Abstract

The invention aims at providing a polyester fiber for air-laid nonwoven fabrics which is extremely excellent in air-laid web formability, particularly in the ejection of fibers from a screen and which enables the production of bulky air-laid nonwoven fabrics having excellent texture. The aim is attained by a process for the production of a polyester fiber for air-laid nonwoven fabrics which has either a fineness of 10dtex or below or a fiber length of 8mm or above and exhibits a number of crimp of 8.5 waves per 25 mm or above, a ratio of percentage of crimp to number of crimp of 0.65 or below, a crimp modulus of elasticity of 70% or above and which contains as the fiber-forming resin component a polyester wherein alkylene terephthalate repeating units account for at least 80 mole% of all the repeating units, which process comprises subjecting unstretched polyester filaments taken off at a spinning speed of 1500 m/min or below to both stretching at a low stretch ratio of 0.60 to 1.2 and at a temperature higher than the glass transition temperature of the polyester by 10 DEG C or above and fixed-length heat treatment simultaneously.
