This research work was intended to discover the effect of super white washing process temperature and OBA (optical brightening agent) concentration on various properties of stretch denim fabric. Different properties like tensile strength, tear strength, dimensional stability, pilling resistance, hand feel performance, color fastness to washing, color fastness to perspiration, color fastness to light were investigated. All experimental tests were carried out according to the ISO (International Organization for Standardization) standards. Stretch denim fabric treated with super white washing process demonstrated better results regarding tensile strength, tear strength and dimensional stability for 35°C temperature and 30g/L OBA concentration along with illustrated moderate to good ratings in different color fastness properties after gradual increase of processing OBA concentration and temperature; although no significant change was observed regarding the grade of color change and color staining for color fastness to wash, color fastness to perspiration and color fastness to light with respect to stretch denim fabric treated with super white washing. The grade for pilling resistance and hand feel performance was comparatively good after the elevation of processing temperature and OBA concentration. The GSM (gram per square meter) of stretch denim fabric also changed accordingly after increasing the OBA concentration and washing process temperature for super white washed stretch denim fabric. The dimensional stability of stretch denim fabric also altered after going through different OBA concentration and washing process temperature.

This research work was intended to analyze the unleashed issues related to apparel trade during COVID-19 pandemic & made an attempt to find the best possible responses to uphold marketing campaigns during & after the pandemic situation. Apparel industries in Asia, the largest global hub of both the textile & apparel import-export trade have been severally damaged by the COVID-19. Over the last one year, the global community had already realized the fact that how pandemic situation disrupted the supply chain management of textile, apparel & fashion manufacturing industries throughout the world. Bangladesh, one of the top ranked garments exporter countries have been facing the burning bridges, due to the scarcity of raw materials & gradual cancelation export orders. The contribution of the apparel industry is more significant for the socio-economic growth of a 3rd world countries like Bangladesh, just because apparel contributes almost 84% of its total export income with the involvement of 4.5 million people approximately. The following research paper conveys a three-fold story. In the very beginning portion, there are some reviews & analysis of the overall scenarios of the COVID-19 pandemic with presence of several business reports, academic journals, market research, manufactures' opinions & stakeholders' strategies. The second phase of the research work forecasts the possible responses need to be projected during & after the pandemic situation. Finally, this study predicts an ideal foot print to cope up with similar sort of situations in future.

Over the last few decades, a lot of innovations and development works had already made denim "classic" in the fashion cycle. The modern consumers of today's world are not only devoting themselves on clothing comfort but also emphasizing on economic and environmental sustainability. As a result, there has been increasing interests in terms of using environment friendly, non-toxic and biodegradable wet process such as super white wash. Though it enlarged higher consumer aspects and market opportunities in the denim washing technology, no research work had done yet regarding to super white wash. It can easily be applied to solid fabrics and finished garments. This research work was intended to analyze the physical and chemical changes of denim fabric while incorporating into super white wash at variable process parameters such as washing process time and machine rpm. Though its prime objective is to improve the whitening effect of textiles and apparels, it also can improve color strength (K/S), color fastness properties (color fastness to washing, color fastness to light, color fastness to perspiration), pilling resistance and fabric handle. In this article, it was demonstrated that all the fabric samples achieved gradual deterioration of tensile strength, tear strength and dimensional stability with the increase of washing process time and machine rpm up to a certain stage. Furthermore, the fabric samples showed better results regarding whitening index (WI), color strength (K/S), pilling resistance, fabric handle and color fastness properties with the gradual rise of washing process time and machine rpm. There were some notable changes in fabric GSM at the following washing conditions.

This research paper was intended to provide a conceptual discussion related to the newly arisen business model termed as "China-Plus-One", which deals with the practice of international trade between China and a 3 rd world Asian country. One of the key achievements of this strategy is that it encourages mutually beneficial trade across geographical boundary. Different world recognized global studies had proclaimed that the Southeast Asiatic region will be the next hotspot of textile and apparel trade due to the availability of raw materials and low paid labor force. As a result, numerous industrial groups of China are looking forward to attaining comparative business advantages by investing at another location of manufacturing in the Southeast Asia. This research paper conveyed a two-fold story. In the very beginning, it was expected to evaluate the comparative market position of the major textile and apparel trade competitors (especially China, Bangladesh and Vietnam). Later on, it analyzed the pattern of rapidly changing business situation due to competitive production factors such as labor cost, logistic support, utility cost, ease of doing business, corruption index etc. Though "China-Plus-One" strategy is a promising one, not that much study hadn't yet taken place regarding it. China-Plus-One strategy appears to be beneficial for both firms that seek to pursue it with a view to risk diversification, cost advantage, product and market diversification. The purpose of this study is to sort out the convergence or divergence of textile and apparel trade in the Southeast Asiatic region due to this business philosophy.

The COVID-19 pandemic is a curse and a threat to global health, development, the economy, and peaceful society because of its massive transmission and high rates of mutation. More than 220 countries have been affected by COVID-19. The world is now facing a drastic situation because of this ongoing virus. Bangladesh is also dealing with this issue, and due to its dense population, it is particularly vulnerable to the spread of COVID-19. Recently, many non-linear systems have been proposed to solve the SIR (Susceptible, Infected, and Recovered) model for predicting Coronavirus cases. In this paper, we have discussed the fractional order SIR epidemic model of a non-fatal disease in a population of a constant size. Using the Laplace Adomian Decomposition method, we get an approximate solution to the model. To predict the dynamic transmission of COVID-19 in Bangladesh, we provide a numerical argument based on real data. We also conducted a comparative analysis among susceptible, infected, and recovered people. Furthermore, the most sensitive parameters for the Basic Reproduction Number (R 0 ) are graphically presented, and the impact of the compartments on the transmission dynamics of the COVID-19 pandemic is thoroughly investigated.
