A piezoelectric stack includes a porous resin sheet, and a surface coating layer disposed on an exterior surface of the porous resin sheet, the exterior surface including at least one of a front surface and a back surface of the porous resin sheet, the surface coating layer having a volume resistivity of not less than 1×10.sup.13 Ω.Math.cm, the porous resin sheet and the surface coating layer having different elastic moduli.

An abrasion resistant finish for a fungal material, the finishing comprising an optimum quantity biodegradable polylactic acid plastic (PLA) dispersed in water to produce a PLA mixture. When the PLA mixture is applied to the fungal material, water carries the PLA deeply into the matrix of the fungal hyphae to a depth at least 2 N/10 mm or 1% of the thickness of the fungal material, whichever is greater. The finish fortifies the hyphal structure as the water evaporates and creates a PLA coating on the fungal material with improved abrasion resistance and water resistance.

A synthetic leather is lightweight and highly durable to abrasion, and a foamed resin layer can give the synthetic leather. The foamed resin layer includes a poly(vinyl chloride) resin and a thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer preferably has a Shore A hardness of 50 to 80. The foamed resin layer preferably has an apparent density of 0.3 to 0.7 g/cm.sup.3. The foamed resin layer preferably has an average cell size of 50 to 250 m.

An air bag coated with a cured organopolysiloxane composition, characterized in that the air bag is top coated with an antifriction coating comprising at least one solid lubricant dispersed in an organic polymer binder.

It is intended to provide a novel artificial sueded leather having flame retardance, which is excellent inflame retardance, light resistance and abrasion resistance, suffers from no water spot and is free from any halogenated chemical (i.e., one having been treated with a so-called non-halogenated flame retardant), and a method of producing the same. The above artificial sueded leather comprises a thermoplastic synthetic fiber cloth made of a woven fabric, a knitted web or a nonwoven fabric, which has a raised-fiber or napped-fiber surface and has been impregnated with a polyurethane resin, and a flame retardant which contains at least a phosphate compound A having a solubility in water of 1% or less, a vinyl group-containing resin C capable of forming a carbonization skeleton in burning and a water-insoluble thickener D and is imparted to one face of the thermoplastic synthetic fiber cloth. A method of producing the artificial sueded leather as described above comprises imparting an flame retardant, which contains at least a phosphate compound A having a solubility in water of 1% or less, a vinyl group-containing resin C capable of forming a carbonization skeleton in burning and a water-insoluble thickener D, to one face of a thermoplastic synthetic fiber cloth made of a woven fabric, a knitted web or a nonwoven fabric which has a raised-fiber or napped-fiber surface and has been impregnated with a polyurethane resin.

The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials according to the invention are suitable for manufacturing base interlinings which may be used for manufacturing base interlinings for sarking, roofing and sealing membranes, particularly for manufacturing coated sarking, roofing and sealing membranes.

An airbag textile containing a woven textile having an inner side and an outer side, a primer layer on the outer side of the textile and a gas barrier layer on the primer layer. The primer layer contains a first thermoplastic polymer and has a surface roughness and a plurality of holes extending at least partially through the thickness of the primer layer. The gas barrier layer contains a second thermoplastic polymer and at least partially fills in the surface roughness and holes of the primer layer.
