Preparation of Soluble Yarns by the Carboxymethylation of CottonSouthern Regional Research Laboratory, New Orleans, Louisiana
Southern Regional Research Laboratory, New Orleans, Louisiana
Southern Regional Research Laboratory, New Orleans, Louisiana Water- and alkali-soluble cotton fibers, yarns, and threads have been prepared by two methods. The cotton is preferably pretreated by pressure-kiering in 2% sodium hydroxide to remove the noncellulosic materials, and then treated with monochloroacetic acid and sodium hydroxide by either a one-step or a two-step process. Where only disintegration or partial solubility is required, the one-step method is sufficient. Where complete solubility of the cot ton is required, the process must be carried out in two steps: a mild, followed by a stronger treatment. The treated cotton is neutralized in alcohol with acetic acid to produce water soluble products or with strong acids in alcohol to produce water-insoluble but alkali-soluble products. Cotton in the form of sliver, yarn, and thread has been successfully treated.
