Abstract
An environment-friendly active cloth includes a fiber layer and a active cloth layer, and its manufacturing method. The active-cloth has a rough, properly soft and irregular surface, made of a first catalyst, a second catalyst, paste plant starch, liquid non-grain PVA, and a foam agent of proper weight mixed together. The active cloth layer has many percolating air holes, forming a single unit.

An environment-friendly active cloth comprising:
- a fiber layer;
- and at least one active cloth attached to said fiber layer, said at least one active cloth layer having a rough, soft and irregular surface and made of a first catalyst, a second catalyst, paste plant starch, ad liquid non-grain polyvinyl alcohol (PVA), so as to form a single unit containing microporous air holes in said active cloth layer.
A method for manufacturing an environment-friendly active cloth comprising the steps of:
- mixing materials consisting of paste plant starch of 28%-47% wt., liquid non-grain PVA of 47%-65% wt., a first catalyst of 3.6%-10.0% wt., a second catalyst of 4.5%-10.0% wt., a foam agent of 0.015%-0.06% wt. of the aggregate weight, and stirring all of said materials into a solution;
- coating said mixed solution evenly on a fiber layer to form an active cloth layer on said fiber layer;
- reacting said active cloth layer with said fiber layer by foaming;
- lowering the temperature and cooling said active cloth layer with said fiber layer, washing and compressing said active cloth layer with said fiber layer;
- and drying said active cloth layer with said fiber layer to obtain said environment-friendly active cloth.
