder (particle size 10 to 150 gm).
  • Example 1 a cleaning agent was produced which differed from that only in the use of spruce wood cellulose powder (Technocel 50 F).
  • Example 5 As in Example 1, a cleaning agent was produced which, with an otherwise identical composition, contained no surfactant.
  • the cleaning was examined both in a manual and in a mechanical process on carpets, using two commercial agents based on wood flour or urea-formaldehyde resin foam powder and an agent containing zeolite from the prior art for comparison.
  • the application rate was 100 g / m 2 in all cases.
  • test soiling consisting of fat, quartz powder, aluminum oxide, iron oxide and soot, suspended in white spirit, was sprayed evenly onto a beige polyamide velor carpet, rolled in and dried.
  • the cleaning agents were sprinkled on the carpet specimens prepared in this way and immediately worked in for about 60 seconds per square meter using an electrically driven rotating round brush. After drying, which took about 2 hours, the carpets were thoroughly treated (about 1 minute per square meter) with a vacuum cleaner. The cleaning performance was determined optically by measuring the brightening in a reflectance device. Table 1 contains the results in the form of color differences (DE) from the unsoiled carpet.
  • DE color differences
  • test soil was used which was 85 percent by weight of the sieved contents of a vacuum cleaner bag and 15 percent by weight of a standard mixture of kaolin, quartz powder, iron oxide and soot. It was applied to pieces of beige polyamide velor carpet in such a way that carpet and dirt were circulated together in a closed drum with the addition of steel balls until the dirt was evenly distributed.
  • these pieces were sprinkled with cleaning agent (corresponding to 100 g per m 2 ) and then processed manually for about 10 seconds using a medium-hard brush with polypropylene bristles.
  • the dust content of the air at two heights above the carpet was determined gravimetrically with the aid of a dust collector (Gravikon VC 25, collecting time 30 seconds).
  • Table 2 shows the values determined in mg of dust per m 3 of air.
  • compositions according to the invention according to Examples 1 to 5 showed no graying (1), while the composition according to EP 62 536, Example 1, received 2 to 3 points in the evaluation.
