Filed: 1991-05-23
Abstract: PURPOSE:To obtain good pleating property and to decrease deformation of pleats due to long-term use or heat by heat fusion bonding a net comprising heat-fusible monofilaments and metal fine wires with synthetic fiber nonwoven fabric into one body. CONSTITUTION:A net comprising heat-fusible monofilament and metal fine wire is heat fusion bonded with synthetic fiber nonwoven fabric into one body. Especially, the metal fine wires are made to entangle with the heat-fusible monofilament in a manner that the necessary amt. of metal wires are disposed along the longitudinal direction of the synthetic fiber nonwoven fabric. In the process of pleating, good flatness of pleats is obtd. by the heat-fusible monofilament, while pleating property to maintain the pleated state is obtd. by the metal wires. Thus, both of flatness and pleat-holding property can be obtd. and the obtd. filter material has good secondary working property having excellent pleating property and showing little deformation of pleats even for long-term use or heat. Further, when a synthetic fiber nonwoven fabric having permanent charge as electret is bonded with a monofilament containing metal wires, durability of removing efficiency as a filter medium can be improved.

IPC: C09K8/20
Filed: 1990-06-07
Abstract: PURPOSE: To form a swollen and rigid polymer and prevent water from transferring to peripheral soils from a ditch by charging slurry composed of modified polysaccharides into muddy water in the constriction ditch digged around a building. CONSTITUTION: As a slurry for forming a diaphragm wall, modified polysaccharides, where a polysaccharides 1% solid solution has at least 1000 mPAS in viscosity at 25 deg.C and an in-water polysaccharides mixture generates at least 10 wt.% of gelatin particles, are charged into muddy water filled for preventing break of a side surface of a ditch digged around a building.
