Test Method for Evaluating Adsorptive Fabrics

Source

Albany International Research Co. has developed a test apparatus and method for evaluating the protection afforded by various textile materials against low levels of toxic vapors. The test apparatus consists of a flow system that provides a constant challenge gas flow rate and concentration to be passed through the test specimen and a detection system that continuously monitors the concentration of the toxic component in the effluent gas stream. In the present apparatus, carbon tetrachloride is used as the challenge material at a concentration of 5.0 × 10-6 g/cm3. The traces of effluent concentration versus time obtained from the tests can be used to quantify total sorption capacity and sorption rate for the sample fabrics. Reproducibility studies have yielded coefficients of variation of 3.4% for total capacity and 5.5% for the sorption rate constant determined by this test method.
