Abstract
Procédé pour préparer des filaments ou fibres hydrophiles en polymères de l'acrylonitrile par filage à sec ou au mouillé d'une solution du polymère dans un solvant non aqueux et formation éventuelle de la fibre par évaporation du solvant dans un puits ou par précipitation dans un bain aqueux avec étirage et lavage subséquents. On ajoute à la solution de filage, par rapport au polymère, de 1 à 100 %, de préférence de 5 à 50 %, de composés pris dans les classes de substances ci-après : polyamides, alcool polyvinylique, polyamines, polyuréthannes, polycarbamates, polystyrène, oxyde de polypropylène, acétate de polyvinyle ou copolymères à bas poids moléculaire de tels oligomères, ou encore esters et éthers cellulosiques et/ou dérivés de l'amidon, présentant un poids moléculaire d'au moins 2 000 et de 10 000 au maximum. Les filaments hydrophiles obtenus conformément à l'invention ont une structure microporeuse exempte d'espaces creux de grandes dimensions, d'où des propriétés mécaniques intactes.Process for preparing hydrophilic filaments or fibers of acrylonitrile polymers by dry or wet spinning of a solution of the polymer in a non-aqueous solvent and possible formation of the fiber by evaporation of the solvent in a well or by precipitation in a aqueous bath with subsequent drawing and washing. Is added to the spinning solution, relative to the polymer, from 1 to 100%, preferably from 5 to 50%, of compounds taken from the classes of substances below: polyamides, polyvinyl alcohol, polyamines, polyurethanes, polycarbamates, polystyrene, polypropylene oxide, polyvinyl acetate or low molecular weight copolymers of such oligomers, or cellulose esters and ethers and / or starch derivatives, having a molecular weight of at least 2000 and at most 10,000 . The hydrophilic filaments obtained in accordance with the invention have a microporous structure free from hollow spaces of large dimensions, hence intact mechanical properties.
