The broader impact/commercial potential of this I-Corps project is in addressing the need in the domestic cotton industry for a better fiber length measurement. Yarn imperfections caused by excessive within sample variation in cotton fiber length result in discounts and lost profits for spinning mills. However, current fiber length measurements used to market cotton fiber do not adequately capture within sample variation in fiber length needed to identify cotton bales that may cause problems. As a result, cotton farmers are often producing the highest quality cotton but the market is not responding with premiums commensurate with their efforts. This technology allows farmers to focus on quality by providing a way for them to differentiate their product in the market for increased profit. Seed companies can use this technology to screen their germplasm for excessive within sample variation in fiber length. This is an important step toward developing elite cotton varieties and biotechnologies for domestic cotton farmers.This I-Corps project further develops a new algorithm that provides a fast and accurate measurement of within sample variation in cotton fiber length. The technology is based on the fibrograph method, where a fibrogram curve is generated that characterizes the attenuation of light through a randomly caught beard of fibers. The technology was evaluated on samples that were selected to represent a wide range of phenotypic variation, and a set of samples that was produced and harvested under commercial conditions. Fiber length measurements based this technology were able to better explain variation in yarn tensile properties and yarn imperfections when compared against length measurements currently used in the industry. In addition, this technology is faster and less expensive than existing instruments designed to help spinning mills measure within sample variation in fiber length.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个i-Corps项目的更广泛的影响/商业潜力在于满足国内棉花行业对更好的纤维长度测量的需求。棉纤维长度在样品内变化过大而造成的纱线瑕疵，会给纺纱厂带来折扣和利润损失。然而，目前用于销售棉纤维的纤维长度测量不能在样本内充分捕捉纤维长度的变化，这是识别可能导致问题的棉包所需的。其结果是，棉农往往生产出最高质量的棉花，但市场并没有对与他们的努力相称的溢价做出反应。这项技术使农民能够专注于质量，为他们提供了一种在市场上差异化产品以增加利润的方法。种子公司可以使用这项技术来筛选他们的种质，以寻找样本内纤维长度变异过大的情况。这是为国内棉农开发优秀棉花品种和生物技术的重要一步。i-Corps项目进一步开发了一种新的算法，可以快速准确地测量棉纤维长度在样本内的变化。这项技术基于纤维图方法，其中生成了一条纤维图曲线，该曲线表征了光通过随机捕捉的纤维胡须的衰减。对这项技术进行了评估，选择了代表广泛表型变异的样本，以及在商业条件下生产和收获的一组样本。与目前行业中使用的长度测量相比，基于该技术的纤维长度测量能够更好地解释纱线拉伸性能和纱线瑕疵的变化。此外，这项技术比现有的仪器更快、更便宜，这些仪器旨在帮助纺纱厂测量纤维长度的样本变化范围。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
