Membranous body

Abstract

A membranous body includes a super fiber layer configured with super fiber, and resin solvent layers that are in contact with the super fiber layer and formed to interpose the super fiber layer therebetween. The super fiber layer has been subjected to at least one of a deoiling treatment and a hydrophilic treatment.

What is claimed is: 
     
         1 . A membranous body comprising:
 a super fiber layer configured with super fiber; and   resin solvent layers that are in contact with the super fiber layer and formed so as to interpose the super fiber layer between the resin solvent layers, wherein the super fiber layer has been subjected to at least one of a deoiling treatment and a hydrophilic treatment.   
     
     
         2 . The membranous body according to  claim 1 , wherein resin solvent constituting the resin solvent layers is coated on the super fiber layer. 
     
     
         3 . The membranous body according to  claim 2 , wherein the resin solvent includes a super engineering plastic. 
     
     
         4 . The membranous body according to  claim 1 , wherein:
 the super fiber layer has at least two threads out of a first thread, a second thread, and a third thread;   the first thread is a thread that extends in a first direction and is formed to include the super fiber;   the second thread is a thread that extends in a second direction different from the first direction and is formed to include the super fiber;   the third thread is a thread that extends in a third direction different from the first direction and the second direction and is formed to include the super fiber; and   the at least two threads are intertwined with each other such that fluctuation of relative positions between the at least two threads is restrained, or the at least two threads are bound by at least one of a machine sewing thread and a melt thread such that the fluctuation of the relative positions between the at least two threads is restrained.   
     
     
         5 . The membranous body according to 1, wherein:
 the super fiber layer includes a plurality of threads that are formed to include the super fiber and extend in one direction; and   two adjacent threads out of the plurality of threads are intertwined with each other such that fluctuation of relative positions between the two adjacent threads is restrained.   
     
     
         6 . The membranous body according to  claim 1 , wherein the membranous body has a tensile strength of 51 to 64 N/mm and a mass of 45 to 55 g/m 2 .
