Abstract
Ramie is a strong and lustrous bast fibre obtained from the inner bark of Boehmeria nivea (L) Gaud. The fibres are embedded in the cells of bast that lies between the outer bark and the woody core of the stem. The spinnable fibres are obtained by decOltication and degumming. It is not normally possible to spin the fibre with 20-30% adhered gum, which, therefore, needs to be removed by the process of degumming. Various methods of degumming have been reported in the literature for the removal of gums from crude ramie fibres. These include both chemical! ·3 and microbialmethods. Attempts have been made by various researchers to spin ramie in blends with jute, silk, viscose and polyester fibres using jute and woollen spinning systems-. Development of appropriate technologies for the production and processing of ramie either alone or in blends with other fibres for producing finer yarn with improved properties can widen the application of ramie fibre.
