Title:
METHOD FOR THE USE OF HYDROPHOBIC BLEACHING SYSTEMS IN COLD BATCH TEXTILE PREPARATION
Document Type and Number:
WIPO Patent Application WO2002068750
Kind Code:
A8
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 DEG 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.
