Abstract
A method of making a resilient tampon includes the steps of providing binder fibers having an average fiber length of at least 35 mm; combining the binder fibers to form a loose fleece; activating the binder fibers; and compressing a portion of the loose fleece into a pledget after activating the binder fibers. A resilient tampon includes 70 wt % to 95 wt % absorbent fibers and 5 wt % to 30 wt % bicomponent binder fibers. The binder fibers have an average fiber length greater than 35 mm.
Claims18
A method of making a resilient tampon comprising the steps of,
- providing binder fibers having an average fiber length of at least 35 mm,
- combining the binder fibers to form a loose fleece,
- activating the binder fibers, and
- compressing a portion of the loose fleece into a pledget after activating the binder fibers.
A method of making a resilient tampon comprising the steps of,
- providing viscose rayon fibers,
- providing bicomponent binder fibers having an average fiber length of at least 35 mm,
- combining the viscose rayon fibers together with the bicomponent binder fibers to form a loose fleece having 5 wt % to 30 wt % bicomponent binder fibers and 70 wt % to 95 wt % viscose rayon fibers,
- activating the bicomponent binder fibers by heating the loose fleece at a temperature of 240 degrees F. to 330 degrees F.,
- actively cooling the loose fleece after activating,
- cutting the loose fleece into individual units after cooling,
- rolling, stacking, or folding the individual units into blanks after cutting, and
- compressing the individual blanks into pledgets after rolling, stacking, or folding.
A resilient tampon comprising,
- 70 wt % to 95 wt % absorbent fibers and
- 5 wt % to 30 wt % bicomponent binder fibers, wherein the binder fibers have an average fiber length greater than 35 mm.
