Abstract

Provided is a cyclic olefin-derived resin microfiber and a cyclic olefin-derived resin non-woven fabric. A polymer solution containing a volatile solvent and a cyclic olefin-derived resin is subjected to electrostatic spinning. The volatile solvent to be used preferably contains at least one solvent selected from the group consisting of chloroform, toluene, xylene, cyclohexane and decalin. In addition, by using a cyclic olefin-derived resin with a glass transition point of at least 160° C., high heat-resistance can be imparted to a cyclic olefin-derived resin fiber.

Claims

exact text as granted — not AI-modified
1 . A cyclic olefin-derived resin fiber having an average fiber diameter of from 0.01 μm to 10 μm, wherein the fiber is formed by electrostatic spinning of a polymer solution comprising a volatile solvent and a cyclic olefin-derived resin. 
     
     
         2 . The cyclic olefin-derived resin fiber according to  claim 1 , wherein the fiber has an average fiber diameter of from 0.1 μm to 0.5 μm. 
     
     
         3 . The cyclic olefin-derived resin fiber according to  claim 1 , wherein the volatile solvent contains at least one solvent selected from the group consisting of chloroform, toluene, xylene, cyclohexane and decalin. 
     
     
         4 . The cyclic olefin-derived resin fiber according to  claim 1 , wherein the cyclic olefin-derived resin has a glass transition point of 160° C. or higher. 
     
     
         5 . A cyclic olefin-derived resin non-woven fabric formed from the cyclic olefin-derived resin fiber according to  claim 1 . 
     
     
         6 . The cyclic olefin-derived resin fiber according to  claim 2 , wherein the volatile solvent contains at least one solvent selected from the group consisting of chloroform, toluene, xylene, cyclohexane and decalin. 
     
     
         7 . The cyclic olefin-derived resin fiber according to  claim 2 , wherein the cyclic olefin-derived resin has a glass transition point of 160° C. or higher. 
     
     
         8 . A cyclic olefin-derived resin non-woven fabric formed from the cyclic olefin-derived resin fiber according to  claim 2 .
