Embodiment I

[0087] The method for cold-batch bleaching of woven fabrics according to the present invention can be operated in the following manner. The chemicals listed in Table I below were added to tap water to prepare a bleach bath. The order of addition is as follows: Water - Humectant - Detergent - Peracid Stabilizer / Peroxide Stabilizer - Activator (if present) - H 2 o 2 -NaOH. The fabric is undegummed plain plain fabric (400R). The original fabric whiteness is 18 on the CIE scale. The bleach bath is pumped into the filling tank and maintained at a constant near-full level throughout the filling process. The fabric is conveyed at a packing speed of 30 meters per minute at a temperature of about 24° C., rolled up on a bar and sealed with a plastic cover. The fabric was then spun on an A-frame for the specified reaction time at room temperature followed by a thorough rinse in a jet washer. The bleached fabrics were dried and conditioned at 70F and 65% relative humidity for wetnes...

Embodiment II

[0095] The process for thermal batch bleaching of woven fabrics according to the present invention can be operated in the following manner. The bleach solution is formed by preparing a peracid stabilizer premix by diluting the ingredients to about 25% active and adjusting the pH to 5 to 5.5 with caustic. After preparing the stabilizer premix, prepare the bleach precursor premix by mixing the components in the following order: activator (if present) - water - humectant - suds suppressor (if required) and stabilizer premix . The bleach solution is then prepared and added to the jet machine by adding the following ingredients to the jet machine in the order listed: Lubricant - Bleach Precursor Mixture - Fabric Carrier - Detergent (if present) - H 2 o 2 -NaOH. The liquid / fabric ratio in the machine was 10:1. The temperature of the solution was raised to 70°C at a rate of 3°C per minute. After reaching this temperature, the solution temperature was maintained for 40 minutes be...

Abstract

Stability enhanced hydrophobic bleaching systems for textile applications and methods for using are provided. The bleaching systems comprise a hydrophobic peracid and a peracid stabilizing system of a preferred ratio of peracid to stabilizer. Preferred stabilizers to be used in conjunction with the hydrophobic peracids include diphosponic, multiphosphonic and amino phosphonic acid derivatives.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Serial No. 60 / 302,510, filed June 29, 2001 (Attorney Docket No. 8616P). technical field [0003] The present invention relates to enhanced stability hydrophobic peracid bleaching systems for textile applications and in particular to the use of specialized stabilizer systems for stabilizing peracids in bleaching solutions. Background of the invention [0004] In the industrial textile processing of natural fibres, yarns and fabrics, pretreatment or preparation steps are typically required in order to properly prepare the natural raw material for further use, especially for the dyeing and / or textile finishing stages typically required by commercial goods. These textile treatment steps remove impurities and color bodies that are either naturally present or incorporated into the fibers and / or fabrics through the spinning and weaving st...
