Functionalization of cellulose-containing fabrics by plasma and subsequent metal salt treatments

Microwave-assisted TiO2: anatase formation on cotton and viscose fabric surfaces

“…Bands near 1455-1061 cm -1 correspond to C-O stretching and in the range 1200-1400 cm -1 are O-H bending bands (Caschera et al 2014;Ibrahim et al 2012). Karahan and Ö zdoan (2008) did not obtain bands around 1740 cm -1 by atmospheric plasma treatment; however, they obtained this band by Ar plasma treatment.…”

A review of low-temperature plasma treatment of textile materials

“…Hashemizad et al [165] highlighted that using 0.2 % nano TiO 2 on RF oxygen plasma-modified PET fabric was enough to obtain an acceptable UV protection level even after 10th washing cycles. Ibrahim et al [166] treated cotton/polyester (80/20), cotton/linen (50/50), and linen/viscose-polyester (50/ 50) fabric blends with plasma gases namely, oxygen, air, and argon. Then, the plasma pre-treatment was followed by subsequent treatment with certain metal salts (Zn-acetate, Cu-acetate, Al-chloride, and Zr-oxychloride).…”

Nanomaterials for Antibacterial Textiles

“…Some specific examples of these applications in the field of textile wet processing include: (i) multifunctional finishing of cellulosic/polyester blends using Ag-NPs/PVP and ZnO-NPs/HBPAA hybrids along with citric acid as an eco-friendly cross-linking agent (Ibrahim et al, 2013e); (ii) simultaneous functionalization and pigment coloration of cellulosic/wool blends using TiO 2 -NPs along a proper polyacrylate binding agent (Ibrahim et al, 2013h); (iii) development of multifunction cellulosic pigment prints using Ag-, ZnO-, ZrO 2 -, and TiO 2 -NPs individually and in the presence of different binding agents (Ibrahim et al, 2013i); (iv) enhancing antibacterial functionality of pigment printed cotton, linen, and viscose cellulosic fabrics by using an Ag-NPs/ PVP hybrid (Ibrahim et al, 2013a); (v) combined antibacterial finishing and pigment printing of cotton/polyester blends using Ag-NPs/HBPAA (Ibrahim et al, 2013j); (vi) reactive dyeing and antibacterial finishing of cellulosic fabrics using Ag-NPs loaded on HBPAA (Ibrahim et al, 2012c) in one step; (vii) imparting multifunctional properties to cellulose-containing fabrics using poly (acrylic acid)/poly(ethylene glycol) adduct along with Ag-NPs or TiO 2 -NPs (Ibrahim et al, 2012b); and (viii) upgrading of antibacterial, UV protection, and self-cleaning properties of cotton fabrics by treatment with silver-, silica-, and titania-based sols by the dip-coating method (Onar et al, 2011).

“…NANOMATERIALS FOR ANTIBACTERIAL TEXTILES to date are: (i) cell wall damage and increase of cell membrane permeability; (ii) accumulation in the cell membrane, passing through it and disturbing its proper functions; (iii) gradual release of free Ag 1 ions in the bacterial cells followed by generation of reactive oxygen species (ROS) in the presence of dissolved oxygen (Dastjeradi et al, 2009;Ibrahim et al, 2012b;Radetic, 2013): and (iv) interaction of uptaken Ag 1 ions with sulfur-containing proteins in the cell and phosphorous-containing compounds like DNA, thereby disrupting ATP production and DNA replication, and finally leading to cell death (Maillard, 2002;Morones et al, 2005;Marambio-Jones and Hoek, 2010;Rai et al, 2009;Radetic, 2013).
