Study and analysis of fluorescent whitening agents in hotel textiles
The 300 different kinds of hotel textile samples from different grade hotels were purchased,the types,contents and sources of FWAs in these samples were detected by high performance liquid chromatography,and 19 fluorescent whitening agents(FWAs)commonly used in the textile field were used as the research basis.The results showed that 94％of the samples of hotel textiles contained FWAs,and the top 5 most frequently used were FWA71,FWA85,FWA351,FWA113 and FWA134,and the highest average detected content was 800.82mg/kg;the detection rate of FWAs in middle and low-end hotels is higher than that in high-end hotels,and the detection rate of FWAs in bath towel series is higher than that in catering series and bedding series.In addition,the FWAs in hotel textiles are derived from detergents in the post-finishing and cleaning processes of the production process.
