Definitions

  • the invention relates to a method for applying chemical compounds to laundry articles using water ice as carrier.
  • dryer sheets which are impregnated with conditioning agents and allowed to tumble with the clothes in a dryer.
  • fragrance is imparted to the clothes that come into contact with these dryer sheets.
  • the dryer sheets are typically made of a spongy material and the conditioning agents are chosen such that they melt or flow at conventional dryer operating temperatures.
  • these dryer sheets suffer from several drawbacks. Because the conditioning agents are applied through contact between articles of laundry and the sheets, application can be splotchy and uneven. In addition, in order to assure that all articles of laundry come into contact with the sheet, it is necessary for the dryer sheets to be put in the laundry early on in the drying cycle.
  • any fragrances in the conditioning compositions are likely to volatilize during prolonged exposure to the heat of the drying cycle, leaving little residual fragrance on the textile surface at the end of the drying process.
  • This problem occurs specifically in industrial dryers, such as those used by the hotel industry, which operate at much higher temperatures than do conventional household dryers. In fact, many industrial dryers work at temperatures hot enough to melt dryer sheets.
  • the conditioning agents that can be used with dryer sheets are limited because they must be selected from compounds that melt or flow in a fairly specific temperature range. The compositions that meet these criteria are not optimally suited for use as softeners and conditioners.
  • liquid or solid conditioners are housed in porous containers which are either allowed to tumble freely with the laundry in a dryer or which are attached to the drum of the dryer such that they spin with the laundry. These liquid or solid conditioners are then dispensed through the porous walls of the container during the drying process. As with dryer sheets, these porous containers apply conditioning agents by making direct contact with articles of laundry, which requires prolonged exposure to the laundry during the drying cycle and which may lead to an uneven application of the conditioning agents.
  • a fabric softener or conditioner is held in a container within a dryer and hot air is circulated over the container such that the fabric softener or conditioner vaporizes and is carried by the air stream over the laundry. This requires that the softener or conditioner be present during the hottest part of the drying cycle, resulting in the volatilization and loss of volatile fragrant components within the conditioning compositions.
  • the object of the present invention was to provide a new method for applying chemical compounds to laundry articles.
  • the present invention provides a method for applying at least one chemical compound to laundry articles, comprising the step of contacting ice comprising said chemical compound with said laundry articles.
  • the application of at least one chemical compound to laundry articles step is carried out during a wet treatment of said laundry articles comprising the steps of washing, rinsing and drainage
  • said method is carried out in a chamber containing said laundry articles.
  • the ice comprising said chemical compound is added to the laundry articles in form of blocks, pellets, cubes, sticks or snow in any geometrical shape.
  • water starts to freeze from the outside or surface to the inside of the respective water volume.
  • said chemical compound is released by the melting of said ice. Due to said melting of said ice said chemical compound comes into contact with the laundry articles. In the method according to the present invention said chemical compound comes into contact with the laundry articles due to said melting of said ice. As the ice comprising said chemical compound returns to the liquid phase it leaves an effective concentration of the chemical compound which becomes absorbed by the laundry articles. Therefore, the chemical compound when the ice is melting is thereby dispensed or deposited on and taken up or absorbed by the laundry articles.
  • the laundry articles are transported through said chamber (e.g. a steam tunnel or a chamber of an ironer) or are agitated (e.g. in a drier) when said chemical compound is released by the melting of the ice.
  • said chamber e.g. a steam tunnel or a chamber of an ironer

  • An example of a drum within a chamber is a drier drum of a drier for drying laundry articles.

The ice melted and the chemical compound was thereby dispensed on and taken up or absorbed by the laundry articles in the drier, while the water content resulting from the molten ice subsequently evaporated.
  • Uptake or absorption of the chemical compound by the laundry article was checked by comparing untreated laundry articles with treated laundry articles.
  • Laundry articles treated with ice comprising a fragrance were subjected to a smell test by a panel of individuals who confirmed that the treated laundry articles did comprise the fragrance while no smell of fragrance was detected in respect to the untreated laundry articles. As test the triangle test was used which was described above.
