織布は重すぎるうえ、高価である欠点を有する。On the other hand, there is a growing demand for heat and moisture retention that is easy to carry and does not require large side effects. In many cases, the purpose is to delay the shipping of agricultural products and prevent quality deterioration before harvest. In this case, the currently widely used nonwoven fabrics have the disadvantage of being too heavy and expensive.
このような問題を解決するため、不織布の軽重化の検討
が行われているが、概して不織布は目付けを軽くすると
急速に不均一化する傾向があるうえ、材料が少なくなる
わりには安価にならない七１ｕ点があった。In order to solve these problems, studies are being conducted to make nonwoven fabrics lighter and heavier, but in general, nonwoven fabrics tend to become uneven quickly when their basis weight is reduced, and they do not become cheaper even though fewer materials are used. There was a 1u point.

I observed 571 and 311 side by side with those that don't cover anything until early 311. Once a week, the coating 3 was removed and the condition of the Chinese cabbage was examined. No particular abnormality was observed in those using protective sheets until early February, and deformation due to damage was observed after mid-February. On the other hand, those who did not use the promotion sheet received 1
The outer leaves began to wither in mid-February, and by early January, the dead parts had spread to the head part, and it was determined that the plant had almost lost its commercial value.

。Example 4 A mixture of 30% by weight of nylon 6 with a molecular weight of 15,000 and low density polyethylene with MFRll, 0 was extruded through a linear gouer and solidified, followed by an embossing roller with a surface temperature of 205°C. The material was sandwiched between an anvil roller with a flat surface and formed to leave an approximately square raised portion, and then two-wheel stretching was performed. The basis weight of the obtained porous film was 5 g/2, the thickness at the thickest point was 0.05 am, and the pore density was 12/C ring 2.
この多孔フィルムも直接被覆する植物保護シートとして
、実施例 １と同様に優れた性能を示した。This porous film also showed excellent performance as in Example 1 as a plant protection sheet for direct coating.
