Title
(EN) POLYSACCHARIDE FIBERS
(FR) FIBRES DE POLYSACCHARIDE
Abstract
(EN)
This invention pertains to novel fibers made of $g(a)(1$m(7);3) polysaccharides, and a process for their production. The fibers of the invention have 'cotton-like' properties but can be produced as continuous filaments on a year-round basis. The fibers are useful in textile applications.
(FR)
L'invention concerne de nouvelles fibres obtenues à partir de polysaccharides $g(a)(1$m(7);3), ainsi que leur processus de production. Les fibres de l'invention présentent des propriétés proches de celles du coton mais elles peuvent être produites sous forme de filaments continus tout au long de l'année. Ces fibres conviennent dans des applications textiles.
