Coating Effect on Magnetic Properties of Amorphous Ribbons
In this research, the electrodeposition technique was employed to prepare fine-grained nickel, iron and iron-cobalt coatings with 1 μm thicknesses on the substrate of the amorphous ribbons. The coating effect on magnetic properties was examined at room temperature using an ADE Magnetics EV9 vibrating sample magnetometer with maximum magnetic field strength of 1750 kA/m. It is found that Ni, Fe, and Fe-Co coated amorphous ribbons show 0.60, 0.71, and 1.01 T saturation magnetization, respectively, while uncoated ribbon has 1.55 T
Yellowing tendency of ozonated cotton fabric and ways to prevent this undesirable side effect
WOS: 000271012500011This paper provides a general framework for studying the yellowing tendency of ozonated cotton fabric. Yellowing tendency of ozonated cotton fabric and ways to prevent this situation was examined extensively. For this purpose, five different treatments (hot/cold rinsing, washing, reductive washing, catalase treatment) were performed after ozonation. It was found that performing any kind of treatment was significantly important for preventing yellowing of ozonated cotton fabric during storage
USAGE OF LACCASE IN DENIM WASHING
WOS: 000344418300010Denim is a twill fabric in which only the warp yarn is dyed with indigo dye. Denim fabrics are very popular in this century because they have high stability form and ensure different opportunities for novel esthetic and fashional effects and very comfortable. This can be ensured with different washing techniques generally consisting hazardous chemicals. Today because of environmental aspects and conscious, enzymes became an alternative to conventional processes in textile finishing. Among the enzymes used in textile treatment processes laccases are relatively new and usability is limited. In this study, it was aimed to investigate the use of laccase in denim washing. It was observed that especially enzymatic treatment duration has of great importance for the higher L* values of the denim garments. But with the increase in duration the back-staining was come out evidently. pH and Enzyme concentration has also effects on the obtained results but they were limitedTUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [107M414]We thank Busra Konca, Deniz Onar ve Vedat Esetekin for experimental aid and this study is supported by TUBITAK (Project No: 107M414)
An investigation in the use of ozone gas in the bleaching of cotton fabrics
WOS: 000250445700003Ozone, composed of three atoms of oxygen, can be used to oxidize many inorganic and organic impurities. Because of its high oxidizing capacity, the opportunities and parameters of ozone gas use in bleaching of cotton fabrics were researched in this study. It was found that in a very short time cotton fabrics can be bleached if the water content of cotton-woven fabric was 60% and the pH of the water impregnated was 7. Moreover, ozonation at room temperature was shown to be more efficient than ozonation at high to medium temperatures
