摘要： Disclosed is a production method which can yield a filament non-woven fabric with polyethylene sulfide as a main component, in which irregular width shrinkage, wrinkling, or surface irregularity due to heat contraction during thermocompression bonding of a non-woven fiber web do not occur. This is achieved by a simplified step in which stretching treatment under heating and/or heat treatment under tension are not performed on a non-woven web or fabric. The disclosed production method for a filament non-woven fabric comprises a) a step yielding filaments having a crystallization temperature not exceeding 112°C, in which a resin having polyethylene sulfide as a main component is melted, and fiber threads ejected from spinning nozzles are pulled and drawn at a spinning speed of at least 5, 000 m/min and less than 6, 000 m/min by an ejector, which is disposed such that the distance between the bottom face of the spinning nozzles and the compressed air emission outlet of the ejector is 450 - 650 mm; b) a step which collects the obtained filaments on a moving net, forming a non-woven web; and c) a step which performs thermocompression bonding on the obtained non-woven web using a heating roller.
