Pantone Color Card Colour Color Chart Formula

AATCC six-color nine-grade color c ard is imported from the United States, divided into 9 grades, also known as AATCC color transfer gray card, used for visual evaluation of color transfer or staining degree, 5 hues (red, yellow, green, blue, purple) , 60 color circle. AATCC assessment method P8.

S tandard: AATCC 15,61/61-2A,132,133,163... or more...

Color fastness refers to the resistance of the color of a textile to various effects during processing and use. The fastness rating is based on the discoloration of the sample and the staining of the undyed backing fabric. Textile color fastness testing is a routine testing item in the intrinsic quality testing of textiles.

The degree of fading of dyed fabrics under the action of external factors (extrusion, friction, washing, rain, exposure, etc.) during use or processing is an important indicator of the fabric. Because the conditions of fabrics in the process of processing and use are very different, the requirements are different.

Therefore, most of the current test methods are simulated tests or comprehensive tests according to the environment and conditions of the action, so the test methods for color fastness are quite extensive.

But looking at the International Standards Organization (ISO), the American Association of Dyers and Chemists (AATCC), Japan (JIS), the United Kingdom (BS) and many other standards, the most commonly used standards are wash resistance, light resistance, friction resistance, sweat resistance, and resistance. Ironing, weather resistance, etc.

Common color fastness tests are:

Color fastness to rubbing, color fastness to light, color fastness to washing, color fastness to sea water, color fastness to dry cleaning, color fastness to heat, migration of dyes in storage, color fastness to acid spot and alkali spot ...

Example: AATCC Test Method 15-2002 Brief Description

This test method is used to determine the perspiration fastness of colored fabrics, and can be used for dyeing, printing and other colored textile fibers, yarns and various fabrics, and can also be used to test dyes on fabrics.

Instruments and Materials

Test Sample

6×6+2cm sample, with a piece of AATCC No.10 standard multi-fiber cloth attached with the same size, sew the multi-fiber cloth and the sample together, if it is necessary to use the undyed original grey cloth, sew the sample Sandwiched between the multifiber attached fabric and the original grey fabric.

test program

1. Put each test sample in a reagent tank of 9cm×2cm, add artificial sweat to a depth of 1.5cm, completely soak the sample for 30+2min, stir occasionally to make it completely wet. For fabrics that are difficult to wet, pass the wetted samples alternately through a paddle,

until the test solution penetrates completely.

2. After 30+2min, make each sample pass through the rolling mill, the long side is advanced. Make sure that each sample is 2.25+0.05 times the initial weight. Some fabrics cannot maintain this weight after passing through the paddle, so use AATCC blotting paper (white) to keep it within the specified pick rate range.

In order to obtain consistent results, the samples cut from a piece of cloth should have the same rolling rate in the same experiment, and the staining grade will not increase due to the increase of the amount of liquid.

3. Put each test sample on a marked PVC board or ordinary glass sheet, and each piece of multi-fiber cloth should be perpendicular to the long side of the glass sheet.

4. Put the test samples between the 21 PVC sheets attached to the sweat resistance test device. Regardless of the number of samples, 21 glass slides should be put into the experimenter, and then two more glass slides are placed on the top as elastic compensation, and a 3.63Kg weight is placed to make the total pressure of the slides 4.54Kg.

Turn the screw to lock the pressure plate. The perspiration test device was placed vertically in the oven.

5. Put the fixed sample into the oven and bake at 38+1℃ (100+2F) for 6 hours+5 minutes. Check the oven temperature regularly to ensure that the entire experiment has been kept within the specified temperature range.

6. After 6 hours + 5 minutes, take the sample out of the oven, and place the sample and the attached multi-fiber cloth to dry separately, in a treated environment) 21+1℃, 65+5%RH) to dry. Leave it overnight.
