| dc.description.abstract | This study was designed to investigate assessment of warp yarn breakage on loom in case of Bahir Dar Textile Share Company by looking the current efficiency and production of loom. The study was carried out in 100% cotton warp yarn and six looms out of the sixty six air jet looms. Data was gathered through observation and interview. The frequency count, cumulative frequency count, cumulative percentages, and the pareto chart are the statistical methods used in analyzing the data. The study showed that Crossed end, Thin and Thick end, Contamination, Oil warp, Knots, Taped ends, Wrong drawing-in, Tension, Abrasion, Leno bobbin change, Chopped ends, and Fluff dirt or impurities are the major causes which influence warp yarn breakage on loom. From the findings it was concluded that the 88.10% of warp breakages from the total are produced by 50% of the causes that is knot (28.44%), thin and thick end (17.43%), and tension (14.67%), cross end (11.1%), abrasion (9.2%), and Fluff dirt or impurities (8.25%). Therefore it can be inferred that if Bahir Dar Textile Share Company able to solve the most frequently occurring causes, 88.10% of the warp yarn breakage problems will be eliminated. | en_US |
