Claims13
A sanitary tampon comprising an absorbent wrapped by a liquid-pervious sheet, wherein;
- the absorbent is a mass of a plurality of compressed, small fiber agglomerations, at least the small fiber agglomerations located in the peripheral region of the absorbent are bonded to each other via hydrogen bonding therebetween.
A sanitary tampon comprising an absorbent wrapped by a liquid-pervious sheet, wherein;
- the absorbent includes a web of compressed and hydrogen-bonded fibers;
- and a plurality of small fiber agglomerations contained in the web, and the small fiber agglomerations are compressed to have a higher density than the web.
A sanitary tampon comprising an absorbent wrapped by a liquid-pervious sheet, wherein;
- the absorbent includes a web of compressed and hydrogen-bonded cellulosic fibers alone or of a combination of cellulosic fibers and noncellulosic fibers all compressed and hydrogen-bonded;
- and a plurality of small fiber agglomerations of noncellulosic fibers alone or of a combination of cellulosic fibers and noncellulosic fibers to be contained in the web, and the noncellulosic fiber content of the small fiber agglomerations is higher than that of the web.
