Abstract
The present invention relates to absorbent materials comprising fibers cross-linked by a suitable heat activatable compound therefor, and wherein said heat activatable compound is associated with substantially the entire surface of each fiber, said materials being preparable by mixing of an aerated suspension of the charged fibers with the heat activated compound before heating and compressing, such fibers having a capacity for fluid absorption considerably greater than has been heretofore known for such materials.
