Southern Regional Research Laboratory, New Orkans, Louisiana 70179, U. S. A. 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.
Key Words: Cotton modified cotton. THPOH-treated fabric. H2O CH2O CH3OH acetone Porapak T. GLC analysis. Flame retardancy.
