It is formed into a net by flat weaving, kami weaving, and Russell knitting using flat yarn as weft and monofilament as warp. These are in high demand because they can freely set the light-shielding rate and the heat-shielding rate depending on the thickness, interval, arrangement, and color of the monofilaments and can obtain a remarkable effect.

かかる作業になりつつある。However, since synthetic resins such as polyvinyl chloride and polyethylene are used for flat yarns and monofilaments, they must be properly disposed of after use. In other words, they are collected and incinerated, but in recent years, if they are indiscriminately incinerated, there is a problem that harmful gas may be generated and disposal is difficult. In recent years, especially in recent years, the aging of agricultural workers has advanced, and collecting and disposing of used agricultural nets is becoming a burdensome operation.

One is an agricultural net formed of a biodegradable material that is degraded in a natural environment. For example, the warp may be formed of a biodegradable material, the weft may be formed of a biodegradable material, or both the warp and the weft may be formed of a biodegradable material. Is preferably formed of a biodegradable material.

成り立つ利点も有するからである。In order to obtain an agricultural net having necessary conditions such as strength, the biodegradable material should be composed of polylactic acid, especially a biodegradable material mainly composed of poly-L-lactic acid. Good. In this case, because of the raw material (starch) of polylactic acid, it is possible to reduce the amount by a predetermined treatment, that is, hydrolysis or crushing under high temperature and high humidity, and then compost it. This is because these have the advantage that they are further utilized for growing plants and that circulation in the natural world is established.

An agricultural net having an appropriate light-shielding rate and heat-shielding rate is obtained by setting the size of the eyes and the like. In such agricultural nets, at least one of the warp and weft is biodegradable, so if it is buried in the soil after a certain period of use up to its useful life, unless it is laid on the ground and used, Biodegradable parts are broken down from natural blood and returned to the soil.

しい。[0011] Poly-L-lactic acid is an optical isomer of poly-D-lactic acid, and a polylactic acid flat yarn or a polylactic acid monofilament is produced using these copolymers as a main component.
At this time, since the ratio between the L-form and the D-form affects the biodegradability, it is preferable to use a material whose optical purity of the L-form is in the range of about 95.0 to 99.5%. If the purity of the L-form is lower than the above range, the biodegradation rate will be high, and if the purity of the L-form is higher than the above range, the biodegradation rate will be low. Also,
In order to give the strength and elasticity required for the agricultural net 1, it is preferable to use a material having an average molecular weight of polylactic acid of 70,000 or more.

If the polylactic acid monofilament or the polylactic acid flat yarn constituting the above is used for a predetermined endurance period, it may be removed, collected and buried in the soil at a predetermined place. It is gradually degraded by microorganisms in the soil and all disappears. In the case where a flat yarn or monofilament made of polylactic acid is used, composting can be performed by introducing a composting device or establishing a recovery system.
