Abstract
Description
本発明は、農業または施設園芸用途に使用される温度調整用資材に関し、詳しくは展張性および巻き上げ性に優れる温度調整用資材に関する。 The present invention relates to a temperature control material used for agriculture or facility horticulture, and more particularly to a temperature control material excellent in stretchability and roll-up property.
従来、農業用・施設園芸用ハウス内で各種作物を栽培するハウス栽培においては、夏場は日中の強い日差しによるハウス内温度の過上昇防止、冬場はハウス内温度の維持のために、温度調整用資材を適宜ハウスの天部に拡げ、ハウス内の環境を良好にして、作物の成長を図っている。 Conventionally, in house cultivation where various crops are cultivated in agricultural / facility horticultural houses, temperature adjustment is performed in summer to prevent overheating of the house due to strong sunlight during the day, and to maintain the house temperature in winter. The materials are expanded to the top of the house as appropriate to improve the environment in the house and to grow the crop.
かかる温度調整用資材としては、近年種々の素材について研究がすすめられており、例えばポリエチレン、ポリプロピレン、ポリエステル等の合成樹脂製素材を用いて形成された織布、不織布が開示されている（例えば特許文献１）。さらに保温性を向上させるために、マット状のものも知られている。 In recent years, various materials have been studied as such temperature control materials, and for example, woven fabrics and non-woven fabrics formed using synthetic resin materials such as polyethylene, polypropylene, and polyester are disclosed (for example, patents). Reference 1). Further, a mat-like one is also known in order to improve heat retention.
ハウスに温度調整用資材をかぶせるときの多くはロール状に巻き付けた温度調整用資材をハウスの天頂部に取り付け、手動またはモーターを使用して、ロールをハウスの屋根に巻き戻し、温度調整用部材を広げていくという作業を行う。マット状の温度調整用資材の場合、温度調整用資材をロールの状態からシートの状態に広げるときや、温度調整用資材をロール状に巻き上げるとき、保温を前提としたマット状の資材の厚みから質量が増え、その結果巻き取りや展張に大きなトルクが必要となる。そのためモーターの出力アップまたはモーターの追加が必要になったり、ハウスの構造を強化したりする必要があった。またマット状のものは保温性能は向上するものの、天頂部の巻き径が従来用いられているフィルムに比べて大きくなり、その部分が日陰となり、作物の収穫量に影響する問題があった。同じように、折り畳んだ形態と平らな形態とを行き来させるカーテン式の装置に設置する場合においても、収納時に収束性が不十分で、日陰部分が大きくなる問題があった。 In many cases, the temperature adjustment material is put on the house in a roll shape, and the temperature adjustment material is attached to the top of the house, and the roll is rewound onto the roof of the house manually or using a motor. Work to spread the. In the case of mat-like temperature adjustment materials, when expanding the temperature adjustment material from the roll state to the sheet state, or when winding the temperature adjustment material into a roll shape, from the thickness of the mat-like material assuming heat retention The mass increases, and as a result, a large torque is required for winding and spreading. Therefore, it was necessary to increase the output of the motor or add a motor, or to strengthen the structure of the house. In addition, the mat-shaped one has improved heat retention performance, but the winding diameter of the zenith portion is larger than that of a conventionally used film, and this portion is shaded, which has a problem of affecting the crop yield. Similarly, in the case of installing in a curtain type device that moves back and forth between a folded form and a flat form, there is a problem that the convergence is insufficient at the time of storage and the shaded part becomes large.
本発明では、軽量で、ロールへの巻き取りやカーテン装置で展張した場合の収束性が良く、保温性に優れたマット状の農業用または施設園芸用温度資材を提供することを課題とする。 An object of the present invention is to provide a mat-like temperature material for agriculture or facility horticulture that is lightweight, has good convergence when wound on a roll or stretched by a curtain device, and has excellent heat retention.
上記課題を解決するために、本発明は以下の構成からなる。

(6) The material for temperature adjustment according to any one of the above, wherein a mat having a cushion layer sandwiched between two side fabrics is integrated by sewing.
本発明によれば軽量で、ロールへの巻き取り性やカーテン開閉装置をしようしたときの収束性に優れたマット状の農業用または園芸用温度資材が得られる。 According to the present invention, it is possible to obtain a mat-like temperature material for agriculture or horticulture that is lightweight and excellent in winding property on a roll and convergence when a curtain opening / closing device is used.
以下本発明を実施するための形態について説明する。 Hereinafter, modes for carrying out the present invention will be described.
本発明の温度調整用資材は、布帛からなる側地でクッション層を包み込んだマットからなる。 The temperature adjusting material of the present invention is made of a mat in which a cushion layer is wrapped with a fabric side.
側地を構成する布帛としては、織物、編物および不織布いずれでも利用可能であるが、変形防止性から織物が好ましく利用できる。天然繊維、化学繊維、合成繊維いずれも利用できるが、合成繊維が好ましい。合成繊維としては、ポリエチレン、ポリプロピレンなどのポリオレフィン、ナイロン６、ナイロン６６などのポリアミド、ポリエチレンテレフタレート、ポリブチレンテレフタレートなどのポリエステルが利用できる。繊維の吸水性が高くなると、湿度が高いとき、資材の質量が大きくなることから、前記のうちポリオレフィン、ポリエステルが好ましい。なかでもポリエステルが好ましい。布帛を構成する繊維の単糸繊度としては、０．４から５．８dtexの範囲が好ましい。また総繊度は２３３dtex以下、より好ましくは５５〜１６７dtexの範囲が好ましい。総繊度が高すぎると、得られる資材の収束性が低くなる傾向がある。また総繊度は低いほうがいいが、低すぎると、微細な突起物に本発明の温度調整用資材が接触すると傷がつきやすい。加えて、側地の目付は５０〜１００ｇ／ｍ２であることが好ましい。高すぎると得られる資材の収束性が低くなり、一方小さいと突起物により傷がつきやすくなる傾向がある。 As the fabric constituting the side fabric, any of a woven fabric, a knitted fabric and a non-woven fabric can be used, but a woven fabric is preferably used from the viewpoint of deformation prevention. Natural fibers, chemical fibers, and synthetic fibers can be used, but synthetic fibers are preferred. As synthetic fibers, polyolefins such as polyethylene and polypropylene, polyamides such as nylon 6 and nylon 66, and polyesters such as polyethylene terephthalate and polybutylene terephthalate can be used. Of these, polyolefins and polyesters are preferred because when the fiber absorbs water, the mass of the material increases when the humidity is high. Of these, polyester is preferable. The single yarn fineness of the fibers constituting the fabric is preferably in the range of 0.4 to 5.8 dtex. The total fineness is preferably 233 dtex or less, more preferably in the range of 55 to 167 dtex. If the total fineness is too high, the convergence of the resulting material tends to be low. The total fineness should be low, but if it is too low, the temperature adjustment material of the present invention will be easily damaged when it comes into contact with fine protrusions. In addition, the basis weight of the side ground is preferably 50 to 100 g / m 2 . If it is too high, the convergence of the resulting material will be low, while if it is small, it tends to be easily damaged by protrusions.
側地を構成する布帛はＪＩＳ−Ｌ１０９６Ａ法（４５°カンチレバー法）によって得られる剛軟度が７０ｍｍ以下であることが好ましい。さらには５５ｍｍ以下が好ましい。剛軟度が小さいことにより、本発明の温度調査資材の収束性が良好となる。 The fabric constituting the side fabric preferably has a bending resistance of 70 mm or less obtained by the JIS-L1096A method (45 ° cantilever method). Furthermore, 55 mm or less is preferable. Since the bending resistance is small, the convergence of the temperature survey material of the present invention is improved.
側地を構成する布帛は、着色していてもよい。金属箔が積層していてもよい。紫外線吸収剤、耐候材を含んでいてもよい。 The fabric constituting the side fabric may be colored. Metal foil may be laminated. An ultraviolet absorber and a weathering material may be included.
クッション層としては、綿状の資材が好ましい、クッション層の存在は、収納性および保温性に影響を与える資材である。クッション層の目付としては４０から１００ｇ／ｍ２の範囲が好ましい。目付が小さすぎると保温効果に乏しくなる。クッション層が４０ｇ／ｍ２以下では熱貫流率の測定結果より、断熱性能の低下が急激に大きくなる（表２）。その一方で、クッション層の目付は大きすぎると収納性が悪化する。より望ましくは、５０から８０ｇ／ｍ２の間であり、ハウス内での吸湿による劣化や嵩高の減少を防ぐため、天然繊維よりもポリエステル繊維等の合成繊維が好ましい。 As the cushion layer, a cotton-like material is preferable. The presence of the cushion layer is a material that affects the storage property and the heat retaining property. Range of 100 g / m 2 are preferred from 40 as the basis weight of the cushion layer. If the basis weight is too small, the heat retention effect is poor. When the cushion layer is 40 g / m 2 or less, the decrease in the heat insulation performance is rapidly increased from the measurement result of the thermal permeability (Table 2). On the other hand, if the basis weight of the cushion layer is too large, the storage property is deteriorated. More desirably, it is between 50 and 80 g / m 2 , and synthetic fibers such as polyester fibers are preferable to natural fibers in order to prevent deterioration due to moisture absorption and reduction in bulk in the house.
側地とクッション層からなるマットの一体化にあたっては、一方向、特に屋根に資材を設置したときに屋根の勾配と垂直になる方向に、直線的な縫製を、間隔をおいて複数行うことが望ましい。一方向であることで、設置現場でサイズ調整のために裁断する場合、裁断方向の目安とすることができる。また屋根の勾配と垂直になる方向にあることで、折り畳んだときの折り線となることができる。縫製の間隔は、５から２０ｃｍまでの範囲が望ましい。５ｃｍ以下であると、クッション層が薄くなり、保温効果が低下する。２０ｃｍ以上であった場合は、収納時に相対する布帛にずれが生じ易くなり、しわの発生や巻き取り斑が生じる原因となる。 When integrating mats composed of side grounds and cushion layers, it is possible to perform multiple linear sewings at intervals in one direction, especially in the direction perpendicular to the roof slope when materials are installed on the roof. desirable. By being unidirectional, when cutting for size adjustment at the installation site, it can be used as a guide for the cutting direction. Moreover, it can become a fold line when it folds by being in the direction perpendicular to the slope of the roof. The sewing interval is preferably in the range of 5 to 20 cm. When it is 5 cm or less, the cushion layer becomes thin and the heat retaining effect is lowered. When it is 20 cm or more, the cloths facing each other tend to be displaced during storage, causing wrinkles and winding spots.
本発明では、第１の側地、クッション層および第２の側地からなる試料のＪＩＳ−Ｌ１０９６Ａ法（４５°カンチレバー法）によって得られる剛軟度が１００ｍｍ以下であること好ましい。さらに好ましくは６０〜９０ｍｍの範囲である。この剛軟度が小さいことにより本発明の温度調整用資材がロールとして巻き取りやすくなる。剛軟度が大きすぎると、従来の設備での展張が不可能であったり、収納時に嵩や巻き径が大きく、日陰が増えたりすることで、作物の収穫量に影響を与える。剛軟度が小さすぎると、施工時や実際の展張時に破れる傾向がある。 In this invention, it is preferable that the bending resistance obtained by the JIS-L1096A method (45 degree cantilever method) of the sample which consists of a 1st side place, a cushion layer, and a 2nd side place is 100 mm or less. More preferably, it is the range of 60-90 mm. Due to the small bending resistance, the temperature adjusting material of the present invention can be easily wound up as a roll. If the bending resistance is too large, it will not be possible to expand with conventional equipment, or the bulk and winding diameter will be large and the shade will increase during storage, affecting the crop yield. If the bending resistance is too small, there is a tendency to be broken during construction or actual extension.
