Influence of ozone pre-treatment on enzyme hydrolysis of jute fibrous wastes for reinforcement in composites

Original language description

The chapter focuses on the development of environment friendly approach for surface treatment of jute fibers and subsequent separation of individual cellulose micro crystals. The sequential action of ozone pre-treatment followed by enzyme hydrolysis was selected for this purpose. The effect of pre-treatments on mechanical properties of jute fibers was investigated. The maximum deterioration in mechanical properties was found in case of ozone treated jute fibers than 48 chemically treated jute fibers. The rate of refinement of untreated fibers having non-cellulosic contents was found slower than treated jute fibers due to strong holding of fiber bundles by non-cellulosic contents. This indicated easier separation of individual micro crystals after ozone pre-treatment. The improvements in mechanical properties are attributed to their rough uneven surface, higher percentage of cellulosic contents and smaller particle size. The present study showed a green process for reusing of waste jute fibers and converting them into useful cellulose powder for reinforcement in composite materials. Moreover, the ozone treatment was found attractive in terms of less energy, time and water with additional advantage of minimum degradation of cellulose. The current book is the THIRD in a series of manuscripts under “PROGRESS IN FIBROUS MATERIAL SCIENCE”. These books are collection of chapters dealing with state of the art technologies and the science of polymeric materials in specific.
