Regenerated Cellulose Fibers Using Unconventional Cellulosic Sources
Apart from using conventional sources of cellulose such as wood, nonconventional resources such as sugarcane bagasse, bamboo, and bacteria have also been used to produce regenerated cellulose fibers. Viscose fibers with a linear density of 17 tex and length between 1.7 and 38 mm obtained from eucalyptus wood were modified with alkali solutions to improve the adhesive and surface properties [13Roj]. After treating with various concentrations of alkali, about 10–12 % decrease in % crystallinity was observed. Increase in diameter of fibers and decrease in contact angle after alkali treatment were also seen [13Roj].
