NONWOVEN FABRIC FOR SEMIPERMEABLE MEMBRANE SUPPORT |
摘要 |
<p>Provided is a nonwoven fabric for semipermeable membrane support, in which adhesiveness of a semipermeable membrane to a support is satisfactory, the thickness uniformity of the semipermeable membrane is satisfactory, and permeation-through of a coating liquid does not occur. Disclosed is a nonwoven fabric for semipermeable membrane support, in which when a region extending from the semipermeable membrane-coated side surface of the nonwoven fabric to a predetermined portion of the total basis weight in the thickness direction is designated as a coated layer region, a region extending from the non-semipermeable membrane-coated surface of the nonwoven fabric to a predetermined portion of the total basis weight in the thickness direction is designated as a non-coated layer region, and a region obtained by excluding the respective predetermined portions of the total basis weight in the thickness direction from both the semipermeable membrane-coated side surface and the non-semipermeable membrane-coated surface of the nonwoven fabric is designated as a middle layer region.</p> |
