Publication number: 20140147616Abstract: The invention relates to a regenerated cellulose fiber (1?) the cross-section of which comprises an oblong, essentially flat section (3). The fiber according to the invention is characterized in that at least one limb (4, 5, 6, 7) branches off from the oblong section, wherein the length of said limb is at most 40% of the length of the oblong section (3).Type: ApplicationFiled: June 26, 2012Publication date: May 29, 2014Applicant: KELHEIM FIBRES GMBHInventors: Ingo Bernt, Matthew North, Reinhold Röthenbacher, Walter Roggenstein, Roland Scholz
