Publication number: 20220136139Abstract: A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a static splitting profile having a row of teeth, e.g., with a cutting edge extending in the process direction. The tape is split to form a material comprising a plurality of parallel strips interconnected by fibrils. The split material can for example be used for the production of high tensile ropes or laminates.Type: ApplicationFiled: November 17, 2021Publication date: May 5, 2022Applicant: TEIJIN ARAMID B.V.Inventors: Edo MUGGE, René JOURNÉE

Patent number: 9194061Abstract: A para-aramid fibrid film is disclosed that has at least 95% of the bonds of the polymer are para-oriented. A method for making said para-aramid fibrid film by (a) polymerizing a para-oriented aromatic diamine and a para-oriented aromatic dicarboxylic acid halide to an aramid polymer having only para-oriented bonds in a mixture of solvents consisting of N-methylpyrrolidone or dimethylacetamide and calcium chloride or lithium chloride to obtain a dope wherein the polymer is dissolved in the mixture of solvents and the polymer concentration is 2 to 6 wt. %, and (b) converting the dope to para-aramid fibrid film is also described.Type: GrantFiled: November 30, 2004Date of Patent: November 24, 2015Assignee: TEIJIN ARAMID B.V.Inventors: Anton Johannes Josef Hendriks, Dennis Wilbers, Harrie Grotendorst, René Journee, Mirjam Ellen Oldenzeel

Patent number: 8415417Abstract: The invention relates to a non-fibrous polymer solution essentially consisting of 1 to 8 wt. % para-aramid, at least 50 mole % of the aromatic moieties thereof being unsubstituted, in a mixture of a) a polar amide solvent selected from N-methyl-2-pyrrolidone, N,N?-dimethylformamide, N,N?-dimethylacetamide, tetramethylurea, and mixtures thereof; b) between 0.7 mole of an alkali or earth alkali chloride per mole amide groups of the para-aramid and 7.5 wt. % of the alkali or earth alkali chloride, and c) water; and wherein at least 50 wt. % of the formed hydrochloric acid has been neutralized to obtain a solution having a dynamic viscosity which is at least a factor three smaller than the dynamic viscosity of the polymer solution without neutralization. The invention further pertains to a process making the same and para-aramid pulp-like fiber, paper and film made from said polymer solution.Type: GrantFiled: May 28, 2010Date of Patent: April 9, 2013Assignee: Teijin Aramid B.V.Inventors: Anton J.

Patent number: 7629047Abstract: Aramid fibrils having in the wet phase a Canadian Standard Freeness (CSF) value less than 100 ml, after drying a specific surface area (SSA) less than 7 m2/g, and a weight weighted length for particles having a length >250 ?m (WL 0.25) less than 1.2 mm, are described. A method of preparing the fibrils includes the steps (a) polymerizing an aromatic diamine and an aromatic dicarboxylic acid halide to an aramid polymer, in a mixture of N-methylpyrrolidone or dimethylacetamide and calcium chloride or lithium chloride to obtain a dope wherein the polymer is dissolved in the mixture and the polymer concentration is 2 to 6 wt. %, (b) converting the dope to fibrils by using a jet spin nozzle under a gas stream, and (c) coagulating the fibrils using a coagulation jet.Type: GrantFiled: November 30, 2004Date of Patent: December 8, 2009Assignee: Teijin Aramid B.V.Inventors: Anton Johannes Josef Hendriks, Jan Davis Cornelis Tiecken, Harrie Grotendorst, René Journee, Mirjam Ellen Oldenzeel
