Humidity table mounted on a wooden board made by Baird & Tatlock, London, Ltd. Properties of cotton yarn such as count, yardage, strength and elongation of cotton yarn are directly influenced by the amount of moisture present. Therefore it was necessary that standard conditions of humidity and temperature were adopted and recognised in the testing of yarns and fabrics. This humidity table was likely located next to a moisture gauge or hygrometer. By using the humidity table and hygrometer, testers could ensure atmospheric conditions were constant and did not affect test results.
