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.

Cottons importance as a crop and as a textile fibre is still significant. However, its importance has been and will continue to be seriously challenged by the growth in consumption of man-made fibre, particularly polyester. This book is divided into three parts. The first part, covering seven chapters, describes the chemical and physical properties of cotton fibre. These chapters focus on the differences between cotton and polyester fibre properties, and highlight areas researchers will need to pursue to keep cotton competitive. Two lesser discussed properties receive attention: Cotton fibres wax layer and cotton celluloses glass transition temperature. The hydrophobic wax layer that protects cotton during mechanical processing and aids the dispersal of its seed by water, has been central in the development of the spinning technology used by cotton and polyester fibre alike. The wax provides lubrication between the fibre surface and the processing surfaces during opening, carding and spinning. The chapter on cotton celluloses glass transition temperature introduces the less appreciated concept that cottons cellulose can be plasticised at particular temperatures and moisture contents, wherein cottons mechanical properties, e.g. elongation to break, can be improved. The range of fibre property values and the variation found in cotton stand as markers for future researchers to improve by way of plant and crop management, breeding (including genetic modification), and chemical processing. Long standing objectives include longer, stronger and finer fibre, which all translate to better looking and performing yarn and fabric. However, properties that give cotton fabric improved resilience, drape and dyed-colour appearance also stand as objectives to improve cottons competitiveness. The second part of the book introduces uses of cotton that are less considered; cotton nonwovens, bandages impregnated with natural anti-microbial agents and cellulose aerogels are products with excellent potential, and deserve further research and development. Standard textile products are not discussed in this section. These are discussed in the third and final part of the book. The final four chapters focus on the current performance of cotton in different apparel and home furnishing markets, in the commodity marketplace, and in spinning and dyeing. These final chapters point to a challenging future for cotton if the industry and its researchers curtail their pursuit of better crop productivity, fibre quality, processing technology and product development.

Fibres usually experience tensile loads whether they are used for apparel or technical structures. Their form, which is long and fine, makes them some of the strongest materials available as well as very flexible. This book provides a concise and authoritative overview of tensile behaviour of a wide range of both natural and synthetic fibres used both in textiles and high performance materials.After preliminary chapters that introduce the reader to tensile properties, failure and testing of fibres, the book is split into two parts. Part one examines tensile properties and failure of natural fibres, such as cotton, hemp, wool and silk. Part two discusses the tensile properties and failure of synthetic fibres ranging from polyamide, polyester and polyethylene fibres to carbon fibres. Many chapters also provide a general background to the fibre, including the manufacture, microstructure, factors that affect tensile properties as well as methods to improve tensile failure.With its distinguished editor and array of international contributors, Handbook of tensile properties of textile and technical fibres is an important reference for fibre scientists, textile technologists and engineers, as well as those in academia. - Provides an overview of tensile behaviour of a wide range of both natural and synthetic fibres - Examines tensile characterisitics, tensile failure of textiles fibres and factors that affect tensile properties - Discusses mircostructures and each type of fibre from manufacture to finished product

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.
