Abstract

A process for producing an absorbent article is provided. The process comprises placing an absorbent layer between a body-side, cover layer and a fluid-impermeable, garment-side backing layer wherein the cover layer and the absorbent layer are each comprised of thermoplastic fibers. The cover layer, absorbent layer, and backing layer are subjected to pressure and heat sufficient to melt only one of the thermoplastic fibers in each of the cover and absorbent layers.

Claims

1. A process for producing an absorbent article comprising the steps of:

a. placing an absorbent layer between a body-side, cover layer and a fluid impermeable, garment-side backing layer wherein the cover layer and the absorbent layer are each comprised of thermoplastic fibers and

b. subjecting the cover layer, absorbent layer, and backing layer to pressure and heat sufficient to melt only one of the thermoplastic fibers in each of the cover and absorbent layers.

2. The process of claim 1 wherein the temperature of the pattern roll is in the range of from about 200°

F. to about 400°

F. and the temperature of the anvil roll is in the range of from about 100°

F. to about 200°

F.

3. The process of claim 1 wherein the pressure is in the range of 100 to about 600 psi.
