Anti aging nonwoven exposed to wind and rain, sun and rain can also be used normally, these non-woven fabrics can resist sun and weathering. To improve the aging resistance of nonwoven fabric bags, first of all, from the production process, the general non-woven manufacturers in Shandong will add some anti UV additives in the process of non-woven fabrics, but there is no special treatment in the later stage, so the anti-aging properties of non-woven fabrics can only be maintained for a very short time.
Some anti-aging nonwovens are used as soilless culture. If they are used in water, they need water to penetrate. Therefore, when the nonwoven fabric is doing well in anti-aging, it needs adding some hydrophilic coatings, and then adding the finishing liquid and auxiliaries, and finally drying.
