摘要： An as-spun monofilament of thermotropic aromatic polyester(amide), which satisfies the following conditions: D≧40; Te>45; &Dgr;L≧0, D being its diameter (in &mgr;m), Te its tenacity (in cN/tex) and &Dgr;L 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.

摘要： Process for preparing a solution of cellulose formate from cellulose plates, in particular high-density plates, without prior mechanical destruction of these plates. The plates are dissolved directly, by means of an impregnating step of the whole plates in a base liquid of formic acid, followed by an operation of kneading of the plates thus impregnated in contact with both formic acid and phosphoric acid. The process is preferably carried out in order to prepare ready-for-spinning solutions with, in particular, if necessary, an intermediate operation of adjustment of the final composition. Solutions prepared using such a process. Preparation of objects made of cellulose, starting with these solutions, in particular fibers or films. Assemblies of such fibers or films. Articles reinforced with such fibers or films or assemblies, these reinforced articles being especially tires.
