Overview
The CSI-238BB AATCC Electric Friction Color Fastness Tester is a test instrument designated by the American Society of Spinning & Weaving Chemists and the Association of Printers and Dyeers to evaluate the ability of fabrics to transfer Color from the material surface to Miscellaneous materials under dry and wet friction conditions. In addition to color transfer testing, the instrument can also be used for abrasion, dry/wet friction, flexural, chalking, dry cleaning, grinding and other tests to ensure that the sample conditions are controllable and repeatability through standard pressure and motion methods.
Features
1. Meet many international standards such as the American Association of Spinning & weaving Chemists (AATCC).
2. Available in both dry and wet friction test modes.
3. A variety of tests can be carried out, including Color transfer, abrasion, flexibility, chalking, dry cleaning and grinding.
4. Standard pressure and movement methods are used to ensure controlled test conditions and repeatability of results.
5. The linear reciprocating motion and friction velocity parameters are accurate, and the applied pressure is stable.
Principle
The instrument simulates the friction process by driving the friction head to reciprocate in a straight line on the surface of the specimen. At a set pressure (e.g. 9N +/- 10%) and motion parameters (104 +/- 3mm, speed 1 cycle/sec), the specimen is brought into contact with the friction material to evaluate Color transfer or changes in Miscellaneous physical performance.
Applications
Spinning & weaving colour fastness testing, printing and dyeing industry quality control, Fabric Abrasion Resistance Evaluation, Material surface performance research
Standards
AATCC 8、AATCC 165、ASTM F1329、EN ISO 105-X12、ISO 105-D02、JIS K6328、JIS L0849、JIS L1084、GB/T 3920
Steps
1. Prepare the specimen and friction cloth according to test standards (e.g. AATCC 8).
2. Fix the specimen on the instrument platform.
3. Install the friction head according to the test requirements (dry friction or wet friction) and apply the standard pressure (9N +/- 10%).
4. Set instrument parameters, such as stroke (104 +/- 3mm) and friction velocity (1 cycle/sec).
5. Start the instrument and perform a specified number of friction cycles.
6. After the test, remove the specimen and friction cloth and evaluate the degree of Color Transfer or Miscellaneous performance change according to the standard.
Notice
• Make sure the instrument is placed horizontally and firmly before use.
• Choose and install the friction head and pressure correctly according to different test standards.
• During the wet friction test, ensure that the moisture content of the friction cloth meets the standards.
• Regularly calibrate the instrument to ensure that the applied pressure and motion parameters are accurate.
• After the test is completed, clean the instrument friction head and platform to avoid residues affecting subsequent test results.
• Follow relevant safety regulations when operating to avoid mechanical injuries.
