High-fixation type reactive dyes Sumifix HF series |
Sumitomo Chemical/Sumika Chemtex has been intensifying worldwide promotion of the Sumifix HF series, the much-awaited, high-temperature/high-fixation type reactive dyes, now extended to a 7-item line-up.
The HF series is expected to produce considerable effects in deep dyeing, with the most remarkable feature being the high fixation rate (over 80%). A uniform development of dye exhaustion curves in
combination dyeing is another characteristic. It has seven special qualities; 1) high dyeability, 2) feasibility of low salt dyeing, 3) shorter dyeing time, 4) excellent reproducibility, 5) suitability
for mixed dyeing 6) excellent wash-off property and 7) good fastness levels.
Sumitomo stresses the point that Sumifix HF is highly effective for the dyeing of mixed fiber, particularly that with spandex. |
Advantages expected in deep dyeing
Sumitomo Chemical/Sumika Chemtex have extended the Sumifix HF series to the 7-item line-up, Yellow 3R, Scarlet 2G, Red G, Red 2B, Blue 2R, Blue BG and Navy 2G.
According to numerous data on the effects provided by Sumitomo Chemical/Sumika Chemtex, the seven items in the Sumifix series can take full advantage of being of a high-temperature type through considerable
reduction of salt required in dyeing.
Benefits are expected especially in deep-dyeing, because of its high cost.
Sumitomo Chemical/Sumika Chemtex place emphasis on the considerable advantage of Sumifix HF dyes in the dyeing of mixed fiber, giving various data on their dyeability and economical efficiency.
