| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 94 === According to the results of statistic analysis for textile defect claim cases in recent 12 years, streakiness ( barr’e, strip ) occupies the major proportion (about 65%). The cause of these defects included mainly yarn problem (about52%) and secondly weaving problem (about 25%). To further discuss the causes, it was found that the problems mainly came from improper batch (lot number) management and poor quality control. Therefore, improving batch (lot number) management and quality control was the key to prevent the streakiness defect. However, whenever the defect claim happened, people usually solved the dispute with former experience or mode. The problem disappeared for a while without total solution. Therefore, using systemic and objective method to study the defect causes was able to determine the causes of the defects accurately and efficiently.
This article studied the defects of finished fabrics and garments made by various fibers. Firstly, Digital Image Process Analyzer was used to observe the defect exteriors, as well as study their surface morphology and microstructure. According to the above conclusion, the analysis items were designed. The defect causes could be classified as material, yarn, weaving or dying and finishing by different analysis methods (such as appearance observation, physical analyses, chemical analyses and re-producing tests) and by knowledge or historical documents of dyeing and finishing. Herein the efficient and accurate methods for textile defect analyses were established.
