農業用被覆材として不織布シートは非常に優れた
ものである。 BACKGROUND ART Conventionally, komo, rakawa, cheesecloth, etc. have been used for the purpose of keeping crops warm and cold. In recent years, nonwoven fabric sheets have been used for these purposes. Although nonwoven fabric sheets are air permeable, they have good properties as a heat insulating material in the winter, and they also have good properties as a cold insulating material in the summer because they have excellent light blocking properties. Therefore, nonwoven fabric sheets are very suitable as general-purpose agricultural covering materials throughout the winter and summer seasons.

という性質がある。この性質は、農業用被覆材と
して使用した場合、採光、換気等の目的で開閉す
る際、農業用被覆材が破れてしまうという欠点と
なつて発現する。 However, since nonwoven fabric sheets are made by accumulating constituent fibers such as staple fibers and endless filaments and forming them into sheets, the strength of the edges of the sheet is lower than that of cheesecloth, woven fabrics, etc. obtained using spun yarn. , and therefore has a property of low tear strength. This property manifests itself as a drawback in that when used as an agricultural covering material, the agricultural covering material is torn when opened and closed for the purpose of lighting, ventilation, etc.
そこで本考案は、不織布シートの縁部に特定の
樹脂層を設けることにより、縁部の引裂強度を高
くした農業用被覆材とすることにより、開閉時に
前記した欠点を生じることのないようにしたもの
である。 Therefore, the present invention has created an agricultural covering material that has increased tear strength at the edges by providing a specific resin layer on the edges of the nonwoven fabric sheet, thereby eliminating the above-mentioned drawbacks when opening and closing. It is something.

られる。 The present invention will be explained in more detail with reference to the drawings. 1st
The figure is a cross-sectional view of the agricultural covering material 3 according to the present invention. For the belt-shaped nonwoven fabric sheet 1, a known nonwoven fabric such as a dry nonwoven fabric, a wet nonwoven fabric, or a spunbond nonwoven fabric is used.

等の影響を受けない繊維を用いるのが好ましい。 The thermoplastic resin layer 2 is installed, for example, by heating and melting a thermoplastic resin, extruding it from a slit opening with an extruder, and supplying it to the longitudinal edge of the strip-shaped nonwoven fabric sheet 1. Therefore, when using this method, it is preferable to use fibers that are not affected by shrinkage, deterioration, etc. near the melting temperature of the thermoplastic resin as the fibers constituting the strip-shaped nonwoven fabric sheet 1.

It is used as shown in the figure, and when opened or closed for lighting, ventilation, etc., it is rolled up from one edge and covered. Therefore, the thermoplastic resin layer 2 for reinforcing the edge may be provided on one longitudinal edge that is handled when opening and closing. Of course, the thermoplastic resin layer 2 may be provided on both longitudinal edges, or the thermoplastic resin layer 2 may be provided on the edge in the width direction.
