The Fundamentals of Fibers Module presents basic information and terminology related to fiber identification, classification, production, and properties. It introduces the concept of polymerization and explains how the chemical composition and physical structure of a fiber influence its physical, chemical, and comfort properties. You will learn the generic names for fiber classification as defined by the Federal Trade Commission and be able to differentiate between natural and synthetic fibers. Physical, chemical, and thermal properties of many of the natural and synthetic fibers in use today are reported and described, as well as typical production procedures for synthetic fibers. The module will also enable you to be able to relate fiber properties to the resulting fabric properties in the end-use product.
The Texturing Fundamentals Module will give you an insight into the fundamentals of texturing. Content includes descriptions of the technology of the process, historical developments in technology, and types of texturing currently used are all discussed in detail. Important yarn property considerations, key processing steps and other key parameters for process control are included as well.
The Spun Yarn Manufacturing Module covers all the processing steps in the production of a short staple spun yarn, beginning with opening, cleaning, and blending and concluding with spinning and winding. The viewer will learn the key objectives of each process and gain knowledge of the many variables affecting yarn quality and production. All major types of short staple spun yarns are included along with their specific properties. Plied yarns and novelty yarns are also presented along with the major yarn numbering systems.
The Fundamentals of Warp Preparation Module discusses the importance of warp preparation as it relates to efficiency and quality in weaving and warp knitting. The types and applications of warping and slashing equipment are discussed, and the important variables of each are highlighted.
The Fundamentals of Warp Knitting Module will begin with some key information on warp beam formation and its relevance to the warp knitting machine. The key elements of tricot and raschel warp knitting machines will be presented along with the different types of fabrics that can be produced from these types of machines. Two bar fabrics, open-work fabrics, laying-in three and four bar fabrics, and two needle bar fabrics will be addressed. Examples of knit design notation for different warp knit fabrics will also be presented. Actual fabric swatches are viewed in normal and close-up range for many different knit designs. Videos and animations will enhance the viewer’s understanding and concept of warp knitting.
The Fundamentals of Weft Knitting Module begins by introducing weft knitting and warp knitting and then proceeds to elaborate on weft knitting. Key machine elements are presented along with important knitting terms and definitions. Single knit machinery and fabrics, double knit machinery and fabrics, and flat-bed knitting are discussed. Different types of knit loops and their influence on the fabric properties are also covered. Actual fabric swatches are viewed in normal and close-up range for many different knit designs.
The Weaving Fundamentals Module presents the basic motions of weaving, types of shedding, methods of filling insertion, woven fabric production calculations, basic woven design, and woven fabric properties. Derivatives of the basic weave designs are covered along with the different types of pile fabrics.
The Fundamentals of Nonwovens Module will discuss the major web forming technologies, with an overview of the processes involved. The technologies used for bonding with representative product types and advantages are explored.
The Fundamentals of Fabric Preparation Module is an overview of major technical processes used on fiber, yarn, or fabric to prepare them for subsequent processes such as dyeing, finishing, printing, and other apparel and non-apparel processes. Chemical and mechanical processes are discussed as related to function and technical procedures.
The Color and Color Properties Module covers information that will help you gain a better understanding of the variables that influence color perception. Current methods of shade matching and color measurement are presented. The relationship between perceived and acceptable color differences is discussed.
The Dyestuffs and Applications Module presents the objectives of dyeing and the keys to good quality dyeing. Dyestuff properties and methods of dyeing blends are discussed. Different types of dyeing equipment are reviewed along with advantages and disadvantages of each type.
The Printing Fundamentals Module presents methods of textile printing and describes the equipment employed with each method. Advantages and disadvantages of each method are also explained. An overview of digital ink jet printing is given with the current systems available.
The Chemical Finishing Module is a review of techniques used to apply chemical finishes to textile products. The more frequently used chemical finishes for textiles are discussed as related to function and chemistry involved.
The Mechanical Finishing Module is a review of mechanical processes applied to fabrics that add special surface effects and appearance value. The machines used for modifying textile fabric surfaces are explained.
