Bahareh Moazzenchi,Majid Montazer 한국섬유공학회 2020 Fibers and polymers Vol.21 No.3
Here, copper nanoparticles were in situ synthesized on polyester fabric using cost effective chemicals, withoutstabilizing and sensitizing agents through a simple click electroless plating method to attain the electrical conductivefabric. Central composite design based on response surface methodology was applied to study the influence of copper saltprecursor and reducing agent concentration on the electrical resistivity. The best sample with the lowest electricalresistivity was chosen and analyzed and then similar processing conditions were applied under ultrasonic conditionbesides final fabrics were subjected to the diverse characterizations. Findings suggested the potentiality of the one-potsonoplating method for fabrication of copper nanoparticles on polyester fabric. The successful synthesis of coppernanoparticles on the polyester fabric was verified by scanning electron microscopy (SEM) images and X-ray diffraction(XRD) patterns. A remarkable low electrical resistivity of 0.5 Ω·cm obtained on the sonotreated samples produced withincorporation of copper nanoparticles. Further, good results indicated on the mechanical properties of the copper treatedfabrics. All of the observations perceive the great potential applications of the product in electrical, medical and smarttextiles industries.

Ultraviolet (UV) radiation is harmful for humans. Some textiles can protect humans against UV radiation. Ordinary fabrics have low ultraviolet protection values and can be modified by some finishing treatments. In this researchwork, madder and weld as natural dyes were used to dye wool fabric in order to increase UV protection. Two methods wereused to modify natural dyeing of the wool fabric. In the first one, CuSO4 and FeSO4 were used as mordant for natural dyeing. In the second method, which is novel, plasma sputtering of wool fabrics by Cu and Fe in order to improve the UPF value andthe affinity of wool fabric towards natural dyes were used and results were compared. The results show that, both natural dyeand mordant treatment are effective in improving the UV protection properties of wool fabrics. On the other hand, plasmasputtering as an eco-friendly and dry method play very important role for improving the UPF value of the fabrics.

Effect of Using Cold Plasma on Dyeing Properties of Polypropylene Fabrics
Shahidi, S.,Ghoranneviss, M.,Moazzenchi, B.,Rashidi, A.,Dorranian, D. The Korean Fiber Society 2007 Fibers and polymers Vol.8 No.1
The low temperature plasma(LTP) technique is used widely to modify polymer and textile materials. This paper describes the development of a plasma system for textile treatment. Polypropylene(PP) has a very low value of the surface free energy(approximately 20-25 $mJ/m^2$). Due to low surface energy, Polypropylene has very weak hydrophilic properties. By controlling the plasma variables, such as the nature of gas, the discharge power, the pressure and the exposure time, a great variety of surface effects can be generated. In this paper, we report the effect of cold plasma of $O_2\;and\;N_2$ gases at various time of exposure on the dyeing and physical properties of PP fabrics. The results show a significant increase in the color depth upon dyeing after treating PP fabrics with low temperature plasma of $O_2\;and\;N_2$. For comparing the amount of fabrics dye exhaustion, we have used reflective spectrophotometer. The morphology of the modified surfaces has also been investigated using scanning electron microscopy(SEM). And also FTIR was used to examine the functional groups of the corresponding samples.
