Abstract
Causes and preventing measures of yarn long thin places defect were discussed. Classification and characteristics of yarn long thin places defect were introduced. The causes were analyzed and related modified measures were put forward. It is considered that some problems should be solved as key,such as missing sliver in finish doubling,roving and sliver worse package,worse switch machine,higher doubling speed,too much sliver drawing,rubber-covered roll and apron winding fiber,worse draft gear meshing,worse guiding sliver tension and spinning suspended status et al. Defect existed in autoleveler device embossing roller sensor should be eliminated. Autoleveler delay time should be set correctly, width and pressure of embossing roller should be selected properly. Absolute measurement electronic yarn cleaner was adopted,finally better prevent effect can be made.关键词
