Abstract

This study was conducted to explore new opportunities to deliver accurate and reliable measurements in terms of fibre length distribution. Ten samples of cotton fibre with a wide range of mean length ranging from 24.28 to 32.38 mm and a short fibre content (SFC%) ranging from 7.3% to 17.4% were selected. In Part 1 of the study, the fibre was tested using the more traditional methods, which include HVI, AFIS and SWA. There were strong positive and significant relationships between the various fibre length measurements provided by the three methods. Although there were moderate relationships between SFC% as measured by HVI and AFIS, the relationship with SWA was low and negative. In Part 2 of the study, cotton sliver, from the above-mentioned fibre was tested on AFIS, Almeter , Fibrotest and OFDA 4000. There were also moderate and strong positive relationships between all the length measurements, including SFC% as measured by AFIS, Almeter, Fibrotest and OFDA 4000.

摘要

进行这项研究是为了探索在纤维长度分布方面提供准确和可靠测量的新机会。选择了平均长度范围为 24.28 至 32.38 毫米且短纤维含量 (SFC%) 范围为 7.3% 至 17.4% 的十个棉纤维样品。在研究的第 1 部分中，使用更传统的方法对光纤进行了测试，包括 HVI、AFIS 和 SWA。三种方法提供的各种纤维长度测量值之间存在很强的正相关关系。尽管 HVI 和 AFIS 测量的 SFC% 之间存在中等关系，但与 SWA 的关系较低且为负。在研究的第 2 部分中，来自上述纤维的棉条在 AFIS、Almeter、Fibrotest 和 OFDA 4000 上进行了测试。
