It has evolved to produce a fabric that has become one of the most effective natural forms of all-weather protection known to man.In Bangladesh the use of wool fibre is very limited in respect of end use. Wool associated products are manufactured with imported wool fibre. In this study after collecting wool fibre from the local source of dhaka the fibres were then carbonized. The carbonizing process was carried out in factory environment. The fibre length , microscopic view were observed in the study . It was evident the carbonized wool were slightly damaged during carbonization. We got the results from the carbonizing wool, microscopic view , fiber length. We found the length of our collected wool test to be 1.8 inch. We can use wool of this length for many purposes. In our test, we did not get the correct length due to some machine fault and man fault. In future anyone want work or research in this topic this paper will help them.

Towhidul; Islam, Md. Razzakul Natural dyes having very less impact on environment than synthetic dyes are inspiring to find out different cheap, biodegradable, non-toxic, and non-allergenic sources of color. The wastages found in kitchen from different vegetables, fruits and others usages can be one of those sources. Our work is structured with natural dyes extraction from different kitchen wastages and dyeing cotton and polyester fabrics with the extracted dyes liquor. Dyes were extracted from some common kitchen wastages like beet root peel, banana skin, pomegranate skin, onion peel and used tea by aqueous extraction method. After easy dyeing process with mordants, color fastness properties like rubbing fastness, wash fastness and perspiration fastness properties were evaluated using standards testing methods. The color fastness properties are satisfactory for most of the samples dyed by pomegranate skin, onion peel and used tea. Beet root peel and banana skin provided poor to average color fastness properties.

Rosul, Md. Golam; Morshed, Rathwane; Hossain, Ass-oat; Safa, Farsin; Islam, Touhidul Changeover time reduction is a vital issue in the industries and lot of tools has been used for this purpose. In this research work the main aim is to prepare a sustainable format for the purpose of reducing changeover time through cloud computing system. To execute the research PDCA (Plan, Do, Check, Act) methodology has been implemented. A huge amount of data related to product specification and production process will be collected to prepare the sustainable format of changeover board. A format is created that generates automated emails, that greatly enhance the result of the output. It greatly reduces manufacturing time and enhances worker initiative, which improves labor efficiency and elevates production rate. Before the preparation and after the implementation of changeover board collaboration will be done with the factory personnel. The required amendments will be done after the collaboration with the factory personnel. Finally, the corrected version of changeover board will manage to reduce changeover time at a great extent and increase the productive time in the industry.

Beta Vulgaris was used as a bio-based dye to color cotton fabrics that were part of this research project. In the dyeing tests, metal salts, including Alum Al2 (SO4)3, Copper sulphate (CuSO4), Zinc Sulphate (ZnSO4), and Ferrous Sulfate (FeSO4), were utilized in an effort to strengthen the coloring process. We also examined the color fastness capabilities of all of the colored samples by subjecting them to various conditions such as washing, rubbing, and perspiration. The outcomes match one's expectations. The findings of the dying process and the experiments indicated that the performance of dye ability of the cotton fibers with Beta Vulgaris may be considerably influenced by the type of mordant that was used and the manner that was used to apply it.
