摘要: There is described a tampon made of continuous filaments based on a man-made fiber tow with a water-holding capacity of at least 1000% by weight, the tampon consisting essentially of continuous filaments in a perpendicular arrangement relative to the longitudinal axis of the tampon with essentially only one free filament end at the surface per filament while the other free filament end is on the inside.
