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.
