“…The commonly used methods for the dewaxing of cotton for analytical or research purposes utilize periods of extraction varying from 4 hours [1,2,4] to two successive periods of 24 hours each [27] and use a great variety of solvents, techniques, and temperatures which are frequently inadequately specified. Benzene [13,22], chloroform [6,12], carbon tetrachloride [20], ethyl alcohol [9], isopropyl alcohol [17], alcohol-benzene mixture [15], trichloroethylene [10], and ether and other solvents [5] have been used or recommended for extraction of the cotton wax.…”

“…The amount of wax present influences the classer's estimate of fibers [1] ] and has been said [29] to be the chief cause of discolorations of bleached fabrics during storage. Hess has been credited with the statement [30] that we cannot understand the chemistry of cellulose itself without a knowledge of the materials that accompany it.…”

Solvent extractions of many samples of cotton showed that the usual methods of wax extraction are not always adequate for general use, particularly on cottons whose extractable matter has been changed by manufacturing operations such as the addition of spinning oil or warp size, or the removal of part of the wax by bleaching processes. The usual simple extractions may be satisfactory for routiue work on raw or processed cottons if the solvent is selected according to the type of cotton and to the purpose of the extraction. If, however, an accurate estimation of amount of wax is needed, a more inclusive method is desirable. The alcoholchloroform extraction procedure developed by Conrad is shown to be such a method. Several of the various other methods of extraction discussed are more suitable for dewaxing cotton for special uses than for analysis for wax content.
