The influence of different experimental conditions on the thermal comfort behavior of polyester-viscose and polyester-cotton ring and MJS yarn fabrics has been studied. The results show that the yarn structure and the fibre cross-sectional shape have a large influence on improving the thermal comfort of woven fabrics. The fabrics made from MJS yarns perform better than those of the ring yarn fa...
This paper presents the improvement of the antimicrobial character of woven fabrics based on cotton. The woven fabrics were cleaned in oxygen plasma and treated by padding with silver chloride and titanium dioxide particles. The existence of silver and titanium on woven fabrics was evidenced by electronic microscope images (SEM, EDAX) and by flame atomic absorption spectrophotometry. The antimi...
Traditional knitted fabrics have been extensively applied in dresses and home decoration, and in recent years, the applications of the fabrics knitted by new technologies and new materials also increase in other fields. The conductive fiber knitted fabrics was used in the article, and its electric properties under transverse stretching were tested and researched. Based on the electric model of ...
In this article a practical mass-spring system was developed to simulate the draping of woven and knitted fabrics. The material properties important to fabric drape, including aerial density, tensile, shear, and bending properties were measured using the Kawabata Evaluation System and the experimental data were incorporated into the mass-spring model to simulate the dynamic draping behavior of ...
rehabiliating bushehr historic fabric and paying to it as an important urban fabric through increasing capabilities and facilities is main concern. bushehr historical fabric can be the consequence of several factors the most important of which is the persian gulf and its past history as a national one. this fabric, is organic, dense, compact, having its own characteristics. one of its main prio...
extended abstractthe occurrence of natural disasters such as the earthquake has been threat human life and caused a great deal homelessness and displacement in the cities. in the early stages of dealing with such conditions one of the more important issues that is noticed by the responsible crisis management organizations is the optimum locating for contemporary settlement and organizing the li...
Due to its environmentally benign character, supercritical carbon dioxide (scCO2) is considered in green chemistry, as a substitute for organic solvents in chemical reactions. In this paper, an innovative approach for preparation of flame retardant cotton fabric was obtained by utilizing supercritical carbon dioxide with co-solvent. A novel phosphorusnitrogen containing piperazine derivative, t...
BACKGROUND Bacteria from the hospital environment, including linens and curtains, are often responsible for hospital-associated infections. The aim of the present study was to evaluate the bactericidal effects of fabrics coated with the hydroxyapatite-binding silver/titanium dioxide ceramic nanocomposite "Earth-plus". METHODS Bactericidal activities of woven and nonwoven fabrics coated with E...
what is called the problems of tehran metropolis now a days, is deep- rooted in the policies ofurban planning in our country. since not far past up to now, immigration from all over the country to tehran, irregular growth of urban population, inconsistency with urban infrastructure development, environmental pollution and low quality of living areas, erosion of self -growing fabric in most area...
