Abstract

L'invention concerne les fibres creuses d'acétate de cellulose. Elle se rapporte à des fibres formées à partir d'une composition contenant environ 41 à 50 % d'acétate de cellulose, 2 à 20 % de glycérine et 30 à 57 % de polyéthylèneglycol. Ces fibres sont refroidies, étirées à froid avant retrait des plastifiants et nouvelle plastification par de la glycérine. Application aux fibres semi-perméables des reins artificiels.The invention relates to hollow fibers of cellulose acetate. It relates to fibers formed from a composition containing about 41 to 50% cellulose acetate, 2 to 20% glycerin and 30 to 57% polyethylene glycol. These fibers are cooled, cold drawn before removal of the plasticizers and new plasticization with glycerin. Application to semi-permeable fibers of artificial kidneys.
