| 摘 要: 织疵是衡量织造质量的关键指标。为了优化织造过程,减少织疵产生,首先分析了织造过程中导致织疵产生的影响因素,其次利用灰色关联分析法提取导致织疵产生的关键影响因素。实验和实际生产结果均表明,织机停车次数和停车时间对织疵产生数量的关联度较高,关联度均为0.83以上。同时,针对双纬、百脚和断经3类织疵进行分析,得出导致双纬产生的主要影响因素是经密和转速,导致百脚产生的主要影响因素是经停时间和转速,导致断经产生的主要影响因素是经停次数、打纬次数、停车时长等。 |

| Abstract: Woven defect is a key indicator of textile quality. To optimize the weaving process and reduce defect formation, this study first analyzes the factors that contribute to woven defects during weaving. Then, the grey correlation analysis method is used to extract the key factors that affect woven defect formation. Both experimental and actual production results demonstrate that the frequency and duration of loom stoppages exhibit a high correlation with the quantity of the woven defects, and the correlation coefficient is above 0.83. Furthermore, analysis of three types of woven defects—double picks, mis-picks, and broken ends—reveals that yarn density and roating speed are primary factors influencing double pick formation, stoppage time and roating speed are major factors for mis-pick formation, and factors such as stoppage frequency, filling insertion frequency, and stoppage duration primarily contribute to broken end formation. |
