摘要： PROBLEM TO BE SOLVED: To efficiently provide filament nonwoven fabric of high isotropism.
SOLUTION: A method for producing the filament nonwoven fabric is provided, comprising the following process: Filaments are first produced, having such a structure as to be divisible into two or more kinds of filaments, wherein at least one kind thereof is thermoshrinkable. Just after spun, the above filaments are collected and laminated on a net, and then interlaced and mechanically divided and thereafter subjected to hot water shrinkage. The above steps are consecutively and successively conducted. It is preferable that the single filament fineness of the filaments after divided be 0.5-0.001 dtex and the polymers constituting the filaments be a polyester and a polyamide. Furthermore, it is preferable that the hot water shrinking step comprise catching the filament nonwoven fabric immersed and floating in hot water on a water-permeable substrate and water in the nonwoven fabric be continuously removed following the hot water shrinking step.
