Definitions

  • the present invention relates to compositions and methods to allow wet-cleaning, including oil stain removal, and subsequently drying in a tumbler dryer, of sensitive garments and other fabrics made of water-sensitive protein fibers such as wool, cashmere or silk without any dimensional changes, surface damages and dye or color loss.
  • These compositions and methods can be applied in a professional or household cleaning process.
  • Sensitive garments and other fabrics may be cleaned and dried in a variety of manners using professional wet or dry cleaning processes or modem household laundry equipment. Sensitive items including garments and fabrics made of hair, silk, rayon, animal hair, animal skin and mixed spun materials, have a tendency to shrink when they are washed in water. In order to avoid shrinkage caused by washing in water, many of these sensitive garments and fabrics are conventionally dry cleaned.
  • Dry cleaning has been used to describe processes for cleaning textiles using non-aqueous solvents. Dry cleaning is an old art first discovered in the mid-19 th century when potential to use petroleum-based solvents to remove grease, wax and oil-based stains from textiles was discovered. Solvent cleaning was first recorded in the United Kingdom in the 1860s with gasoline and kerosene as first solvents used.
  • Chlorinated solvents were introduced after World War I; since the mid-1930s the most commonly used solvent has been tetrachloroethylene, also called perchloroethylene which has the advantage of being stable, non flammable, and having better cleaning capabilities than aqueous solvents for removal of oil-based stains. Since that time most fabrics having a tendency to shrink by contact of water, or which are judged to be too valuable or delicate to be subjected to aqueous laundering processes, are dry cleaned.
  • perchloroethylene While perchloroethylene is superior to the non-aqueous solvents that it replaced, it has several disadvantages. Particularly, perchloroethylene has been identified as a hazardous air and ground water pollutant (listed as such under the Clean Air Act by the U.S. Environmental Protection Agency and declared as a toxic chemical by California in 1991); it has been also long associated with nervous-system, severe skin irritation, liver and kidney disorders amongst industrial workers and listed as probable carcinogen by the International Agency for Research on Cancer (IARC) in 1995.
  • IARC International Agency for Research on Cancer
  • glycol ethers have been recommended for use in dry cleaning, more particularly propylene glycol tert-butyl ether (PTB), propylene glycol n-butyl ether (PNB), dipropylene glycol tert-butyl ether (DPTB) and dipropylene glycol n-butyl ether (DPNB) ( US 5,888,250 ; US 6,156,074 ; US 6,273,919 and US 6,350,287 from Rynex Holdings Ltd.).
  • PTB propylene glycol tert-butyl ether
  • DPTB dipropylene glycol tert-butyl ether
  • DPNB dipropylene glycol n-butyl ether
  • Solvent-based dry cleaning processes present several limits and/or disadvantages compared to wet cleaning :
  • solvent-based dry cleaning processes are quite effective for removing oily soils and stains, they are not optimal for removing particulates such as clay soils or the water-soluble stains such as the sugars, commonly found in many fruit drinks and carbonated beverages; it may also require special treatment conditions to remove proteinaceous stains.
  • dry cleaning equipments are substantially more capital intensive compared to wet cleaning equipments. It also compares unfavourably as to the operating costs, and specifically with regard to solvent sludge and filter removal requirement, higher repair and maintenance costs due to higher technical complexity and higher consumption of energy and water.
  • Wet cleaning is a non-toxic, environmentally safe alternative to dry cleaning, utilizing computer-controlled washing machines, biodegradable soaps and conditioners, and various types of pressing equipment that may be specialized for many different fabric and fiber types.
  • Modem wet-cleaning technology was developed by Miele in early 1990s and involves the use of water as solvent instead of organic solvents. Water usage as a solvent offers several advantages:
  • the wet cleaning process in a professional wet cleaning operation is similar to washing garments in a modem household washing machine, albeit in a controlled environment regarding to speed, temperature and water volumes.
  • Professional wet cleaning operations require specially designed equipment such as wet cleaning machines and dryers.
  • wet cleaning process require moderately more sorting prior to cleaning because of more delicate cleaning and also moderately more finishing time.
  • GB1515792 discloses a wool washing composition, which produces less shrinkage, and comprises a surfactant and a blend comprising at least one alkali metal pyrophosphate, at least one alkali metal tripolyphosphate, and at least one partial ester of orthophosphoric, pyrophosphoric or tripolyphosphoric acid.
  • US 5,634,947 discloses a wet cleaning system that uses a solvent of propylene glycol monomethyl ether containing 4% to 50% by volume of water.
  • WO 98/56975 teaches a shrinkage prevention agent that contains at least one organic acid, with terpene and phenol of plant origin as its effective components.
  • organic acids acetic acid is listed with cyclotene, 2-cyclopentenone, para-cresol, meta-cresol, orthocresol, furfural alcohol and guaiacol, in addition to other components in trace amounts.
  • the anti-shrinkage agent is used as 0.01-0.05 parts by volume per 100 parts of regular water.
  • wet cleaners typically either add cationic surfactants (softeners) during the last rinse of the washing cycle, thereby coating the garments against sticking, or put the dry garments into the garments dryer to soften them mechanically.
  • US 4,213,867 discloses a fabric rinse conditioning composition comprising water, isopropanol, a phosphate ester and a quaternary ammonium compound.
  • WO98/41602 discloses a fabric laundry treatment composition, which is added during the rinse step, comprising: a) a fluorocarbon polymer or a fluorocarbon copolymer or mixtures thereof; b) a deposition aid comprising a cationic softening compound or a polymeric delivery aid or mixtures thereof.
  • CA 2,531,234 addresses the question of laundering processes of sensitive garments in a conventional home washing machine.
  • the use of aqueous laundering process in a conventional washing machine is considerably more convenient and inexpensive than virtually any other laundering method, but can produce inacceptable results when applied to a broad range of delicate or dry-clean only garments.
  • the system in CA 2,531,234 uses a flexible polymer wrap container to avoid abrasion and stress that severely damage the garments.
  • the object of the present invention is to propose methods and associated compositions for wet cleaning and drying of all-types of delicate garments allowing efficient stain removal, including oil stains removal, on sensitive garments generally unsuitable for water washing, without incurring dimensional changes, shrinkage, surface damages, dye or color loss.
