Aging refers to the gradual degradation of a material over time, typically caused by exposure to environmental factors such as heat, humidity, and UV radiation. In the nonwovens industry, aging can be a concern for materials used in outdoor applications. Businesses in the nonwovens industry must ensure that their products have adequate protection against aging to meet the demands of their customers. This can be done by using materials with high resistance to environmental factors or by applying coatings that provide additional protection.
