Hollow irregular multifilament yarn and process and spinneret for producing the same |
| abstract |
A synthetic polymer hollow irregular multifilament yarn useful for producing bulky yarn products comprises a plurality of hollow irregular individual filaments each comprising a hollow filamentary constituent, a non-hollow sinuous filamentary constituent sinuously extending in a wave form along the hollow filamentary constituent, having a smaller average thickness than the hollow filamentary constituent and being connected to one side of the hollow filamentary constituent through a middle filamentary constituent distortedly extending along the hollow filamentary constituent and having a cross-sectional profile in the form of a waist, and is produced by extruding at least one polymer melt through a spinneret having a plurality of spinning orifices each consisting of a first orifice segment adequate for forming a hollow filament, a second orifice segment adequate for forming a non-hollow filament and having a smaller cross-section than that of the first orifice segment and a third orifice segment in the form of a slit connected to both the first and second orifice segments, by cooling the extruded hollow irregular filamentary streams to solidify them and by taking up the resultant hollow irregular multifilament yarn. |
