Application
he Gas Fume Exposure Chamber evaluates the color fastness of textiles when exposed to atmospheric oxides of nitrogen produced from gas combustion. This device simultaneously exposes a textile specimen and a test control fabric to burnt gas fumes until the control fabric changes color to match a standard fading level. The textile’s color change is then compared using a standard gray scale for assessing color change.
The chamber features a testing section, a burning and control section, a rotating sample rack, a standardized gas burner, a test duration timer, and an exhaust port for connection to an extractor system. Temperature settings are digitally controlled through a touch panel and managed automatically via a closed-loop PLC system.
For enhanced safety, the chamber includes an automatic ignition system at the start of testing or if the burner extinguishes mid-test. A gas leakage detection device prevents ignition if a leak is detected, and a top-mounted fan activates to ensure safe operation.
