  • Patent number: 4179259
    Abstract: The present invention relates to production of wool-like chemical filaments and, more particularly, to a spinneret for obtaining these filaments. The present invention is most effectively realized in the production from these filaments of household and industrial textiles. This spinneret includes a filament-forming hole made as a slot with a configuration of an open polygon, having a rectilinear portion adjoining one of the sides thereof and one more element shaped as a rectilinear section adjoining this portion at a right angle thereto. Such a structure of the spinneret permits production of a wool-like filament possessing all properties inherent in natural wool, namely, low heat conductivity, permanent crimp, and high hygienic properties.
