发明名称 Compressible wood pulp product
摘要 A highly densifiable wood pulp product is disclosed. In one embodiment, the densifiable product includes fibers having low coarseness, preferably having a fiber coarseness less than about 22 mg/100 m, and a densifying agent. In another embodiment, the densifiable product further includes fibers having coarseness greater than about 22 mg/100 m. Juvenile wood fibers are the preferred source of fibers having low coarseness. A densified pulp product formed by compacting a fibrous composite that includes fibers having a fiber coarseness less than about 22 mg/100 m, a densifying agent, and optionally, fibers having coarseness greater than about 22 mg/100 m is also disclosed. The pulp products can be advantageously incorporated into absorbent articles and can optionally further include superabsorbent material. Methods for forming the densifiable and densified fibrous products are also disclosed.
