of cotton fibers. These algorithms involve a sequence of pixel manipulations in order to resolve problems present in the image for a better analysis. Then, we measure a set of cotton geometric parameters to define newest factors of cotton maturity. BACKGROUND There is two ways for determining mature and immature cotton fibers in a given sample. and fineness, and maturity and fineness) has been observed. There is a need to model the relation-ships between these variables to understand the changes in R2. The objective of this study was to develop and compare models between micronaire, fineness, and maturity in terms of the cross-sec-tional dimensions of wall thickness and Size: KB. Previous researchers established a set of reference cottons with known fiber maturity and linear density (fineness) values based on the analysis of a large number of individual transverse fiber cro Cited by: 3.

Different methods of testing cotton for fineness and maturity are reviewed and the precautions to be taken to get accurate results are discussed. Merits and limitations of the methods are indicated. Relationship between the values from different. Maturity and micronaire value. Maturity of cotton is an important property; the higher its maturity the stronger and thicker the fibre or higher its linear density which is usually related to better dyeability, ease of processing and ultimate quality of the product. A rapid measurement for cotton breeders of maturity and fineness from developing and mature fibers.

fineness and maturity. This paper reports on the use of a reference technique for measuring cotton maturity, based on image analysis of thin fiber sections to develop a set of standard calibration cottons having a wide range of fineness and maturity values. We are working closely with several cotton geneticists/breeders. Fiber Fineness is one the most important fiber characteristics. The Fiber Fineness determines how many fibers are present in the cross-section of a yarn of given thickness. Minimum thirty fibers are needed in the yarn cross-section but there are usually hundred. For almost all new spinning process one hundred is approximately the lower limit. Fiber fineness: The fiber fineness is expressed in weight per unit length or length per weight. According to “Textile Institute”, the fineness of cotton, silk and manufactured fibers is usually expressed in terms of average linear density. Fiber fineness can be measured by the following method: Air flow method, Gravimetric method. The method of cotton fineness assessment by CottonScan is based on a direct method of measuring the total length of a known mass of fiber snippets to directly calculate the mass per unit length (fineness). The SiroMat™ instrument determines a fiber’s maturity based on fiber colors when viewed under a polarised light microscope.
