US Patent No: 5234465

Pad-dyeing of cellulose fibers with sulfur black dyes: mixture of dithionite and glucose reducing sugar as reducing agent in aqueous alkaline dye bath

---

Abstract

---

Cellulose fibers are dyed ecologically soundly with sulfur black dyes by the pad-dyeing process by avoiding sulfides as reducing agent by replacing them by a dithionite-based mixture with at least one reducing sugar. A high color yield, a deep black shade and good reproducibility are ensured. The preferred reducing sugar is glucose.
