POLYMER SOLUTION FEED MEMBER, ELECTROSTATIC SPINNING APPARATUS, AND METHOD FOR PRODUCING ELECTROSPUN NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a polymer solution feed member an electrostatic spinning apparatus, and a method for producing electrospun nonwoven fabrics, which are capable of producing nonwoven fabrics in high productivity using an electrostatic spinning apparatus. SOLUTION: The polymer solution feed member is such as to be designed to feed a polymer solution used for an electrostatically spinning process into a spinning space. The feed member consists of a hollow pipe with a hollow space, and includes through-holes penetrating from the inner circumferential wall to the outer circumferential wall of the hollow space. The electrostatic spinning apparatus is such as to include the feed member. The method for producing the electrospun nonwoven fabrics uses the electrostatic spinning apparatus.
