Physical properties of Fabrics. The fibers are made into fabric three different ways. The cotton fibre is an elongated cell, constructed from millions of cellulose molecules. Google Scholar Physical Properties of CottonThe three cotton fiber properties most often considered in nonwoven applications are micronaire, length and strength. Cellulose is a polymer of ß-D-glucose with a specific configuration shown in figure. Their strength ranges from 9 gm to 13 gm per fibre. The cellobiose, repeating unit of cellulose, consist of two beta glucose molecules linked together at the 1:4 carbon atoms. 4.2 This test method describes acceptable practices for testing of raw cotton using cotton classification instruments that are capable of testing the fiber properties of micronaire reading, length, uniformity index, strength, Rd (color), +b (color), percent area (trash) and particle count (trash). Cellulose is a macromolecule made up of anhydroglucose unit connected by 1, 4 oxygen bridges with the polymer repeating unit being anhydro-beta-cellulose.
