Abstract
|
|
|
|
The sappan wood dyeing conditions and mordanting methods suitable for ramie as well as silk were investigated. The HVC values of dyed silk and ramie fabrics were varied by the amount of sappan wood in the dyeing bath, while the optimum weight of sappan wood for the extraction of dye was around 15 g/l. The K/S value of dyed silk fabric showed no signincant difference in the pH range of 3.5 to 6.5. However, the K/S value of dyed ramie fabric was increased in proportion to the pH value of dye bath. The K/S values of both dyed silk and ramie fabrics were most increased at the highest dyeing temperature in the range of 30 to 90°C. By various mordantings, the HVC values of dyed silk and ramie fabrics were differentiated and it´s color fastness could be improved.
