4.55 (11 reviews)

The WashTrue Washing Fastness Tester is mainly used to test the color fastness to washing or dry cleaning, i.e., the ability of textiles not to fade or change color after washing or dry cleaning.

The WashTrue Washing Color Fastness Tester adopts a smart temperature control algorithm to ensure that the washing color fastness test meets the test standards and the results are reliable. This Launder-Ometer applies to standards such as ISO 105 C06:2010, AATCC61-2013e3, GB/T 12490-2014, M&S C4A, AATCC190-2010e2 (2016) e2, NEXT TM 02, etc. To speed up the sample preparation for washing fastness testing, you also need a machine named SmartFill Liquid Filling Machine (figure 2).

A series of testing operations can be completed on the touch screen, such as selecting standards, parameters, time, and temperature settings, adding water, draining water, etc., it is smart and efficient, and the buzzer alarms automatically when the color fastness to washing test is completed. The WashTrue also has multiple safety designs and can run long time with low noise.





Smart, Easy to use and Efficient

The smart screen interface allows direct access to a variety of operations: selection of test standards, customization of test parameters, temperature calibration, selection of temperature increase rate, setting of time, heating temperature, etc. So it is very convenient to do the color fastness test of fabric.


Precise temperature control, more reliable washing fastness testing

Smart temperature control algorithm achieves accurate and effective test water temperature control.


Humanized design, durable

Multiple safety protection design, the test rotating frame is equipped with an anti-jamming function to protect the equipment.

The heating is achieved by solid state relay controlled electric, bringing more stable temperature and longer service life.

The water tank is made of SUS304 material, also durable. In a word, the WashTrue Washing Color Fastness Tester is reliable.


Application of WashTrue Washing Fastness Tester

Washing Color Fastness Testing is a necessary part of textile color fastness testing. So a washing fastness tester is indispensable. We can evaluate the washing color fastness of the textile quickly by using WashTrue Launder-Ometer.

The WashTrue Washing Color Fastness Tester complies with a wide range of color fastness standards. Besides, the operator can choose between AATCC, ISO, and other test methods. The screen will display the corresponding parameters.

The Test Principle of Colour Fastness to Washing

Textile specimens sewn together with one or two pieces of standard lining fabric are placed in a stainless steel cup mixed with steel balls, soap or soap, and an anhydrous sodium carbonate mixture. Mechanical stirring is carried out at the specified time and temperature by the rotation of a stainless steel cup. When the colorfastness test is over, the sample will be washed and dried. Take the original sample as a reference sample, and evaluate the discoloration of the specimen and the staining of the lining fabric with gray sample cards or instruments. So we can also make perspiration test in textile.

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

1 Set the working temp and working time as the standard requirement.

2 Add the detergent solution and steel balls to the cylinder as per standard requirements.

3 Place an equal number of washpots on each side of the shaft. Start the motor rotation and run for at least 2 min to preheat.

4 After preheating, put the ready samples into the washpots sequential and clamp the lid. Start the machine and run at 40 rpm for a certain amount of time.

5 After the machine stops running, the sample should be washed with distilled water or ionic water, the excess moisture is extracted by centrifuge, and the sample is dried by a possible method.

6 Evaluate the sample according to the standard sample.

As a professional manufacturer of washing fastness testers, we test every washing fastness tester according to the test standard to ensure the normal operation of the instrument. If you want to know the price of the washing color fastness tester, please contact us.


1 Be careful about dealing with all chemicals.

2 Test result rating must be completed in a standard light box.

3 Test solutions should be prepared and used at present according to the need.

4 There should be safety rain shower facilities prepared nearby for emergency use.

5 A rapid drainage system should be installed and equipped with a sewage treatment tank.

6 It is important to follow laboratory practices and wear protective eyewear in the laboratory.

7 When operating the instrument, we should refer to the safety instructions of the instrument manufacturer.

8 The reference detergent which is specified in AATCC 1993 standard can be allergenic. Thus we need to prevent them from touching eyes and skin.

    Q: What is washing fastness?

    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.
