1. Purpose and scope1.1. This test method is designed to measure resistance to water of dyed,printed,or otherwise colored textile yarns and fabrics.1.2. Distilled water or deionized water is used in this test method because natural (tap) water is variable in composition.

2. Principle2.1. the specimen,backed by multifiber test fabric,is immersed in water under specified conditions of temperature and time ,and then placed between glass or plastic plates under specified conditions of pressure,temperature and time.The change in color of the specimen and the staining of

3. Terminology3.1. colorfastness ,n : the resistance of a material to change in any 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.

4. safety precautionsNOTE: 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 this 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 m

6. Test Solution6.1. freshly boiled dis

7. test specimens7.1. Colored specimens 60*60 mm ±2mm (2.25*2.25in.) backed with multifiber test fabric.

8. Procedure8.1. immerse the test specimen in the test solution at room temperature with occasional agitation to ensure thorough wetting out (approximately 15 min generally required for average fabrics)(see 12.4)8.2. remove the test specimen from the test solution and only pass between squeeze rolls (wringer) to remove excess liquor when the wet weight of the test specimen is more than 3 times its dry weight.whenever possible,the wet weight should be 2.5-3.5times the dry weight.8.3. place the test specimen between glass or plastic plates and insert in the specimen unit of the perspiration tester. Adjust the perspiration t

9. evaluation method for color change9.1 rate the effect on the color of the test specimens by the gray scale for color change(see 12.1).Grade 5__negligible or no change as shown in gray scale step 5.Grade 4.5__change in color equivalent to gray scale step 4-5.Grade 4__change in color equivalent to gray scale step 4.Grade 3.5__change in color equivalent to gray scale step 3-4.Grade 3__change in color equivalent to gray scale step 3.Grade 2.5__change in color equivalent to gray scale step 2-3.Grade 2__change in color equiv

10. evaluation method for staining.10.1. rate the staining of the multifiber test fabric (see 12.5)by the AATCC chromatic transference scale or the gray scale for staining. Report which classification scale is used(see 12.6).Grade 5__negligible or no color transfer.Grade 4.5__color transfer equivalent to step 4-5 on the gray scale for staining or row 4.5 on the 9-step AATCC chromatic transference scale.Grade 4__color transfer equivalent to step 4 on the gray scale for staining or row 4 on the 9-step AATCC chromatic transference scale.Grade 3.5__color transfer equivalent to step 3-4 on the gray scale for staining or row 3.5 on the 9-step AATCC chro

AATCC perspiration tester: put all 21 glass or plastic plates into the unit regardless of the number of specimens. After the final glass or plastic plate is put in position on top, set the dual plates with compensating s
