Definitions

  • This invention relates to fabric cleaning compositions, more particularly to dry compositions useful for cleaning carpets, curtains and similar furnishing fabrics.
  • carpets and other furnishing fabrics have, for many years, been subjected to cleaning using various wet systems involving shampooing, steam-cleaning and straightforward washing where the fabric can be conveniently treated by such methods.
  • a particular problem arises from wet methods in the time taken for the carpet to dry prior to being available for its normal use as a floor covering.
  • the pile of a carpet can be flattened by people walking on it, or placing furniture on it when it is wet.
  • surfactant or soap used in the wet cleaning methods are removed, there is a tendency for the fabric to pick up soil at an enhanced rate.
  • United States Patent Specification No. 3 630 919 discloses a dry cleaning composition containing a minor amount of a colloidal silica having a particle size in the range 0.01 to 20 ⁇ m, a major amount of finely divided carrier having a bulk density in the range 6 to 22 Ibs.fft3 (96 to 352 kg/m 3 ) and water.
  • Suitable carrier materials disclosed include various diatomaceous earths, sawdust, talc, cork, corn cob, Fuller's earth and the like.
  • United States Patent Specification No 4035 148 discloses a further surfactant-free composition consisting essentially of a water-soluble phosphate and a water- insoluble alumina having a particle size less than 3 pm. This composition is said to impart a soil repellent finish to carpets and the like.
  • the preferred particle size for the alumina is from 0.005 to 0.1 pm.
  • British Patent Specification No 2037311 discloses a pulverulent, non-toxic cleaning agent comprising 70 to 30 parts by weight of the solvent mixture consisting of water and certain organic solvents, and a pulverulent carrier of which the particle size is between about 5 and 1000 pm consisting of starch, flour or woody material.
  • terpenic hydrocarbons which are liquid at 20°C and have a boiling point under atmospheric pressure between 150 and 250°C
  • aliphatic hydrocarbons which are liquid at 20°C and have boiling points under atmospheric pressure of between 90 and 300°C
  • oxygenated solvents selected from mono- and di-alkyl ethers of ethylene glycol and acetates of ethylene glycol mono-alkyl ethers.
  • the present invention provides a fabric cleaning composition
  • a fabric cleaning composition comprising a carrier material and as cleaning liquid at least 5% by weight of the composition of diethylene glycol dimethyl ether.
  • Diethylene glycol dimethyl ether is also known as diglyme.
  • the liquid component in the fabric cleaning composition may also comprise water up to 94% by weight of liquid and, optionally, a small quantity of a surfactant may be included.
  • a surfactant is in the range 1 to 5% by weight of the total composition.
  • Compositions containing a surfactant which produces a dry residue which can be readily removed are preferred.
  • the carrier materia! may be selected from a wide range of solid materials including solids such as sodium sulphate, calcite and many other cheap carrier materials.
  • the carrier material is a porous material able to absorb a significant amount of the preferred solvent and to reabsorb the liquid component from the fabric.
  • a preferred carrier material is a silica comprising at least 5% by weight of the composition of the preferred solvent.
  • the silica is a silica hydrogel.
  • Suitable silica hydrogels for use in the compositions provided by this invention can be obtained from Joseph Crosfield & Sons Limited, Warrington, England, and are usually sold in a form containing about 68% by weight water.
  • Another preferred carrier material is a particulate porous polymeric material.
  • Suitable polymeric materials are disclosed in, for example, British Patent Specification No 1 411 230 and No 1 576 228 and in European Patent Applications Nos 006 138 and 0 105 634.
  • carrier materials include cellulosic compositions and urea/formaldehyde resin powders such as those disclosed in British Patent Specification No 2 112013 and Japanese Patent Specification 1981-12242.
  • Certain of the inorganic carriers are usefully be used in combination with the more expensive inorganic or polymeric carriers or as extenders in more complex mixtures.
  • additives may be incorporated into the fabric cleaning compositions provided by this invention such as perfumes, antistats, bacteriostats, fillers such as inorganic salts and softening agents including various cationic surfactants.
  • Tests have now been developed in an attempt to quantify the effectiveness of the cleaning compositions provided by the present invention in comparison with known cleaning techniques and compositions.
  • First of all artificial soil has been developed which comprises vacuum cleaner dust, triolein and carbon black in the ratio 65:25:10 by weight. This is applied to a carpet sample as a spray using, as avolatile solvent, isopropanol (IPA). After drying the carpet is treated with a vacuum cleaner to remove loose dust.
  • IPA isopropanol
  • IPA isopropanol
  • IPA isopropanol
  • a textile abrasion tester has been adapted to brush the carpet's surface in a reproducible and predetermined pattern under various weights of brushing pressure. The cleaning effect has been measured using the Hunter colour co-ordinates L,a,b. The results are quoted as a percentage of the total colour regain (TCR): where the subscripts refer to the samples being unsoiled (u), soiled (s) or cleaned (c).
  • a mixture (A) was prepared of the solvents:
  • compositions comprising silica hydrogel (1), Na2S0410H20 and diglyme and similar mixtures in which the silica hydrogel was replaced by Accurel PA@ resin powder.
  • the results are set out in Table VI.
  • the mixtures are expressed as % by weight of the composition and as before were applied at 40 g/m 2 .
  • a preferred form of the invention comprises a composition in which the carrier is a particulate porous polymeric material and the cleaning liquid comprises at least 7.5% by weight of the composition with diethylene glycol dimethyl ether.
  • a further preferred form of the invention comprises a composition in which the carrier material comprises a porous silica and the cleaning liquid comprises at least 15% by weight of the composition of diethylene glycol dimethyl ether.
