摘　　要：纱线内部纤维的分布以及转移规律是纱线研究的热点。同步辐射三维显微CT成像技术(μ-XCT)具有穿透性强、分辨率高等优势,可以清晰地展示被检测物体的内部结构状况。本文基于同步辐射三维显微CT成像技术对一种棉纱(转杯纺棉纱)进行扫描,然后采用Avizo中AI辅助分割模块进行三维构建和可视化表征。结果表明:借助同步辐射CT成像技术实现亚微米分辨率棉纱的三维显微成像表征,可以获取纱的结构特征以及纤维在纱中纤维转移特征。这促进了人们对纱线结构和性能的全面深入理解,为优化棉纱生产、提高棉纱质量和性能提供了宝贵的信息。The distribution and transfer behavior of fibers within yarns has garnered significant research interest.Synchrotron radiation three-dimensional(3D)micro X-ray computed tomography(μ-XCT)is known for its strong penetration and high resolution and is used to visualize the internal structures of objects.In this study,a cotton yarn(ring-spun cotton yarn)was scanned,then reconstructed using 3D printing,visualized,and trimmed using the AI-assisted segmentation module in the Avizo software.The results showed that the sub-micrometer-resolution 3D microscopic imaging of cotton yarn could be achieved.This can be used to acquire the structural features of the yarn and its fiber transfer characteristics.A comprehensive understanding of the structure and performance of yarns was developed,providing valuable information for optimizing cotton yarn production and improving yarn quality and performance.
