Definitions
- Example 1 The paper made for the surface layer in Example 1 was formed into a normal non-woven fabric with a hot roll, and one surface thereof was protected with a polyethylene sheet, and then the polyether sulfone dope used in Example 1 was not protected. It was cast on the surface on the side under the same conditions and was immersed in water. This was washed with water in the same manner as in Example 1. â t5
