Plasma processes for wide fabric, film and non-wovens

Progress in Ultrasonic Spray Pyrolysis for Condensed Matter Sciences Developed From Ultrasonic Nebulization Theories Since Michael Faraday

“…A number of previous review articles have been presented on different forms of CVD: thermal CVD [2][3][4][5][6][7][8][9][10][11], plasma enhanced PE-CVD [12][13][14][15][16][17][18][19], hot-wire or hot filament (HWCVD or HFCVD) [20][21][22][23][24][25][26][27][28] and not many of them have been as exhaustive in their respective areas. Pyrolysis, although classified under CVD in some text, has become a wide area of research and technology covering synthesis of new products, qualitative and quantitative spectroscopic analysis of fluids and, lately, alternative route to production of debri-free x-ray sources; these aspects are elaborated further in the sections that follow.…”

Physical and chemical analysis of plasma-treated cotton fabric subjected to wrinkle-resistant finishing

“…Using titanium dioxide (TiO 2 ) as a co-catalyst to improve the crease recovery property has been found feasible to enhance the finishing performance with minimum side effects (Yuen et al 2007; Wang and Chen 2005a, b;Chen and Wang 2006;Lam et al 2010a, b). On the other hand, low temperature plasma pre-treatment improves the functional finishing by causing a sputtering or etching effect that alters the surface characteristics which include a large variety of chemically active functional groups; it roughens the surface of the materials and increases the surface area for reaction between the finishing agent and the fibre (Hwang and Mccord 2005;Wang et al 2008;Kaplan 2004;Rajpreet and Gita 2004). In the past, vacuum plasma systems were used for treating textile materials but such systems needed much space and were energy and time consuming processes which were also inadequate for treating the substrate continuously in mass production processes (Karahan and Ö zdogan 2008).…”

Effect of zinc oxide on flame retardant finishing of plasma pre-treated cotton fabric

“…The active species produced in plasma carry high energy to promote surface functionalization reactions (causing a sputtering or etching effect) to alter the surface characteristics. The treatment incorporated a large variety of chemically active functional groups as well as roughened the surface of the materials (Bourbigot and Duquesne 2007;Hwang and Mccord 2005;Wang et al 2008;Kaplan 2004;Rajpreet and Gita 2004).…”

“…The individual of flame retardant treatment and plasma treatment on cotton fabrics has widely been studied (Well 2008;Holme 2007;Lam et al 2010;Bourbigot and Duquesne 2007;Qiu 2007, 2008;Hwang and Mccord 2005;Kaplan 2004;Rajpreet and Gita 2004;Wu andYang 2006, 2008). However, very little research has been conducted to study the plasma pre-treated cotton fabrics subjected to FR-CL-PA treatment in combination with ZnO/nano-ZnO as co-catalyst.…”
