High-tech fabrics protecting agriculture: Modern agrotextiles from greenhouses to silage

In modern agriculture, high and stable crop yields and the healthy development of animal husbandry rely on the support of technology. A special type of fabric plays a crucial role. These are no longer traditional clothing materials, but agrotextiles (agrotextiles) widely used in crop protection, greenhouses, and silage. These high-tech fabrics are quietly transforming agricultural production models.

1. Crop Protection

Purpose: This is the most fundamental and important function of agricultural textiles. Its purpose is to create an optimal microenvironment for crops throughout their growth cycle, protecting them from various biotic and abiotic stresses.

Applications:

Insect Netting: Covering crops creates a physical barrier, effectively preventing pests and birds, and significantly reducing pesticide use.

Weed Control Sheeting: Lay between crop rows or under trees to suppress weed growth, reducing herbicide use and manual weeding costs.

Hail/Frost Netting: Used in high-value crop areas such as orchards, it mitigates damage from severe weather such as hail, low temperatures, and frost.

Shade Netting: Provides shade for shade-loving crops or seedlings during the hot summer months, reducing transpiration and preventing sunburn.

Crop Protection: High-density polyethylene (HDPE) woven netting and non-woven fabrics are lightweight, high-strength, tear-resistant, and weather-resistant.

Adjustable Breathability and Light Transmission: Designed with varying shade levels and air holes to meet the needs of different crops. UV resistant (UV stable): Resists degradation after prolonged outdoor use.

Durable and recyclable: Extends service life and reduces long-term costs.

2. Agriculture greenhouse
Fabric: Polyethylene (PE) film: The most common and economical choice, especially multifunctional PO film (polyolefin, a high-grade PE film).

Ethylene tetrafluoroethylene copolymer (ETFE) film: A high-end material, though expensive, but with exceptional performance, its light transmittance, durability, and self-cleaning properties far surpass those of PE film.

Polycarbonate (PC) sheet: A mid-to-high-end greenhouse material, typically a hollow multi-layer sheet with excellent thermal insulation and impact resistance (hail protection).

Application: As the core of modern facility agriculture, greenhouse covering materials are a typical example of agricultural textiles, directly determining the greenhouse's lighting, thermal insulation, and humidity performance.

Application scenarios:

Covering materials: Modern greenhouses are no longer limited to traditional glass and ordinary plastic film. Multifunctional PO film, ETFE film, and double-layer inflatable covering materials are widely used. They form the "skin" of the greenhouse and serve as the first line of protection for growing crops. Greenhouse: Multifunctional PO film, ETFE film, and polycarbonate (PC) panels. High light transmittance ensures efficient crop photosynthesis.

Insulation: Contains a heat-insulating agent to reduce heat loss at night.

Anti-drip and anti-fog: Prevents condensation from dripping and burning crops or causing disease.

Long-lasting and weather-resistant: Anti-aging, anti-static, and dust-resistant, maintaining consistently high light transmittance.

3. Silage cover

Material: Polyethylene (PE) stretch film: This is the predominant material for round silage bales. Typically available in black, white, or green, it exhibits excellent stretchability and resilience.

Polyethylene (PE) co-extruded film silage bags: Used for bagged silage, these bags are made from a multi-layer PE composite, offering high strength and excellent oxygen barrier properties.

Application: Silage is a key technology for preserving the nutrients of green fodder and ensuring a balanced year-round feed supply for livestock. Sealing is crucial for success in this process.

Applications:

Silage film/cloth: Used to wrap silage (such as corn stalks and pasture grass), creating an anaerobic environment to promote lactic acid fermentation and prevent mold and nutrient loss. Common forms include:

Silage wrap: Used for round silage bales.

Silage bags: Large plastic bags used to store large quantities of silage.

Silage sheet/cover: Covers the top of silage stored in a silo, with the edges pressed tightly with a weight to create a seal. Silage: High-strength polyethylene (PE) stretch film and co-extruded film. High tensile strength: Resists tearing during wrapping.

Excellent sealing and adhesion: Layers adhere tightly, effectively isolating the film from air.

Puncture resistance: Prevents sharp objects like straw from puncturing the film.

Weather resistance: Withstands sun and rain, ensuring stability throughout the fermentation process.
