Title:
【発明の名称】サーモトロピック芳香族ポリエステル(アミド)モノフィラメント
Document Type and Number:
Japanese Patent JP2002503295
Kind Code:
A
Abstract:
An as-spun monofilament of thermotropic aromatic polyester(amide), which satisfies the following conditions: D>=40; Te>45; DELTAL>=0, D being its diameter (in mum), Te its tenacity (in cN/tex) and DELTAL its variation in length (in %) after 2 minutes at 235±5° C. at an initial tension of 0.2 cN/tex. A spinning process for obtaining such a monofilament, including, upon emergence from the spinneret, of structuring the flow of the polymer by stretching in a layer of gaseous fluid for a predetermined time which is a function of the diameter D, before thermally quenching the flow of polymer thus structured in a liquid, so as to solidify it.
