Equilibrium Moisture Relations for Textile Fibers

It is the purpose of this paper to present data on equilibrium moisture based upon the published work of Wiegerink [4] statistically recalculated by the present au thors. The study was first undertaken in the belief that Wiegerink's data could be made more useful if his curves of equilibrium moisture versus relative humidity could be extended with respect to temperature and relative humidity ranges and if the experimental variations in the data could be accurately minimized. In the analysis it was found that characteristic results for fibers could be explained in terms of physical-chemical principles which were presented and discussed in the first paper of this series [3]. The second publication [1] presented the mathematical details of the statistical correlation method.
