摘要

In the past, wrinkle-resistant finishes on cotton fabrics involved the application of melamine–formaldehyde- or urea–nformaldehyde-based resins with many more recent agents being based on dimethyloldihydroxyethyleneurea (DMDHEU).nThis study reports that the DMDHEU–TiO2 combination can enhance the wrinkle-resistance of cotton fabrics. Thenaddition of TiO2 or nano-TiO2 in the treatment can also act as a multi-functional finishing agent to improve the UVnprotection property. Moreover, it was found that addition of TiO2 or nano-TiO2 could slightly increase the tearingnstrength of test specimens to compensate for the drawbacks of DMDHEU. However, the addition of metal oxide did notnsignificantly improve the tensile strength of specimens. In addition, it was found that while DMDHEU-treated cottonnspecimens contained small quantities of free formaldehyde, these levels are reduced when nano-TiO2 is added to thentreatment.
