Non-woven fabric is a new type of environmental protection material, which is widely used. There are many ways to test, such as thickness, tension, etc. Today, let's take a look at the hygroscopic performance of non-woven fabrics.
The use of non-woven fabric in greenhouses can reduce water droplets on crop leaves, thereby preventing crop disease and fruit rot. After sunlight during the day, the moisture of the non-woven fabric will evaporate, and at night, it can absorb the moisture evaporated from the leaves. Especially in recent years, its coverage test has been accepted and has a good heat insulation effect.
After covering the soil with plastic film, the nonwoven fabric can prevent soil heat from radiating outward, which can increase soil temperature by 3 to 4 percent. , after covering the soil with plastic film, it can reduce the evaporation of water, maintain a certain soil moisture and reduce the water number. Watering can open the trenches between the rows, and the water penetrates laterally to the roots under the canopy so that the soil layer under the plastic film is always loose and not compacted.
Through the above explanation, the hygroscopicity of non-woven fabric is very obvious, do you feel it?
