Abstract: Provided is a light-shielding sheet comprising a light-shielding material made of a white film having a light transmission of not more than 50% and a reinforcement made of a textile fabric or a nonwoven fabric. Preferred is a case where the white film is a film having therein voids formed through stretching of the film or a film having therein bubbles formed through foaming by use of a foaming agent, whereby a light-shielding sheet is provided which has a light weight, a high strength and a superior durability and which inhibits temperature increase caused by the heat resulting from sunlight absorption. The light-shielding sheet is employed suitably as a light-shielding material for agricultural use and horticultural use.

Abstract: A flap fusion sheet is formed by folding a flap continuous in the longitudinal direction in two, overlaying the side ends and fusing the inner sides of the side ends by heat to form a sleeve, at one side of a continuous backing sheet formed by laminating layers made of low melting point polyolefin on both sides of a flat yarn cloth made of high melting point polyolefin, and fusing the outer side of the sleeve in the longitudinal direction at least at other positions than the end portions in the width direction of the backing sheet.

Abstract: To present a flap fusion sheet preferably used in garage, simplified warehouse, scaffold sheet, hay cover or the like, by fusing a flap having eyelets or coupling holes to the middle of a broad backing sheet and forming a sheet to be coupled to a skeletal member.

Abstract: A flap fusion sheet is formed by fusing a flap continuous in the longitudinal direction at least at positions other than end portions in the width direction at one side of a continuous backing sheet. The backing sheet is formed by laminating layers made of a low melting point polyolefin on both sides of a flat yarn cloth made of high melting point polyolefin.

Abstract: Deformed fiber which is either a long fiber prepared by such a manner that plural parallel yarns are unified by formation of connecting parts at appropriate intervals on the longitudinal direction of yarn or particularly a short fiber prepared by cutting the above wherein the plural parallel yarns of filaments are spun from a thermoplastic resin for obtaining the deformed fiber which is effective as pile yarn or gas permeating woven fabric having a specific shape or as fiber for reinforcement of cement for improving tensile strength, bending strength, shock resistance, crack resistance, etc. of molded cement product by improving the working ability and reinforcing property as a result of compounding the short fiber prepared by cutting the deformed fiber with hydraulic substance such as concrete or mortar as a material for public works or buildings.

Abstract: The present invention provides an air filter that is excellent in anti-molding and anti-bacterial functions. The anti-mold and anti-bacteria air filter is formed from fabric knitted and woven with a warp and/or a weft made of filiform thermoplastic resin including the organic anti-molding agent and filiform thermoplastic resin including the inorganic anti-bacterial agent. It is also possible to form multi-woven fabric knitted and woven with a warp made of filiform thermoplastic resin including the organic anti-molding agent and the filiform thermoplastic resin including the inorganic anti-bacterial agent.

Abstract: In a method and an apparatus for aerobic fermentation of biodegradable refuse to produce an odorless organic fertilizer, the apparatus includes an air blower and an air sucker each comprising a plurality of horizontal cross air pipes and pendant air line members arranged in horizontally spaced relation in a fermentation vessel. The two blowers are functionally reversible and connected to each other through a heat exchanger. Each of the blowers is provided with an automatic air flow/temperature control unit for automatic operation. The method and apparatus assure ease of discharge of the product of fermentation, increased efficiency of fermentation and conservation of time, labor and energy.
