As a widely used synthetic fiber material, nylon mother yarn plays an important role in many industries, especially in textiles, fishing nets and industrial fabrics. However, nylon mother yarn may be affected by ultraviolet rays, oxidation and other factors in long-term use, especially in outdoor environments, resulting in a decline in performance.
Ultraviolet rays are one of the main external factors that lead to the decline in performance of nylon mother yarn. As a synthetic fiber, the molecular structure of nylon may be damaged when exposed to ultraviolet rays for a long time. Ultraviolet rays can trigger the photodegradation reaction of fibers, resulting in a decrease in fiber strength, flexibility, and even brittle cracking and breaking. In outdoor use, such as fishing nets, tents or sunshades, nylon mother yarns exposed to sunlight for a long time often have problems such as color fading and material embrittlement, which affects its service life and function.
In addition to ultraviolet rays, oxidation is also one of the important factors that cause the decline in performance of nylon mother yarn. The molecular structure of nylon mother yarn contains nitrogen and oxygen elements, which makes it possible for it to undergo oxidation reactions when it comes into contact with oxygen in the air. The oxidation process causes the molecular chain of the fiber to break, which in turn affects its strength and ductility. Especially in high temperature and humid environment, oxidation may accelerate, which has an adverse effect on the long-term use of nylon mother yarn. In some high-intensity load applications, the performance degradation caused by oxidation is particularly significant, which may cause premature failure of the product or require frequent replacement.
In order to mitigate the impact of ultraviolet rays and oxidation on nylon mother yarn, many manufacturers will adopt some technical means. For example, by adding ultraviolet absorbers or antioxidants to enhance the anti-ultraviolet and anti-oxidation properties of nylon mother yarn. This can effectively extend its service life and reduce the damage caused by ultraviolet rays and oxidation. In addition, the surface of nylon mother yarn can also be coated, which can provide a protective film to block direct contact with ultraviolet rays and oxygen, thereby further improving the durability of the fiber.
Although nylon mother yarn may experience performance degradation when facing external factors such as ultraviolet rays and oxidation, through proper design, processing and protection measures, its stability and service life in harsh environments can still be greatly improved. For products that need to be used outdoors for a long time, choosing specially treated nylon mother yarn, or regularly inspecting and maintaining it, can ensure its continued function and reduce the risk of performance degradation.
