The fading problem of outdoor sunshade polypropylene fabric is a concern for many users, especially in long-term exposure to sunlight and natural environments. The fading phenomenon may affect both aesthetics and functionality.
The fading problem of outdoor sunshade polypropylene fabric is a concern for many users, especially in long-term exposure to sunlight and natural environments. The fading phenomenon may affect both aesthetics and functionality. The following are common reasons for the fading of outdoor shading polypropylene fabrics: 1 ultraviolet radiation
Reason analysis: Outdoor sunshade polypropylene fabric exposed to sunlight for a long time, ultraviolet (UV) radiation can damage the molecular structure of dyes, leading to dyeing failure and resulting in fading phenomenon. When the resistance of polypropylene fabric to ultraviolet rays is weak, the fading phenomenon is particularly obvious.
2. Climate factors
Cause analysis: Climate factors such as high temperature, humidity, and exposure to wind and sun have exacerbated the fading of polypropylene fabrics. Especially in tropical and subtropical regions, the intensity of ultraviolet radiation is higher, accelerating the fading process.
3. Fabric quality issues
Reason analysis: Improper dyeing process of low-quality polypropylene fabrics, unstable use of dyes, or dyes that are not light and sun resistant can cause the fabric to fade in a short period of time.
4. Improper cleaning
Reason analysis: Frequent use of chemical detergents, high-temperature cleaning, or improper cleaning methods (such as using bleach) can accelerate fabric fading. Especially when not following the cleaning requirements of the fabric during cleaning, dyes are easily removed.
5. Friction and Pollution
Reason analysis: During daily use, fabrics may experience uneven or faded colors due to friction or contact with pollutants such as dirt, oil stains, etc., especially when in contact with rough surfaces where friction can cause color loss.
