Method for making a disposable garment having softer waist and leg cuffs
The present invention provides a method of achieving low tension, highly conformable elasticized areas in a nonwoven web construction such as may be suitable for the waistbands or leg openings of disposable absorbent pant garments, cuffs on sleeves of medical garments, or the like. A web, or webs, of nonwoven material which make up the substrate for the elasticized area are provided to be very light weight and flexible and provide the minimal amount of substrate to which an elastomeric liquid barrier material is affixed. The absorbent, or liquid retention, section of an absorbent garment article made according to the present invention will have its own barrier layer facing the backsheet, in order that the backsheet may be composed of a light and conformable material.
1. A method of making an absorbent personal care product comprising:
a) supplying a retention-barrier composite web having an absorbent material adhered to a liquid barrier sheet and cut to individual product lengths;
b) providing a soft and flexible backsheet;
c) adding soft and flexible waist elastics to the backsheet;
d) adding soft and flexible leg elastics to the backsheet;
e) coating the construction of steps b)-d) with adhesive and adhering the retention-barrier composite web substantially between the waist and leg elastics to the backsheet;
f) adhering a fluid distribution layer over and within the central portion of the retention-barrier composite web;
g) adhering a soft and flexible topsheet over the construction of steps a)-f) to create a precursor product web; and
h) cutting the precursor product web into individual absorbent personal care products.

22. A method of making an absorbent personal care product comprising, the steps, in the order stated, of:
a) creating a retention-barrier composite web on a first component line by:
i) wrapping a fluff pad in tissue forming a continuous retention web;
ii) feeding an extendible, vapor-permeable, liquid barrier sheet material into the first component line;
iii) adhering a spacer layer on the barrier sheet;
iv) laminating the retention web to the spacer layer thereby creating a retention-barrier composite web;
v) cutting leg openings in the retention-barrier composite web; and
vi) cutting the retention-barrier composite web to individual garment lengths;
b) creating a precursor product web on a conversion line by:
i) feeding a soft and flexible backsheet into the conversion line, the backsheet being elastic or extensible;
ii) adding soft and flexible waist elastics to the backsheet;
iii) adding soft and flexible leg elastics to the backsheet;
iv) coating the construction of steps i)-iii) with adhesive and adhering the retention-barrier composite web thereto;
v) adhering a fluid distribution layer over and within the central portion of the retention-barrier composite web;
vi) adhering a soft and flexible topsheet over the whole construction of steps i)-v), the topsheet being elastic and extensible;
vii) cutting leg holes in the backsheet and the topsheet and leaving said leg elastics adjacent the leg holes; and
viii) cutting the precursor product web into individual absorbent personal care products.
23. An absorbent personal care product consisting of:
a) a retention-barrier composite web having an absorbent material adhered to an extendible vapor-permeable, liquid barrier sheet and cut to individual product lengths;
b) an extendible soft and flexible backsheet having soft and flexible waist elastics adhered to the backsheet and tensioned soft and flexible leg elastics adhered to the backsheet;
c) the retention-barrier composite web adhered to the backsheet in an area between the waist elastics and the leg elastics;
d) a fluid distribution layer adhered over and within the central portion of the retention-barrier composite web; and
e) an extendible soft and flexible topsheet adhered to the soft and flexible backsheet and covering the retention-barrier composite web, the fluid distribution layer, the waist elastics and the leg elastics.
24. The absorbent personal care product of claim 23 further consisting of the retention-barrier composite laying entirely between the leg and waist elastics.
25. The absorbent personal care product of claim 24 further consisting of containment flaps.
