Modification of PET Fabric Using Tetrabutyl Titanate by Hydrothermal Method

The disappearance of photocatalytic properties of titanium dioxide nanoparticles formed on PET fabrics treated in a simultaneous hydrothermal-dyeing process

“…Similar to previous research (Zhang et al, 2011), the immobilization of TiO2 on PET fabric was realized by a hydrothermal method. Five milliliter of tetrabutyl titanate was first added into 50 mL of ethanol solution under vigorous stirring.…”

“…Ti2p XPS spectrum of the TiO2 coated PET fabrics from solely hydrothermal process without dispersion dye, it can be deconvoluted into four distinct sub-peaks. The sub-peaks at 458.66 eV and 464.36 eV are attributed to Ti 4+ 2p3/2 and Ti 4+ 2p1/2 of TiO2 nanoparticle, respectively; The sub-peaks at 460.87 eV and 465.86 eV are ascribed to Ti 3+ 2p3/2 and Ti 3+ 2p1/2 respectively (Pandiyaraj et al, 2014), indicating the binding of Ti atoms of TiO2 nanoparticle with O atoms of PET fabric (Zhang et al, 2011). , The Journal of The Textile Institute, DOI: 10.1080/00405000.2018.1429241 Figure 6.…”

“…In situ growth of TiO2 nanoparticles using TiO2 precursor in hot water (Meng, Feng, Li, & Zhang, 2012), and TiO2 supported PET sheet for photocatalytic oxidation of organic dye in sunlight have been investigated (EL-Mekkawi, Nady, Abdelwahab, Mohamed, & Abdel-Mottaleb, 2016). The Ti02-coated PET fabrics have been prepared via hydrothermal process using tetrabutyl titanate (Zhang, Xu, & Yang, 2011) while their photocatalytic activities have not been investigated. The photocatalytic leroperties of TiO2 nanoparticles on PET fabrics treated in hydrothermal process using titanium sulfate and urea aqueous solutions (Zhang, Zhu, & Sun, 2012) have also been studied, however, the photocatalytic properties of TiO2 nanoparticles on PET fabrics treated in a simultaneous hydrothermal-dyeing process have never been investigated.…”

Simultaneous reactive dyeing and surface modification of polyamide fabric with TiO2 precursor finish using a one-step hydrothermal process

“…44,45 The aim of this study is to develop a hydrothermal&dyeing process to modify and dye PA fabric using titanium sulfate or tetrabutyl titanate precursor in conjunction with C. Unlike the previous studies, 47,48 where tetrabutyl titanate (or titanium sulfate and urea) was solely used in the fabric modifications, the TiO 2 precursor in this study was mixed with the Reactive Blue dye liquor to treat PA fabric under hydrothermal condition. The time duration used for the hydrothermal&dyeing process for the two different TiO 2 precursors were set as 5 and 3 hours respectively based on previous solely hydrothermal experiments 47,48 in order to produce anatase TiO 2 particles. The chemical compositions of the PA fabrics from both of the two schemes were determined by Energy Dispersive X&ray Spectroscope (EDX) attached to the FE&SEM instrument.…”

“…Two TiO 2 precursors, titanium sulfate and tetrabutyl titanate, were used to modify the pretreated PA fabrics respectively. Unlike previous studies, 47,48 where tetrabutyl titanate (or titanium sulfate and urea) was solely used in the fabric modifications, the TiO 2 precursor in this study was mixed with the C.I. Reactive Blue 19 dye liquor to treat PA fabric under hydrothermal conditions.…”
