Spacer fabric is a three-dimensional structure that obtained by the connection of two parallel fabric surfaces with the connection threads. Spacer fabrics are widely used for their several functional advantages that they provide unlike conventional fabrics. Compressibility is one of the important functional parameters for these fabric structures. The compressibility values of the spacer fabrics are measured based on the ISO 3386-1 standard. However, this standard is used for structures that have non-axial shear during compression such as foam, sponge and so on. It is thought that this standard is not suitable for spacer fabric structures due to the shear deformation which occurs during the measurement of compressibility. For this purpose, as in accordance with spacer fabrics end-use area, a new test system been proposed to measure of compressibility that prevents shear during the test. Thus, it is aimed to prevent the shear deformation and the deviant results obtained during the test. Within the scope of the study, the compressibility properties of spacer fabric structures, which have undergone different thicknesses and different finishing processes, were measured according to both ISO 3386-1 and the new proposed test method. When the results were compared, it was observed that the results obtained in the new proposed test setup were higher and the difference between the measured results according to both test methods was statistically significant for α = 0.05.

In this study, polypropylene fabric was modified with two types of ionic liquids such as 1- ethyl-2,3- dimethylimidazolium ethyl sulfate (EIL) (2, 6, 10 %w/v in ethanol) and methyl-trin-butylammonium methyl sulfate (10, 15, 20 %w/v in ethanol)at different concentrations. Before modification, the fabrics were pre- treated with chromic acid to activate the surface. The effect of the modifications was investigated by thermogravimetric analysis, surface resistivity measurements and scanning electron microscopy. The pre- treatment changed surface resistivity from 1010 to 1013 ohm/sq. The modifications with the ionic liquids decreased surface resistivity of the PP fabrics short and long-term periods in the range of 106 - 108 ohm/sq. Increasing the concentration of the ionic liquids can be considered as an efficient way to reduce the surface resistivity of PP. Thermal stability of the PP altered after modification. It was observed that a coating layer formed on surface of the fabric and in the gaps of the yarns of P P with modification. This environmentally- friendly method can be used as an alternative way for improving conductivity of PP fabrics generally characterized by their high surface resistivity.

The present article aims to make a preliminary analyze regarding the fibrous composition of an "opreg"(part of a female folk costume composed of a richly decorated piece of fabric and long fringes applied on the lower edge) from the modern-contemporary period, using two micro-destructive methods: Scanning Electron Microscopy (SEM) and optical microscopy. In order to have a better understanding and a precise result, different fibres from the opreg were analyzed- brightly colored cotton yarn (green, pink, lilac) together with synthetic silver and gold composite yarns (lurex). Hand-made textiles have a very important meaning for our history, therefore it is imperious to know what kind of fibres were used in order to be able to create an adequate environment to preserve them. Further analyzes will be carried out in order to have a more detailed image about opreg characteristics and how it was obtained.

Ring spinning is one of the oldest and most widely used spinning technology. Recently, many alternative spinning technologies have been introduced. Some of these technologies work on completely different working principle while some of them were developed from conventional system with some modifications. Siro- spun technology which two strands are fed into drafting zone simultaneously is one of the systems that developed from conventional ring spinning. This study focuses on development of three-roving yarn production system that was inspired from siro-spun technology. Roving funnel and delivery cylinder used in siro-spun technology were redesigned for three-roving yarn production and attached on conventional system. Three-roving yarns produced in ring spinning machine were compared with three plied yarns in terms of physical, mechanical and structural properties. For better assessment of this new system, different raw material types were used in yarn production. Results showed that three-roving yarns have better hairiness values and similar mechanical properties for all raw material types. However, unevenness still needs to be improved by further developments on this new system.

Wound healing represents one of the most important processes evaluated in the biomedical field. In this regard, healing is defined as a dynamic and complex process in which the tissue integrity and the normal functions of the damaged tissue are restored. The purpose of this research was to achieve the main characteristics of an ideal wound dressing to prevent maceration, provide a moist environment, remove the exudate that is accumulated from the wound and to maintain a proper permeability to the wound bed. Different hydrogels were designed and developed through the esterification reaction of polyvinyl alcohol (PVA) with gelatin (GELL). The hydrogels were prepared in various weight ratios of PVA:GELL (4:1 and 1:4), by adding rosemary essential oil as an active compound. The incorporation of Rosemarinus officinalis L (rosemary) essential oil in PVA/GELL hydrogels represents a potential method for the improvement of the wound healing process. Further, the developed hydrogels were applied by immersion on cotton gauze. The synthetized specimens were evaluated from morphological and rheological point of view, by performing Optical Microscopy, fluid uptake ability and porosity measurements.

The increase in daily usage of electrical and electronic tools simplify the lives of human beings, on the other hand, they also create an enormous electromagnetic pollution. In industrial applications, electromagnetic shielding materials are used to prevent these electromagnetic signals. The studies on human health against the electromagnetic pollution was determined that the widely usage of these electronic devices increases the risk of cancer. Especially in low frequency fields, the most consistent evidence is obtained in childhood leukemia [1]. In order to reduce the damage of these electromagnetic waves, researches have been still made on the electromagnetic shielding effectiveness. Electrically conductive technical textiles are also investigated for this aim. Different textile structures such as knitted, woven, composite or coated textiles etc and also different conductive yarns are produced to prevent these harmful waves [2-5].In this study, it is aimed to investigate the electromagnetic shielding performances of conductive knitted fabrics. In order to search the efficiency of these fabrics, single jersey and interlock knitted structures are produced. By using these fabrics, two different types of double-layered fabric structures are formed and the shielding effectiveness of these structures are investigated experimentally [6}.

Today, graphene oxide has been significantly used in many technological sectors, medical sectors as well in textiles due to its abundant applications and dominant characteristics. Graphene oxide is basically a mono layered material synthesized by the oxidation of graphite by the addition of multiple functional groups containing oxygen such as alcohols, carboxylic acids and epoxides and presenting a 2-diamentional honeycomb structure. On the textile surfaces the grapheme oxide can be applied through Pad dry-cure, Dip dry-cure and Spray coating methods. However, the most appropriate method is dipping of the fabric into the graphene suspension and the process is followed by drying and curing techniques. Initially, the fabric swatches have been cut out in a suitable size according to the padder or adjustments on the machine can also be done. 100% pure cotton, polyester, cotton polyester blend, silk, aramids and acrylics have been used as a substrate for the application of graphene to imparts different functional properties. The oxygen content is reduced resulting the increase in the interlayer spacing’s well as functionalization. The oxygen containing groups have been removed with the repossession of the conjugated structure. The reduced graphene oxide has the higher strength as well as high electrical and thermal conductivity which effect the final performance of a materials.

Nowadays, too much water, energy, chemical substances are consumed for the conventional textile finishing processes and more chemicals are exposed to the environmental load. In our world of diminishing resources, the most ideal way of using the available resources has been inevitable in the name of all living things on earth. In order to alleviate the environmental burden and increase the green production understanding, the textile finishing sector continues to work as in other sectors. The chemicals used in the studies are minimized to be preferred environmentally friendly substances. Enzymes used in textile finishing, ultrasound technology and use of ozone as oxidizing agents can be seen as the successful results of these studies [1-4]. In this study, processes that can reduce the environmental load in denim finishing processes were investigated with ozone gas used in many fields in recent years. Denim fabrics were treated with ozone and compared with other conventional denim finishing methods. In this study, which is performed in order to improve the bleaching process with ozone, it is envisaged to reduce the chemicals and water used in conventional denim finishing. The operations were carried out on a total of 20 pants, which were sizing and desized pants. In addition, preliminary trials were carried out at acidic, basic and neutral pHs to examine the effect of pH change on the ozone bleaching process. I n accordance with the results of previous studies, it was decided to make the best humidity rate of 60%. Ozone concentration was chosen as 100 g/m3 and 200 g/m3 . In addition to these, ozone application time was determined as 20 minutes. Weight loss, tear strength and color measurement analysis of the fabrics were performed before and after the ozone processes.

In the present paper work it was evaluated the degradation degree of textile material after different types of exposure using micro-destructive methods such as: Scanning Electron Microscopy (SEM), stereomicroscope and Datacolor spectrophotometer. Thus, samples of cotton fabrics were exposed in three different methods: first – outdoors, to natural conditions, second – at a temperature of 60⁰C in an oven and third – buried in commercial plant soil in closed recipients. After 72 hours and 216 hour, specimens of the samples were taken and evaluated. Thereby, microscopic analyzes revealed that the cotton materials are more degraded after burial. The results obtained were correlated with chromatic parameters (DL*, DC*, DE*) and white degree (Berger and CIE). All the samples have color differences in comparison with the unexposed samples; they also present more saturated color and are darker. Cultural heritage represents our history, thus it is important to know how the environment works on textile materials and this way we can manage better the conservation requirements. Future studies will also be carried out on linen and woolfabrics.
