New Eco-Friendly Method of Cellulosic Product Bleaching with Simultaneous Disinfection
Journal Title: Fibres and Textiles in Eastern Europe - Year 2015, Vol 23, Issue 3
Abstract
In this article, a bleaching method with simultaneous disinfection using hydrogen peroxide in the gas phase (Vaporised Hydrogen Peroxide - VHP) is presented as an innovative, environmentally friendly, low-temperature method without wastewater generation. After the process, the cellulose products are characterised by acceptable whiteness and microbiological purity. The method presented is an eco-friendly alternative for the conventional water- and energy intensive bleaching process with reference to products made of cellulosic fibres to be applied in special applications: medical (gauze, cotton wool, bandages) and hygienic (e.g. face masks used in the prophylaxis of bacterial and/or viral infections). After tests of the sensitising effect on animals, the bleached materials were considered safe for potential users.
