The Importance of Color Fastness Testing
Colorfastness refers to the washing and friction resistance of textiles. The quality of color fastness is directly related to the health and safety of the human body. In the process of using the product with poor color fastness, when the products across the rain and the sweat, which will result in the pigment on the fabric fading off, even the molecules and heavy metal may be absorbed by the human body through the skin and endanger the health of the skin. On the other hand, cloth with poor color fastness will cause other clothes to be stained with color and dye other clothes when washed with other clothes.
What is the difference between water fastness and washing fastness?
Water fastness is the color fastness of water immersion. In the testing, the textile specimen and the specified lining fabric are laminated together and immersed in water. After squeezing out the water, place them in the middle of the two plates and offer a certain pressure. Finally, use the gray sample card or instrument to assess the color change of the specimen and lining staining.
Washing fastness is also called soap fastness. In the testing, sewn the textile specimen and the specified lining fabric together. Then place them in soap or a mixture of soap and anhydrous sodium carbonate. Finally, use the gray sample card or instrument to assess the color change of the specimen and lining staining after a specific washing, cleaning, and drying with the original sample as a reference. In short, the sample needs to be immersed in the water in the former testing while it needs to be washed with soap in the latter testing.
Test Standard for Colour Fastness to Washing of Textiles
The washing fastness of textiles refers to the ability of the textile to maintain the original color under the washing condition, that is, the ability to not fade and change color. ISO 105C01-C05 provides several test methods for color fastness to washing, covering the range from mild to intense washing operation, as a classic colorfastness test method, which is still widely used today. The determination of color fastness to washing of the whole cotton fabric using washing fastness test ISO 105-c03 method, China’s GB/T 3921 3-1997 standard is based on the modification of the formulation, so its technical content and international standards are not different, applicable to any form of textiles.
In addition to the above 2 standards, there are many international standards on the testing of color fastness to water, such as AATCC 61-1A of the US, British BS 1006-C01, ISO 105-c06 of the ISO, JIS L0844 of Japan, etc.
Test Procedure

A: The washing fastness of textiles refers to the ability of textiles to not fade and change color after washing or dry cleaning.
Q: How to improve the color fastness of washing in industrial production？
A: The most direct solution to fading in production is to use color fixers, such as resins or quaternary ammonium salts, which strengthen the connection between the dye and the fiber, enhancing the fixing power and thus reducing fading. Alternatively, a more reactive or direct dye can be used to improve the color fastness to washing and reduce fading. What’s more, you can click here and learn more.
Q: What is the difference between wash fastness testing with soap and wash fastness testing with water?
A: Wash fastness testing with soap focuses on simulating the fading of textiles during routine low-temperature washing, using soap or detergent. In contrast, wash fastness testing with water simulates high-temperature washing, suitable for more demanding environments, such as industrial laundering. The primary difference between the two lies in the washing temperature and conditions; the former is suitable for home use scenarios, while the latter is more appropriate for high-demand cleaning applications.
Q: How many types of Colour Fastness Tester are there?
A: There are several types of Colour Fastness Testers, including washing fastness testers, light fastness testers, rubbing fastness testers, friction fastness testers, perspiration fastness testers, water fastness testers, bleach fastness testers, and chemical fastness testers, each designed to evaluate specific aspects of color retention under various conditions.
Q: Why SmartDispen Detergent Dispenser is important for color Fastness to Washing testing?
A: The SmartDispen Detergent Dispenser is an essential device for color fastness to washing testing, designed specifically for this purpose.
SmartDispen enhances sample preparation efficiency by six times, making the testing process faster: with three independent stations, it can prepare different soap solutions, so for 24 test cups, traditional manual preparation takes over 20 minutes, while SmartDispen only requires 3 minutes.
The testing is also more reliable, as it automatically weighs the samples, dispenses the soap solution according to the bath ratio, stirs automatically, adds water, and outputs the set number of steel balls, effectively preparing all the necessary samples for wash fastness testing in one go, thus reducing human error in the process.
Q: What types of fabrics can be tested for this Washing Fastness Tester?
A: The WashTrue Washing Fastness Tester is suitable for testing a variety of fabric types, including natural fibers like cotton, linen, silk, and wool; synthetic fibers such as polyester, nylon, acrylic, and spandex; as well as blended, knitted, and woven fabrics, providing reliable results for quality control in textile manufacturing.
Q: What scale is color fastness to washing rated on?
A: Color fastness to washing is rated on the gray scale, which is a standardized method used to evaluate the degree of color change and staining after washing tests. The gray scale typically ranges from 1 to 5, where 1 indicates very poor fastness (significant color change or staining) and 5 signifies excellent fastness (no noticeable change or staining).
Q: What are the testing conditions for fabric’s color fastness to wash?
A: Washing colorfastness is tested under controlled conditions that include varying washing temperatures (typically from 30°C to 60°C or higher), standardized washing times, specific detergent types and concentrations, mechanical agitation levels, clean water quality, consistent sample preparation, rinsing conditions, and standardized assessment criteria for evaluating color change and staining.
Q: What factors can affect wash fastness test results?
A: Factors such as the type of dye used, fabric composition, washing temperature, detergent type, and washing machine settings can all influence the wash fastness results.
Q: What are the reasons for failing the colour fastness to washing?
A: Inappropriate Dye Selection
Using low-quality dyes or dyes that do not have sufficient affinity for the fabric can lead to fading or loss of color during washing.
Dyeing Process Issues
Poor control during the dyeing process, such as temperature, time, and pH levels, may result in uneven dyeing or weak dye adhesion.
Fabric Material
Certain materials (such as some synthetic fibers) may have a weak adsorption capacity for dyes, leading to dye loss during washing.
Washing Conditions
Improper washing conditions, including temperature, duration, detergent type, and concentration, can affect color fastness performance. High temperatures or strong alkaline detergents may accelerate dye fading.
Mechanical Agitation
Excessive mechanical agitation during washing can cause significant friction on the fabric surface, accelerating color loss.
Post-Treatment Processes
Post-treatment processes (such as softeners or wrinkle-resistant treatments) may affect the dye's durability. Improper post-treatment can lead to dye loss or fading.
Storage Conditions
Exposure to strong light, high temperatures, or humid environments during storage can decrease color fastness.
Non-Compliance with Testing Standards
If the wash fastness test is not conducted according to relevant standards, it may lead to inaccurate results and misjudgment of color fastness levels.
Q: How long does it take for soap to dissolve at different temperatures?
A: The dissolution times for soap at various temperatures are as follows:
40°C: 87-93 minutes
50°C: 23-24 minutes
60°C: 16-17 minutes
90°C: 6-7 minutes
Q: What issue may occur after wash fastness testing?
A: After wash fastness testing, some samples may exhibit residual white deposits, which can affect the assessment of color change levels. These deposits may result from undissolved soap or other substances, leading to inaccuracies in evaluating the fabric's color fastness performance.
Q: What solutions can improve color fastness?
A: To address substandard color transfer, consider the following solutions:
Improve fabric dyeing performance, such as dye penetration and fixation, and enhance soap washing and reduction cleaning to effectively remove floating color.
Use fixing agents to enhance the fabric's wash and water color fastness.
Employ appropriate additives to prevent sweat from damaging the dye structure.
