Performance Characteristics
- Weed - control Performance
- The woven weed - control fabric can effectively inhibit weed growth. Its main principle is to cover the soil surface and block sunlight from reaching weed seeds and seedlings, so that weeds cannot carry out photosynthesis, thereby achieving the purpose of weed control. Its light - shielding rate can usually reach 85% - 95%, providing a good weed - free growth environment for plants.
- Due to the relatively tight structure of the woven weed - control fabric, it can also prevent the spread of weed seeds to a certain extent. It can prevent external weed seeds from falling into the soil and also reduce the spread of existing weed seeds in the soil due to factors such as wind and water.
- Physical Properties
- High Strength: The woven weed - control fabric has excellent tensile strength and tear strength. Its tensile strength is generally between 20 - 100 kN/m and can withstand a large pulling force without easily breaking. The tear strength is usually between 200 - 1000 N, which enables it to remain intact and not easily damaged during installation or when subjected to external forces such as being scratched by farm tools or trampled by animals.
- Good Stability: Due to its woven structure, the woven weed - control fabric is relatively stable in terms of size. It will not easily deform or shift like some thinner materials and can remain in the laid position for a long time, providing long - lasting protection for weed control.
- Water and Air PermeabilityLong Service Life: Under normal usage conditions, the woven weed - control fabric has a long service life, generally up to 3 - 5 years. This is mainly due to the stability of its material and its good anti - aging performance. The added ultraviolet absorbers and antioxidants can effectively delay the aging process of the material, enabling it to play a weed - control role in the outdoor environment for a long time.
- The woven weed - control fabric has a certain water - permeability. The gaps in its woven structure allow water to pass through, enabling rainwater or irrigation water to penetrate into the soil and keep the soil moist. The water permeability rate is generally between 0.5 - 5 cm/s, and the specific value depends on factors such as the tightness of weaving and the thickness of the flat filaments.
- The air permeability is also reasonable. Air can circulate between the soil and the outside through the pores of the woven fabric, which is beneficial to the respiration of soil microorganisms and the aerobic respiration of plant roots, maintaining the ecological balance of the soil.
