The regularity of yarn breakage after yarn forming is as follows:
1. The distribution of yarn breakage in doffing is that the small yarn has the most yarn breakage, the middle yarn has the least yarn breakage, and the large yarn has more yarn breakage than the middle yarn;
2、 After spinning, most of the broken ends occur in the spinning section (called the upper broken ends), and there are less broken ends between the steel ring and the bobbin (called the lower broken ends). However, when the steel ring and the steel ring are not matched properly, the vibration, wedging, wear, burning and flying of the steel ring will be caused, and the lower broken ends will be increased. The chance of decapitation in the aerosphere is rare;
3、 In normal production, most spindles have no broken ends in one doffing, but repeated broken ends appear on individual spindles;
4、 With the increase of ingot speed, the winding load and tension increase, and the end breakage generally increases;
5、 The guide hook and separator not only scrape the yarn, but also increase the breakage;
6、 Weight and material of steel ring;
7、 Unstable balloon shape will increase yarn breakage
