Fibre Chemistry Aims and scope

Conclusions

The presence of two forms of moisture in polyacrylonitrile fibre has been shown by thermogravimetric analysis: free water and capillary water.

Values for the heat of desorption of the free and capillary moisture have been determined: these are, respectively, 2.48 and 5.59 MJ/kg of evaporated moisture, respectively.
