FIBER, FIBROUS AGGREGATE, FIBROUS ADSORBING MATERIAL AND METHOD FOR PRODUCING FIBER

摘要

PROBLEM TO BE SOLVED: To provide a fiber, fibrous aggregate and fibrous adsorbing material, capable of well adsorbing harmful substances for a human body, and a method for producing the fiber. SOLUTION: This fiber contains≥1% and≤60% double stranded DNA. The production device of the fiber is a static spinning device and an electric voltage-impressing roll 20 is installed in a dissolved liquid immersion vessel 10 housing a DNA solution. A high electric voltage-generating device 21 is joined with the dissolved liquid immersion vessel 10. At the opposing position to the electric voltage-impressing roll 20, an integral conveyer 30 is arranged so as to face its integrating surface 30A toward the electric voltage-impressing roll 20 side, and a block made from a metal 31 is arranged in a position of facing to the electric voltage-impressing roll 20 by placing the integral conveyer 30 in between. By joining the block made from the metal 31 with the high electric voltage-generating device 21, a static electric field is formed between the electric voltage-impressing roll 20 and the block made from a metal which become electrodes.
