are disposable Chux Pads that are designed to have excellent functionality. These underpads are super absorbent and have a spunbond front sheet. This technology allows the top layer to be lighter and fluid to pass more easily through than with a solid or woven fabric, helping the fluid absorption process. These top sheets are softer and stays dryer than some other Incontinence Bed Pads. These Disposable Underpads also feature polypropylene back sheets that help to trap the moisture in the absorbent fluff layer and away from the sheets.
