Abstract

1324832 Crimped polyester filaments MITSUBISHI RAYON CO Ltd 18 March 1971 7190/71 Heading B5B A method for producing crimped composite polyester filaments comprises drawing undrawn composite polyester filaments obtained by composite spinning of two polyesters differing in their intrinsic viscosity (measured using a solvent mixture of 50% by weight each of dichloroethane and phenol at 35‹ C.) by at least 0À03 in eccentric or side by side relation at a drawing ratio of 0À75 to 0À95 times the maximum drawing ratio at a temperature of 60 to 120‹ C. and heat setting the filaments at a heat setting temperature (T) of 120 to 200‹C., and subsequently continuously heat relaxing at a temperature of (T-80)‹ C to (T-20)‹ C. while maintaining an overfeed percentage higher than heat shrinkage percentage of the filaments at said temperature. The polyesters used for example those obtained from lower dialkyl esters (i.e. having 1 to 5 C atoms in the alkyl group) of terephthalic acid and ethylene glycol or terephthalic acid and ethylene glycol or terephthalic acid and alkylene oxide or those in whichat least 80% of repetition units is ethylene terephthalate. Illustrative of the third component are dicarboxylic acids, lower alkyl esters thereof, and glycols. The drawing and the heat setting may be carried out in one stage by drawheat setting system in which a pin and a plate are provided between a feeding roll and drawing roll and heat relaxing is carried out by fluid jet of heated air or steam or combination of these or where the drawing and the heat setting are carried out in two separate stages and heat setting is carried out with redrawing at a draw ratio of 1À0 to 1À2. The crimped polyester filaments produced by this method have an excellent dye-evenness.
