Nahid; Hasan, Md. Jahid This study delves into the pivotal processes of scouring and bleaching in textile manufacturing, elucidating their procedural intricacies, significance, and consequential impacts on fabric properties. Scouring, a foundational step in fabric preparation, entails the removal of natural impurities from fibers through the application of alkaline solutions and mechanical agitation. This process enhances fabric purity, brightness, and preparatory readiness for subsequent treatments such as dyeing or printing. Conversely, bleaching serves to further augment fabric whiteness by expunging residual colorants and impurities, predominantly employing oxidative reactions catalyzed by potent agents like hydrogen peroxide. The experimental methodology delineates the scouring and bleaching procedures in detail, emphasizing crucial stages including preparation, treatment, rinsing, and drying. Environmental considerations regarding proper chemical management and waste disposal are underscored to mitigate potential ecological ramifications. Furthermore, the study sheds light on the escalating adoption of automation and sophisticated methodologies in textile production, aimed at bolstering efficiency and minimizing environmental impact. The comprehensive insights provided herein aim to inform textile industry practitioners, researchers, and stakeholders, facilitating optimized manufacturing practices that prioritize fabric quality and sustainability.

Rafiul; Miah, Ohid This thesis explores the design and development of outerwear, specifically jackets, constructed from a specific 3-layer fabric composition. The outer layer consists of 100% T2T Polyester, while the inner layer consists of 100% recycled polyester. The primary focus is on the mid-layer, which includes jute fabrics in two variants. The research focuses on the durability, durability and comfort of these materials as well as their performance characteristics in outerwear design. The thesis examines the viability of jute as a sustainable alternative for outerwear manufacturing through an iterative design process, prototype testing and performance testing. Key discoveries feature the impact of jute fabric type on jacket functionality, including breathability, and overall durability. For future advancements in outerwear design, the study provides insights into sustainable material choices and manufacturing methods.

It recommends creating a prototype of the clothing item that must meet the buyer's requirements. One of the most important procedures in the apparel business is sampling, which requires a strong performance to draw in customers. It's fascinating to observe that customers typically make a purchase after being pleased with the Samples' quality. The samples highlight the supplier's capacity. Only the provider and company will be identified by the customer as the source of the samples. Regardless of whether the samples are reasonably priced and of acceptable quality, customers should be politely encouraged to put a purchase. Therefore, it is essential that the examples demonstrate extraordinary ingenuity. The provider can estimate the amount of yarn required to create a fabric by creating samples, which aids in estimating the cost of the production problems. The supplier can also create prototypes and optimize processing parameters for large-scale manufacturing, which will help decrease bottlenecks of all kinds. The sample department, which works with the buyer at the border, is in charge of all these duties.

To develop the jacket first of all we design the jacket by studying the jacket design of different brand around the world. Then we made a draft design. To make the design we face different difficulties like- we are not professional designer, so we took help from a professional designer to create pattern of the draft design. Then we choose fabric, trimmings & accessories. After that we source the fabric, trimmings & accessories. To source the fabric, trimmings & accessories we took help of our senior brothers from different supplier. After that we did the sewing in the factory in which I am working. Then we also wash and finished the fabric in the factory. We found different difficulties in developing the jacket but by the grace of almighty and with the help of different industrialist person & our supervisor we have managed to overcome all the problems. At the end we managed to develop a jacket of mannequin. Thesis 2024-06-05T00:00:00Z
