Fig 4.9:- Effect <strong>of</strong> <strong>co</strong>ncentration <strong>of</strong> PU on Add on % <strong>of</strong> fabric.<br />
From Table 4.9 and Figure 4.9 indicate that as the <strong>co</strong>ncentration <strong>of</strong> polyurethane increases<br />
from 10 g/l to 90 g/l, the values <strong>of</strong> Add on increases from1.13 to 9.38. This is may be due to<br />
the increase in the <strong><strong>co</strong>ating</strong> layer on the fabric surface.<br />
