This is the only book that provides in new direction of research in the field of natural fibre composites.Natural fibre composites are used in the form of short fibres in Engineering products. But in this research work, a natural fibre derived from the Calotropis Gigantea shrub plant is taken as continuous twisted yarn to produce length products. This book will be very helpful, to those doing research in natural fibre composites to produce continuous forms of products.Many researchers doing the work using short form of fibre to produce the products, but it lags in to produce lengthy productsThis book provides the methodology and important parameters involved while processing the fibre to fabricate the products.
