Abstract
Disclosed is a modified cellulose fiber having improved curl characteristics. Specifically, the present invention relates to oxidized or sulfonated cellulose fibers being highly curled, wherein such curl is highly stable. The oxidized or sulfonated curled cellulose fiber may be prepared by a process comprising treating the fibers in a high energy refiner effective to provide the desired curl properties to the fiber. The modified cellulose having improved curl characteristics may be used in disposable absorbent products.
Claims12
An oxidized cellulose fiber exhibiting a Curl Factor value that is at least about 6.
A sulfonated cellulose fiber exhibiting a Curl Factor value that is at least about 6.
A process for treating an oxidized cellulose fiber, the process comprising treating an oxidized cellulose fiber in a refining means wherein the refining means is operated at a power input of greater than about 2 horsepower-day per ton of oxidized cellulose fiber, wherein the treated oxidized cellulose fiber exhibits a Curl Factor value that is at least about 6.
A process for treating a sulfonated cellulose fiber, the process comprising treating an sulfonated cellulose fiber in a refining means wherein the refining means is operated at a power input of greater than about 2 horsepower-day per ton of sulfonated cellulose fiber, wherein the treated sulfonated cellulose fiber exhibits a Curl Factor value that is at least about 6.
