LAMINATED ARTICLE OF FIBER-LIKE ACTIVATED CARBON KNITTED FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a laminated article obtained by superposing a front cloth and a rear cloth on front and rear surfaces of a fiber-like activated carbon knitted fabric having a large adsorption performance of organic solvent gas per unit area, high air permeability and strong tearing strength and quilting the front and rear clothes.;SOLUTION: The fiber-like activated carbon knitted fabric is obtained by thread-like forming a fiber-like polymer precursor, knitting the precursors, then carbonizing and activating the knitted fabric. In the knitted fabric, its toluene adsorbing performance is 25 g/m² or more, its air permeability is 250 cm³/cm².s or more, and its tearing strength is 2.5 N or more. The front cloth and the rear cloth are superposed on the front and rear surfaces of the knitted fabric, and quilted the laminated article. Further, its absolute dry mass is 80 to 250 g/m². Its specific surface area according to a BET method is 1,000 to 3,000 m²/g. The laminated article of the fiber-like activated carbon knitted fabric is obtained by rib-stitching or interlock stitching the knitted fabric.;COPYRIGHT: (C)2003,JPO
