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 evenness measurement system, in particular to a yarn evenness measurement system based on the perimeter of the yarn section. Background technique [0002] Yarn evenness is an important index to evaluate yarn quality, it has an important influence on the appearance quality of fabrics, and it is an important factor in determining yarn grade and price. [0003] In the existing yarn unevenness measuring system, the methods currently commonly used are capacitive and photoelectric. The capacitive type measures yarn evenness data from the perspective of yarn quality control. The measured yarn density is essentially uneven. When it is used to predict the quality of the fabric, the predicted result will be found to have poor stability. This is because the quality of the fabric is mainly manifested in the visual effect of the finished product, which is closely related to the uneven app...
