Abstract
We have examined a screening method for detecting formaldehyde emitted from textile products using a developed formaldehyde-sensing element. We propose two methods. With one method, we measure the amount of formaldehyde emitted from undamaged clothes that had been placed in a package with the developed sensor element. With the other hand, we measure the amount of formaldehyde emitted from clothes that had been cut up and placed in a container with the developed sensor element. We compared the results obtained using these two methods with results obtained using the JIS method (L1041). We found that the determination coefficients for the L1041 method and the two methods were 0.96 and 0.77, respectively, indicating good agreement. We also found that we could carry out a temperature correction of the absorbance values obtained with the two methods. The first method, where we are able to use undamaged clothes without the need to cut them up, would be an effective screening method, because it requires no special procedure, and we can easily estimate the amount of formaldehyde emitted from the clothes simply by placing the sensor element in the package for 1 hour.
