A knitted fabric is to be dyed with a low substantive dye to 2% shade using exhaust method.

Question 82 (Textile Engineering & Fibre Science)

If the dye concentration is set 1 g/l, the material to liquor ratio, assuming 50% exhaustion at equilibrium, would be

[Show Answer]

Option A is correct.

Given in the question-

Dye %=2%

Dye concentration=1 g/l


The material to liquor ratio(M:L)=?

Assuming weight of fabric=100 kg

Dye=100 x 2%

Dye wt=2kg

Exhaust dye=2000 x 50/100

Exhaust dye=1000 gm

Exhaust dye=1 kg

By formula-

Concentration=Weight of dye/Volume of liquor
