Abstract

Production process of synthetic yarns of asymmetric section, with respect to any axis normal to the section, by extrusion of a molten polymer through a multiple row that includes at least two elementary orifices unequal to each other, whose process is characterized by extrusion of the polymer through the said holes of a certain length of passage, and fed with molten polymer of determined viscosity and pressure, the A/B ratio being between 1 and 4, in which ratio A and B indicate the respective values of Β 2/α higher and lower, respectively, than the isolated holes in the row, representing Β the hydraulic radius of the hole and α a coefficient of form of it.
