Investigation on Fire Retardancy Properties of Boric Acid Doped Textile Materials

One way to better protect combustible materials against initiating fires is the use of flame retardants. Every day we come across new innovations particularly in the areas of flame retardant fibres and chemicals. This study investigates fire retardancy effect of boron on two cotton fabrics. Boron can soluble in water, colourless and capable of melting by heat. Boron is highly resistant to fire due to the melting temperature of 2300°C. Because of this property, it is used as a flame-retardant material. The objective of this study was to examine the feasibility of imparting flame-retarding functions to different textile materials through the application of boric acid with impregnation methods. Different concentrations of boric acid nanoparticles were examined to optimize the flame-retarding functions. Eventually, 45° inclined combustion test are applied to the samples and examined the changes in strength of the samples. In this research; the aim is to bring in flame-retarding functions to different fabrics

Effects of Textile Materials Harmful to Human Health

Comprising the ecology of textile production, human ecology, as well as the waste ecology, the textile ecology aims not to harm environment and people during all phases of the textile production, from fabric to garment production. Several processes are applied to textiles, before the end product is obtained. We are intending to take into consideration all phases of fabric and garment production, including the applied processes as well as the used materials and chemicals. The remaining consumers also have a role in the pollution chain of textile industry. Apparel products, purchased and used by consumers, contain chemicals harmful for the human health, and after washing, the environmental impact of these products is inevitable. In this study, we investigate the effects of textile materials harmful for the human health

Investigation on Water Retention Properties of Boric Acid Doped Textile Surfaces

During the summer periods, the excellent absorbency and high water retention capacity of textile materials is important to eliminate the disturbing effect of perspiration. In this study, water retention properties of boric acid-doped textile surfaces has been investigated. For this purposes different proportions of boric acid were applied to 100% cotton fabric by means of impregnation method. Then, water retention was tested according to DIN 53923 standard, as a percentage of the water retention rate. The results were analyzed

Determination of Radiation Shielding Properties of Cotton Polyester Blend Fabric Coated with Different Barite Rate

Using radiation in industry and medicine brings its hazardous effects. On account of this, people have started to be exposed to extra radiation. Thus radiation protection is developed in parallel with the utilization of radiation. In order to be protected from radiation three different criteria have to be taken into account, these are time, distance and the shielding. Shielding is the most effective way. An effective shield should cause a large energy loss on a small distance without emission of more hazardous radiation. In the world, more than three-hundred nuclear facilities have been used to fulfill the needs in the fields of scientific research, energy, agriculture and industry. In addition to this in medical centres radiation beams have been used for treatment and diagnosis. It is extremely important to protect the human body from radioactive rays. Barite is a mineral which can be used for shielding because of barium, which is a high atomic number element. The shielding property of barite is utilized in fabrics. Barite coated fabrics having characteristics of retaining radiation was obtained by penetrating barite into the fabrics via coating method. The linear attenuation coefficients (μ) of the coated barite fabrics were measured at the photon energies of 662, 1173 and 1332 keV obtained from ^{137}Cs and ^{60}Co γ-ray sources, respectively. As detailed elsewhere, the measurement has been performed using the gamma spectrometer that contains NaI(Tl) connected to 16k channels multi-channel-analyser. In this study, cotton polyester blend fabric was used. To apply barite mineral to fabric via coating method, it was grinded to a size of 2-10 microns by using jaw crushers. FK 800/N type transparent compound was used as adhesive. The coated fabrics were prepared with different volumes of barite. For this purposes four different types of fabrics have been produced, where the rate of barite was 0%, 40%, 50% and 60%. The results of experiments show that barite coated fabrics have blocked radiation. When barite ratio increases, the amount of absorbed radiation also increases

Level of Knowledge about Former Disease Terminology and Medical Terms of Medicine Faculty Students

There are still patients which use obsolete medical terms. People's terminology, rather than the modern terminology, is often used to describe symptoms or diseases. Medical terms can also be replaced with terms inherent to patient's own culture. Seen from this perspective, the knowledge of the former medical terms and the terms used colloquially is very helpful for doctors. The purpose of this study was to investigate the knowledge of former medical terms among the medical students. This study was performed on 102 students of medicine faculty. Students, who gave their consent, were interviewed in a face-to-face fashion. The results of the survey were statistically analyzed
