2. Feasibility of low salt dyeing
The Sumifix HF series, which produces high color yield with little inorganic salt, reduces the costs of dyes and auxiliaries.

The advantage of low-salt dyeing
Reduction of Glauber's salt concentration by 10g/L
Liquor ratio 1:10, ¥500 reduction in the cost of Glauber's salt
Liquor ratio 1:20, ¥1,000 reduction in the cost of Glauber's salt
(Glauber's salt ¥50/kg, substrate 100kg)
Comparison on costs of dyes and Glauber's salt: Brown (Yellow-Red-Blue)
Cost of dyes and Glauber's salt (yen/100kg of substrate)
Dye: market price, Glauber's salt: ¥50/kg, liquor ratio 1:20 |
Comparison on costs of dyes and Glauber's salt: Brown (Yellow-Red-Navy)
Cost of dyes and Glauber's salt (¥/100kg of substrate)
Dye: market price, Glauber's salt: ¥50/kg, liquor ratio 1:20 |
