OXIDISED STRACH
INTRODUCTIONOxidized Starch is modified starch used an additive for coating & surface sizing by Textile Manufactures
DESCRIPTIONOxidized starch has a carboxyl group attached to it, which gives the desired characteristics for Textile applications; oxidized starch has increased water holding and water absorbing qualities. Which decrease the tendency of penetration or migration in a pigment coating formula.Oxidised starch has improved whiteness and it cooks to thin paste, which is relatively clear at elevated temperature. Oxidized Starch gels show considerably less set back and is less cloudy and more fluid than unmodified parent starch .Moreover being anionic Oxidized starch strong absorbers cationic dyes.
- Improved printability and pigment coating.
- Improved brightness and smoothness.
- Improved surface strength and provide holdout of printing inks

APPLICATION:-
PAPER INDUSTRIES:-
It is used as a wet end additive for surface treatment of the paper & board. It is filler retention as provide strength properties to sheets. In the convention system it can be added as a paste of solution at the beater end in a continuous system just before the refiners.
PACKAGING:-
Oxidized starch is available in 25-50 Kgs. Plastics lined HDPE.Woven bags.
