“…Loading of Ag/TiO 2 NC, regardless of the loading sequence, induces colour changes of cotton fabrics, especially for samples dyed with yellow and red reactive dye ( Selvam and Sundrarajan (2012) attributed this effect to the higher uptake of reactive dye onto nanoparticulate functionalized cotton. However, in our case this is not true, because loading of Ag/TiO 2 NC on cotton was performed during or after dyeing and not before dyeing.…”

The cellulose fabrics made from 100 % cotton with antibacterial and UV protective properties were successfully created by loading of Ag/TiO 2 nanocomposite during and after dyeing with yellow, red and blue reactive dye. Blank dyeing (dyeing with all chemicals except dye) was performed to show that reactive dyes have an ability to increase the adsorption and adhesion of Ag/TiO 2 nanocomposite on cotton fabrics. The colour of the samples before and after washing and exposure to artificial light was measured by reflectance spectroscopy. The presence of nanocomposite on samples was confirmed by scanning electron microscope. The increased adsorption capacity of cotton towards Ag/TiO 2 nanocomposite due to the presence of reactive dyes was confirmed by measuring the quantity of silver using inductively coupled plasma mass spectroscopy. The same samples showed excellent UV protective properties with UV protection factor (UPF 50?), and excellent antibacterial properties against E. coli and S. aureus. Due to a good adhesion of nanocomposite on samples where loading of nanocomposite and dyeing with reactive dye was performed simultaneously, the samples retained their excellent protective properties after repetitive washing cycles.

“…On the basis of FTIR analysis, they found the formation of strong hydrogen bonds between HPC (-OH group) and PVP (C=O group) by the shift of absorption bands. Also, interaction between PVP and cotton was observed by Selvam and Sundrarajan (2012). Additionally, Hong et al (2010) observed broadened and shifted C=O stretching bands of the silver/PVP nanocpomosite compared to the PVP powder band.…”

“…The peak at 1647 cm -1 corresponded to the stretching vibrations of C=O in the PVP. Other peaks at 1281 and 1425 cm -1 referred to the C-N stretching vibration and the CH 2 groups in the pyrrole ring of PVP (Selvam and Sundrarajan 2012). On the FTIR/ ATR spectrum of CO10AgNW fabric, the broad band peak corresponding to -OH stretching shifted to a lower wave number from 3332 cm -1 (Fig.…”

A study on the functionalization of cotton and viscose fabrics to achieve bifunctional conductive and antibacterial properties was carried out; 0.5 wt% AgNW ethanolic colloid was prepared, and fabrics were dipped and dried in the colloid 1, 10 and 15 times. After one dipping, both fabrics remained nonconductive, and the surface resistance (R s ) of cotton was 4.9 9 10 10 and of viscose 3.6 9 10 11 X. Excellent conductivity properties were shown in cotton fabric after 10 dippings (20 X) and in viscose fabric after 15 dippings (46 X). The Ag content of these fabrics was 53.3 and 52.3% (SEM/EDX analysis) and 13.77 and 14.12% (TG/DTG analysis) for cotton and viscose, respectively. XRD analysis revealed the presence of AgNWs on the fabric surface. FTIR/ATR, Raman and TG analysis confirmed the effects of modifications. The AgNW layers on both fabric surfaces were resistant to abrasion. After 50 washes of the modified cotton fabric, R s increased from 20 to 195 X. The AgNW layer was stable and the fabric still highly conductive. However, viscose fabric became nonconductive after two washes, and the surface resistance increased from 46 to 1.4 9 10 11 X. The tensile strength of cotton modified with AgNWs increased by about 49% and for viscose decreased by about 27%. AgNW-modified cotton fabric showed a significant antibacterial effect against S. aureus and K. pneumoniae bacteria. The presented method is more suitable for cotton because the modified cotton fabric retains the mechanical and conductive properties even after many washes.

“…The natural antimicrobial agents are used to inhibit the growth of mold and bacteria on fabric. A large class of the antimicrobial agents used in textile includes oregano-metallic, phenol, quaternary ammonium salts and oregano silicones [25]. The microbial agents should be safe and biodegradable and should not be toxic and it should be noted if the active agent used in the antimicrobial dyes is effective and can be used safely.…”

Abstract:Hazelnut is of great important in agricultural export of our country. It has an annual export of one and a half billion dollars. Every new product that will increase the value of the nut is very important. In recent years, natural dye materials used especially in textile materials are important and those of plant origin are preferred. For this purpose, we have made a natural dye extracts from hazelnut nuthusk after collected, dried and grinded of samples. Some biological activities have been carried out showing the suitability for industrial use of the dye extracts obtained from hazelnut nuthusk. Within the scope of our study, the effect of extracts obtained from the hazelnut nuthusk of the Düzce region was evaluated on anti-bacterial and DNA protection. From the extracts obtained, antibacterial activity tests were analyzed by disk diffusion method using 3 different standard bacterial strains as S. aureus, E. coli and P. aeruginosa. pBR322 plasmid DNA and UV-C method was used for DNA protective activity. Four different extracts of dyestuff has showed antibacterial activities to S. Aureus and two different of them P. aeruginosa but none of the samples antibacterial properties to E. coli bacterial strains. It has been determined that the all of dyestuffs extracts obtained from the hazelnut nuthusk have potential for protection against the effects of UV-C and H 2 O 2 on DNA.
