Abstract (en)
The present invention relates to modified linen slivers and yarns characterized by increased crease resistance while maintaining the allomorph I content, the strength and the beautiful appearance of the natural fibers. In particular, the cross-linked linen slivers and yarns according to the invention have an allomorph I content measured by solid state <13>C NMR of at least 40%, preferably at least 45%, and a solubility in cuproethylendiamine (Cued) 0.5 M lower than 1.4 g/l. The low solubility in Cued indicates the presence of cross-linking between cellulose chains which is stable to the strong basic conditions of Cued.
