Claims23
An absorbent tampon comprising:
- a compressed strip of needle punched fibers having a needle punch density of at least 5 punches per cm2, the strip having a width of at least 30 mm and a length of at least 100 mm, the absorbent tampon having a tensile strength of at least 10 N or greater.
An absorbent tampon comprising:
- a compressed strip of needle punched fibers having a needle punch density of at least 5 punches per cm2, the strip having a width of at least 30 mm and a length of at least 100 mm, the absorbent tampon having a maximum to minimum tensile ratio of about 2.0 or less.
A method of forming an absorbent tampon pledget, comprising:
- needle punching a fiber web at a needle punch density of at least 5 punches per cm2;
- cutting a strip from the fiber web so as to form a tampon blank, the strip having a width of at least 30 mm and a length of at least 100 mm;
- and
- compressing the tampon blank into a shape so as to form the absorbent tampon pledget, the absorbent tampon having a tensile strength of at least 10 N or greater.
