    Patent number: 6830591
    Abstract: A method for the treatment of a non-finished textile component is provided. The method comprises the steps of treating a non-finished textile component in an aqueous bleaching solution of hydrogen and a hydrophobic bleach activator or hydrophobic peracid. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method provides superior fiber protection and fabric strength benefits versus conventional processing as well as significant savings in both energy and time due to the lower bleaching temperatures.

  • Autonomous cleaning composition and method
    Publication number: 20040162227
    Abstract: A solid cleaning composition and method of manufacture are disclosed, which provide a long-term, solid cartridge made of cleaning agents and a solubility limiting agent for controlling an equilibrium concentration of the composition in a solvent, such as water. In use, the cleaning agents are dissolved only to a predetermined concentration needed for a single dose of a cleaning appliance, such as a clothes washing machine. The solid cleaning composition may be cyclically exposed to water. Controlled dissolution of the cleaning composition releases a desired quantity of cleaning agents in each cleaning cycle. The use of potassium silicate as a solubility controlling compound permits manufacture of the cleaning composition at ambient temperatures and pressures. The cleaning composition may be molded or cast into a desirable shape for controlling surface area.
