Improvement of wettability and absorbancy of textile using atmospheric pressure dielectric barrier discharge

Abstract

In this study, cotton textile samples, commonly used in making quilt covers were subjected to atmospheric pressure dielectric barrier discharge treatment to study their surface wettability and absorbancy. Samples were treated in the discharge using a rotatory mechanism and the effects of plasma treatment were examined by contact angle measurement and weight measurement. Air plasma treatment was successful in incorporating hydrophilic functional groups on the textile surface due to which wettability as well as absorbancy immediately after the treatment were highly improved. Effects of plasma treatment started to appear only after 20 cycles (9 mins) and got saturated after 24 cycles (10.8 mins) of treatment. The contact angle reduced from 137 ° (untreated sample) to a value less than 30 ° while absorbancy increased by more than two times as compared to untreated sample. Also, the aging behavior of the plasma treated samples were studied for about a week after plasma treatment. It was observed that the induced oxygen containing groups re-oriented into the bulk of the material during their storage in the environment due to which initial properties of the samples recovered gradually. Our results indicate that low temperature plasma can be successfully applied to modify the properties of textiles and textile industries could utilize this by standardization.

Application of Plasma Activation in Flame-Retardant Treatment for Cotton Fabric

“…In general, under the influence of atmospheric plasma, C–C/CH groups decreased while the oxygen groups increased and especially the new group O=C–O appeared. This phenomenon was also observed in [ 30 , 32 , 33 , 34 ] when the cotton fabric was treated with oxygen plasma. Thus, it is evident from XPS analysis that the APDBD plasma treatment has increased the oxygen functional groups, it made the cotton fabric more active, promoting the reaction between cellulose and FRs.…”

“…This presence characterizes DBD over other types of plasma, the plasma in DBD is cold because of the presence of the dielectric layer, which limits the heating current in the circuit while the displacement current has not any heating effects [ 24 ]. Thanks to these advantages, DBD plasma has been used for the surface activation before different functional finishes [ 19 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ].…”

Atmospheric pressure dual RF-LF frequency discharge: influence of LF voltage amplitude on the RF discharge behavior

“…DBDs have many applications including polymer treatment [1], ozone generation [2], air flow control [3], plasma medicine [4]. High quality thin films like water barrier [5][6][7][8][9] or antireflective and passivating film for photovoltaic cells [10][11][12][13] are synthesized using diffuse, streamer-free, linear DBD, easy to scale up for in-line production in conditions similar to corona treatment. One of the key issues for applications is the low power of diffuse DBD which often limits the precursor decomposition and the thin film growth rate.…”
