Definitions

• the present invention relates to a carpet cleaner based on cellulose and a process too its manufacture.
• carpet cleaners will in the chemical industry, especially in the textile industry and also used in the cleaning industry.
• liquid or solid detergents are also used.
• the firm Detergents are called dry cleaners referred to and usually consist of a fixed, more or less powdery matrix with different Cleaning fluids is soaked. This powdery matrix is on the one to be cleaned Surface applied, the cleaning liquid in the matrix in conjunction with that usually it contains the dirt on the dirt to be cleaned Area dissolves. After the evaporation of the in the matrix also contains solvent the dirt with the surfactant is absorbed in the matrix. The cleaning of the carpet is then easier Way by brushing or vacuuming the matrix material along with the dirt.
• matrix material are a variety of substances are known, such as inorganic materials, e.g.
• synthetic Polymers e.g. Urea-formaldehyde resins, ground Polyurethane foam, polyethylene powder, polystyrene powder, etc., as well as natural polymers.
• Natural polymers Cellulose base, e.g. Sawdust, wood flour, bark flour or cellulose powder.
• a disadvantage of the lignin-containing cellulose products is their natural brown color. Therefore, in the DE 34 37 629 proposed as pure adsorbent Cellulose powder with particle sizes between 1 and 150 ⁇ m to be used by grinding hardwood pulp be won. Own these powders now, however, the disadvantage that on the one hand they only very low porosity and consequently only one low absorption capacity for the actual cleaning liquid own and secondly due to their very small particle size is difficult handle and even incomplete of most carpets have it removed.
• DE 44 11 047 therefore proposes the actual one powdery adsorbent additionally rollable particles with dimensions between 1 and 50 mm. These particles can be made from a porous sponge-like Material, such as a viscose sponge, consist. This admixture did the mechanical stress on the carpet fibers is reduced and at the same time removing lint relieved, but the required amount of solids over 40 mass% and thus represents a significant ecological and economic burden. Furthermore are the problems of removing the dusty cellulose products and too low Fluid intake has not been resolved.
• DE 44 07 906 C1 describes a process for the production known from cellulose carbamate. Farther is a cleaning agent for in DE 40 07 522 A1 Carpet described, which consists of molded bodies from regenerated Cellulose consists.
• the object of the present invention is therefore a Carpet cleaner and a process for its manufacture to provide that not just one high absorption capacity for the cleaning liquids but also has one on the one used Cellulose-based high cleaning performance.
• a rational and environmentally friendly Manufacturing process provided become. This job is done by the carpet cleaner according to claim 1 and the method according to Claim 14 solved.
• Advantageous further developments of the carpet cleaner according to the invention and the carpet cleaner according to the invention Procedures are set out in the dependent claims given.
• the carpet cleaner consists of cellulose particles, which a cleaning liquid and Contain surfactants, whereby the cellulose particles by Coagulation of an alkaline solution known per se of cellulose carbamate and then washing out and crushing the cellulose gel can be obtained.
• the carbamate groups during coagulation of the cellulose carbamate solution is not complete split off, but 0.001 to 0.3 remain Carbamate groups per anhydroglucose unit of cellulose in the product.
• gel particles produced in this way can advantageously be used other hydrophilic polymers, in particular Polysaccharides, e.g. Starch or guar flour, polysaccharide derivatives, such as. Carboxymethyl cellulose, Carboxymethyl starch or starch phosphate, or synthetic, ionic or nonionic polymers, such as e.g. Polyacrylic acid derivatives, polystyrene sulfonate, polyvinyl alcohol or immobilized polyvinyl pyrrolidone Form included. These additional quantities can be in wide limits, but should be 20 Do not exceed mass% based on cellulose.
• Polysaccharides e.g. Starch or guar flour
• polysaccharide derivatives such as. Carboxymethyl cellulose, Carboxymethyl starch or starch phosphate
• synthetic, ionic or nonionic polymers such as e.g. Polyacrylic acid derivatives, polystyrene sulfonate, polyvinyl alcohol or immobil
• the preferred particle sizes for the swollen ones Gel particles are in the range of 0.1 to 5 mm the water retention capacity (that contained in the gel Amount of water in% based on the dried gel) Gel particles according to the invention should advantageously be at least 400%.
• the cleaning liquid is introduced into the cellulose particles according to the invention in a simple manner by suspending the gel particles which are still water-containing from the manufacturing process of the particles in a mixture of water, a C 2 -C 4 -alkanol, -alkanediol or -triol alone or in mixtures with an aliphatic solvent, a surfactant and optionally fragrances until the concentration is approximately equalized.
• the excess liquid is then centrifuged or suctioned off and the finished carpet cleaner can be filled into an airtight container or bag.
• the centrifuged or suctioned-off liquid can then be concentrated again by adding the non-aqueous components and used again.
• Surfactants are used for cleaning carpets conventionally known and proven anionic, nonionic and / or amphoteric surfactants used.
• the carpets or textile and floor coverings are cleaned with the carpet cleaner according to the invention by manual or mechanical sprinkling of the cleaner onto the textile or the floor covering and subsequent incorporation into the soiled surfaces. After the majority of the cleaning liquid has evaporated, the cellulose particles, which are now very shrunk and contain the dirt, are suctioned off again. Depending on the degree of soiling, 50 to 200 g of the carpet cleaner according to the invention are used per m 2 . If necessary, the cleaning step is repeated until the desired cleaning effect is achieved.
• the resulting cellulose gel particles which after the Centrifuging a cellulose content of 16.5 mass% had (corresponding to a water retention capacity of 506%), were mixed with a mixture of 2 kg of 2-propanol and 50 g of a commercially available dishwashing detergent, the 30% anionic, 10% nonionic and Contained ⁇ 5% amphoteric surfactants and a fragrance, mixed and centrifuged again.
• the cleaning performance was tested in such a way that half of a carpet covering, heavily contaminated with street dirt and a dried tea stain, was sprinkled with about 100 g of carpet cleaner per m 2 . This was then worked in with a brush and removed after drying with a hand vacuum cleaner. The visual assessment of the treated and the untreated as well as an unused area showed that the tea stain had been completely removed and the normal soiled items after the treatment could not be distinguished from the unused one. No edge formation was observed on the cleaned surface.
• the resulting cellulose gel particles which after the Centrifuging a solids content of 13 mass% had (corresponding to a water retention capacity of 669%), were mixed with a mixture of 2 kg of 2-propanol, 500 g of glycerin and 50 g of a commercially available Dishwashing detergent, the 30% anionic, 10% non-ionic and ⁇ 5% amphoteric surfactants and one Contained fragrance, mixed and centrifuged again.
• Cellulose gel particles were produced analogously to Example 2, with a mixture of 1.5 kg 2-propanol, 1 kg of petroleum spirit (bp .: 150 - 190 ° C) and 50 g of one commercially available dishwashing detergent, which is 30% anionic, 10% non-ionic and ⁇ 5% amphoteric Contained, mixed and surfactants and a fragrance sucked off on a frit.
• Example 2 There was about 2.5 kg of a light particulate product received, the cleaning performance as in Example 2 was assessed. The visual assessment of the treated and untreated areas also a clear cleaning effect. After a second treatment there were hardly any differences between the dirty and cleaned as well as the to recognize untreated carpet spots.
