20130171450 | CORDS MADE OF CELLULOSIC MULTIFILAMENT YARNS HAVING AN INCREASED LINEAR DENSITY OF INDIVIDUAL FILAMENTS - 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. | 07-04-2013 |
20150322595 | HIGH-TENACITY VISCOSE MULTIFILAMENT YARN WITH LOW YARN LINEAR DENSITY - 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 139-1:2005, 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. | 11-12-2015 |
20160047069 | HYBRID CORD CONSISTING OF AT LEAST TWO MULTIFILAMENT YARNS TWISTED TOGETHER - 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. | 02-18-2016 |
