Lusynton® SE - Prismadye

November 2009 Page 4 of 10 Lusynton ® SEBASF Soft Bleach process- This enables pretreatment to be shortened by omitting alkaline boiloff;- A greater amount of peroxide can be applied to obtain a full whitewithout hypochlorite;- Processors who have already shortened the pretreatment processcan expect:- a higher degree of whiteness and;- a better DP value for less peroxide.A particular advantage in the case of starch-sized fabric is the fact thatLusynton ® SE can be combined with enzymatic desizing.Effect of Lusynton ® SE on absorbency:
