Viscose fabric 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
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
