Pet Film

In this study the vapour phase surface graft polymerization of acrylonitrile (AN) onto poly(ethylene terephthalate) (PET) film was conducted with benzoyl peroxide (BPO) as an initiator. Effects of reaction time and quantity of BPO on the polymerization were investigated. With the prolongation of reaction time, the graft polymerization took place rapidly at first, then slowed down, and leveled off. With the increase of BPO, the graft yield increased, then remained unchanged, and lastly began to decrease. The surface topography structure of the grafted PET film was observed by SEM. Grafted PET film was characterised by FTIR spectra, SEM photographs and contact angle measurement.

Multifilament Yarns

Recycled poly(ethylene terephthalate) (RPET) multifilament yarns are used in carpet manufacturing as a way to reduce plastic waste. The conventional RPET carpet is however susceptible to bacterial accumulation. As a result, this research experimentally doped RPET with nano-structure titanium dioxide (nano-TiO2) to produce RPET/nano-TiO2 bicomponent multifilament yarns with antibacterial property. The experimental multifilament yarn structure consisted of two parts: neat RPET core and RPET/nano-TiO2 shell. The nano-TiO2 content in the shell was varied between 1 and 3 wt% and the core/shell (C/S) ratios between 90/10, 70/30, and 50/50 w/w. The effects of C/S ratio and nano-TiO2 content on the mechanical and antibacterial properties of bicomponent multifilament yarns were determined. The experimental results indicated that the C/S ratio had no effect on the tenacity and elongation at break. Meanwhile, the tenacity and elongation at break of bicomponent fibers increased with nano-TiO2 content in the shell. The TiO2-doped RPET bicomponent yarns effectively inhibited the growth of Escherichia coli and Staphylococcus aureus. The 90/10 bicomponent multifilament fiber with 3 wt% TiO2 achieved the highest antibacterial activity. The very high antibacterial activity was attributable to greater deposition of nano-TiO2 particles near and on the shell surface.
