Here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (TEA) and zinc acetate. The ZnO nano particles (NPs) were formed and stabilized on the fabric surface by amine compound at 130 °C for 1 h. The synthesis of nano ZnO particles on the polyester fabric were confirmed by X-ray diffraction (XRD) pattern...

a feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. the nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy/energy dispersive x-ray spectrometry (sem/eds) and x-ray d...

Abstract Two polyester-lignite composite coated urea slow-release fertilizers (SRFs; Poly3 and Poly5) were developed their physicochemical properties studied. Both these SRFs significantly (p < 0.05) extended the release compared to uncoated urea; Poly5 by 117 172 h, respectively. The characteristics of further enhanced linseed oil application (Poly5-linseed). SEM images demonstrated coating...

The aim of this study is to apply and compare statistical regression and an evolutionary fuzzy system to model color yield in the polyester high temperature (HT) dyeing as a function of disperse dyes concentration, temperature and time. The predictive power of the obtained models was evaluated by means of MSE value. It seems that for modeling cases such as the one considered in this study, the ...

The effect of twi st on the performance of polyethylene naphthal ate, dimensionally stable polyester and high-tenacity polyester cord yarns has been studied. h is observed that the twi st has a very important effect on the tensile properties, creep properties and fracture mechani sm. An increase in the twi st leve l increases breaking elongation and creep rate but decreases break ing strength. ...

The discovery of polyurethane [PU] dates back to the year 1937 by Otto Bayer and his coworkers at the laboratories of I.G. Farben in Leverkusen, Germany. The initial works focussed on PU products obtained from aliphatic diisocyanate and diamine forming polyurea, till the interesting properties of PU obtained from an aliphatic diisocyanate and glycol, were realized. Polyisocyanates became commer...

Binary and ternary composites were synthesized using a polyester matrix reinforced by two types of carbon inclusions, namely, nanotubes (CNT) graphite (Gt) (CNT/Gt/Polyester). Thermal analyses performed, thermogravimetry differential scanning calorimetry, which allowed us to observe significant changes in glass transition temperatures degradation the composites. Dielectric measurements performe...
