COMPOSITE SHEET CONTAINING POWDERY ACTIVE CARBON AND ITS PRODUCTION

Title:

COMPOSITE SHEET CONTAINING POWDERY ACTIVE CARBON AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JPH08126840

Kind Code:

A

Abstract:

PURPOSE: To produce a composite sheet maintaining high adsorbing performance, less liable to contamination, excellent in handleability and less liable to the falling of powdery active carbon by vibration as a sheet contg. uniformly dispersed powdery active carbon having satisfactory adsorbing performance.

CONSTITUTION: Heat fusible conjugated fibers are composed of a low m.p. resin and a high m.p. resin, 10-100 pts.wt. of the fibers are uniformly mixed with 0.5-15 pts.wt. synthetic pulp, and 100 pts.wt. powdery active carbon is bonded to the resultant mixture in a uniformly dispersed state by the fusion of the low m.p. resin to obtain the objective composite sheet having 20-90vol.% porosity.
