A New Method of Identifying Tencel and Model fibers Using Polarized Optical Microscope

摘要

Existing methods used to identify Tencel and Modal fibers are either inefficient or unstable. In this paper, a new physical method was proposed to identify Tencel and Model fibers quickly and accurately by using the polarized optical microscope (POM). When observed under the POM, Modal and Tencel fibers each present characteristic colors as well as their internal structures, surface morphologies and the configurations, and thus they can be identified quickly and correctly. In addition, with the help of high voltage electrostatic technology, a group of cellulose fibers can be tested simultaneously within a view. This further improves the test efficiency and makes it possible to test the blend ratio of blended cellulous fibers. The experiments have proved that it is rather easy and fast to distinguish Tencel and Model fibers from a group of cellulous fibers using the POM based method. Further more, this method is implemented by complete physical processes, thus it is truly environmental friendly.
