摘要:
An absorbent article having, as a back sheet, a porous sheet obtainable by preparing, by melt blending, a melt blended solution comprising 30 to 90 parts by weight of a crystalline polyolefin and 10 to 70 parts by weight of a compound with which the crystalline polyolefin is miscible and in which the crystalline polyolefin will dissolve at or above the melting point of the crystalline polyolefin but which will phase separate below the melting point of the crystalline polyolefin, molding the blended solution into a sheet, and stretching the sheet in at least one direction. The crystalline polyolefin is a polypropylene having a weight average molecular weight (Mw) to number average molecular weight (Mn) ratio (Mw/Mn) of no more than 6.0.
摘要:
A molded article (10) made predominantly of pulp and comprising a bottom portion (13) and a body portion (12), wherein the angle θ between the outer surface of a side wall of the body portion (12) and the ground contact plane (B) of the bottom portion (13) is 85° or greater, and the height of the body portion (12) is 50 mm or more.
摘要:
Pulp deposited bodies (7 and 8) are formed on the surfaces (2a and 3a) of a set of splits (2 and 3) of a papermaking mold, each split having a plurality of interconnecting holes connecting the outside to the inside thereof, and the splits (2 and 3) are mated to join the pulp deposited bodies (7 and 8).

摘要:
A pulp molded container comprising a pulp molded article (2) having on the inner surface and/or the outer surface thereof a resin layer (3) with a thickness of 5 to 300 μm formed by applying a coating, wherein the thickness ratio of the resin layer (3) to the molded article (2) (former/latter) is 1/2 to 1/100, and the surface roughness profile of the outer or inner surface of the pulp molded article is such that a centerline average roughness (Ra) is 0.5 to 20 μm.
摘要:
A molded body formed with pulp mold having projected lines corresponding to a slit-shaped vent package part, capable of being provided by paper-making/dewatering, using a paper making mold, a slurry having fibers dispersed in a liquid so as to obtain a three-dimensional fiber wetted laminated body, moving the laminated body to a dry mold having an inner surface with the slit-shaped vent package, and pressing and drying that laminated body.
摘要:
A shape memory rubber molded article (1) obtained from a mixture containing a rubber and a crystalline non-polymeric compound. The rubber in the molded article is crosslinked. A deformed state of the shape memory rubber molded article (1) is fixed by crystallizing the non-polymeric compound, and the fixed deformed state is released by melting the non-polymeric compound. The non-polymeric compound is preferably a wax. The shape memory rubber molded article (1) preferably contains a crosslinking agent. In the molded article (1), the rubber and the non-polymeric compound are preferably in finely divided separate phases.
摘要:
A process of producing a wax composition mainly comprising a wax, including the step of mixing the wax and a component to be mixed with the wax by applying an external force at a temperature lower than the melting completion temperature of the wax.
摘要:
A biodegradable wax composition containing a wax as a main component and also containing a biodegradable polymer and a filler and having a moisture permeability of 3 g·mm/m2·24 hr or less at 40° C. and 90% RH. The wax is preferably present in an amount of 65 to 95% by weight. The biodegradable polymer preferably has a weight average molecular weight of 200,000 or higher. The polymer is preferably polyisoprene or natural rubber and is preferably present in an amount of 5 to 35% by weight.
摘要:
A heat-insulating container having a first fiber layer (111) with a prescribed density and a second fiber layer (112) which is formed inside the first fiber layer (111) and has a lower density than the first fiber layer (111). The first fiber layer (111) is 0.2 to 1 mm thick, and the second fiber layer (112) is 0.4 to 3 mm thick, with the total thickness of the first fiber layer (111) and the second fiber layer (112) being 0.6 to 4 mm.
