Abstract：Printing and dyeing of textile industry is one of the major industries that emit VOCs (volatile organic gas). For the non-organized emissions of VOCs, our country's current relevant standards adopted to the enterprise boundary detection, but there is little research on the detection of single process. It is just this part of the exhaust gas that seriously affect the health of the workers and the surrounding residents. In order to monitor unorganized VOCs emissions on different section of two typical printing and dyeing enterprises, I used Dual-detector gas analyzer and portable infrared imaging devices. Compared with the existing standard limits, the non-organized VOCs concentration of ordinary printing section is about twice that of standard limits, while the concentration in the digital printing section is only a third of standard limits. So that digital printing is a cleaner and more environmentally friendly technology. The concentration of the partial leak exceeds the standard limits by as much as more than fifty times.
