Patent ID: 8623268

Claim:
A method for producing a filament non-woven fabric, comprising the steps of: a) obtaining filaments having a crystallization temperature not exceeding 112° C. by melting a resin containing polyphenylene sulfide as a main component which is not substantially copolymerized with trichlorobenzene; b) pulling and drawing fiber threads formed by discharging the melted resin from spinning nozzles at a spinning speed of at least 5,000 m/min and less than 6,000 m/min by an ejector disposed such that a distance between a bottom face of the spinning nozzles and a compressed air emission outlet of the ejector is 450 to 650 mm; c) collecting obtained filaments on a moving net to form a non-woven web; and d) thermocompression bonding the obtained non-woven web using a heating roller.
