Abstract
It was the purpose of this problem to determine (1) the effect of time and temperature of presoaking on the rate and degree of the partial acetylation of different varieties of cotton fibers with the time and temperature of the acetylation held constant and (2) to study the effect of the acetylation temperature under constant conditions of presoaking. The degradation of cotton fibers in the production of partially acetylated cotton is due primarily to the time and temperature used in the acetylation process. It is therefore of prime importance to determine some method of reducing the time and temperature of acetylation to a minimum and still obtain the desired acetyl content. The effect of the time and temperature of presoaking on the rate and degree of acetylation was thus determined in order to obtain the optimum conditions of presoaking. Six different varieties of cotton fibers representing a wide range of physical properties were selected for this study. The cottons selected were Memphis, Empire Bale 92, Bob Shaw, Stoneville 2B, Acala 1517 and Lockett 140.
