Abstract
Results obtained by the thermogrammetric analysis of filaments are reported in this paper.
Cotton filaments which had been kept in the atmosphere of R.H. 100% for about one day showed remarkable hydroextracting as the temperature of the capsule of thermobalance rose.
It was found that cotton samples which had been left in the perfect dry atmosphere still had some residual moisture.
Polyester filaments which had been kept in the dry atmosphere showed increase in their weight by temperature rise, instead of decrease. When they had been kept in the atmosphere of R. H. 100% they decreased the weight by heating of the capsule because hydroextracting was induced.
The cotton and polyester filaments which had been cut with a sharp knife about 1mm long were also analyzed by thermogrammeter.
These short filaments showed some decrease in the absorption power compared with the long ones.
