Lightfastness is best described as the average number of hours of sunlight an upholstery fabric can receive before showing signs of fading. Approximately, the typical year of lightfastness is 500 hours.
We understand that for you, our customers and even manufacturers the classification system is a bit confusing. But today we will explain more about the topic.
The sun's UV and visible light rays can affect everything from leather to metal and even the fabric of outdoor furniture.
Lightfastness generally means the degree and duration to which the dye resists fading due to constant exposure to light, that is, the amount of time or life that your fabric has when exposed to direct sunlight before that begins to fade.
For the textile industry, the estimated durability of textiles is between 1 and 5 years.
In laboratories or factories, this is determined from 500, 1000, 2000 or more than 3000 hours of light resistance. But, the industry standard for interior upholstery fabric is 40 hours of light fastness.
However, it is difficult to estimate the number of hours of direct sunlight your furniture will receive, so most companies move away from this typical lightfast hour rating and offer a limited warranty of 1, 3, or 5 years on the fabric.
We have highly sun-resistant fabrics for outdoors and indoors called Revolution Outdoor . In addition, these can be washed with any detergent including chlorine, they are water repellent, they are stain resistant and have a 5-year guarantee on both our outdoor line and for decoration to avoid confusion and ensure the functionality of the fabric.
Now when the fabric label has this information you will know what it is!
