| description | To provide a manufacturing method of a nonwoven fabric which can more finely fibrillate filaments composing the nonwoven fabric without excessively increasing pressure and temperature of high pressure air in a drawing process and without the occurrence of end breakage.SOLUTION: A manufacturing method of a nonwoven fabric 5 includes: spinning processes 11, 12, 20; a cooling process 30; and a drawing process 40. In the drawing process, a space S between slits is defined as 0.3 to 0.6 (mm), air quantity per unit length of a slit 42c is defined as 1000 to 3000 (m3/h/m), and a temperature of high pressure air is defined as 30 to 60 (°C). As a result, tractive force to a filament aggregate 3 caused by an injection air flow is increased, a "fiber diameter of a filament" can be relatively thinned (9 to 13 (μm)), and "evaluation of end breakage difficulty" and "fabric uniformity" can be improved with good balance.SELECTED DRAWING: Figure 2
【課題】延伸工程における高圧エアーの圧力や温度を過度に高めることなく、糸切れを生じさせずに、不織布を構成するフィラメントをより細繊化することができる不織布の製造方法を提供する。【解決手段】不織布５の製造方法は、紡糸工程１１，１２，２０と、冷却工程３０と、延伸工程４０と、を備え、延伸工程において、スリットの間隔Ｓを０．３～０．６（ｍｍ）とし、スリット４２ｃの単位長さ当たりの風量を１０００～３０００（ｍ3／ｈ／ｍ）とし、高圧エアーの温度を３０～６０（℃）とすることにより、噴射気流によるフィラメント集合体３への牽引力を大きくし、「フィラメントの繊維径」を比較的細くすること（９～１３（μｍ））ができるとともに、「糸切れ難さの評価」及び「地合の均一性」をバランス良く向上させることができる。【選択図】図２ |
