Resilient tampon and method for making
View Patent ↗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.
1. 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.
2. The method of claim 1 further comprising the step of providing absorbent fibers and further comprising the step of combining the absorbent fibers together with the binder fibers to form the loose fleece.
3. The method of claim 2 further comprising the step of cutting the loose fleece into individual units and rolling, stacking, or folding the units into blanks before compressing the blanks into pledgets.
4. The method of claim 2 wherein the activating step includes heating the loose fleece at a temperature of 240 degrees F. to 330 degrees F. and the method further includes the step of actively cooling the loose fleece after heating and before compressing.
5. The method of claim 2 wherein the absorbent fibers are viscose rayon.
6. The method of claim 2 wherein the binder fibers are bicomponent fibers.
7. The method of claim 2 wherein the loose fleece includes 80 wt % to 95 wt % absorbent fibers and 5 wt % to 20 wt % binder fibers.
8. The method of claim 2 wherein the combining step includes carding the absorbent fibers and the binder fibers to form the loose fleece.
9. The method of claim 2 wherein the combining step includes dry laying the absorbent fibers and the binder fibers to form the loose fleece.
10. 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.
11. The method of claim 10 wherein the activating step includes heating via convection.
12. The method of claim 10 wherein the combining step includes carding the viscose rayon fibers and the bicomponent binder fibers together to form the loose fleece.
13. The method of claim 10 wherein the combining step includes dry laying the viscose rayon fibers and the bicomponent binder fibers together to form the loose fleece.
14. The method of claim 10 wherein no additional external heat is applied to the pledget during the compressing step.
