Viscose fabrics is to be resin finished with DMDHEU by pad-dry-cure method. Assume that
Mass of fabric per unit area : 200 g/m2
Width of fabric : 100 cm
Speed of the machine : 50 m/min
Concentration of pad liquor : 100 g/l
Wet pick up : 100%
Specific gravity of padding liquor : 1.0
Molecular weight of anhydroglucose unit : 162
Question 55 (Textile Engineering & Fibre Science)
Assuming that the reaction takes place in amorphous region only and that the fabric Crystallinity is 33%, the number of cross links formed per anhydroglucose unit after curing would be approximately
| (A) | 0.07 |
| (B) | 0.14 |
| (C) | 0.28 |
| (D) | 0.35 |
