Title (EN) SEMI-CONTINUOUS FILAMENTS INCLUDING A CRYSTALLINE POLYOLEFIN AND A HYDROCARBON TACKIFIER RESIN, AND PROCESS FOR MAKING SAME
(FR) FILAMENTS SEMI-CONTINUS COMPRENANT UNE POLYOLÉFINE CRISTALLINE ET UNE RÉSINE TACKIFIANTE HYDROCARBONÉE, ET LEUR PROCÉDÉ DE FABRICATION
Abstract:
(EN) Nonwoven webs including one or more semi-continuous filaments made of a mixture including from about 50% w/w to about 99% w/w of at least one crystalline polyolefin (co)polymer, and from about 1% w/w to about 40% w/w of at least one hydrocarbon tackifier resin. The at least one semi-continuous filament exhibits molecular orientation, and at least one of the crystalline polyolefin (co)polymer or the nonwoven web exhibits a Heat of Fusion measured using Differential Scanning Calorimetry of greater than 50 Joules/g. A process for making the semi-continuous filaments and nonwoven webs is also disclosed.
(FR) L'invention concerne des nappes non tissées comprenant un ou plusieurs filaments semi-continus constitués d'un mélange comprenant d'environ 50 % en poids à environ 99 % en poids d'au moins un (co)polymère de polyoléfine cristallin, et d'environ 1 % en poids à environ 40 % en poids d'au moins une résine tackifiante hydrocarbonée. Le ou les filaments semi-continus présentent une orientation moléculaire, et au moins l'un du (co)polymère de polyoléfine cristallin ou de la nappe non tissée présente une chaleur de fusion mesurée par calorimétrie différentielle à balayage supérieure à 50 Joules/g. L'invention concerne également un procédé de fabrication des filaments semi-continus et des nappes non tissées.
