【考案の詳細な説明】
本考案は果実の栽培又は保護の効果に優れ、かつ袋とし
て耐久性に優れた果実用不織布に関する。[Detailed Description of the Invention] The present invention relates to a nonwoven fabric for fruit that is excellent in fruit cultivation or protection effects and has excellent durability as a bag.
従来から果実用袋としては、紙を糊付等により成形した
ものが広く使用されているが、病害虫や風雨に対する効
果については十分ではない。Conventionally, fruit bags made of paper formed by gluing or the like have been widely used, but they are not sufficiently effective against pests and wind and rain.
特に湿潤時の強度が小さいのが欠点であった。The drawback was that the strength was particularly low when wet.
この改善策として、紙を種々の薬剤処理により補強する
方法が実施されているが満足でないことから、不織布を
用いた果実用袋がクローズアップされてきている。As a countermeasure to this problem, methods of reinforcing the paper by treating it with various chemicals have been implemented, but these have not been satisfactory, and fruit bags using nonwoven fabrics have been attracting attention.
しかしながら、単一素材の不織布を袋状に成形加工する
ことは多くの場合、非常に難しい。However, in many cases, it is very difficult to form a single material nonwoven fabric into a bag shape.
これはヒートシール又は高周波ウエルダーにより接合は
可能であるが、同時に接合部の組織の変化を誘発し著し
く劣化するため使用に耐えないものになってしまうから
である。This is because although it is possible to join by heat sealing or high-frequency welding, it also induces changes in the structure of the joint and causes significant deterioration, making it unusable.
この問題を解決するため、一部には不織布自体を複合素
材化することにより不織布単独での成形を可能にした例
もあるが、性状が変化することから多用性に欠けること
、果実用袋としての形態安定性に欠ける等の欠点がある
。In order to solve this problem, there are some examples of making nonwoven fabric itself into a composite material, making it possible to mold the nonwoven fabric alone, but it lacks versatility because its properties change, and it is not suitable for fruit bags. It has drawbacks such as a lack of morphological stability.
他方、この単一素材不織布を袋状に縫製加工あるいは糊
付加工することも可能であるが加工能率、コスト、強度
の点から実用には至っていない。On the other hand, it is also possible to sew or glue this single-material nonwoven fabric into a bag shape, but this has not been put to practical use in terms of processing efficiency, cost, and strength.
本考案は単一素材よりなる不織布の接合に際し、中間体
として低融点の熱可塑性フィルムあるいは不織布を介在
させることにより従来より使用されている装置を用いて
容易に、かつ強力に接合し果実用不織布袋を得るもので
ある。The present invention is capable of easily and strongly bonding nonwoven fabrics made of a single material by interposing a thermoplastic film or nonwoven fabric with a low melting point as an intermediate using conventional equipment. What you get is a bag.
即ち、本考案による果実用不織布袋は、紙袋又は複合素
材による単独成形不織布袋に比し、接合部の強力は著し
く大きく、シかも連続成形により安価に供給するもので
ある。That is, the nonwoven bag for fruit according to the present invention has significantly greater strength at the joint than a single molded nonwoven bag made of a paper bag or a composite material, and can be supplied at a low cost by continuous molding.
加えて、不織布のもつ外的環境からの保護及び果実の商
品価値の向上も大きな特徴である。In addition, the nonwoven fabric's protection from the external environment and improvement in the commercial value of fruit are also major features.
本考案に使用する不織布を構成する繊維素材としては通
常の不織布に用いられる天然繊維、再生繊維、半合成繊
維あるいは合成繊維であり合成繊維の場合は単一素材で
ある。The fiber materials constituting the nonwoven fabric used in the present invention include natural fibers, regenerated fibers, semi-synthetic fibers, or synthetic fibers used in ordinary nonwoven fabrics, and in the case of synthetic fibers, it is a single material.
又本考案に用いる不織布は短繊維不織布、あるいは長繊
維不織布である。Further, the nonwoven fabric used in the present invention is a short fiber nonwoven fabric or a long fiber nonwoven fabric.
中間体として使用する熱可塑性物質はポリオレフィン、
ポリ塩化ビニル、ポリ塩化ビニリデン、低融点ポリエス
テル、低融点ポリアミド等で、フィルム状あるいは不織
布状のものである。The thermoplastics used as intermediates are polyolefins,
Polyvinyl chloride, polyvinylidene chloride, low melting point polyester, low melting point polyamide, etc., in the form of a film or nonwoven fabric.
本考案による果実用不織布袋の形成力法は、第１〜２図
に示す如く具体的には不織布１と不織布１′の間に中間
体として上述の熱可塑性物質のフィルムあるいは不織布
３を置き、ヒートシーラー又は高周波ウエルダーにより
２，２′部分を接合する。Specifically, the method of forming a non-woven fruit bag according to the present invention, as shown in FIGS. 1 and 2, involves placing the above-mentioned thermoplastic film or non-woven fabric 3 as an intermediate between the non-woven fabric 1 and the non-woven fabric 1', The 2 and 2' portions are joined using a heat sealer or high frequency welder.
不織布及び中間体は予め希望する大きさに裁断すること
も、接合と同時に袋状に裁断することもできる。The nonwoven fabric and the intermediate body can be cut in advance to a desired size, or can be cut into a bag shape at the same time as bonding.
第３図は袋の全面に熱可塑性物質３′を重ねて２″、２
″部を接合した場合を示す。Figure 3 shows that thermoplastic material 3' is overlaid on the entire surface of the bag.
This shows the case where the ″ section is joined.

ｎｔ部を接合した場合の袋を示す。FIG. 1 is an external view of an example of a nonwoven bag for fruit according to the present invention, where 1 indicates the nonwoven fabric as a material, and 2 indicates the joint thereof. Figure 2 is an enlarged cross-sectional view on the AA edge line of the bag in Figure 1;
indicates a thermoplastic material. Figure 3 shows a layer of thermoplastic material 3' on the entire surface of the bag.
The bag is shown when the nt part is joined.
