Abstract

Mezcla de fibras de copoliéster de sección transversal en general oval festoneada con estrías que discurren a lo largo de las fibras, siendo dicho copoliéster teñible con colorantes catiónicos en virtud de la presencia de aproximadamente un 1 a aproximadamente un 2, 5 % molar de una sal de metal alcalino de un ácido 5-sulfónico isoftálico, y siendo la cadena de dicho copoliéster ramificada con un porcentaje de aproximadamente un 0, 05 a aproximadamente un 0, 8 % molar de ramificador de cadena, y siendo dicha mezcla una mezcla de fibras que tienen un denier superior por filamento y de fibras que tienen un denier inferior por filamento, siendo dicho denier superior por filamento al menos 1, 2 veces dicho denier inferior por filamento.Mixture of copolyester fibers of generally oval cross section scalloped with grooves that run along the fibers, said copolyester being dyeable with cationic dyes by virtue of the presence of about 1 to about 2.5 mole% of a salt of alkali metal of an isophthalic 5-sulfonic acid, and the chain of said branched copolyester being with a percentage of about 0.05 to about 0.8 mol% of chain branching, and said mixture being a mixture of fibers that they have an upper denier per filament and fibers having a lower denier per filament, said upper denier per filament being at least 1, 2 times said lower denier per filament.
