Data from: Evaluation of alternative-design cotton gin lint cleaning machines on fiber length uniformity index

This is USDA-ARS data from the publication: "Evaluation of Alternative-Design Cotton Gin Lint Cleaning Machines on Fiber Length Uniformity Index". The study was conducted in 2018 & 2019 with continued sample and data analysis through August 2023. Developing cotton ginning methods that improve fiber length uniformity index to levels that are compatible with the newer and more efficient spinning technologies would expand market share and increase the demand for cotton products and give U.S. cotton a competitive edge to synthetic fibers. Older studies on lint cleaning machines showed that the most widely used feed mechanism that places fiber on the cleaning cylinder damages fiber and reduces uniformity. The present study evaluates how conventional and experimental feed mechanisms affect uniformity. The lint cleaners were used with both saw and roller gin stands. Four diverse cotton cultivars from the Far West, Southwest, and Mid-South were used in the test. The data included gining process variables, raw seed cotton characteristics, raw lint High Volume Instrument (HVI), Advanced Fiber Information System (AFIS), and micro-dust and trash analyzer (MDTA3) measurements.

本数据集源自美国农业部农业研究服务局（USDA-ARS）的出版物《评估不同设计的棉籽加工机对纤维长度均匀性指数的影响》。该研究于2018年至2019年进行，并对样本及数据进行了持续的分析，直至2023年8月。开发能够提升纤维长度均匀性指数至与新型高效纺纱技术相匹配的棉籽加工方法，将扩大市场份额，增加棉产品需求，并为美国棉花在合成纤维竞争中获得优势。针对旧有棉籽清理机的研究表明，广泛使用的将纤维放置于清理滚筒的进料机制会损害纤维并降低其均匀性。本项研究旨在评估传统及实验性进料机制对纤维均匀性的影响。在实验中，采用了来自远西、西南和中西部的四种不同棉种，并使用锯齿和辊筒式棉籽加工机进行清理。数据包括加工过程中的变量、原棉籽特性、原棉高体积仪器（HVI）、高级纤维信息系统（AFIS）以及微尘和杂物分析仪（MDTA3）的测量结果。
