Abstract
PURPOSE: Polyester multifilaments that are mainly made of ethylene terephthalate, have cross sections, which is folded and at least one of which leads to the outside, with a specific cross section modification ratio, an alkali weight reduction ratio and a specific intrinsic viscosity, thus showing good antisnagging properties.
CONSTITUTION: A linear polyester containing more than 85% recurring units of ethylene terephthalate is melt-spun through noncircular spinning nozzles. At this time, the spinning temperature is set so that the drawn fiber has a strength at break of 60W85% the maximum strength at break, when it is drawn in a usual manner so that the elongation becomes 30% at break. Then, the fiber is drawn and false twisted. Thus, filaments with a folded cross section, at least one leading to the outside and a cross section modification ratio of more than the value of the formula (d is the filament denier) are obtained. The resultant filaments are contained in a yarn so that the filament count becomes more than 30% to produce a polyester multifilament yarn with more than 12wt% weight reduction on the treatment with 50g/l aqueous sodium hydroxide at 90°C for 30min.
