Definitions

• the filter powder and components of the dry-cleaning bath are added to the bath as a single additive in solid form, containing 108S% by weight of adsorbent, 70% by weight of detergent, 5- 80% by weight of water, and 5-40% by weight of a finish for improving the hand of the dry-cleaned textile products, and more preferably 30-40% by weight of adsorbent, 15-17% by weight of detergent, 3842% by Weight of water, and 816% by weight of finish.
• solvents such as hydrocarbons, and preferably halogenated hydrocarbons, in particular perchloroethylene and trichloroethylene.
• cleaning enhancers can be added to the solvents.
• These cleaning enhancers are in general liquid products containing detergents and, if necessary, solvents, such as halogenated hydrocarbons.
• the dry-cleaning bath In addition to the detergent and water, the dry-cleaning bath generally contains a finsh for improving the hand of the cleaned textile products, which finish is usually added separately to the solvent.
• the bath may also contain other substances, e.g. other textile aids, such as antistatic agents, which are usually added separately to the solvent.
• other textile aids such as antistatic agents
• Dry cleaning as a rule is carried out in an apparatus consisting of a vessel with a recycle line containing a filter on which a filter aid, such as diatomaceous earth, is present.
• the apparatus comprises a built-in water-measuring device and separate tanks for different auxiliary agents.
• the solvent is introduced into the vessel and the filter aid added to the solvent to coat the filter.
• the apparatus is filled with clothes. After this, the water, the liquid cleaning enhancer, the finish, and any other auxiliary agents that may be desired are measured and added.
• An object of the present invention is the provision of compositions useful in dry cleaning, which contain all additives generally used in a dry-cleaning bath.
• a further object of the present invention is the provision of solid compositions useful in dry cleaning, which are ice easier and more accurate to measure than the liquid additives.
• a still further object of the present invention is the provision of a simple method of preparing dry-cleaning baths eliminating errors by unskilled labor.
• the solid compositions of the present invention which contain at least a solid adsorbent in finely divided form, a detergent, water, and a finish for improving the hand of the dry-cleaned textile products.
• compositions may also contain other substances, e.g. solvents, dissolving agents, antistatic agents, optical bleaching agents, chemical bleaching agents, such as peroxides and sodium hydrosulfite, special stain-removing agents, such as cyclohexanone, lactic acid, and oxalic acid, hydrophobing agents, fire retardants, preservatives, bactericides, fungicides, insecticides, perfumes, etc.
• sweeteners that is, acid-binding substances, which prevent the bath from becoming acidic during the dry-cleaning treatment, e.g. lime.
• compositions may contain all the additives simultaneously, measuring is simplified. Moreover, measuring can be eifected more accurately.
• the adsorbents serve to coat the filter, which may contain in addition to the adsorbents of the composition, also additional filter aids.
• the solid compositions preferably contain about 10-85% by weight of adsorbent 5-70% by weight of detergent 5-80% by Weight of water, and
• solid compositions containing about 3040% by weight of adsorbent 1517% by weight of detergent 38-42% by Weight of Water, and
• the solid-compositions are added to the solvents in different quantities depending upon the material to be cleaned.
• the quantity is preferably 1 to 10 parts by Weight to 1000 parts by weight of solvent.
• Any adsorbent known in the art may be used.
• adsorbents which may be used in the compositions according to the invention are diatomaceous earth, silica, alumina, metal silicates, ground or fibrous asbestos, metal stearates, sawdust, cellulose powder, starch, powdered synthetic polymers, cellulose fibers, etc.
• detergents which may be used in the compositions according to the invention are neutralized fatty acids, petroleum snlfonates, fatty alcohol sulfates, condensates of fatty acids, alkylaryl snlfonates, secondary alkyl sulfates, epoxyethane condensates, sulfuric acid esters of polyethylene-glycol compounds, quaternary ammonium compounds, etc.
• Examples of finishes for improving the hand of the drycleaned textile products which may be, used in the compositions according to the invention are terpene resins,
• urea formaldehyde resins paraffin, polyglycols, lanolin, stearin, petroleum resins, alkyd resins, gum resins, waxes, etc. Parafiin and pico-pale resins are to be preferred.
• Dry-cleaning compositions which contain, besides a detergent, an aggregating agent.
• the quantity of solid aggregating agent used, however, is relatively small. These known compositions therefore are not solid, but pasty. Moreover they do not contain any dressings.
• a solid powdery composition is obtained.
• a solid powdery composition is obtained.
• EXAMPLE III For the preparation of a composition containing an adsorbent, a detergent, water, a finish for improving the hand of the dry-cleaned products, and an antistatic agent, the following components are mixed:
• a solid powdery composition is obtained.
• EXAMPLE IV 250 g. of the composition prepared according to Example I are introduced into an apparatus for dry cleaning containing 400 l. of gasoline. Subsequently 25 kg. of woolen knitwear to be cleaned are introduced into the apparatus. Extremely good results are obtained in clean lng.
• EXAMPLE V 500 g. of the composition prepared according to Example II are introduced into a dry-cleaning apparatus containing 400 l. of trichloroethylene. Subsequently 25 kg. of woolen mens wear are introduced into the apparatus. Very good results are obtained in cleaning, even with a very low filter pressure.
• EXAMPLE VI 25 kg. of raincoats to be cleaned are introduced into a dry-cleaning apparatus containing 400 l. of perchloroethylene. Subsequently 1500 g. of the composition prepared according to Example III are added. The cleaned raincoats are extremely fresh and clean. In this case again, the filter pressure remains very low.
