Today, let’s take a look at the importance of textile color fastness (color fastness to sunlight) for textiles. It relates to whether the color of your clothes is correct and will not fade.

First of all, let us understand what is the light fastness test?

The main purpose of the color fastness test is to evaluate the influence of artificial light exposure on the color fastness of the test sample.

1. The importance of color fastness test

For consumers, it is related to the wearing experience and quality of clothes

For textile manufacturers, color fastness testing is an important way to improve the core competitiveness of factories
The color fastness performance of products can be improved through testing, and the reputation of existing products can be improved
Passing tests is conducive to the sales of new products and enhances market competitiveness;
Moreover, the light fastness test is also one of the necessary conditions for the release of new products, and only those that comply with the local clothing label will be allowed to go on sale.

For designers and clothing brand owners, this is the best test to verify their creativity and ideas. Before the mass production of finished products, they need to test the prototype, which is the most reliable.

2. Is there any way to test the color fastness of clothes?

Do you put the sample to be tested directly in the sun?
Of course not, it is too time-consuming, and the environment is very limited, no one's R&D department can wait.

If you want to speed up the entire aging process, you can know the answer in a relatively short time
You need a test box for color fastness to sunlight
By simulating the natural light of the environment to accelerate the exposure process of textile products, the desired test results can be obtained in a few days of test time.

HD-E711

Air Cooling Light fastness tester designed to meet the requirements of ISO 105 B02/B04/B06 and AATCC Test Method 16 standards. The Light & Xenon Test Chamber, to determine the color fastness, aging resistance of textiles, plastics, rubber products or materials by objecting to the simulated conditions of nature weather (daylight, rain, temperature and humidity, etc.).

Color fastness testing equipment is also called xenon arc test chamber since it adopts a air-cooled long-arc-xenon lamp and rack sprays to provide both light and dark cycles and nature weather conditions. Due to its final testing purpose is to check the color fading features, people also name it as Fadeom

Therefore, lightfastness testing is essential for many textile testing. Although this is a complicated process, it is becoming easier to operate, making it easy for many manufacturers to use. No need to rely on external testing laboratories.
