The study is aimed to assess the effects of squeezed roller pressure, dryer temperature, yarn count, machine speed (rpm) on cotton fabric weaving. Coarser and finer cotton yarn samples were prepared using sizing solution BENSIZE 850. Different size box temperature, yarn count, fabric construction, machine speed, squeeze roller pressure were considered to construct different weaving designs to study yarn breakages parameter. A warping plan was designed on TAROKO V5.4 (190325) software. The results established that size box lower temperature and higher machine speed provide the smallest amount yarn break during weaving for coarser cotton yarn and the highest for finer cotton yarn. Size box higher temperature and lower machine speed provide maximum yarn breakage during weaving coarser cotton yarn and minimum for fine yarn. Size penetration is uniform, which provides a higher strength of the yarn to less breakage. This aspect of the research suggested that higher yarn strength gives a lesser amount of breakage.展开更多

In recent years, the industry has faced challenges due to changing global fashion trends and increasing competition from other manufacturing countries. One of the latest trends in the fashion industry is micro seasonal fashion, which has significant impacts on the RMG industry of Bangladesh. The purpose of this study is to examine the impact of micro seasonal fashion on the RMG industry of Bangladesh. It will examine the changes in buyer and consumer behavior and demand patterns, the implications for manufacturers and suppliers, and the strategies adopted by industry players to adapt to this trend. The emergence of micro seasonal fashion has disorderly the traditional seasonal cycle of the fashion industry. Consumers are no longer satisfied with the two-season model of spring/summer and fall/winter, but instead demand new styles and trends every few weeks. This trend has created opportunities for the RMG industry of Bangladesh to cater to the fast-changing demands of consumers. Micro Seasonal Fashion also poses significant challenges for the industry. Manufacturers and suppliers must be able to produce and deliver garments quickly and efficiently, while ensuring high quality and sustainability standards. This requires investments in technology, supply chain management, and training of workers. To address these challenges, industry players in Bangladesh have adopted several strategies, such as diversifying product offerings, investing in technology and innovation, and enhancing sustainability practices. These strategies have helped the industry to remain competitive and meet the demands of fast-changing consumer preferences. The industry must be able to adapt quickly to the changing demands of consumers and invest in technology and sustainability practices to remain competitive. With the right strategies and investments, the RMG industry of Bangladesh can control the opportunities presented by micro seasonal fashion and continue to be a major player in the global fashion industry.展开更多

For this research, we used different knitted structures, yarn count and stitch length and for finding data different types of m/c are used which are discussed later. This study is based on finish GSM of Pique, Lacoste and Jersey Knit Fabrics where various kinds of yarn count, GSM and Stitch length are used to justify the experiment. The relation of count and Stitch length with GSM is inversely proportional. When count and Stitch length increases, GSM decreases which is proved through this paper by using both the expected and experimental data. For writing this paper we have distinguished both the theoretical as well as practical implications from the industry and tried to find out adjustable points of fabrics Count, GSM and Stitch Length along with Shrinkage%, Fabric width, Spirality. This paper provides a reliable result which will help selection of count, GSM and Stitch length for making of Pique, Lacoste and Jersey knit fabrics with or without Lycra maintaining the Shrinkage%, spirality%, pilling grade in an acceptable limit. This paper logically shows that GSM, shrinkage and spirality vary when structure, yarn count, and stitch length vary.展开更多

Emergence of different apparel manufacturing nations, rapid development of global supply chains and increasingly higher demand for fast fashion items are exposing the apparel manufacturers to competitive product prices. Alongside, the persistent global depression has also forced the apparel business to curtail the prices to remain sustainable in the industry. Garment costing is the systematic process of meticulously calculating the total cost of a certain quantity of garments from raw material purchase to converting them to the final products, plus other terms and conditions stated by the customers. The sum of these costs adding the profit margin is the selling price. This research outlines the process of preparing cost sheets for basic garment products. The research proposes a clear method of generating easily understandable, complete garment cost sheets for the apparel industry.展开更多

文摘Sizing is an inherent part of weaving works, consisting in the coating of the warp yarn with a polymeric adhesive, such as starch, in order to assist efficient weaving. The study is aimed to assess the effects of squeezed roller pressure, dryer temperature, yarn count, machine speed (rpm) on cotton fabric weaving. Coarser and finer cotton yarn samples were prepared using sizing solution BENSIZE 850. Different size box temperature, yarn count, fabric construction, machine speed, squeeze roller pressure were considered to construct different weaving designs to study yarn breakages parameter. A warping plan was designed on TAROKO V5.4 (190325) software. The results established that size box lower temperature and higher machine speed provide the smallest amount yarn break during weaving for coarser cotton yarn and the highest for finer cotton yarn. Size box higher temperature and lower machine speed provide maximum yarn breakage during weaving coarser cotton yarn and minimum for fine yarn. Size penetration is uniform, which provides a higher strength of the yarn to less breakage. This aspect of the research suggested that higher yarn strength gives a lesser amount of breakage.

文摘The Ready-Made Garments (RMG) industry is a major contributor to the economy of Bangladesh, accounting for over 80% of the country’s total exports. In recent years, the industry has faced challenges due to changing global fashion trends and increasing competition from other manufacturing countries. One of the latest trends in the fashion industry is micro seasonal fashion, which has significant impacts on the RMG industry of Bangladesh. The purpose of this study is to examine the impact of micro seasonal fashion on the RMG industry of Bangladesh. It will examine the changes in buyer and consumer behavior and demand patterns, the implications for manufacturers and suppliers, and the strategies adopted by industry players to adapt to this trend. The emergence of micro seasonal fashion has disorderly the traditional seasonal cycle of the fashion industry. Consumers are no longer satisfied with the two-season model of spring/summer and fall/winter, but instead demand new styles and trends every few weeks. This trend has created opportunities for the RMG industry of Bangladesh to cater to the fast-changing demands of consumers. Micro Seasonal Fashion also poses significant challenges for the industry. Manufacturers and suppliers must be able to produce and deliver garments quickly and efficiently, while ensuring high quality and sustainability standards. This requires investments in technology, supply chain management, and training of workers. To address these challenges, industry players in Bangladesh have adopted several strategies, such as diversifying product offerings, investing in technology and innovation, and enhancing sustainability practices. These strategies have helped the industry to remain competitive and meet the demands of fast-changing consumer preferences. The industry must be able to adapt quickly to the changing demands of consumers and invest in technology and sustainability practices to remain competitive. With the right strategies and investments, the RMG industry of Bangladesh can control the opportunities presented by micro seasonal fashion and continue to be a major player in the global fashion industry.
文摘This work reports the successful outcomes to process the polyester, acrylic and wool fiber along with jute fiber exclusively using existing jute processing machineries for manufacturing the 241 tex jute blended yarn. The blending was performed at feeding stage of breaker carding machine and blending ratio of jute and polyester/acrylic/wool fibers is 80:20. Manufacturing of jute blended yarns will create a new opportunity for extending the uses of jute fibers in value added jute products. The present work is concerned with the investigation of physical properties such as tenacity, elongation % at break, quality ratio, unevenness, imperfections (thick, thin & neps) and hairiness of manufactured jute blended yarns. The jute-polyester (80/20) blended yarn shows the higher strength and more evenness compared to jute-acrylic (80/20), jute-wool (80/20) blended and 100% jute yarn.
文摘The relationship of Count, GSM (Gram per Square meter), and Stitch Length, Shrinkage%, spirality% and pilling are discussed by this paper among Pique, Lacoste and Jersey knit structures with or without Lycra “3% - 5%”. For this research, we used different knitted structures, yarn count and stitch length and for finding data different types of m/c are used which are discussed later. This study is based on finish GSM of Pique, Lacoste and Jersey Knit Fabrics where various kinds of yarn count, GSM and Stitch length are used to justify the experiment. The relation of count and Stitch length with GSM is inversely proportional. When count and Stitch length increases, GSM decreases which is proved through this paper by using both the expected and experimental data. For writing this paper we have distinguished both the theoretical as well as practical implications from the industry and tried to find out adjustable points of fabrics Count, GSM and Stitch Length along with Shrinkage%, Fabric width, Spirality. This paper provides a reliable result which will help selection of count, GSM and Stitch length for making of Pique, Lacoste and Jersey knit fabrics with or without Lycra maintaining the Shrinkage%, spirality%, pilling grade in an acceptable limit. This paper logically shows that GSM, shrinkage and spirality vary when structure, yarn count, and stitch length vary.

文摘The increasing use of traditional agricultural plastic mulch films(PMs)has raised significant environ-mental concerns,prompting the search for sustainable alternatives.Soil-biodegradable mulch films(BDMs)are often proposed as eco-friendly replacements;however,their widespread adoption remains contentious.This review employs a comparative life cycle assessment perspective to evaluate the environmental impact of PMs and BDMs across their production,use,and end-of-life stages,providing strategies to mitigate their impact on agroecosystems.BDMs generally exhibit lower energy use and greenhouse gas emissions than PMs but contribute to greater land-use demands.Reported eutrophica-tion and acidification potentials are less consistent,varying based on feedstock types and the scope of assessment of BDM,as well as the end-of-life management of PM.The environmental burden of both mulch types is influenced by the life cycle stage,polymer composition,farming practices,additives,film thickness,and local climatic conditions.The manufacturing stage is a major contributor to energy use and greenhouse gas emissions for both PMs and BDMs,despite their shared benefits of increasing crop yields.However,post-use impacts are more pronounced for PMs,driven by end-of-life strategy and adsorbed waste content.While starch-based BDMs offer a more sustainable alternative to PMs,un-certainties regarding the residence time of BDM residues in soil(albeit shorter than PM residues)and their effects on soil health,coupled with higher production costs,impede widespread adoption.For BDM end-of-life,soil biodegradation is recommended.Energy and material recovery options are crucial for PM end-of-life,with mechanical recycling preferred,although it requires addressing eutrophication and human toxicity.This review discusses these complexities within specific contexts and provides action-able insights to guide the sustainable integration of mulch films into agricultural practices.
文摘Apparel business is one of the oldest global businesses. Emergence of different apparel manufacturing nations, rapid development of global supply chains and increasingly higher demand for fast fashion items are exposing the apparel manufacturers to competitive product prices. Alongside, the persistent global depression has also forced the apparel business to curtail the prices to remain sustainable in the industry. Garment costing is the systematic process of meticulously calculating the total cost of a certain quantity of garments from raw material purchase to converting them to the final products, plus other terms and conditions stated by the customers. The sum of these costs adding the profit margin is the selling price. This research outlines the process of preparing cost sheets for basic garment products. The research proposes a clear method of generating easily understandable, complete garment cost sheets for the apparel industry.
