PURPOSE:To lower the cost of a trapping means by constituting the trapping means of a sandwich body which sandwiches a layer contg. a crosslinking type acidic high-polymer electrolyte having high water absorbing power with layers having liquid diffusivity. CONSTITUTION:The sandwich body 30 which sandwiches the crosslinking type acidic high-polymer electrolyte (powder) 25 with stocks 24 of filter paper, water soluble paper, news paper, non-woven fabrics, etc., having the good liquid diffusivity via polyethylene lamination layers 23 is bonded to the water absorptive layer 22 consisting of filter paper, water soluble paper, news paper, non- woven fabrics, etc., of the trapping member 21. Alkali neutralizing power and alkali and water absorbing power are provided to the sandwich body 30 by using the crosslinking type acidic high-polymer electrolyte 25. The need for a net-like nylon woven fabric for neutralizing the alkaline and absorbing the alkali and water is eliminated in this way and the cost reduction is enabled. |
