Antimikrobiyal Medikal Tekstil Ürünleri için Oleuropein Uygulaması

The olive plant has been an important source of nutrition and medicine of the Mediterranean. In this study it is aimed to design a textile product conserve oleuropein compound as a medical textile. Oleuropein was used in different concentrations with different cross-linker and applied to cotton fabric by pad-drycure method. FTIR-ATR and SEM were used to examine the presence of the oleuropein on the cotton fabrics. The oleuropein applied cotton fabrics antimicrobial activity test was performed against both gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria. The durability of the antimicrobial activity of cotton fabrics was tested after 10 washing cycles at 40 °C for 30 min. Tensile strength tests of the fabrics were performed to evaluate the effect of oleuropein solution pH value changes. Air permeability and whiteness values of fabrics were performed on the fabrics before and after the treatment with oleuropei

Electrostatic self-assembly dyeing of cotton fabrics

A new approach to the dyeing of cotton fabrics using an electrostatic self-assembly method was evaluated. Cotton fabrics were pretreated with 2,3-epoxypropyltrimethylammonuium chloride and cationic charges were produced on the fabric surfaces. For the dyeing of cotton fabric, reactive and acid dyes were used. Oppositely charged anionic reactive/acid dyes and cationic poly(diallyldimethylammonium chloride) were alternately deposited on the surface of cationised cotton fabrics. Ten multilayer films of dye/poly(diallyldimethylammonium chloride) were deposited on the cotton fabric surfaces using a padder. The build-up of the multilayer films and the level of colour strength (K/S) achieved are discussed. Samples of cotton fabrics were also dyed with the same dyes, but using the exhaust method, and both types of dyed samples were compared. The washing, rubbing and light fastness properties were evaluated for the dyed fabrics

Nano-TiO2 Based Multilayer Film Deposition on Cotton Fabrics for UV-Protection

Nano-TiO2 based multilayer nanocomposite films were fabricated on cationically modified woven cotton fabrics by layer-by-layer molecular self-assembly technique. Cationization process was used to obtain cationic surface charge on cotton fabrics. Attenuated total reflectance Fourier transform infrared spectroscopy analyses were used to verify the presence of cationic surface charge and multilayer films deposited on the fabrics. Scanning electron microscope micrographs of poly(sodium 4-styrene sulfonate)/TiO2, nano polyurethane/TiO2, and TiO2/poly(diallyldimethylammonium chloride) multilayer films deposited on cotton fabrics were taken. With nano-TiO2 based multilayer film deposition, the protection of cotton fabrics against UV radiation is enhanced. The UV protection durability of the self-assembled multilayer films deposited on the cotton fabrics was analyzed after 10 and 20 washing cycles at 40 degrees C for 30 min. Air permeability and whiteness value analysis were performed on the untreated and multilayer film deposited cotton fabrics. The effect of layer-by-layer deposition process on tensile strength properties of the warp and weft yams was determined
