BLEACHING – PEROXIDE

AVCO-ACTIVANT LTB
ACTIVATOR FOR PEROXIDE BLEACHING

The effectiveness of hydrogen-peroxide in bleaching of cellulosic fibres is depended upon the reaction time, high temperature and alkaline pH. Use of elevated temperatures can lead to loss of peroxide due to thermal decomposition, also the fabric strength can be diminished due to the action of free radicals and high pH. High temperature and high pH are affecting also the fastness properties and shades of colours, when bleaching blends of raw cellulose with pre-dyed yarns. It may deteriorate also the physical properties and elasticity of blends of cellulose with sensitive fibres such as Lycra, Tencel, Polyacrylamide, Wool and Viscose.Use of Avco- ACTIVANT LTB in peroxide bleaching enables bleaching at lower temperatures and lower pH.

AVCO-ACTIVANT PBI
PEROXIDE BLEACHING INTENSIFIER

AVCO-ACTIVANT PBI is a special additive acting as a Post Bleaching Intensifier in peroxide bleaching processes.
In peroxide bleaching there is always a residue of 20-30% of the original amount of peroxide that is not decomposed, and remains in the bleaching liquor at the end of the bleaching cycle as waste. Normally this quantity is dropped out from the machine at the end of the bleaching process. AVCO-ACTIVANT PBI is using this leftover by activating the peroxide molecules for intensifying the whiteness results normally obtained in peroxide bleaching processes.
