NOVEL BLEACHES FOR LOW TEMPERATURE WASHING

The strategy of sustainable development in washing of textiles imposes many criteria: application of effective and biodegradable detergents, reduction of energy consumption, and elimination of harmful components and minimal load of waste water. Well-chosen high effective detergent ingredients with high efficient components applied in low temperature (LT) would be able to maintain quality and hygiene level. The primary role is of bleach active agents in washing are discoloration of coloured stains that can not be effectively removed by other detergent ingredients (surfactants, builders). Bleach is not associated only with favourable washing performance but also with drawbacks such as degradation of textiles to be washed in frequent cycles. The selection and evaluation of a bleach to be applied would be estimated according following criteria: efficiency, hygiene and gradual control release. The research deals with stain removal of detergents with peroxy bleaches, peracetic acid (PAA) and phthalimidoperhexanoic acid (PAP), applicable for low temperature processing.
