1、AATCC Test Method 15-2009 Colorfastness to Perspiration Developed in 1949 by AATCC Commit tee RR52; jurisdiction translerred to AATCC Committee RA23 in 2006; re vised 1952, 1957, 1960, 1962, 1972, 1973, 1975, 1976, 1997, 2009; reaf firmed 1967, 1979, 1985, 1989, 2007; editorially revised 1961, 1967,

Purpose and Scope l.lThis test method is used to deter mine the fastness of colored textiles to the effects of acid perspiration. It is appli cable to dyed, printed or other,vis
3、e col ored textile fibers, yarns and fabrics ofatl kinds and to the testing of dyestuffs as applied to textiles. 1.2 Work by Comnllttce RA52 showed this test will correlate with limited field studies. Prior to this there were acid and alkaline tests; however, as a result of these studies the alkalin
4、e test was elimi nated (see 13.1). 2. Principle 2.1 A specimen of colored textile in contact with other fiber materials (for color transfer) is wet out in simulated acid perspiration solution, subjected to a fixed mechanical pressure and allowed to dry slowly at a slightly elevated tempera ture. Aft
5、er conditioning, the specimen is evaluated for color change and the other fiber materials are evaluated for color transfer. turers MUST be consulted for specific details such as material safety data sheets and other manufacturers recommenda tions. All OSHA standards and lades must also be consulted
6、and followed. 4.1 Follow good laboratory practices. Wear safety glasses in all laboratory areas. 4.2 All chemicals should be handled with care. 4.3Observe padder safety. Normal safe guards on pad should not be re moved. Ensure adequate guard at the nip point. A foot operated kick off is recom mended
7、 for a motorized padder. 5. Apparatus, Materials and Reagents (see 13.2) 5.1 Perspiration tester (plastic or glass plates are available with tile equipmen0 (see Figs. 1 and 2). 5.2 Drying oven-convection. 5.3 Balance with a weighing accuracy of 0.001 g. 5.4 Multifiber test fabrle (8 mm 0.33 in. fill
8、ing bands) containing acetate, cot ton, nylon, silk, viscose rayon and wool shall be used for specimens containing silk. Multifiber test fabric (8 mm 0.33 in. filliag bands) containing acetate, cot ton, nylon, polyester, acrylic and wool shall be used with specimens with no silk present (see 13.3).

Preparation ol Reagent 6.1 Prepare the acid per
10、spiration solu tion by filling a 1 L volumetric flask half fidl of distilled water. Add the following chemicals and mix to be sure that all chemicals are thoroughly dissolved: l 0 0.01 g sodium chloride (NaCI) 1 0.01 g lactic acid, USP 85% 1 - 0.0l g sodium phosphate, dibasic, anhydrous (Na2HPO4) 0.
11、25 :t: 0.001 g g-histidine monohydro chloride (C6HgN302.HCI.H20) Fill file volumetric flask with distilled water to the 1 L mark. 6.2 Test the pH of tile solution with a pH meter. If it is not 4.3 a_ 0.2 discard it and prepare a new one, making sure all ingredients are weighed accurately. The use of
12、 pH test paper is not recommended for this purpose because of its lack of accuracy. 6.3 Do not use perspiration solution that is more than three days old (see 13.5). 3. Terminology 3. l colorfastness, n.he resistance of a material to change in any of its color characteristics, to transfer of its col

Safety Precautions NOTE: These safe
14、ty precautions are for information purposes only. The pre cautions are ancillary to the testing proce dures and are not intended to be all inclu sive. It is the users responsibility to use safe and proper techniques in handling materials in this test method. ManufacFig. 1-Horizontal perspiration tes

The following observations and cor rective actions are extremely important to avoid incorrect test results. 7.2 Use an in-house perspiration fabric with a
16、mid-range visual grade on the most heavily stained stripe of the multift ber cloth as a calibration specimen and conduct a perspiration test using three specimens. Verification checks should be performed periodically as well as each time a new lot ofmultiftber or uadyed ad jacent fabric is used. 7.2.1 Non-uniform color transfer may be due to improper wet-out procedures or may be a result of uneven pressure on the specimens due to warped plates in the tester. Check tile wet-out pro
