3. 4 Moisture diffusivity through Nylon-6 material
Effective moisture diffusivity through the Nylon-6 material is calculated using equation 14. It is dependent
upon many factors which include concentration gradient for water vapour transport to the surface, shape of pellets,
temperature of drying air etc. Effective moisture diffusivity was calculated for all trials, and found out to be in the
range of 4 - 6.5 X 10-9cm2/sec. calculated value of effective moisture diffusivity is in good agreement with the value
reported in the literature which
