Description

[Detailed Description of the Invention] The present invention relates to a crop protection covering material that is used when being applied over agricultural crops to insulate them to speed up their growth or prevent damage caused by frost.

The crop protection covering materials currently on the market are made by knitting black flat yarns in a zigzag pattern between adjacent chain warp stockinette knits, and the main fabric is black flat yarns that are not translucent. If you leave it on the crops, it will block the sunlight and prevent the crops from growing by assimilation, so you have to remove it from the crops during the day, which is very troublesome. there were.

Therefore, the present invention aims to provide a convenient and excellent crop protection covering material that uses white or transparent translucent flat threads and does not hinder the growth of crops even if it is left on the crops. It is something to do.

An embodiment of the present invention will be described below in detail with reference to the drawings.

In Fig. 1, the crop protection covering material 1 is made of white flat threads 2 extruded into a tape shape by extrusion molding of synthetic resin, and is made of synthetic resin threads, each consisting of 3 threads 3 in chain warp stockinette knitting 3a, 3b.
, pass through one chain warp stockinette knitting 3b located in the middle of 3a, and knit the chain warp stockinette knitting 3a on both left and right sides in a left and right zigzag pattern between 3a, and knit in a left and right zigzag pattern at regular intervals above and below. The right side folded portion 2' of the flat yarn 2 is pulled out to the right at appropriate intervals, and then attached to the center chain warp stockinette stitch 3b of the chain warp stockinette stitches 3a, 3b, 3a of the other group 3 adjacent to the right side. It was woven into the main land 4.

The crop protection covering material constructed as described above has the main body 4 made of white flat yarns 2 and has translucency, so it does not block sunlight. When placed over the crops, sunlight hits the crops and assimilates the crops, and at the same time, due to the insulating effect of the air contained between the flat threads 2, sunlight is absorbed from the inside of the crop protection covering. It prevents heat dissipation, keeps crops warm, prevents frost damage, and further improves the growth of crops.

In this way, since it does not cause any hindrance to the growth of crops, there is no need to remove the crop protection covering material from the top of the crops even during the daytime, and it is very convenient to leave it on and press the button.

Moreover, the crop protection covering material is knitted with chain warp stockinette 3 a t 3 b in which each set of three flat yarns 2 constitutes the main fabric 4 .

3a, the button passes through the intermediate chain warp knit stitch 3b and is held by the intermediate chain warp knit stitch 3b, so that the spacing at the center of the amplitude of the flat thread 2 is maintained constant, and the large mesh Not only can you eliminate the constriction and expansion of the stitches, but also the intermediate chain warp stockinette stitch 3b
Since it is maintained in a zigzag bent state and prevented from unraveling, there is no risk of chain damage even if it is cut from any direction.

In the above embodiment, the folded portions 2 are pulled out to the right at appropriate intervals, and the chain warp stockinette knitting 3a of the other group 3 adjacent to the right side is
Because it is knitted into the center chain warp stockinette knitting 3b of 3b and 3a, this drawer part 2
', the effect of preventing chain breakage of the flat yarn 2 is further enhanced and excellent.

In the above embodiment, white flat threads were used to make the main fabric 4 translucent, but transparent flat threads may also be used, or as shown in FIG. A flat yarn 7 on which white lines 6 are formed may also be used.

Further, transparent flat threads and white flat threads may be alternately knitted.
