AATCC 186 Weather resistance of fabrics Exposed to daylight
The AATCC Test Method 186 evaluates the weather resistance and lightfastness properties of woven, knitted, and nonwoven textiles exposed to daylight. This test is particularly relevant for materials that are expected to withstand extended exposure to natural sunlight in outdoor environments.
Textiles used in various sectors such as automotive, marine, construction, and home furnishings often require resistance to fading and degradation caused by ultraviolet (UV) radiation from the sun. AATCC 186 provides a standardized method for assessing how well these textiles retain their color and physical properties after exposure to daylight.
The test is conducted under controlled conditions that simulate real-world exposure to natural sunlight. Specimens are subjected to an accelerated weathering process, which involves exposing them to artificial light sources designed to mimic the spectral energy distribution of daylight over a defined period.
During the testing cycle, specimens undergo continuous exposure to the light source for 120 hours (5 days), followed by a conditioning period where they are stored in a dark environment. This cycle is repeated until specific criteria are met or the sample degrades beyond acceptable limits. The degradation of color and physical properties is then quantified.
Understanding the results of this test is crucial for manufacturers to ensure their products meet quality standards, especially when it comes to durability in outdoor settings. Compliance with these tests helps prevent premature aging and maintains the aesthetic appeal and functional integrity of textiles over extended periods.
