Moisture in Textiles
01 April 1937
STUDY of the electrical properties of textiles and their dependence on atmospheric conditions and naturally-occurring impurities in the material has resulted in important economies and improvements in the use of textile insulation in the telephone industry. Recently, calculations have been made as to the moisture content and swelling of cotton at various equilibrium conditions, based on assumptions, first as to the structure of the cotton hair,* then as to the * In keeping with recognized terminology, the individual cotton fiber is called a hair, suggestive of its morphological origin. 228 MOISTURE IN TEXTILES 229 location and distribution of the internal surface upon which moisture might condense, and finally as to the manner in which moisture may be held upon this internal surface. From this rather specific picture of the cotton hair structure it has been possible to calculate moisture contents and swelling properties Fig. 1--Moisture sorption and electrical properties of raw cotton.
