ABSORBENT FIBER WITH A LOW ABSORBENT CAPACITY AND SLOW ABSORPTION RATE

An absorbent fiber includes a cellulose fiber that has been modified via chemical modification, where the chemical modification is selected from carboxymethylation, sulfonation, sulfation or phosphonation. The absorbent fiber can be substantially water-insoluble and water-swellable. The absorbent fi...

More Information
Summary:An absorbent fiber includes a cellulose fiber that has been modified via chemical modification, where the chemical modification is selected from carboxymethylation, sulfonation, sulfation or phosphonation. The absorbent fiber can be substantially water-insoluble and water-swellable. The absorbent fiber exhibits a Centrifuge Retention Capacity after four hours of between 1.4 and 8 grams per gram and an absorption rate between 0.0001 and 0.01 sec-1. Absorbent articles having a topsheet, a backsheet and an absorbent core can also include the absorbent fiber.
