Color Fastness to Washing SW-8A/12A

Color Fastness to Washing SW-8A/12A  

The sample is tested under suitable temperature, washing liquid, bleaching and friction. The color changes of samples can be obtained in a short time. This friction is produced by the impact of samples and containers, low bath ratio solutions and steel balls.

The main factors affecting the test results, in the fading effect method, Its importance is in turn. : temperature, color with white cloth, fluid volume, stainless steel ball, time and the order of the stainless steel ball interaction.

The influence of temperature was the most, and the factors that were in the color white cloth had little effect. The importance in influencing the stained white cloth is the interaction of color white cloth, temperature, sodium carbonate, liquid amount, time, and stainless steel ball.

Among them, the color white cloth has the greatest influence, the temperature influence is also very big, the time and the stainless steel ball these two factors have little influence. For this reason, different test temperatures should be selected for samples of different fibers.

Follows are Color Fastness to Washing specification :

• Touch screen, easy to operate;
• Low water level protection, the heating is not accessible if do not reach minimum water level;
• Relative standards have been built in the program, select the corresponding standard to proceed the running directly;
• Custom standards, define the standard by oneself, e.g. temperature, time;
• Fitted with over temperature protection device to shut down the unit in case of overheating;
• Stainless steel construction of water bath chamber, test chamber and container;
• Alarm automatically when the test is over;
• SW-8A/8AB/12A/12B/12AB: One working chamber, 8pcs/12pcs 550ml containers or 6pcs 1,200ml containers can be used simultaneously;
• SW-12M: One working chamber and one pre-heating chamber, 12pcs 550ml containers or 6pcs 1,200ml containers can be used simultaneously. The other type of containers (1,200ml or 550ml) can be heated ahead, the testing time will be decreased;
• SW-24A: Two working chambers, 24pcs 550ml containers or 12pcs 1,200ml containers can be used simultaneously.
