MANUFACTURING METHOD OF NONWOVEN FABRIC FOR A FUNCTIONAL AIRFILTER COMPRISING ANTIBACTERIAL COPPER FIBERS, AND THE NONWOVEN FABRIC FOR A FUNCTIONAL AIRFILTER COMPRISING ANTIBACTERIAL COPPER FIBERS MADE BY THE SAME

摘要

The present invention is a polypropylene short fiber, polyethylene-polyethylene terephthalate composite short fiber, and acryl-copper composite short fiber opening (Opening) and mixing (Mixing) at a predetermined mixing ratio (Mixing) and mixing step (S1) and; Carding step (S2) of carding (carding) the fiber opening and the mixed short fibers and; a lower web forming step (S3) of forming a lower web 5 using the carded short fibers; An activated carbon particle application step (S4) of applying the activated carbon particles (4) for applying the activated carbon particles (4) to the upper surface of the lower surface of the web (5); An upper web forming step (S5) of forming an upper web (3) suitable for the size of the lower web (5) to which the activated carbon particles (4) are applied (S5); an activated carbon nonwoven fabric forming step (S6) of calendering the lower web 5 and the upper web 3 coated with the activated carbon particles 4 to form an activated carbon nonwoven fabric; A melt blown nonwoven fabric preparation step (S7) of preparing a melt blown nonwoven fabric (1) suitable for the size of the activated carbon nonwoven fabric; a thermal bonding step (S8) of aligning and thermally bonding the activated carbon nonwoven fabric and the melt blown nonwoven fabric (1) with an adhesive to form a nonwoven fabric for an air filter; an immersion step (S9) of immersing the nonwoven fabric for air filter in an aqueous solution of phytoncide; A method for manufacturing a nonwoven fabric for a functional air filter containing antibacterial copper fibers, characterized in that it includes a drying step (S10) of taking out the immersed nonwoven fabric for air filter from an aqueous solution of phytoncide and drying it, and a functional air filter containing antibacterial copper fibers It relates to a nonwoven fabric for a functional air filter comprising an antibacterial copper fiber manufactured by a manufacturing method for a nonwoven fabric for use.
