Abstract:

Polyvinylidene fluoride (PVDF) resin and nano-TiO2 were used to treat polyester fabric as raw materials to prepare the durable textiles with the photo-catalytic self-cleaning properties. The self-cleaning properties of the coated fabric, the abrasion resistance of the self-cleaning coating and the aging resistance of the self-cleaning coating were tested by digital image colorimetric system, scanning electron microscopy and energy dispersive spectrometer. Result reveal that with the increase of the amount of TiO2, the self-cleaning effect of coated fabric is enhanced, but the rheological property of the coating pulp is deteriorated, the integrity of the self-cleaning coat is reduced, the bonding effect of PVDF to TiO2 is reduced, the abrasion resistance effect and aging resistance of self-cleaning coating are deteriorated. When the adosage of TiO2 is 33.3%, the rheological property of the coating pulp is better, the self-cleaning coat is even, the self-cleaning properties, the aging resistance and the  abrasion resistance of the self-cleaning are also better.

Key words: photo-catalytic, self-cleaning, coated fabric, polyvinylidene fluoride, aging resistance
