  1. 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
