Fusing multifocus images for yarn hairiness measurement
Yarn hairiness has been an important indication of yarn quality that affects weaving production and fabric appearance. In addition to many dedicated instruments, various image analysis systems have been adopted to measure yarn hairiness for potential values of high accuracy and low cost. However, there is a common problem in acquiring yarn images; that is, hairy fibers protruding beyond the dep...
متن کاملYarn Hairiness Determination Using Image Processing
Yarn hairiness is one of the key parameters influencing the quality of yarn.It is observed that yarn quality has been deduced based on yarn length and diameter only. But these parameters do not provide much information about yarn quality. Thus it is proposed to derive more yarn quality parameters like yarn hairiness, uniformity of yarn and its thickness. In textile industry, image processing is...
متن کاملStudy on Sirospunning System to Reduce the Hairiness of Yarn
The twisting process of Sirospunning and Ringspunning was compared and analyzed as to the phenomenon that Sirospunning decreases yarn hairiness. It can be obtained from the analysis of geometrical model that more hairiness is twisted into the yarns and the amount of apparent hairiness is reduced through its special twisting. It can be calculated that when the count is equal Sirospunning can red...
متن کاملA Controlled Experiment on Yarn Hairiness and Fabric Pilling
This study is focused on the hairiness of worsted wool yarns and how it affects the pilling propensity of knitted wool fabrics. Conventional worsted ring spun yarns are compared with comparable Solospun yarns and yarns modified with a hairiness reducing air nozzle in the winding process (JetWind). Measurements of yarn hairiness (S3) on the Zweigle G565 hairiness meter shows a reduction in the S...
