LAMINATED NONWOVEN FABRIC BAG WHICH POSSESSES EXCELLENT DRAINING PERFORMANCE AND FINE SUSPENSOID CATCHING PERFORMANCE

摘要

PURPOSE: To provide a laminated nonwoven fabric bag which possesses the excellent draining performance and fine suspensoid catching performance, and is lightweight and possesses the high mechanical strength and further possesses the excellent fitness with a sink corner part. ;CONSTITUTION: A laminated nonwoven fabric bag possesses superior draining performance and fine suspensoid catching performance, and is formed by forming a bag from the sheet material which is formed by thermally attaching a sheet of olefine group resin split cloth or a web in plain weave, twill weave or sateen weave to a nonwoven fabric 2 of a low METSUKE quantity, on the contact interface 4 of both. The fine suspensoid dust catching faculty is drastically improved in comparison with a bored polyethylene bag, etc., and draining performance can be improved. Further, the reduction of strength due to the low METSUKE quantity can be reinforced by the thermal attachment with a net made of polyolefine group resin, and the reduction of strength at the edge of the adhesion part between the net and the nonwoven fabric can be suppressed. Further, since toughness can be generated because of the attachment with the net, also the fitness with a sink corner part can be improved.;COPYRIGHT: (C)1993,JPO&Japio
