Photodegradation of a disperse dye on Polyester Fiber and in solution
Dyes and Pigments, 1996Co-Authors: Nobuyuki Katsuda, Takashi Omura, Katsumasa Otake, Satoshi Yabushita, Toru TakagishiAbstract:The photodegradation behavior of dyes on Fibers such as nylon, cotton Fibers, and in particular, Polyester, and in a solution has been investigated. The undyed and dyed Fibers were irradiated with monochromatic light of various wavelengths. The light source was separated into 20 distinct wavelengths and the photodegradation behavior at each wavelength was examined. It was found that the most effective wavelength for the photodegradation of a disperse dye on Polyester Fiber was near 320 nm. The wavelength also affected the photodegradation of the Fiber itself. Similar phenomena were observed for nylon Fiber: light near 370 nm influenced significantly both the dye on the Fiber and the Fiber itself. With cotton, light at 260 nm was significant. To clarify these results, photodegradation of the dye in ethyl acetate containing dissolved Polyester was also carried out. The same phenomena as those observed on the Fiber were shown to be operative. Copyright © 1996 Elsevier Science Ltd.

Stabilizing Geotechnical Properties of Loess Soil by Mixing Recycled Polyester Fiber and Nano-SiO_2
Geotechnical and Geological Engineering, 2019Co-Authors: Jalil Mohammad Sarli, Farhad Hadadi, Rahmat-allah BagheriAbstract:The present study investigated the effect of recycled Polyester Fiber in combination with nano-SiO_2 as a new stabilizer for improving the geotechnical properties of the loess soil. In addition, it intended to evaluate the effect of adding recycled Polyester Fiber and nano-SiO_2 on engineering properties of the soil, especially the maximum dry density and shear strength using silty loess with low liquid limit. To this end, three different combinations of Fiber and nano-SiO_2 ratios were used ranging between 2 and 6% in proportions of 33% and 50% for the total dry weight of the soil. Furthermore, three different combinations of Fiber-soil ratios were employed which ranged between 0.5 and 1.5% for the total dry weight of the soil, as well as three different combinations of nano-SiO_2 ratios ranging between 2 and 6% for the total dry weight of the soil. The results from the compaction test indicated that the maximum dry density of the stabilized loess decreased while the optimum water content increased by adding recycled Polyester and nano-SiO_2. Based on the results of the direct shear test, the shear strength improved by increasing the contents of the recycled Polyester Fiber and nano-SiO_2 in the soil mixture. Thus, the addition of recycled Polyester and nano-SiO_2 improved the strength properties of the loess soil. In order to obtain the maximum increase in shear strength, the optimum content of the recycled Polyester Fiber and nano-SiO_2 was 4% of loess soil dry weight in proportions of 33% and 50% in the mixture.
