Abstract

PURPOSE: An extremely fine multifilament yarn is made by melt spinning at a high speed, cooling, oiling collecting and taking up with a specific tension, thus reducing the wrapping of broken filaments around rollers to the minimum to produce the objective extremely fine multifilament yarn.
CONSTITUTION: In the production of extremely fine multifilament yarn with a filament fineness of lower than 2 denier by melt spinning at a speed of 600W1,500m/ min, the yarn 2 extruded from the spinneret 1 is solidified by cooling with the cooling means 3, oiled with the oil applicator equipped with a collecting guide 4 and collected. Then, when the yarn, after running through chimney 5, is taken up with rollers 7 and 8, the take-up tension A at the starting point of the roller is adjusted to less than 50% of the yield stress X in the stress-strain curve of the undrawn yarn and the yarn is wound up into a package 9.
