During the use and storage of nonwoven fabrics, due to the influence of various external factors, some properties will gradually deteriorate, such as deterioration, hardening, stickiness, tarnish, etc., and even reduce strength and rupture, resulting in loss of use value, which is called the aging of nonwovens.

Due to the different use environments of non-woven fabrics, the requirements for aging performance are also different. The test of aging resistance is to use the artificially created natural environment to determine or observe the change in the performance of nonwovens, but many changes are difficult to quantify, generally test the change in strength before and after the change, so as to evaluate the aging resistance of nonwovens.
