Abstract

The invention relates to a yarn evenness measuring system based on yarn section perimeter. Nonuniform yarn appearance evenness is understood from the perspective of the relation between yarn and fabric. The technology is based on an elliptical yarn section model, a double-axial CCD camera is used for obtaining yarn images in two directions perpendicular to each other, and the novel yarn evenness measuring system is obtained. The system can effectively reduce influences of irregular sections of yarn, yarn hairiness and the like on yarn appearance evenness measuring, yarn appearance evenness measuring is barely influenced by temperature, humidity, atmosphere state and other outside conditions, yarn blending state, yarn optical property difference and the like. Influences of yarn sections on yarn evenness and the deformation relation from yarn to fabric are fully taken into consideration, evaluation of yarn appearance evenness and fabric appearance uniformity is easy, and compared with existing instruments, the system is more applicable to the field of yarn appearance quality objective evaluation and fabric appearance quality prediction.

Description

technical field [0001] The invention belongs to the field of yarn quality detection, and relates to a yarn thread evenness measurement system, in particular to a yarn thread evenness measurement system based on the circumference of a yarn section. Background technique [0002] Yarn dryness evenness is an important indicator for evaluating yarn quality, has an important impact on the appearance quality of fabrics, and is an important factor in determining yarn grade and price. [0003] In the existing yarn unevenness measurement system, the commonly used methods are capacitive and photoelectric. The capacitive method measures the yarn dryness data from the perspective of yarn quality control, and what it measures is essentially the unevenness of the yarn linear density. When it is used to predict the fabric quality, it will be found that the predicted results have poor stability. This is because the quality of the fabric is mainly manifested in the visual effect of the finis...
