摘要

Wet chemical processing of textiles is important to remove the impurities from the fibre surface and to make accessible for dyeing and value added finishing, besides improvement in aesthetic and functional value. However, the process is water, energy,and chemical intensive due to the liquid based multi-step operations. In this study, cotton textile was plasma treated in an indigenously developed atmospheric pressure plasma reactor in presence of Helium (He), helium-oxygen (He-02), helium-fluorocarbon (He-FC) gases for improvement in hydrophilic and hydrophobic functionalities without using water as a processing medium. Optical emission spectrum (OES) showed the fragmentation of fluorocarbon with atomic lines of F at 429 nm, 357 nm, 341 nm, 325 nm,and -CF2 at 318 nm. After the plasma treatment, hydrophilic cotton turned into highly hydrophobic one. As a result of this, a water droplet of 37u.l did not get absorbed by the fabric even after 60 min, whereas in the untreated sample it got absorbed within 3 s. ATR-FTIR showed the presence of various -CFx molecule in the plasma treated sample. Electron spin resonance (ESR) analysis indicated formation of more free radicals on cotton textile in the He plasma treated sample. Secondary ion mass spectrometry (SIMS) analysis showed strong molecular peak of F" at 19 amu in addition to significant decrease of O" and OH molecular peaks at 16 and 17 amu, respectively in the plasma treated sample. SIMS molecular image confirmed that there was no blockage of inter-fibre spacing in the plasma treated sample.
