Four percent ass on (owf) of a finish is required on a fabric having a weight of 0.60 kg/m. Consider the wet picks up as 80%, speed of the fabric as 90 m/min and density of liquor as 1.2 g/ml.
Question 55 (Textile Engineering & Fibre Science)
Finish consumed in kg/min is
| (A) | 2.16 |
| (B) | 2.70 |
| (C) | 5.00 |
| (D) | 5.40 |
[Show Answer]
Given in the question-
Add-on %=4 %
fabric weight=0.60 kg/m
Wet pick-up%=80%
Speed of the fabric=90 m/min
Density of liquors=1.2 g/ml
Concentration % of the finish required in the bath=?
Firstly we have to calculate-
Fabric weight=0.60 kg/m x 90 m/min
Fabric weight=54 kg/min
Weight of finish=fabric weight x add-on
Weight of finish=54 x 4%
Weight of finish=54 x 4/100
Weight of finish=216/100
Weight of finish=2.16 kg/min
or
Finish consumed in kg/min=2.16 (Ans)
