Spunbond non-woven fabric has been widely used as a film covering material in agriculture. The ability of water and air to freely pass through makes it very popular in agriculture as a covering material for greenhouses, lightweight greenhouses, and to shield seedlings anytime, anywhere.
Let’s consider the specific applications of agricultural spunbond nonwoven fabrics with different densities. Don’t forget that for all usage options, the smooth side of the fabric should face outward, while the suede side should face the plants. Then, on rainy days, excess moisture will be lost, and the internal fuzz will actively retain moisture, creating a favorable climate for the plants.
17gsm
The thinnest and lightest. In horticulture, it is used to directly cover seedbeds and seedlings on soil or plants. The ground beneath it heats up faster, and the unbreakable buds that appear freely lift up a layer of spider mesh insulated light cloak. To prevent the canvas from being blown away by the wind, it should be compressed with stones or wooden boards or fixed with agricultural canvas specific anchors.
When irrigating or applying dissolved fertilizers, the coating cannot be removed – the water flow will not lower it at all. This type of spunbond non-woven fabric can withstand frost as low as -3 ° C, perfectly transmitting light, air, and moisture, creating a microclimate favorable to plants, mitigating temperature changes, and reducing water evaporation in the soil. In addition, it perfectly prevents pests. It can only be removed during harvest. For crops pollinated during the flowering period, the covering should be removed. Similarly, this type of agricultural textile can be used in unheated greenhouses during spring frost periods to heat beds.
30gsm
Therefore, a more durable material is not only suitable for sheltering beds, but also for building small greenhouses. Reliable protection of plants from cold, frost as low as -5 ° C, as well as damage from insects, birds, and hail. Effectively preventing high temperature and overheating, reducing the evaporation of water in the soil, and promoting its optimal moisture content. Larger crops such as shrubs and fruit tree seedlings can also be insulated with this material.
42gsm
Soft and durable spunbond non-woven fabric. Easy to cover large areas, such as lawns and simulate snow cover, especially in autumn and early spring. It can effectively transmit light and water, protecting seedlings, shrubs, and trees from short-term frost as low as -7 ° C.
This density of canvas is commonly used as a covering material for curved small frames or tunnel style greenhouses. Ideally, use smooth pipes to create arcs and secure them with circular clips from the greenhouse, making it easy to disassemble. Thanks to the characteristics of agricultural textiles, a greenhouse microclimate is formed inside, which is most suitable for plant photosynthesis. The walls of this greenhouse will not form condensation water, and plants will never ‘cook’ in it. In addition, this thickness of non-woven fabric can resist hail and heavy rain.
60 and 80gsm
This is the thickest and most durable white non-woven fabric. Its main scope of application is greenhouses. The geometric shape of the greenhouse provides conditions for the rolling of snow, which cannot be removed in winter, and can withstand 3-6 seasons, which corresponds to high-quality greenhouse coating samples. However, combining agricultural non-woven fabric with film can achieve the best results.
Due to the better frost resistance of the film in spring, it is convenient to provide a quick release clip in the design of the greenhouse frame. You can use it to quickly install or remove the film and agricultural textile coating in any combination from the right side. Therefore, any conditions can be created – from maximum thermal protection in two layers to a fully open greenhouse framework.
In agricultural applications, the width of non-woven fabrics on the market is generally limited to 3.2 meters. Due to the wide agricultural area, there is often a problem of insufficient width of non-woven fabrics during the coverage process. Therefore, our company has conducted analysis and research on this issue, innovated in technology, and developed a non-woven fabric ultra wide splicing machine. The non-woven fabric can be edge spliced, and the width of the spliced non-woven fabric can reach tens of meters. For example, a 3.2-meter non-woven fabric can be spliced in five layers to obtain a 16 meter wide non-woven fabric. With ten layers of splicing, it can reach 32 meters… Therefore, by using non-woven fabric edge splicing, the problem of insufficient width can be solved.
Multi layer non-woven fabric edge splicing, unfolded non-woven fabric width can reach tens of meters, ultra wide non-woven fabric joining machine!
