Abstract

The invention involved a novel sorbent structure and the absorption products containing this structure. In particular, this fabricated absorbent structure consists of a large, tall, low-density closed layer, a denser shipping layer, a very high-density retention layer. And a protective layer that water cannot seep through With the sealing layer and the protective layer being sealed around the circle and good way, every The tiers should be joined together to form a joint structure.
