Abstract

The paper describes an automated method of determining the width of cellulosic fibers, including in the course of their treatment by various reagents. This method is based on microscopy of individual fibers and subsequent treatment of obtained photos and video files with the help of specially designed software. The study of cellulose fibers swelling is of great theoretical and practical importance. The method allows us to film cellulose fibers swelling in various reagents, including strong solutions of mineral acids and alkalis. We compared the fiber width measurements taken by the proposed method with those obtained by the widely used L&W Fiber Tester. Fiber distributions by the width turned out to have similar configuration. The advantage of the proposed method is that it allows us to study fiber swelling in various solvents, both organic and inorganic, while L&W Fiber Tester cannot be used with aggressive chemicals. The method allows us to monitor dynamic changes in the fiber structure and can help determine such parameters as the width of cellulose fibers and the degree, rate and shape of their swelling when treated with acids, alkalis and enzymes.
