Abstract

Purpose: The aim of this study is to conduct a survey of dimethylformamide(DMF) content in polyurethane(PU)-based consumer products and provide the information for the PU manufacturer and company to prepare a countermeasure for improving the quality competitiveness. Methods: This study selected PU-based consumer products(toddler shoes, children's bag, children's play mat, safety gloves), which is closely used in everyday life, and analyzed the residual DMF content in the consumer products. Results: In this study, it was confirmed that the average DMF content of toddler shoes, children's bag, children's play mat and safety gloves are 38 ppm, 119 ppm, 396 ppm and 826 ppm, respectively. In addition, most of the samples were found to meet the internationally accepted standard of 1,000 ppm and the DMF contents were reduced from at least 63 % to 85 % with a single washing process. Conclusion: The domestic PU manufacturers should seek ways to reduce the DMF through their production facility applications and introducing new materials such as water-soluble PU, and preparing the process development for their quality competitiveness.
