How stable is PLA biodegradable staple fiber under UV irradiation?

PLA biodegradable staple fiber has relatively good stability under UV irradiation. As a new type of biodegradable material, PLA itself has a certain UV resistance. When PLA is made into staple fibers, this UV resistance is retained to a certain extent. Therefore, under UV irradiation, PLA biodegradable staple fibers can maintain relatively stable performance and are not easily significantly degraded or aged due to UV radiation.
Although PLA itself has a certain UV resistance, its UV stability can be further enhanced by some technical means. For example, in the process of preparing PLA biodegradable staple fibers, an appropriate amount of UV absorbers or light stabilizers can be added. These additives can absorb or reflect UV rays, thereby reducing the destructive effect of UV rays on the fibers and further extending the service life of the fibers.
In outdoor application environments, such as outdoor textiles, sunshade materials, etc., the UV stability of PLA biodegradable staple fibers is particularly important. By adding UV absorbers or light stabilizers, as well as adopting other technical means, it can be ensured that these fibers can maintain good performance and appearance after long-term exposure to outdoor environments.
Compared with traditional synthetic fibers, PLA biodegradable staple fibers may be slightly inferior in terms of UV stability. However, due to its good biodegradability and environmental protection, its application value is still very prominent today when environmental protection requirements are becoming increasingly stringent. At the same time, by continuously improving the preparation process and adding appropriate additives, the UV stability of PLA biodegradable staple fibers can be further improved, making them more suitable for various outdoor application environments.
PLA biodegradable staple fibers have relatively good stability under UV irradiation, and their stability can be further enhanced by adding UV absorbers or light stabilizers and other technical means. This fiber has broad application prospects in outdoor application environments.
