テンを内張りすることが多く行われている。2. Description of the Related Art In recent years, house farming using an agricultural house and horticulture by greenhouse cultivation have become widespread. In these horticultural facilities, the heat insulation inside the house, which is generally formed by stretching translucent glass or film,
For the purpose of performing ventilation, light quantity control, day length control, etc.
It is often practiced to line a curtain composed of various non-woven fabrics, cloths such as Chinese sardine cloth, nets, plastic films, or laminates thereof.

取り可能に設置することが行われている。Curtain materials used for these lining curtains include polyvinyl chloride films (commonly known as "agricultural plastics"), polyolefin films, or films such as aluminum foil laminated on the film surface or aluminum-vapor-deposited reflective films. Cloths, non-woven fabrics, cloth such as ginseng, or nets are used. Then, these curtain materials are stretched around the inner wall surface or the ceiling portion of the house so that they can be opened and closed as necessary or can be wound up.

どが挙げられる。The performance required for such a curtain material is that it is thin and lightweight, has excellent heat retention, is transparent, and has mechanical strength (tensile, tearing, bending resistance, etc.). Large size, high dimensional stability (does not expand and contract), good opening and closing properties (not sticky, soft and easy to fold and wind), weatherproof, and has good flowability (There is no dew condensation and water droplets are hard to attach), and it is easy to process.

る。Among the above curtain materials, the polyvinyl chloride film (agricultural vinyl) is rich in flexibility, has good translucency, and relatively satisfies the above-mentioned various performances such as heat retention and weather resistance. It is widely used as an agricultural coating material because of its good workability. However, since polyvinyl chloride film (agricultural vinyl) has weak mechanical strength and has the property of being easily stretched, when it is used as a curtain for a house lining,
Rainwater that has entered through the skylights of the house, etc., or water droplets that have condensed on the inner surface of the covering material on the outside of the house will drop onto the curtain, and the film material of the curtain will stretch due to the weight of the water, and water will form on the bag-like film surface. There is a problem that a accumulated state, that is, a water accumulation phenomenon occurs. In addition, there are drawbacks such that the deformation progresses and breakage easily occurs during repeated use.

Ｆが提案されている。When the water puddle phenomenon occurs, every time the film is shaken by the wind, the accumulated water overflows and damages crops in the house, and the weight of the water damages the curtain, which is a fatal drawback. Become. Therefore, as a means for eliminating this water accumulation phenomenon, Japanese Utility Model Publication No. 5-10598 discloses an agricultural use for a liner curtain provided with one or more through holes b in a synthetic resin film a as shown in FIG. A perforated film F has been proposed.

題点を有している。However, since the perforated film F for agriculture is provided with the through holes b, even if it is possible to prevent the occurrence of a water pool phenomenon when it is used as a lining curtain, the water leaked through the through holes b is applied to the crop. However, there are problems such as damage due to heat damage and deterioration of heat retention and damage due to reduced mechanical strength.

い。If the thickness of the transparent polyethylene terephthalate film exceeds 100 μm, the flexibility and translucency are reduced, and if it is less than 1 μm, the mechanical strength as a curtain material is reduced, which is unsuitable. If the thickness of the soft polyvinyl chloride resin film exceeds 0.2 mm, the weight per unit area increases, which is unsuitable as a curtain.
If it is thinner than mm, the weather resistance is deteriorated, which is not preferable.
