3. Terminology
3.1 colorfastness, n.—the resistance of a material to change in any of its color characteristics, to transfer of its colorant(s) to adjacent materials or both, as a result of the exposure of the material to any environment that might be encountered during the processing, testing, storage or use of the material.
3.2 laundering, n.—of textile ,maericils, a process intended to remove soils andlor stains by treatment (washing) with an aqueous detergent solution and normally including subsequent rinsing, extracting and drying.
4. Safety Precautions
NOTE: These safety precautions are for information purposes only. The precautions are ancillary to the testing procedures and are not intended to be all inclusive. It is the user’s responsibility to use safe and proper techniques in handling materials in the test method. Manufacturers MUST be consulted for specific details such as material safety data sheets and other manufacturer’s recommendations. All OSHA standards and rules must also be consulted and followed.
4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas.
4.2 All chemicals should be handled with care.
4.3 The 1993 AATCC Standard Reference Detergent (with and without optical brighteners) and the 2003 AATCC Standard Reference Liquid Detergent (with and without optical brighteners) may cause irritation. Care should he taken to prevent exposure to skin and eyes.
4.4 An eyewash/safety shower should be located nearby for emergency use.
4.5 Manufacturer’s safety recommendations should be followed when operating laboratory testing equipment.
8.2.2 The color transferred to the multi- fiber test fabric or bleached cotton test fabric square of 6.4.1 can be quantitatively determined by measuring the color difference between a piece of the original material and the stained material. Multifiber test fabrics (15 mm 10.6 in.]) have filling bands of sufficient width to be within the aperture diameter capability of many colorimeters and spectrophotometers (see AATCC Evaluation Procedure 6. Instrumental Color Measurement and 12.14).
9. Interpretation of Results
9.1 Results from these tests are intended to approximate the color change effects (see 1.1) of five typical home launderings. These are accelerated tests, and in obtaining the required degree of acceleration some of the conditions, such as tempcrat tire, were purposely exaggerated. The tests have remained largely the same over many years while laundry detergents, washers and dryers, laundry practices and fabrics have changed (see AATCC monograph “Standardization of Ho,ne Laundry Test conditions, “ elsewhere in this T1CHNICAL MANUAL).
Consequently. caution in interpreting test results is advisable.
9.2 Test No. IA—This test is for evaluating the colorfastness of textiles that are expected to withstand repeated hand laundering at low temperature. Specimens subjected to this test should show color change similar to that produced by five typical careful hand launderings at a temperature of 40 ± 3°C (105 ± 5°F).
9.3 Test No. I B—This test is for evaluating the colorfastness of textiles that are expected to withstand repeated hand laundering at cool temperatures. Specimens subjected to this test should show color change similar to that produced by five typical careful hand launderings at a temperature of 27 ± 3°C (80 ± 5°F).
9.4 Test No. 2A—This test is for evaluating the colorfastness to washing of textiles that are expected to withstand repeated low temperature machine laundering in the home. Specimens subjected to this test should show color change similar to that produced by live home machine launderings at medium or warm setting in the temperature range of 38 ± 3°C (100 ± 5°F).AATCC 61 pdf download.
