As can be seen from the combination of example 5 and examples 10 to 12 and table 3, when the mixture of polyacrylamide and sodium polyacrylate is used as the water-absorbing resin, the water-absorbing rate of the coated tape after sterilization by ultraviolet irradiation is further decreased, and the other conditions are not changed, wherein when the weight ratio of polyacrylamide to sodium polyacrylate is 1: at 0.6, the water absorption rate of the coated belt is reduced to the minimum.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
