Weathering and Light Stability Testing for Fabrics and Textiles


Q-Lab is the world leader in providing lightstability and weathering test equipment and services to the textile and fabric industry for apparel, fashion, commercial, and industrial applications.

Why Test?

Any items that see sunlight, moisture, and heat are subject to the damaging forces of nature. Textile materials can be susceptible to loss of color and tensile strength when exposed to sunlight outdoors and behind window glass, as well as in high-humidity environments.

Will your apparel and fashion fabrics retain their color? Will your industrial and commercial fabrics and textiles last outdoors? For how long? Does your new raw material supplier have the same quality as your previous one? Has something changed in your process that might affect its long term durability? Don't guess when you can test.

Introduction to Weathering and Lightfastness

Q-Lab serves hundreds of customers who manufacture or buy textiles for a variety of applications, including:

  • Apparel Fabrics    
  • Carpet 
  • Floor Coverings    
  • Military & Industrial
    Tents & Covers    
  • Pool Covers
  • Window Treatments
  • Parachutes
  • Automotive Interiors
  • Awnings
  • Woven Polypropylene
    Bags (FIBC)
  • Outdoor Furniture
  • Geotextiles

Common lightfastness tests for apparel and design fabrics are performed in Q-SUN xenon test chambers, recognized by all major international standards organizations, including ISO and AATCC. For textiles and fabrics designed for long-duration outdoor use, both the Q-SUN xenon test chamber and QUV accelerated weathering tester are good choices for simulating outdoor conditions in the laboratory.

Our Exposure Testing Services for Fabrics and Textiles

Florida & Arizona Natural Outdoor

While accelerated lightstability and weathering chambers are a key weapon in the fight against the forces of sunlight, heat, and moisture, nothing beats the real thing: outdoor testing in one of Q-Lab benchmark outdoor testing facilities. Q-Lab's South Florida and Arizona desert sites provide the ultimate test of your textile product's outdoor durability using natural conditions.

Accelerated Laboratory Weathering

Accelerated laboratory weathering testing is an efficient and effective way to evaluate the durability of textile materials, designed to accelerate your weathering testing process to provide you with accurate and reliable answers.

Explore Solutions

Q-Lab's accelerated weathering testers simulate the primary light and weathering conditions that degrade all types of fabrics and textiles, causing:

  • Fading
  • Color Change
  • Yellowing
  • Loss of Tensile Strength
  • Decrease in Flame Resistance
  • Loss of IR Absorption or Reflection

A variety of international test standards are used to evaluate fabrics and textiles' weathering resistance and light stability. Visit Q-Lab’s Standards Search page to browse standards and find the right test for your product.

Additional Testing for Fabrics & Textiles

Under Glass Exposure

Glass generally filters out the most damaging short-wavelength UV light, but interior-use materials still can degrade due to UVA and shortwave visible passing through window glass. Under glass exposures are available at Q-Lab’s benchmark sites in Florida & Arizona.

Automotive Interior Materials (AIM) Box

AIM Boxes are under-glass enclosures that simulate the sunlight and heat found inside an automobile. These important environmental stressors result in color change, cracking, peeling, oxidation, or loss of strength of materials in car and truck interior fabrics. AIM boxes can accelerate these stressors by tracking the sun throughout the day. Three-dimensional fabrics like seat cushions as well as flat specimens like interior trim can be tested.
