| description | Titanium dioxide (TiO2 ) has an extraordinary photocatalytic activity and it effectively provides
self-cleaning properties for cotton products. With the presence of succinic acid, it helps the
adherence of the TiO2 nanoparticles on cotton surfaces. However, the ability of succinic acid
to keep the TiO2 adhered on cotton after washing is not yet fully understood. Therefore, this
study aimed to investigate the effects of washing cycles on nano-TiO2 coated cotton yarn with
the aid of succinic acid on the morphological structures and self-cleaning properties. In this
study, the nano-TiO2 was synthesized using a hydrothermal method. The cotton yarn was
coated with succinic acid and was later dipped in a nano-TiO2 nanoparticles suspension. The
nano-TiO2 coated yarn samples then underwent the 5th, 10th, 15th, and 20th wash cycles
and were tested for morphological structures and self-cleaning. The self-cleaning properties
of the nano-TiO2 coated yarn were determined using the depth of colour stain. The depth of
the colour stain was presented as K/S value, where K and S are corresponded to the absorption
and scattering coefficients of the stained fabric, respectively. From the analysis, our
synthesized nano-TiO2 had a size of 20–50 nm range with a band gap of 3.06 eV. After
coating, the nano-TiO2 coated cotton yarn changed in its morphological structure at 5th, 10th,
15th , and 20th wash cycles, respectively. At the 20th wash cycle, the weight (%) of the Ti
element continued to decrease up to 4.45%, reducing the photocatalytic activity with the K/S
value close to the stained yarn, which was about 0.4. The 5th wash cycle maintained a good
photocatalytic activity with the K/S value of 0.06 near to the K/S value of the unstained cotton
yarn. The presence of succinic acid in the nano-TiO2 coated cotton yarn provided good selfcleaning properties up to the 15th wash cycle. By undertaking this study, an enhanced cotton
property has been developed that will benefit the textile and clothing industry. This nano-TiO2
coated cotton the has potential to be used for daily apparel and sportwear. |
