Abstract

Long natural cellulose fibers with properties suitable for textile and composite applications have been obtained from wheat straw. This study aims to understand the potential of using wheat straw as a source for long natural cellulose fibers for textile, composite and other fibrous applications. The presence of wax on the outer layer of the straw and a unique zip-like structure that locks individual fibers makes it difficult to obtain fibers from wheat straw using the common methods of fiber extraction. A novel pretreatment with detergent and mechanical force followed by an alkaline treatment was used to obtain high quality fiber bundles. The structure and properties of the fibers are reported in comparison to common cellulose fibers, cotton, linen, and kenaf. Wheat straw fibers have coarser (wider width) single cells and lower crystallinity than cotton, linen, and kenaf. The breaking tenacity (force at break) of wheat straw fibers is similar to kenaf but lower than that of cotton and linen, % breaking elongation is similar to linen and kenaf but lower than cotton, and Young's modulus of the fibers is similar to cotton but lower than that of linen and kenaf.
