This book was released on 2018-09-08 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Determining Fiber-Length Distribution of Cotton by Electrical Resistance Measurements The basic importance of length measurement of cotton fibers has never been greater than it is today, according to the National Cotton Council.2 In particular, there has been an increasing need for precise determination of the distribution of fiber lengths within a sample of cotton. These determinations allow cotton - mill operators and merchants to select the best length of cotton available for their particular needs. Length - distribution data are also of great importance for studies in genetics, breeding, and cultural prae tices related to the cotton plant. Mechanically harvested cotton requires additional cleaning to produce samples equal in appearance to samples of handpicked cotton. This additional cleaning increases the risk of fiber damage such as fiber breakage, especially if accompanied by excessive drying. The detection of such damage is becoming increasingly important to farmers and buyers, as well as to spinners and researchers.

Book excerpt: The price of cotton is dictated by quality and the most significant factor of contributing to the fiber quality is the length distribution of the fibers contained within the population. Therefore it is of importance to accurately and repeatably measure the length of fibers within a population so that it is graded properly. Current methods are inadequate and thus prior work focused on designing a machine to directly measure individual cotton fibers using digital imaging. The current work begins with the evaluation of the effectiveness of the digital imaging machine. The machine was evaluated and sources of error identified. Modifications were implemented in an attempt to improve the error. After multiple modifications with little success an entirely new design was conceptualized. The new design aimed to eliminate all major sources of error with the existing machine while not creating new sources of error. The new design is discussed and the results are compared to those obtained by the original imaging machine. The new machine was better able to accurately measure the length of cut length fibers. The variation between fibers within a sample and entire samples of cut length fiber was significantly decreased when compared to the variation of the previous system.

Book excerpt: This research studied the accuracy and feasibility of cotton fiber length measurement by image processing as an alternative to existing systems. Current systems have some weaknesses especially in Short Fiber Content (SFC) determination, which is becoming an important length parameter in industry. Seventy-two treatments of five factors were analyzed for length and time measurements by our own computer program. The factors are: Sample preparation (without fiber crossover and with fiber crossover), lighting (backlighting and frontlighting), resolution (37-micron, 57-micron, 106-micron, and 185-micron), preprocessing (4-neighborhood and 8-neighborhood), and processing (outlining, thinning, and adding broken skeletons). The best results in terms of accuracy, precision and analysis time for images without fiber crossovers were: 106-micron resolution with frontlighting using an 8-neighborhood thresholding algorithm and using an outline algorithm for length determination. With fiber crossovers, 57-micron resolution with backlighting using an 8-neighborhood thresholding algorithm and using a thinning algorithm combined with an adding algorithm for combining broken skeletons. Using the above conditions, 1775 area can be analyzed using our current equipment in 15 seconds. In the case of images with crossovers, only 117 can be analyzed in 15 seconds. This research demonstrates that successful sample preparation without fiber crossovers would create the best fiber length measurement technique, however with fiber crossovers the system efficiency has been proven as well.

Available in PDF, EPUB and Kindle. Book excerpt: Cotton fiber is the most important natural fiber used in the textile industry. The physical structure and chemical compositions of cotton fibers have been extensively studied. Newer high speed spinning instruments are being deployed around the world that demand longer, stronger and finer fibers. Consequently, genetic improvement in fiber quality has been stressed. With improvement in fiber quality has come the realization that further fiber improvement will require a better understanding of fiber development and biology. As a consequence, cotton fiber developmental biology, genetics and genomics have become focal points in the cotton research community. As the longest single-celled plant hair, cotton fiber has been used as an experiment model to study trichome initiation and elongation in plants. This book provides a comprehensive update on cotton fiber physics, chemistry and biology that form the three sections of the book. In the physics section, the physical structure of cotton fiber is first illustrated in great detail. Then a suite of fiber properties and their measuring methods are described. The pros and cons of each method are outlined. New methods to measure physical properties of single fiber and young developing fibers are included. In the chemistry section, the chemical compositions of cotton fibers are described in detail. This knowledge is necessary for efficient modification of cotton fibers for better and broader utilization. The advancement in cotton fiber modification using chemical and enzymatic methods opened new ways to utilize cotton fibers. In the biology section, the book first introduces the utilization of naturally occurring color cottons. Color cottons possess unique attributes such as better fire retardant ability. Advancement in understanding fiber color genetics and biochemical pathways and new utilization of color cottons are discussed. Recent technological advancements in molecular biology and genomics have enabled us to study fiber development in great depth. Many genes and quantitative trait loci related to fiber quality attributes have been identified and genetically mapped. Some of these genes and QTLs are being used in breeding. Progresses in cotton fiber improvement using breeding and biotechnology are discussed in the last chapter. This book serves as a reference for researchers, students, processors, and regulators who either conduct research in cotton fiber improvement or utilize cotton fibers.

Book excerpt: The market value of cotton is largely determined by a subjective evaluation of a limited number of quality parameters such as: Grade, Length, and Fineness. Cotton is classed to determine its grade, which indicates the spinning value and utility, and hence the market value or price. Farmers are interested in the classification of cotton by grade to evaluate production, harvesting, and ginning practices, in order to market their cotton profitably, on the other hand, merchants could efficiently buy and sell cotton in accordance with grade.The world wide spread of High Volume Instrument (HVI) testing systems, with their ability to provide rapid and economical measurements of the most important cotton fiber properties, has stimulated efforts to obtain the maximum benefits from these systems.There is a direct correlation between the quality of raw material and the end products. The lower quality of cotton fibers means the lower quality of yarn produced from such a raw material. High quality cotton blends are superior with respect to properties such as length, fineness, elongation, and brightness, sufficiently mature and without any trash particles and displaying a high capacity of spinning consistency.It's worth to say that we are in a need for the visual classification, as it is suitable for application in the local marketing system, as producer sells seed cotton. While using the fiber quality index (FQI) comes in a following step, as it is suitable for application in the international marketing system, as traders sells lint cotton.The present investigations are subjected to study the relationship between the HVI fiber properties and yarn quality to evaluate the actual value of the cotton fibers. Besides determining the relative importance or contribution percentage of each fiber property to the yarn quality and suggesting a statistical approach for calculating a Fiber Quality Index (FQI). In Addition to study the effect of variety, location and seed cotton level on the fiber quality index of the Egyptian cotton.Also to clarify the effect of both genotype and environment on the HVI cotton fiber properties of some Egyptian cotton varieties and its yarn quality. Besides, introducing some new variables fiber quality index (FQI) for determining the actual value of cotton using the HVI fiber properties. This FQI defined the desirable properties of cotton that allow the production of the best quality yarn in particular manufacturing system.New FQIs (Fiber Quality Indices) equations, Lea Product value predicting equation, and a New Leaf Grade equation was obtained, beside studying Card Waste (%) effect on color attributes.
