摘要:
To solve problems of perlite, zeolite and vermiculite which have been conventionally used as soil improving materials, and to provide a soil improving material which has excellent water retaining properties and is well-drained to retain air in a soil to thus make a soil suitable for plant growth, and a culture soil containing the soil improving material. The soil improving material of the invention includes porous ceramic particles having a moisture content of 5 vol% or greater at a pF value of not more than 2.7. The particles preferably have a water retaining ratio of 15% or greater. The particles preferably have a saturated hydraulic conductivity of 0.1 cm/s or greater.

摘要:
A method for manufacturing a fiber fabric having a hard handle is provided without using, in particular, thick yarns, manufacturing a fabric in the high density which increases loads at stages of composing and organizing the fabric, or performing resin treatment for hard finishing. The method includes performing treatment on a fabric mainly including nylon fibers with a treatment liquid containing benzyl alcohol. The treatment with the treatment liquid is performed so that the fiber fabric has a bending resistance of 100 mm or higher in at least one of a warp direction and a weft direction as measured according to a 45-degree cantilever method specified in JIS L 1096.

摘要:
A moisture-permeable waterproof fabric comprising a textile fabric and a moisture-permeable resin film containing a non-porous urethane resin layer formed on at least one side thereof, wherein the moisture-permeable waterproof fabric has a moisture permeability of 15,000 g/m 2 ·24 hr or greater according to the potassium acetate method, a moisture condensation of no more than 5 g/m 2 ·hr and a water pressure resistance of 20,000 mmH 2 O or greater, and a release-sheet attached moisture-permeable resin film comprising a release sheet and a moisture-permeable resin film formed thereon containing a non-porous urethane resin layer.
摘要:
A moisture-permeable waterproof cloth which is composed of a cloth and, formed on at least one side of the cloth, a resin coating containing a polyurethane resin which is prepared by the reaction among an isocyanate, a polyol and a chain-lenghtening agent, has a glass transition point in the range from -20 to +20 C, and contains at least 7.0 mol/kg of ethylene oxide units. It is produced either by coating at least one side of a cloth with a resin solution containing a polyurethane resin in a polar organic solvent and conducting wet coagulation in a coagulating bath to form a coating film, or by coating a release paper with a resin solution containing a polyurethane resin in a volatile organic solvent to form a resin coating and adhering the coating to at least one side of a cloth.
摘要:
A moisture-permeable waterproof fabric comprising a fiber fabric coated, on at least one side thereof, with a fluorinated polyurethane resin and a low-polymerization polyurethane resin. The fabric is produced by coating at least one side thereof with a solution of both the resins, followed by coagulation, solvent removal, drying and treatment with a water repellent.
