Title:
AIR FILTERING MODIFIED NONWOVEN FABRIC, AIR FILTERING DEVICE CONSISTING OF THE SAME, AND MODIFIED NONWOVEN FABRIC MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2017014643
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a modified nonwoven fabric, which has amphipathic surfaces and is excellent in fine particle collecting capacity, processability, stability and air permeability, and an excellent air filtering device.SOLUTION: A nonwoven fabric is modified by following processes: a process based on a counter collision handling method to make a pair of nozzles 108 inject a pulp dispersion liquid at high pressure and pulverize the injected pulp dispersion liquid by making the jet flows collide against each other; and a process to obtain a processing liquid containing cellulose nanofibers by the counter collision handling method and coat the nonwoven fabric with cellulose nanofibers. A carrying sanitary mask and an air cleaning filter are manufactured by using the modified nonwoven fabric as a constituent material.SELECTED DRAWING: Figure 1
