A method has been developed for the rapid analysis of water adsorbed on cotton or modified cottons. The sample is extracted with anhydrous acetone and the solution is chromatographed on a Porapak T column. Quantitation is based on an internal methanol standard. Formaldehyde, which can also be extracted in acetone, can be measured. An ap plication of the method to the analysis of some flame-retardant fabrics is also described.
