The Sumifix HF series, hardly influenced by alterations in dyeing conditions, is excellent in color reproduction.

Sumifix HF series

Hardly influenced by changes in dyeing conditions (temperature, inorganic salt/alkali concentration, liquor ratio, pH and time) Superior reproducibility of results between laboratory tests and practical dyeing, and between batches Easy color matching, color reproduction with high accuracy in practical dyeing, significant reduction in shading and re-dyeing, and considerable improvement in productivity

Conventional high-temperature type reactive dyes

Easily influenced by changes in dyeing condition (temperature, inorganic salt/alkali concentration, liquor ratio, pH and time) Inferior reproducibility of results between laboratory tests and practical dyeing, and between batches Slow color matching, low reproducibility in practical dyeing, frequent shading and re-dyeing, and low productivity

Sumifix HF dyes are excellent in color reproduction, being hardly influenced by changes in dyeing temperature, salt concentration, liquor ratio or pH.
