Opis:
Denim industry is one of the emerging sectors in the world among all woven garments industry. The rapid changing monetary conditions like as global challenge, declining overall revenue, client interest for high quality item, variety of product and diminished lead–time and so on had a crucial impact on manufacturing plants. The interest for higher incentive at lower cost is expanding and to endure, clothing makers need to enhance their operation through-delivering right first-time quality and reduction of waste or reworks. Defects are the main concern in quality assurance of denim garments. Most of the defects are visualize in denim washing. This research emphasizes the cause effect and remedy of washing defects of denim garments. This research initiated by collecting quality inspected data of consecutive three months for the Whisker and Hand Brush process to have an overview of the defects of the washing plant and then analyzed the root causes and effects of the defects to provide a recommended solution both for Whisker and Hand Brush process on which standard operating procedure (SOP) is introduced to reduce the level of defects. After ensuring the standard operating procedure both for dry and wet process, quality inspected data was recorded for the following three months for Whisker and Hand Brush process. Finally, a significant level of defects is reduced in Whisker and Hand Brush process.

Opis:
Generally, the choice of cutting element used in brush cutters for brush-woods and grasses depends on the type of work on one hand and the size of the engine on the other. However, at the same time, the use of individually chosen cutting elements entails a certain risk of vibration resulting from their varying design and size, which has a big impact on comfort and working time, but most importantly on operator health. The aim of the study is a preliminary analysis of the dangers due to vibration of brush cutters and to determine how the choice of the cutting element affects the intensity of the vibrations emitted by the machine. Furthermore, one aim was to determine the daily vibration exposure, relative to an equivalent value of vibration, experienced by the device operator. This study involved four models of brush cutters with three machines of each model, differing in size (displacement and engine power) and equipped with six different cutting elements. A vibration acceleration test was carried out in accordance with the applicable PN-EN ISO 5349-1 and 2: 2004 and Directive 2002/44 / EC. An analysis of the obtained results leads to the conclusion that the examined professional brush cutters emit vibrations of such intensity that the daily exposure limit (5 m ∙ s-2) is exceeded more than twofold. One cannot directly determine the influence on vibration intensity by the type of cutting element or the exhaust, but it should be noted that use of a cutting unit as recommended by the manufacturer creates less harmful vibrations, especially when the engine runs at the nominal rotational speed. In order to minimize the risk due to vibrations from brush cutters, engines with a cylinder capacity below 45 cm3 are recommended to be equipped with trimmer heads and disk knives, while engines with over 50 cm3 should run with circular saws.
