Abstract
Background: Fineness and maturity are major quality characteristics of cotton fibers which are directly related to yarn and end product value. As a fact, fine and mature cotton fibers are the most and required by spinners. Thus, there is a need for an accurate and rapid method for measuring cotton fiber fineness and maturity characters. Objectives: This present study was conducted to explore the possibility of utilizing the data of “HVI” to estimate the fiber fineness and maturity parameters of Egyptian cotton, corresponding to the same parameters provided by both of “Micromat” instrument and Image Analyzer. Methodology: To achieve the objectives 15 of Egyptian genotypes produced by Cotton Research Institute, Giza, Egypt, as well as two of Upland cotton samples from Sudan were used in this study during 2012 season. The samples were tested using the HVI, Micromat and the Image Analyzer instruments. Results: Data of the degree of thickening, area of secondary cell wall and perimeter showed no significant difference between its means, excellent correlation and determining factor between both of the Image analysis data and the data extracted from the equation used for HVI software. Conclusion: Thus, it could be easy to add new characters to the HVI output data and simulate both of the Micromat and Image analyzer instruments successfully. These equations will save time, efforts, labors and testing costs.
