1、保温。大棚无纺布对于长波光线透射率低于塑料薄膜。因为夜间辐射区的散热主要靠长波辐射，所以，覆盖保温效果突出。

1. Heat preservation. The long wave light transmittance is lower than the plastic film in the shed non-woven fabric. Because the radiation of the radiation area at night mainly depends on the long wave radiation, the heat preservation effect is outstanding.

2、透气调湿。大棚无纺布由长丝相互铺叠成网状，有很高的空隙率，可透气、透水、自动调节湿度。

2. Moisture and moisture. The shed non-woven fabric is reticulate with each other, and has a high void ratio. It can be breathable, permeable, and automatically adjust the humidity.

3、遮光降温。采用有色大棚无纺布覆盖，具有遮光降温作用。不同颜色的大棚无纺布遮光、降温效果不同。遮光效果黑色好于黄色，黄色好于蓝色。

3, shading and cooling. It is covered by non-woven fabric of colored greenhouse and has the effect of shading and cooling. The effect of shading and cooling of different colored sheds is different. The shading effect is better than the yellow, and the yellow is better than the blue.

4、抗老化。农用大棚无纺布经过了抗老化处理，布越厚强力损失率越低。

4. Anti aging. The non - woven fabric of agricultural greenhouse has been treated with anti aging treatment, and the higher the thickness of the cloth, the lower the loss rate of the fabric.
