(Daffodil International University, 2021-01-18) Mamun, Abdullah Al; Hossain, Md. Ismail; Mozumder, Sumon; Hossain, Md Kamrul
Ready-made garments are popular because of readily availability in the retail shops. Ready-made garments production requires standard measurement for each age group which depends on anthropometry. Measurement of ready-made garments varies on the anthropometry of a nation. The goal of the study was to develop a measurement chart and identify the size ratio and color preferences of both male and female young adults of Bangladeshi origin which is not in literature. A different point of measurement along with their heights of 409 males’ and 356 females’ young adult for the Tshirt was taken. Based on height, the male and female young adults were categorized into five sizes (S, M, L, XL, and XXL). It is found that the size ratio was around S: M: L: XL: XXL = 6: 32: 37: 18: 7 and 17: 30: 34: 13: 6 for male and female respectively. Proposed standard measurement of Length from highest point of shoulder, Centre front length, Armhole, Sleeve length, Neck width, Across shoulder, Half chest and Hem Width for size L for male is 68 cm, 63 cm, 23 cm, 19.5 cm, 21 cm, 44 cm, 49 cm and 49 cm for respectively. Preferences of color are quite wide of both male and female, most preferred color is blue among the male and black among the female. Two-third female adults preferred short sleeve t-shirt. Brands that are targeting to retail their Tshirt in the market of Bangladesh can use developed measurement sheets for the bulk production of T-shirt.
Ecological Impact of Effluents Discharged After Dyeing Cotton Knit Fabric With Reactive Dyes
(Daffodil International University, 2017-05-01) Swati, Sushama Saha; Mozumder, Sumon; Majumder, S.M.M.H.
This study mainly refers to investigate the environmental impact of textile effluents discharged after dyeing cotton knit fabric with eight different reactive shades. By this work it was possible to evaluate the influence of each shade on the present ecological system. Textile effluents generated after dyeing with eight shades were collected to analyze the ecological parameters, including acidity or alkalinity (pH), amount of dissolved oxygen (DO), total dissolved solids (TDS), temperature and visual colors. From the experimental data it can be said that the effluents produced from the dyeing process comprising primarily more alkalinity, less DO, more TDS, high temperature and nearly black color which have indubitably adverse effects on the biological system. Furthermore, all reactive dyes were not found to be equally responsible to affect the surroundings. Hence, this research work becomes vital to recommend a suitable reactive dye having low impact on the environment.
Evaluation of Personal Factors of Workers Affecting Productivity in RMG Sector in Bangladesh
(Tekstilec, 2019-09) Mozumder, Sumon; Chakraborty, Samit; Hoque, Md. Saiful
The readymade garment sector in Bangladesh is considered the backbone of earning foreign currency that includes a large number of workers and is mostly responsible for the economic growth of the country. Nevertheless, despite the remarkable growth of the RMG sector and its bright projection, impediments need to be overcome as well. Readymade garment industries in Bangladesh are currently facing some challenges to ensure fire safety and better work environment for garment workers. Apart from several technical factors, personal factors of workers, e.g. education, age, training, work experience and motivation, might also have a substantial impact on the increase in productivity to compete in the global export market. Thus, it was vital to observe the impacts personal factors of workers have on the productivity of readymade garment industries. This study enabled an identification of personal factors of workers which aff ect the productivity of readymade garment industries. The factors were examined through some critical analyses, e.g. hypothesis test, factor analysis and fishbone diagram analysis. After the investigation of empirical data, principal factors were identified and highlighted to improve the productivity in these industries.
