To reduce the indoor formaldehyde pollution, wool fabrics with natural affinity to formaldehyde were modified by dopamine (DOPA) to enhance their attraction to formaldehyde.After testing for 120min, the original wool fabric could reduce around 20.1% of the initial formaldehyde, while the modified fabrics displayed substantial increments in formaldehyde removal efficiency.The fabric treated for 4h has a raised efficiency about 34.0%, and a linearly increasing trend was kept after 120min.The abrasion and washing processes could reduce the formaldehyde removal efficiencies of fabrics, and the effect was more obvious for the fabrics modified for a longer time, but the maximum reduction was only 5.3%, which indicated sufficient durability.The results proved the potential of the modified wool fabrics for the development of indoor formaldehyde removal products.
