A cellulosic fibrous aggregate formed from sections of cellulosic fibrous material by a process which comprises: a softening stage comprising softening a plurality of sections of cellulosic fibrous material by the action of an aqueous softening agent at elevated temperature, thereby at least partially breaking down the cellulosic cross-linking in the cellulosic fibrous material; a compression stage comprising pressing together the softened sections of cellulosic fibrous material to form a compressed matrix; and a consolidation stage comprising dewatering and consolidating the compressed matrix to form a consolidated matrix, and a process for its preparation comprising the aforementioned softening, compression and consolidation stages.
A cellulosic fibrous aggregate formed from sections of cellulosic fibrous material by a process which comprises:
A cellulosic fibrous aggregate prepared by softening a plurality of sections of cellulosic fibrous material at least 20 cm long by the action of an aqueous softening agent at elevated temperature from about 50.degree. C. to about 150.degree. C., thereby at least partially breaking down the cellulosic cross-linking in the cellulosic fibrous material, compressing together the softened sections of cellulosic fibrous material to form a compressed matrix, and dewatering and consolidating the compressed matrix to form a consolidated matrix.
A process for the preparation of a cellulosic fibrous aggregate from sections of cellulosic fibrous material, which process comprises the steps of:
