  • Patent number: 6743761
    Abstract: A one step method for the treatment of a non-finished textile component is provided. The method comprises the combination of a bleaching and de-sizing treatment steps into a single step and comprises treating a non-finished textile component in an aqueous treatment solution of a hydrophobic bleaching system and a de-sizing system. Preferred hydrophobic bleaching systems are combinations of hydrogen peroxide and a hydrophobic bleach activator or a 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 allows significant savings in both energy and time due to the elimination of multiple washing and/or drying stages and lower bleaching temperatures.

  • Patent number: 6740126
    Abstract: A method for the application of durable press to textiles via the pre-treatment bleaching of a non-finished textile component followed by the application of a durable press finish is provided. The method comprises the steps of treating a non-finished textile component in an aqueous bleaching solution of hydrogen peroxide and a hydrophobic activator or hydrophobic peracid for a time sufficient to bleach the textile component followed by application of the durable press finish preferably via immersion in an aqueous solution of formaldehyde, a cross lining catalyst and a silicone elastomer forming material or a solution of alkylene urea and a crosslinking catalyst. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method allows significant savings in both energy and time due to the lower bleaching temperatures possible via the present method as opposed to conventional peroxide processing.

  • Publication number: 20030166495
    Abstract: Wash added fabric care compositions including a dispersible polyolefin wax. More particularly the present invention relates to detergent compositions including dispersible polyolefin wax. The polyolefin wax may be at least partially modified to contain various functional groups such as carboxyl, alklamide, sulfonic acid or amide groups. The polyolefin wax may be introduced in the form of a suspension, dispersion, or emulsion. A method for applying these compositions during the wash cycle of a laundry process is also included.

  • Patent number: 6569209
    Abstract: A method for the treatment of a non-finished textile component in a cold batch process 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 followed by a treatment time of from about 1 hour to about 15 hours at a temperature of 35° C. or less. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method provides acceptable whiteness and superior fiber protection and fabric strength benefits in significantly reduced treatment times versus conventional.
