Abstract
PURPOSE: Extremely fine fiber composed of ethylene terephthalate units containing a specific amount of butylene terephthalate unit is given a specific thermal property to become deeply dyeable and get soft and flexible touch.
CONSTITUTION: In the production of extremely fine fiber that has a filament denier D of less than 0.5 and is composed of ethylene terephthalate, 26W56D, preferably 65W130Dmol% of butylene terephthalate is added and the mixture is polymerized, melt spun, solidified by cooling with cooling air and drawn wherein the throughput G in g/min, cross section area of nozzle hole A in mm2 and hole density δ in hole number/cm2 satisfy equations I through III. Thus, polyester extremely fine fiber of 0.5 or less filament denier, lower then 245°C melting point, and lower than 135°C Tα at which the mechanical loss tangent tanδ becomes maximum is obtained.
