Title:
少なくとも部分的に極細であるエンドレスファイバから成る硬化された不織布を製造する方法及びこの方法にしたがって製造された不織布
Document Type and Number:
Japanese Patent JP2004527673
Kind Code:
A
Abstract:
A strengthened nonwoven is made at least in part of spun microfibers that are strengthened by hydrodynamic needling, alone or together with other fibers such as also staple fibers and/or endless fibers. The microfibers are spun from a polymer melt of only one certain polymer from a plurality of spinning apertures, and the spun filaments are drawn by gas streams accelerated to high velocity by an accelerating nozzle such as a Laval nozzle and, due to further production conditions, each fiber receives before solidification an internal hydrostatic pressure that is higher than the ambient gas pressure so that each fiber cracks in the longitudinal direction and splits up into a plurality of fine endless filaments.
