There are two kinds of waterproof manufacturing of textile goods, one is waterproof of air pass, the other is that of air tight and also the waterporoof manufactuing of air pass is divided into a temporary and a permanent one.
In this study I attempted to deal with three kinds of foreign water proofing agents and two kinds of domestic one by means of permanent water proof manufacturing and thus measured the effect of spray and that of spraying after washing, comparing each other.
The results of measuring and comparing the concentration of use and the effect of pray of each water proofing reveled that domestic water proofing agent, high acid amide and melamibe resin are not inferior to those of twill and flourim in the effect of spray. Also it was found that high fatty acid amide can be used for both twill and nylon, and though spray after washing is rends to reduce, it is being proved that the curing on the spot will bring about much better spraying then that of laboratory.
The concentration of use of domestic products id dealt with in higher density than foreign warter proofing agent but as raw materials are all produced in the home country and component is easy, its cost is lower then of foreign made, enobling us to use cheaper water proofing agent.
