The use of nano fibers has grown significantly in recent years. These fibers have many advantages over micro fibers, the most important of which is their specific surface area and greater strength. Electrospinning is a conventional process used to prepare fine and uniform polymer nanofibers. The use of this method is limited due to the need for a high potential difference, the need for an electrically conductive collector, and relatively low production speed. Centrifugal spinning technology uses centrifugal force instead of using high voltage to produce nanofiber polymer and is a safer and more affordable option than electrospinning. In this study, centrifugal and electric forces were used simultaneously to produce polyacrylonitrile nanofibers and the effectS of adding centrifugal force to electric forces on the diameter of nanofibers, production rate, percentage of surface porosity, and dye absorption of polyacrylonitrile nanofibers were compared for both methods. The results showed that the use of electrocentrifuge instead of electrospinning can reduce the diameter of nanofibers by 40% and increase the production rate by 68%. On the other hand, increasing the rotation speed in this method leads to a decrease in the diameter of nanofibers and an increase in the specific surface area. Morever, nanofibers produced by this method were 33% more successful than electrospun nanofibers in absorbing colored pollutants. Therefore, the use of these fibers as an effective absorbent for colored wastes is suggested.

Sustainability is the key to ensuring that our actions today do not limit the range of economic, social and environmental options for future generations. In fact, sustainable development is committed to preserving the environment and paying attention to the needs of future generations. The textile and clothing industry is one of the most polluting industries in the world, so special attention should be paid to its sustainability aspects throughout the textile and clothing supply chain. For this purpose, the assessment and improvement of social, environmental and economic effects at each stage of the entire supply chain should be considered. The textile and clothing industry sector is heavily involved in environmental, social, and economic issues, and sustainable design can lead to long-term use and reduce the wastage of materials and products. One of the most important findings of this research is the improvement of the awareness of designers and clothing manufacturers of sustainable development, which plays an important role in the application of the principles of sustainable development in the country. One of the solutions that can be offered in this regard is the optimal use of clothing in the best possible way. Buying clothes that are of high quality and longevity can be the best solution. Another solution is to recycle and make minor changes to the clothes that we do not want to use anymore. The most important solution to coexist with the environment is for people to turn to the business of sharing clothes.

This research has been conducted with the objective of multi-functional finishing on cotton fabric forimproving different properties such as photocatalytic activity, electrical conductivity, UV blocking, andantibacterial. To this end, in situ synthesis of graphene/zinc stannate nanocomposite was carried outand its effect on the cotton properties was investigated. The structure and morphology of the fabricsurface has been examined by field emission scanning electron microscopy (FE-SEM) and its chemicalstructure has been elucidated by X-ray photoelectron spectroscopy (XPS). The electrical conductivityof coated fabrics was improved significantly due to the presence of graphene on the surface of cottonfabrics. The photocatalytic activity of the treated fabrics with graphene/zinc stannate nanocompositewas tested by degradation of methylene blue in aqueous solution under sunlight irradiation, whichdemonstrated excellent photocatalytic efficiency of the nanocomposite. The antibacterial activities of thesamples against two common pathogenic bacteria including Escherichia coli and Staphylococcus aureushave been also assessed, which suggested that the graphene/zinc stannate nanocomposite can functioneffectively as antibacterial agents. Moreover, the nanocomposite finished cotton fabric showed properUV blocking activity.

The aim of this article was to compare of Reactive Dye adsorption isotherm of one- and two-factors on Cotton fabric. In this study, according to the type of fabric used and the two types of dyes used with chemical bases (MCT and MCT/VS), we investigated the effect of three cooperative substances dispersing, urea and penetrating. It should be noted that the Concentration and temperature were also variable. The results of the experiments showed that all three mentioned cooperative materials cause higher penetration and stabilization and improve the stability of both types of dyes mentioned on the tested fabric, in which the use of these materials for both types of dyes is investigated and the results Shown that the order of effect of these materials was different for the two types of dyes. To determine the type of adsorption isotherm, Nernest, Langmuir and Friendlich adsorption isotherms were used and the results indicated that the Langmuir adsorption isotherm is better suited to the test results. This means that the adsorption of RR and RGB Red Reactive dyes by the cellulosic product is superheated. Finally, the results of activation energy data shown that RR dye in the presence of urea and dispersants cooperatives has the lowest activation energy and Arrhenius prediction coefficient, while this has the highest value for RGB dye.

In this study, graphene plates were used to improve the antibacterial and electrical properties of cotton fabric. In this regard, graphite powder was converted to graphene oxide under chemical oxidation test and then converted to graphene oxide sheets by ultrasound and the colloidal solution was loaded on the surface of the fabric by immersion. The physical properties of graphene oxide-modified cotton fabric were evaluated by FTIR and scanning electron microscopy (SEM) methods, and the conductivity of the fabrics by standard methods of parallel electrodes and anti-scatters was also evaluated. Microbiology was examined. The results of SEM and FTIR microscopy images confirmed the presence of graphene oxide sheets, and finally the fabric coated with graphene oxide reduced by sodium hydrosulfite had electrical properties, which varied depending on the concentration of graphene oxide. Graphene oxide coated cotton fabric does not show electrical properties in the presence of other reducing agents. This operation also caused antibacterial properties on the surface of cotton cloth (to prevent the growth of bacteria such as S. aureus and E. coli).

The subject of this article is the study of policy development programs in Iran after the revolution and job dependence in the banking system. Undoubtedly, one of the most important and fundamental pillars of Iran's economy during these four decades has been the banking system, which has left a decisive role throughout the country's economic system. Accordingly, having a healthy banking system is considered one of the most important concerns of the Islamic Republic of Iran. Development programs as a macro policy seek to achieve and implement the policies of the banking system. The main question of the research is what is the position of the banking system in the policy-making of post-revolutionary development plans and how can job dependence in the banking system be explained? The main hypothesis of the article is that each of the economic development programs with a different approach, directly and indirectly took steps to implement banking policies. Although attention to job dependency in the organization is a key element in the performance of any organization, it is not explicitly mentioned in post-revolutionary economic development programs.

Six hundred fifty individuals, including the physical education trainers and students, clothing designers, and textile engineers, participated in this survey. A designed survey questionnaire was employed for data collection. The reliability of the questionnaire was validated using Cronbach's alpha, and the result was 0.86, indicating a high level of internal consistency. The results of our study showed that the shopping value, satisfaction, and loyalty for foreign brands were generally higher than those of Iranian brands and significantly related. The most substantial relation was found to be between brand awareness and the perceived quality of the brand among several other aspects, including the equity, style, fidelity, design & pattern, brand association, the quality of clothing, color and fabric, and price.

Poor interaction between fillers and epoxy matrix is one of the major limitations to developing epoxy composites usage. In this study, effect of corona process on carbon nanotubes reinforced epoxy composite properties was evaluated. The structure and morphology of epoxy composites has been examined by scanning electron microscopy (SEM) and its chemical structure has been elucidated by Fourier transform infrared spectroscopy (FT-IR). Thermal, mechanical and electrical properties of the prepared composites were also assessed. To analyze the relationship between the interfacial interactions in the nanocomposites and tensile performance, a theoretical model germane to the mechanical behaviors of the nanocomposite was applied. According to the results, it was found that the corona modification of carbon nanotubes resulted in breaking of fillers agglomerates and improved their dispersion. The mechanical properties and thermal stability of modified samples were improved with respect to unmodified ones. Moreover, the prepared epoxy composite possessed excellent electrical conductivity.

Nowadays, brands influence various aspects of life and sometimes even represent our ways of life and culture. In this research, we investigate the impact of color index in clothes on customer loyalty by considering the mediation role of the brand character. A descriptive data collection and random sampling method were used in the statistical population of the customers of LC.Waikiki stores in the Mazandaran province. Following the Cochran formula, 384 customers were randomly selected as the sample population and asked to answer a Likert Scale standard questionnaire (a five point scale). The Cronbach's Alpha Coefficient of 0.813 was calculated which confirmed the validity and reliability of the questionnaires. SPSS22 and LISREL8.54 software were used for data analysis of the Kolmogorov–Smirnov, and Kaiser-Meyer-Olkin tests. The results indicate that the clothes’ color has a direct and meaningful effect on the customer loyalty. However, it is observed that the brand’s character and identity in relation to the clothes’ color, play a minor mediation role in the customer loyalty.
