Question 52 (Textile Engineering & Fibre Science)
Scoured and bleached cotton fabric was dyed with reactive dye under the following conditions:
Temperature of dyeing : 40o
Shade : 3%
Fixation efficiency: 65%
In the rate of hydrolysis of dye is known to be 5% more for every 10o C rise in dyeing temperature, the amount of dye fixed on cotton (g of dye/kg of fibre), if dyed at 50o C, accurate to one decimal place, would be …………….
