ABSTRACT:
Fibrous structures in sheet form having from 10% to 90% by weight of pulp of cellulosic fibers cross-linked with formaldehyde, the predominant cross-linking being at the surface area of said fibers and in an amount sufficient to impart flexibility and softness to said fibers while retaining high water absorptivity, and 90% to 10% by weight of an additional binding product with the amount of the additional binding product being selected to ensure sufficient strength and cohesion to the structure of the sheet. The inclusion of the cellulosic fibers wherein the predominant amount of cross-linking is at the surface area of the fibers imparts excellent water absorptiveness to the fibrous structure and, in addition, provides good flexibility and touch and feel properties to the product.
