Abstract:In order to effectively control A1 yarn defects and ensure fabric quality and style，theconcept，importance and shape of A1 yarn defects are introduced in detail，the causes of A1 yarn defects are analyzed by observing the blackboard diagram of yarn defects.The causes of accidental short slubs are analyzed from raw materials，carding process，fore-spinning process and spinning process.The causes and mechanism of A1 yarn defects and the solution ideas of too many A1 yarn defects are analyzed with examples，and the main measures to solve A1 yarn defects are put forward.The factors influencing the level of A1 yarn defects are discussed from the aspects of spinning varieties，spinning mode，count，clearing process，semi-combed or not，and card clothing sharpness.The influence of card clothing sharpness on A1 yarn defects are mainly analyzed，and the main mechanism and solution measures are put forward.The results show that the quality and style of fabric surface are determined by A1 yarn defects，which is the biggest yarn defect on the fabric surface.The sharpness of card clothing has a great influence on A1 yarn defects，so the card clothing should be replaced in time to avoid the quality problems caused by card clothing without sharpness.The main measures to solve the A1 yarn defects are as follows:optimizing raw materials，ensuring appropriate process measures，cycle management on accessories and special parts，control short fibers，making full use of blackboard analysis method of A1 yarn defects，timely adjusting the temperature and humidity of workshop，and reasonably manageing suction box and dust filtration device.
