A cellulose acetate fiber having excellent gloss and hand and comprising a mixture consisting essentially of (a): 100 parts by weight of cellulose acetate with (b) 5 to 40 parts by weight of a polymer material capable of plasticizing the cellulose acetate, wherein the section perpendicular to the longitudinal direction (i) is noncircular, (ii) has one to four symmetrical axes, and (iii) has a peripheral section defined by a gentle curve or a combination of a gentle curve with a straight line. The fiber can be prepared by dry-spinning a spinning solution consisting essentially of: (a) 100 parts by weight of cellulose acetate, (b) 5 to 40 parts by weight of a polymer material which is soluble in solvents and can plasticize the cellulose acetate, and (c) a solvent capable of dissolving the components (a) and (b).
Fibre d'acétate de cellulose possédant un lustre et un toucher excellents et composée d'un mélange constitué essentiellement par: (a) 100 parties en poids d'acétate de cellulose avec (b) 5 à 40 parties en poids d'un matériau polymère capable de plastifier l'acétate de cellulose, la section perpendiculaire au sens de la longueur étant (i) non circulaire et possédant (ii) un à quatre axes symétriques et (iii) une section périphérique définie par une courbe légère ou par une combinaison d'une courbe légère et d'une ligne droite. On peut préparer cette fibre par filage à sec d'une solution de filage constituée essentiellement par: (a) 100 parties en poids d'acétate de cellulose, (b) 5 à 40 parties en poids d'un matériau polymère soluble dans des solvants et pouvant plastifier l'acétate de cellulose et (c) un solvant capable de dissoudre les constituants (a) et (b).
