Abstract
The difficulties in using clay minerals as absorbents in articles such as diapers, floor mats, utility wiping cloths, etc. is overcome by flocculating the clay into granular aggregates. The dry aggregates are dispersed into a flexible fibrous support to prepare the absorbent products. The aggregates, additionally, show enhanced water absorbing properties in many instances.
