ABSTRACT:
A method of forming a catamential tampon is disclosed which is capable of absorbing menstrual fluids. The method includes the steps of starting with an absorbent having a cross-sectional area of varying thickness. The thickest portion has a greater volume of fibers than the thinnest portion. The absorbent can be optionally enclosed with a cover. An opening is formed through the absorbent and/or cover and a withdrawal string is secured thereto. The absorbent is formed into a generally elongated, cylindrically shaped blank and then is compressed into a pledget having a zone of high density fibers and a zone of low density fibers. After compression, the zone of low density fibers will expand faster and/or to a greater extent than the zone of high density fibers, thereby forming a curved tampon. The curved tampon is rigid and self sustaining and can be used as either a digital tampon or with an applicator.
