Concentrated product, prevents cross-staining of dyes
Esto-PVP is a concentrated product to avoid cross-staining of dyes in washing-off of dyed and printed substrates. Esto-PVP can be used in batch as well as in continuous operation. During washing-off, Esto-PVP forms weak complex with anionic dyes which is kept in dispersion throughout washing process and prevents re-deposition thereby cross-staining is avoided. Due to its good rinse ability, Esto-PVP is easily washed-off and does not interfere in subsequent dye fixing or softening. Esto-PVP can be used against conventional washing off agents. Esto-PVP is very good levelling agent for vat dyeing
