AATCC 107-2002 Colorfastness to Water.
1. Purpose and Scope
1.1 This test method is designed to measure the 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. Principle
2.1 The specimen, backed by multifiber test fabric, is immersed in water un- der specified conditions of temperature and time, and then placed between glass or plastic plates under specified condi- tions of pressure, temperature and time. The change in color of the specimen and the staining of the attached multifiber test fabric are observed.
3. Terminology
3.1 colorfastness, n.—the resistance of a material to change in any of its color characteristics, to transfer of its color- ant(s) to adjacent materials or both, as a result of the exposure of the material to any environment that might be encoun- tered during the processing, testing, storage or use of the material.
4. Safety Precautions NOTE: These safety precautions are for information purposes only. The precautions are ancillary to the testing proce- dures and are not intended to be all inclu- sive. 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 must also be consulted and followed.
4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas.
4.2 Manufacturer’s safety recommendations should be followed when operat- ing laboratory testing equipment.
4.3 Observe padder safety. Ensure adequate guard at the nip point. Normal safeguards on pad should not be removed.AATCC 107 pdf download.
