摘要

Process for the use and transformation of hemp waste and the like, to convert them into spinnable fibers of properties analogous to those of cotton, essentially characterized by comprising a treatment on the fibers or waste of hemp, linen, jute, ramie, broom or other similar vegetables, which comprises a deglowing or lejiaciºn to achieve a previous emulsion of the fats and waxes that said materials contain, following this treatment a bleaching phase, operating for the liquor with a minimum degradation to avoid losses of resistance, and either by hydrolysis or oxidation, working in circulation autoclave, in which fats and waxes are solubilized, using as an active liquor a soda lye, to which is added, rosin, soap and sodium carbonate, varying the proportions of these elements in function of the type of fiber to be treated.
