Preliminary Studies of Non-Aqueous Volatiles in Lint Cotton Moisture Tests by Thermal Methods

A comprehensive review of the standard test methods for moisture in lint cotton in 11 countries revealed that almost all methods utilize the oven-drying technique [1]. The pri-mary areas reviewed over the period 1930 to 2007 included all three classes of standard test methods – voluntary, national and international – and the known sources of error in the procedures. As a final note this review also focused on emerging trends and current issues related to the standard test methods by oven drying. The usual practice in the standard oven drying proce-dure is to dry the specimen in an oven at about 105–110°C at standard textile testing conditions (70°F and 65 % rela-tive humidity). The raising of the temperature of the air in the oven lowers its relative humidity, since the saturation humidity increases greatly [2].1 However, the relativ
