Identification of cellulose acetate fiber based on the testing of esterification degree
Based on the classification of cellulose acetate fiber and its principle of deacetylation under alkaline conditions,the esterification degree was tested by acid-base titration.At the same time,the conventional dissolution and melt-ing point tests were used to verify.For some partially saponified cellulose ac-etate fibers and some cellulose acetate fibers with critical esterification degree that are not completely consistent with the current standard of diacetate fiber and triacetate fiber,the test results can avoid the interference of external char-acter changes and be more accurate and reliable.
