Description: The availability and low cost of canola fiber make it a viable renewable resource for manufacturing value-added textile and biocomposite materials. Despite a number of studies conducted on canola fiber extraction, lack of fiber flexibility and softness necessitates further research in this area to effectively utilize canola for textiles and biocomposites. Canola fibers were extracted from stems after harvesting the seeds using water retting at 40?C and subjected to alkaline, peroxide, and enzymatic treatments. For enzymatic treatments, cellulase, amylase, pectinase, and xylanase enzymes were paired up in various combinations to identify the optimal chemical treatment, where the samples were first degummed in hot water at 90?C and then softened with an oil-in-water emulsion before being treated with enzymatic solution at pH 4.0 and 45?C and dried at room temperature. The treated samples were evaluated for softness, flexibility, and fineness. It was found that only fibers that underwent a treatment using a combination of pectinase and xylanase exhibited improved fiber softness, flexibility, and luster, while fineness data revealed a reduction in the fiber diameter as well as the fiber length. The removal of gummy substances from the fiber is believed to have refined it, which has caused the change in fiber fineness. Further, fiber individualization is maximized progressively with the advancement of processing steps. The soft and flexible canola fibers obtained after pectinase and xylanase treatment could be used for apparel and industrial applications. However, the shortening of the canola fiber?s length following chemical processing could limit its potential for spinning.
