The 722s-type visible spectrophotometer,UV-1801 ultraviolet spectrophotometer,and ONIBA ultraviolet/visible spectrophotometer were analyzed for formaldehyde testing in textiles.The performance indicators of the three instruments were evaluated,and the detection limits,lower limits of measurement,and upper limits of measurement were compared.A non-destructive method for formaldehyde testing in textiles was proposed and was compared with the existing GB/T 2912.1-2009"Textiles-Determination of Formaldehyde-Part 1:Formaldehyde in Water-Extraction Method"(a destructive method).The determination of non-destructive textile formaldehyde concentration at different times and temperatures was conducted to establish optimal testing conditions and to identify an economical spectrophotometer,providing a reference for the selection of spectrophotometers in textile formaldehyde testing.
