Anti-aging PP non-woven fabric

In the process of use and storage of nonwovens, due to the influence of various external factors, there will be some gradual deterioration of performance, such as deterioration, hardening, hair, luster, etc., and even reduce strength and rupture, resulting in loss of use value, this phenomenon is called the aging of nonwovens.Due to the different use environment of nonwovens, the requirements of aging resistance are also different.The test of aging resistance is to measure or observe the changes in the performance of nonwovens in the artificially created natural environment, but many changes are difficult to quantify. Generally, it is to test the changes in strength before and after the changes, so as to judge the aging resistance of nonwovens.In the test of aging resistance experiment, all kinds of factors can not be considered at the same time, and only highlight the role of a factor and exclude other minor factors, so that forms many methods of testing aging resistance.T…
