PERISTAL BLI ECO System Protects the Environment and Your Health
The PERISTAL BLI ECO system offers an environmentally friendly alternative to oxidative spray bleaching of indigo-dyed denim jeans with potassium permanganate (PP, KMnO4) or chlorine bleach. PERISTAL BLI 85 N ECO and PERISTAL BLI 15 ECO are a two-component bleaching system, which consists of perfectly matched oxidizing agents. The products are sprayed on the areas to be bleached, then the garments are dried in a tumble dryer or oven for 15 to 20 minutes at minimum 80 °C, followed by a washing step. Due to the strongly oxidative effect of the bleaching agents the indigo is chemically destroyed on the treated areas. During the final wash process the decomposition products of the PERISTAL BLI ECO bleaching system are washed out as non-poisonous, inorganic salts.
An Eco-friendly Substitute for KMnO4 and NaClO
In the bleaching process the indigo dyestuff is locally destroyed with a potassium permanganate solution (KMnO4) or chlorine bleaching lye (sodium hypochlorite, NaClO). The products of the oxidative decomposition are water-soluble and are removed from the textile fabric in a following washing step. For the sake of the environment, chlorine as well as manganese, a heavy metal, should be avoided. For this reason we developed the PERISTAL BLI ECO system, an eco-friendly alternative. Thus, we can avoid the use of polluting potassium permanganate in the denim production process.
Conform to ZDHC and bluesign®
The PERISTAL BLI ECO indigo bleaching system is an environmentally friendly, physiologically harmless and secure alternative to processes which use chlorine or potassium permanganate. Still they are highly reactive oxidizing agents. The essential industrial safety measures for protecting your employees should be strictly followed. The aerosols, which are formed during the spray application, must not be inhaled. For this reason, it is important that the workers wear appropriate safety equipment, such as respiratory protection, safety goggles, gloves, hoods and protective clothing, and that waste spray mists are optimally sucked off.
