4.44 (9 reviews)

Washing Fastness Tester, to determine color fastness to washing or dry cleaning to ISO, AATCC standards. Washing Fastness Tester complies with AATCC 61, ISO105-C06/C08/C09, etc. Color fastness to washing is directly related to our health.



Washing Fastness Tester, to determine color fastness to washing or dry cleaning to ISO, AATCC standards.

The washing fastness tester uses stainless steel rotor to holds washpots on each of four sides and rotates at a constant 40 rpm (+/-2 rpm). Washpots are preheated in appropriate test solution.

Containers are sealed with either a Neoprene rubber gasket or optional Teflon gasket.

To carry out the tests of AATCC and ISO standard fast, TESTEX redesigned the Washing Fastness Tester, with two baths to offer a maximum combined capacity of 12 and 6 vessels, and the baths have completely separate controls and drive systems, so they can be used as two independent machines for both ISO and AATCC standards. Opening door, test-finished alarm, etc.

Stainless-steel balls and pieces are included.

Single bath combined with both ISO and AATCC washpots in less quantity are offered on request.

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 faded 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, the cloth with poor color fastness will cause other clothes to be stained with color and dye other clothes when washing with other clothes.

The Test Principle of Colour Fastness to Washing

Install stainless steel cups containing samples, detergents and steel beads on the main shaft, heat the water in the box to a fixed temperature. Then start the motor drives the spindle to rotate at a speed of 40 rpm, which causes the samples and steel beads in the cup to rub each other for a certain time in the environment of the washing liquid at a certain temperature. Finally, rinse and dry, grade with the standard sample, and get the test results. Different test methods have the different temperature, alkalinity, bleaching condition, friction condition and sample size, which should be selected according to the test standard and actual conditions.

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 of not fading and changing color. ISO 105C01-C05 provides several test methods for color fastness to washing, covering the range from mild to the 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 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 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 tester, 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 washing color fastness tester, please contact us.

  1. Richard

    Great to have one machine for meeting two standards testing requirements.

  2. Sherrif

    For two major standards testing, ISO and AATCC, this launderometer is enough

  3. James Charles

    I bought this Launderometer to help check the color fastness for a couple of upcoming projects. It more than paid for itself the day I got it.

  4. Cliff Michael

    Although it is a little bit expensive,it is worthwhile.Will come again.

  5. Sabina Bridges

    Perfect washing fastness tester,thanks manufacturer.
