Surface Resistivity Behavior of Plasma Treated and Plasma Grafted Cotton and Polyester Fabrics

Abstract

Cotton and polyester fabrics are treated with radio-frequency plasma (in air) at different power levels and time intervals, and moisture content and surface resistivity behavior are investigated. Plasma treatment lowers the moisture content of cotton and enhances that of polyester. The surface resistivity of plasma treated cotton is affected by both power level and treatment time, and the surface resistivity of polyester is dramatically reduced after plasma treatment. The two fabrics are subjected to further plasma initiated grafting of acrylamide and acrylonitrile. Polyester has a moisture con tent of up to 3% after plasma initiated grafting. The surface resistivity of cotton is somewhat lowered, whereas that of polyester is drastically lowered after grafting.

Surface Energy and Wettability of Plasma-treated Polyacrylonitrile Fibers

“…Although there is an abundance of literature on the surface wettability of plasma treated materials [6][7][8][9][10][11], it is still not fully described from a theoretical point of view. The aim of the present study is to look further into the effect of plasma treatment on the surface energy and wettability of polyacrylonitrile fibers.…”

Pretreatments of Textiles Prior to Dyeing: Plasma Processing

“…Similarly in situ polymerization is also carried out, in which fabric is treated with gaseous plasma followed by plasma polymerization of monomer vapour onto the fabric surface in the plasma reactor. Bhat and Benjamin have successfully grafted acrylamide onto cotton and polyester fabrics using RF plasma (Bhat and Benjamin, 1999). They have observed that the crease recovery angle increases and tensile strength decreases slightly.…”

Enhancing Dark Shade Pigment Dyeing of Cotton Fabric Using Plasma Treatment

“…In previous studies [2,3], plasma treatment has been found to be an effective way for improving color yield, levelness, and crocking fastness of pigment dyed fabrics. During plasma treatment, the fiber surface can be modified physically [4][5][6] and chemically [7][8][9]. In physical modification, active plasma species bombarding the fiber surface causes ejection of atoms on the fiber surface [10][11][12].…”
