Improvements in or relating to spinnerets for use in extruding filamentary material

摘要

In a spinneret the orifices are arranged in several parallel rows so that all orifices are equally spaced by a distance at least ten times the diameter of an orifice and so that the outer orifices lie on a circle. Such spinneret is particularly for use in melt-spinning employing a transverse air blast for cooling the filaments as they emerge, the direction of the air blast being parallel to the rows of orifices for optimum cooling. Specification 533,304 is referred to.
