Abstract
An improved knot for attachment of withdrawal cords to tampons is provided. The knot comprises at least two closed loops around a portion of a length of absorbent material. The standing parts of the cord cross at least twice, to form a crossed portion at the base of the loops; a loop portion overlies the crossed portion when the knot is in place around the absorbent material, applying pressure to the crossed portion when the knot is tightened. The invention also features a process for forming the knot.
