れている。BACKGROUND ART Nonwoven fabric sheets for agriculture are used as a material having heat insulation and air permeability for various types of agriculture such as curtains in houses or tunnel hangings and outdoor cultivations, tunnel cultivations, direct cultivations such as greenhouse cultivations. Widely used as a covering material.
考案が解決しようとする課題 農業用不織布は、同じく農業用被覆材として広く用い
られるフィルムと比べ、通気性があり、日中での高温障
害を起こしにくい利点がある反面、保温性に劣る難点が
ある。Problems to be Solved by the Invention Nonwoven fabrics for agriculture have the advantages of being more breathable and less likely to cause high temperature damage during the day, as compared with films that are also widely used as covering materials for agriculture, but have the drawback of being poor in heat retention. is there.
本考案の目的は、通気性を損なわずに保温性に優れた
農業用不織布シートを提供することを目的とする。An object of the present invention is to provide an agricultural nonwoven fabric sheet having excellent heat retention without impairing air permeability.
課題の解決手段 本考案によれば、そのため目付が15〜30g/m2の合成樹

ートが提供される。According to the present invention, therefore, a plurality of synthetic resin non-woven fabrics having a basis weight of 15 to 30 g / m 2 are superposed on each other, and they are heat-melted by an ultrasonic welder or heater composed of a heat generation part and a contact part. Provided is an agricultural nonwoven fabric sheet which is partially joined and integrated by using a garment.
接合は点接合でもよいし、曲線または直線の線接合で
もよいが、接合部の総面積は不織布シートの表面積の５
％以下とするのが望ましい。The joining may be point joining, or curved or straight line joining, but the total area of the joined portion is 5 times the surface area of the nonwoven fabric sheet.
% Or less is desirable.
作用 超音波ウェルダーやヒータ等で不織布層を部分的に熱
融着する場合、高分子繊維は熱によって収縮する性質が
あるから、シール部を上下より挟む熱融着具の熱発生部
側の不織布が収縮して、上下の布間にずれを生ずること
により、非融着部が少し膨れて空気層を形成するように
なり、これにより保温性を増す。Action When partially heat-bonding the non-woven fabric layer with an ultrasonic welder or heater, the polymer fibers have the property of shrinking due to heat, so the non-woven fabric on the heat-generating part side of the heat-sealing tool that sandwiches the seal part from above and below. Contracts to cause a gap between the upper and lower cloths, so that the non-fused portion slightly swells to form an air layer, thereby increasing heat retention.
不織布シートは目付やフィラメントの線径、絡合手段
等製造条件を変えることによって通気性を広い範囲で変
えることができる。The breathability of the nonwoven fabric sheet can be varied over a wide range by changing the manufacturing conditions such as the basis weight, filament wire diameter, and entanglement means.
なお不織布の目付は、30g/m2を越えると、通気性が損
われ、高温障害防止のため換気が必要となって好ましく
ない。If the basis weight of the nonwoven fabric exceeds 30 g / m 2 , the air permeability is impaired and ventilation is required to prevent high temperature damage, which is not preferable.

A non-woven fabric sheet for agriculture as shown in the figure in which two non-woven fabrics 1 each having m 2 and a light transmittance of 90% are superposed and heat-sealed at regular intervals by an ultrasonic welder, and an air layer 4 is formed between the non-woven fabrics 1 by the fusion-bonding portion 3. Got 2. Using this, and for comparison, when the above nonwoven fabric 1 was used as a single layer and subjected to tunneling in a tea cultivation area, the latter nonwoven fabric used as a single layer suffered frost damage, whereas the former nonwoven fabric was subjected to frost damage. Sheet 2 had no frost damage, and was able to harvest tea 10 days faster than the latter, thus accelerating the harvest time.

め、促成効果を上げることができる。Effect of the Invention As described above, the agricultural non-woven fabric sheet of the present invention is one in which a plurality of non-woven fabrics having excellent air permeability are partially heat-sealed by an ultrasonic welder or a heater including a heat generating portion and a contact portion. , As the non-fusing part shrinks due to heat as the non-fusing part shrinks due to heat as a plurality of non-woven fabrics are partially joined by heat fusion, an air layer is formed. That is, an air layer will be formed between the fused parts with the joining of a plurality of nonwoven fabrics, and the heat retaining effect will be improved in the air layer, frost damage can be prevented and the harvest will be accelerated and the forcing effect will be improved. be able to.
