Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cover for storing sugar beets, particularly a cover for storing sugar beets used to preserve sugar beets piled up in the open after harvesting. .

[Conventional technology]

Conventionally, this type of cover for sugar beet storage has been used in northern countries with harsh climate conditions to preserve sugar beets harvested in autumn in open piles until spring under bitterly cold conditions. Conventionally, cover fabrics made of fabrics woven from flat yarns in the warp and weft have generally been used.

[The problem that the idea attempts to solve]

However, since the above-mentioned cover material has poor heat retention, it has caused problems such as frostbite on the surface layer of stored sugar beets. Therefore, cover fabrics made of fabrics woven with warp and weft yarns, which have excellent heat retention properties, have come to be used. It is necessary to stack a plurality of sheets, and as a result, not only the handling such as covering work is complicated, but also it cannot be said to be economical.

The present invention has been devised to eliminate the drawbacks of the conventional products described above, and aims to provide a cover material for storing sugar beet which has the above-mentioned ease of handling and excellent heat retention.

[Means to solve the problem]

This invention was devised in view of the above, and
In a cover material for sugar beet storage made of a fabric woven with expanded expanded yarns as warp and weft yarns, the front and back surfaces are bound together with a binding yarn consisting of a part of the threads of the fabric or an inserted yarn. This cover material for sugar beet storage is characterized in that it has a double-woven structure made of woven fabric, and a synthetic resin sheet is layered on the surface of the woven fabric via an adhesive layer.

〔Example〕

Hereinafter, an embodiment of the present invention shown in the drawings will be described. Fig. 1 is a perspective view showing an embodiment of the cover material for storing sugar beets of the present invention, and Fig. 2 is a partially enlarged sectional view of the same. In the figure, 1 is a fabric woven with polypropylene foam spread yarn as the warp and weft, and a front fabric 12, a back fabric 12, in which a part of the yarn of the fabric 1 is bound as a binding yarn 11, 13 double weave structure, 2 is ethylene coated on the surface of the outer fabric 12. An adhesive layer made of vinyl acetate copolymer film, which is a synthetic resin sheet 3 to be described later.
The synthetic resin sheet 3 is made of a polyethylene sheet and is layered on the surface of the fabric 1.

[Effect of idea]

As is clear from the above, the cover fabric for sugar beet storage of the present invention is a cover fabric for sugar beet storage consisting of a fabric woven with expanded expanded yarns as warp and weft yarns, in which the fabric is a part of the threads of the fabric, Alternatively, it has a double-woven structure consisting of front and back fabrics connected by binding yarns consisting of inserted yarns, and a synthetic resin sheet is layered on the surface of the fabric via an adhesive. Compared to conventional products, the heat retention effect of the front and back fabrics of the yarn itself, the air layer formed between the front and back fabrics, and the cold air blocking effect of the synthetic resin sheet layered via adhesive Heat retention is significantly improved, and since these multiple layers of fabric and sheet are integrally layered, work efficiency is improved, such as halving the work required to hang the sheet.
