IPC: D02J1/00
Filed: 1992-02-25
Abstract: PURPOSE:To obtain the subject yarn having fine, random and natural appearance of thick parts by melt spinning a polyester, taking off the resultant yarn, subjecting the taken off undrawn yarn to yarn interlacing treatment between specifically arranged rollers and then drawing the yarn at a low draw ratio. CONSTITUTION:For example, a polyester in which >=90% constituent units are polyethylene terephthalate is melt spun and taken off from a spinneret 1. An oiling agent is then applied to the resultant yarn with an oiling roller 2 and the oiled yarn is then taken off with a take-off roller 3 arranged between the oiling roller 2 and the first godet roller 5 at a prescribed speed. The undrawn yarn is subjected to interlacing treatment with an interlacing nozzle 4 installed between the take-off roller 3 and the godet roller 5 and further drawn between the first godet roller 5 and the second godet roller 6 at a low draw ratio to afford the objective yarn.
