Textiles are typically exposed to light during use, where light energy can damage dyes and cause "fading"—discoloration of colored textiles, usually resulting in lightening or darkening. How can sunlight exposure be simulated? The answer lies in using a

Polymer materials may deteriorate during synthesis, storage, processing, or end-use, manifesting as performance degradation such as yellowing, reduced molecular weight, surface cracking, loss of gloss, or severe declines in mechanical properties (e.g., im

Aging testing is a trial that simulates the performance changes of products during prolonged use or exposure to adverse environmental conditions. Such tests typically employ specialized equipment and environmental conditions to replicate harsh real-world
More
Unsaturated bonds in polymer materials absorb light energy, triggering chemical reactions that lead to adverse phenomena such as discoloration, cracking, wrinkling, and blistering. Temperature inhomogeneity caused by light exposure may also result in prod

In daily life and industrial production, numerous products are inevitably exposed to light, such as exterior wall coatings, plastics, textiles, and electronic devices. Ultraviolet (UV) radiation in sunlight, combined with high temperatures, rain, and dew,

The aging of textiles is influenced by numerous factors, and their interactions are highly complex. Consequently, current research on the aging mechanisms and testing methods for textiles, both domestically and internationally, remains insufficiently in-d
More
Textiles, as polymeric materials, are susceptible to aging due to external factors such as light radiation, temperature, oxygen, moisture, and harmful atmospheric chemicals.
