Weed-proof cloth, also known as ground cloth, is made of polypropylene (PP) or polyethylene (PE) as the main raw material, and made by plastic extrusion flat film flat yarn equipment (extrusion, film cutting, stretching, rolling) PP flat yarn or PE flat yarn (monofilament, split film yarn), the flat yarn is knitted by the plastic cylindrical knitting machine or the plastic knitting machine (water loom) through the plastic woven cloth-like products. It has the characteristics of air permeability, water permeability, filtration, isolation, reinforcement and drainage. Two products of 90 grams and 100 grams per square meter are now widely used in modern agriculture to prevent weeds, weeding, gardening and pavement leveling. The product is added with anti-aging agent and anti-oxidation (UV) agent in the process of extrusion and drawing, so that the grass-proof cloth (horticultural ground cloth) can prolong the service life in use. The general raw material (renewable material) is added with anti-aging agent and antioxidant. The life span can be up to 3 years; the life span of the new PP material can be up to 5 years after adding anti-aging agents and antioxidants; the life span of the new PE material can be up to 7-8 years after adding UV. The horticultural ground cloth is called differently in each region and industry. There are the following names: grass-proof cloth, gardening ground cloth, grass-covering cloth, weed-control cloth, grass-controlling cloth, grass-controlling mat, etc.

Features of grass-proof cloth:

1. High strength: Because it is made of PP and PE plastic flat wire, it can maintain sufficient strength and elongation in wet and dry conditions.

2. Corrosion resistance: long-term corrosion resistance in soil environments with different pH levels and rainwater.

3. Good air and water permeability: There are gaps between the radial and weft flat yarns, so it has good air permeability and water permeability.

4. Good anti-microbial performance: it will not damage microorganisms and insects.

5. Convenient construction: Because the material is light and soft, it is convenient to transport, lay and construct.

6. High breaking strength: up to 20KN/m or more, good creep resistance and corrosion resistance.

7. Anti-purple and antioxidant: Add imported UV, which has good anti-purple and antioxidant properties.

The role of grass cloth:

1. Conducive to cultivation management: most of the grass-proof fabrics are woven with one-way or two-way marking lines. When placing flower pots or arranging cultivation substrates in the greenhouse or outdoors, the construction can be carried out accurately according to these marking lines.

2. It is beneficial to the growth of plant roots and prevents root rot. This effect is also derived from the vertical and horizontal woven structure of the grass-proof cloth. This structure can ensure that no water is generated at the roots of the crops, and the air at the roots has a certain fluidity, thereby preventing root rot.

3. Prevent weeds on the ground. Because the grass-proof cloth can prevent direct sunlight on the ground (especially black ground cloth), and at the same time, the strong structure of the ground cloth itself prevents weeds from passing through the ground cloth, thus ensuring the inhibitory effect of the ground cloth on the growth of weeds.

4. Timely drain the ground water and keep the ground clean. The drainage performance of the anti-grass cloth ensures the rapid discharge of water from the ground area, and the pebble layer and middle sand layer under the ground cloth can effectively inhibit the infiltration of soil particles, thus ensuring the cleanness of the ground cloth surface.
