Abstract: A viscose multifilament yarn has a crystallinity in the range from 15% to 40%, and, after conditioning in the standard climate according to DIN EN ISO 139:2005, a yarn linear density in the range from ?150 dtex to <1100 dtex and a tensile strength in the range from ?45 cN/tex to ?55 cN/tex.

Abstract: A cord, in particular for reinforcing tyres, containing a cellulosic multifilament yarn is disclosed, where the cellulosic multifilament yarn has a strength of at least 35 cN/tex and the individual filaments of the multifilament yarn have a linear density of at least 2.3 dtex. In use, such cords exhibit a significantly improved fatigue behaviour—i.e., a significantly higher fatigue resistance—than standard cords with an individual-filament linear density between 1 and 2 dtex.

Abstract: A hybrid cord of at least two multifilament yarns twisted together is described, where the first yarn is a viscose multifilament yarn and the second yarn is a non-metallic multifilament yarn composed of a material that is not identical to the first multifilament yarn. The viscose multifilament yarn is conditioned in the standard climate in accordance with DIN EN ISO 139-1:2005, and has a yarn linear density <1100 dtex and a breaking tenacity of ?45 cN/tex. The hybrid cord has a cord linear density of ?3000 dtex.

Abstract: A process for manufacturing free-flowing pellets based on cellulosic spun fibers. The process includes a) wetting at least one cellulosic spun-fiber strand with a preferably aqueous dispersion of a polymer and/or an oligomer for the purpose of applying sizing, b) drying the at least one spun-fiber strand, and c) comminuting the at least one spun-fiber strand into pellets. The free-flowing pellets are made from at least one comminuted spun-fiber strand having sizing made from a polymer and/or an oligomer. A fiber-reinforced thermoplastic includes finely distributed free-flowing pellets for manufacturing fiber-reinforced performs.
