“…The crosslinkages so formed reduce the absorption property of cotton fibre and thus increase contact angle values. As WRA results reported in a previous study (Lam et al 2010a) suggest, increasing the amount of TiO 2 will improve WRA results, indicating that more crosslinkages will be formed between cotton fibres. The increased amount of crosslinkages will reduce the wetting behaviour of the cotton fibre leading to increased contact angle values.…”

Cotton fabrics were treated with oxygen plasma gas and/or wrinkle-resistant finishing agent with polycarboxylic acid. The results of wicking rate, contact angle and wettability tests revealed that the atmospheric plasma treatment significantly improved hydrophilicity of cotton fiber. Such improvement greatly enhances the effectiveness of post-finishing processes. The study showed that chemical composition of cotton fabric surface changed after plasma and wrinkle-resistant treatment. Chemical composition of surface of treated cotton specimens was evaluated with different characterization methods, namely, FTIR-ATR and EDX. The experimental results are thoroughly discussed.

“…These fibrils then reconnect with formation of new hydrogen bonds to set the fiber in a deformed state. These reformed bonds prevent the fibrils from returning to their original position even after the bending force has been removed (Lam et al 2010). As there are no recovery forces to bring the deformed fibers back to their original shape/position, this phenomenon creates creases in cotton fabric.…”

Crease-resistant functionalization of cotton fabric was carried out using a combination of monofunctional carboxylic acid-based precursors, i.e. acrylic acid and dodecanoic acid. The reaction of precursors with cotton was carried out in situ using helium atmospheric pressure plasma at low frequency. After the treatment, a 40 % increase in CRA was achieved. The functional property developed after the treatment was durable against both solvent and soap washing. The effect of various parameters, such as the concentration of the precursor, helium flow rate, discharge power density and treatment time, on functionalization was investigated. Plasma was characterized using oscilloscope and optical emission spectroscopy. Modification of the chemical nature of the fabric surface was characterized by ATR-FTIR. The study of the surface morphology by FE-SEM revealed the formation of a uniform thin layer on individual fibers. The loss in tearing strength was limited to 28 %, while tensile strength remained unaffected. The plasma characteristics were correlated with crease-resistant functionalization.

“…TiO 2 P 25 was used for textile nanocoatings preparation by other researchers as well (Bozzi et al, 2005 a, b;Qi et al, 2007;Texlor et al, 2007). In addition, nano-TiO 2 added in the wrinkle-resistant treatment of cotton fabric could act as a multi-functional finishing agent to improve the UV protection property (Lam et al, 2010). Composite titania (TiO 2 ) and silica (SiO 2 ) coatings are used to prevent fibres from photooxidative damages.…”
