Investigation Of Biodegradable Nonwoven Composites Based On Cotton, Bagasse And Other Annual Plants, Xiaoqun Zhang

LSU Master's Theses

In this study a new method of preparing biodegradable all-cellulosic composite nonwoven materials composed of cotton and kenaf or cotton and bagasse has been developed. Alkaline extracted kenaf or bagasse fibers were used as the main component of composite nonwovens. Recyclable or low value cotton fibers were used to entangle coarser kenaf or bagasse fibers in a web on which the nonwoven architecture was based. The novel adhesive system developed in this work for the web bonding was cellulose from a solution, in N-methyl morpholine N-oxide monohydrate. The completely biodegradable composite nonwovens were obtained by sandwiching and hot-pressing the cellulosic …
