Dyeing properties of dobby suede

The dyeing property of sea-island dobby suede fabrics was investigated in respect of dyeing temperature,dyeing time,the building-up of dye and color fastness and the optimal dyeing process was determined as follows: dyeing started from 40-(50 ℃),then raised the temperature slowly to(90 ℃),kept this temperature for(20 min),and raised the temperature slowly 110-(120 ℃),kept the temperature for(50 min;) Finally,the dyed fabrics were subjected to reductive cleaning.And the appropriate conditions of reductive cleaning were present: sodium carbonate(2 g/L),cleanser(2 g/L) at(80 ℃) for(20 min.)
