Imagine technical textiles that filter hazardous waste, bacteria, and parasites from drinking wa- ter; that keep pets and livestock safer and healthier; that keep roadbeds smooth longer; that help wounds heal; and that enable astronauts to work outside their spacecraft! Imagine fibers so tiny they are sized by nanometers (1 (cid:2)10(cid:3)9m) or so large that they can cut through plant stems, or fibers that are based on research about spider webs! You will learn about all these amazing textiles, innovative research in the industry. The majority of the text is devoted to basic information about textile materials, with an em- (a) Woven fabric phasis on fibers, yarns, fabric construction, finishes, and coloration. These interdependent el- Fiber ements found in most textiles contribute to the beauty or aesthetics, durability, care, cost, Finished fabric Yarn appearance retention, safety, function, and comfort of textile products. Much of the terminology used may be new to students, and many facts must be memo- rized. It takes time and effort to understand and recognize the fine differences among fibers, yarn and fabric structures, and finishes and coloration methods. You will have to examine many fabrics closely in order to develop this ability. Often, a single term is used to describe a wide range of fabrics. For example, velvet can be produced by knitting, weaving, tufting, and flock- F a ing. Woven velvet is used for skirts and dresses. Heavier weight woven velvets and warp-knit b ric velvets are used for upholstery. Flocked and tufted velvet are less expensive and used for less expensive upholstered furniture. To apply a knowledge of textiles, an understanding of the basics is essential. The empha- sis is on fundamental concepts and commercially significant fibers, yarn and fabric types, fin- ishes, coloration techniques, and production methods. Principles of textile production are included to help the student develop a better understanding of, and appreciation for, the tex- Unfinished fabric tile industry. Because of the quantity of information included, it will be a useful resource for in- (b) Knit fabric dividuals seeking careers in the global textile complex. Fiber Finished fabric Yarn Textiles and Textile Products But what are textiles? To know what textiles are and to understand textiles, several basic terms F must be defined: a b ric TextileA term originally applied only to woven fabrics, now generally applied to any flexible material that is composed of thin films of polymers or of fibers, yarns, or fabrics or products made of films, fibers, yarns, or fabrics. Polymer A very large molecule made by connecting many small molecules together. Almost all fibers are polymers made of organic materials, but some polymers are formed into thin films and used as textiles. For example, vinyl upholstery is a film, often applied to a more traditional textile knit or woven material for added durability. FiberAny substance, natural or manufactured, with a high length-to-width ratio possessing Unfinished fabric suitable characteristics for being processed into fabric; the smallest component, hairlike in Figure 1 The components nature, that can be separated from a fabric. Fibers can be absorbent (like cotton and of a fabric:fiber,yarn,structure, rayon), stretchy (like spandex), warm and bulky (like wool), or very strong and abrasion and finish. resistant (like nylon and polyester). (See Figure 1.) 4 introduction YarnAn assemblage of fibers that is twisted or laid together so as to form a continuous strand that can be made into a textile fabric. Yarns can be used to make a fabric that is smooth and slick like satin or soft and fuzzy like brushed denim. (See Figure 1.) FabricA flexible planar substance constructed from solutions, fibers, yarns, or fabrics, in any combination. (See Figure 1.) Fabrics range from lightweight and sheer chiffon scarves to heavy and sturdy denim to rigid and firm carpeting to technical products. (See Figures 2and 3.) Gray goods (grey or greige goods)Any fabric that has not been finished. Consumers rarely see gray goods, except for home sewers and quilters who may work with muslin.

While smart textiles are an area undergoing rapid change, many new smart areprocessed into yarns and woven or textiles are of interest to government agencies, the military, and consumers. Smart textiles deliver knit into fabrics. Coloration and finishing medication in slow controlled doses, monitor pulse and body temperature, promote safety with add value, enhance appearance, sensors that identify seat occupancy in vehicles, and keep wearers comfortable by promoting heat or improve performance. loss in warm weather and minimizing heat loss in cooler weather. In the future, some smart textiles may clean themselves. Research in its early stages has found chemicals that can be applied to the surface of fabrics to break down soil and kill microorganisms that cause odor. Smart textiles also offer the potential for reducing design and product piracy and counterfeit products. Technicalor industrial textilesinclude a broad range of materials that are widely used in special applications of a technical nature and that are generally not considered apparel or in- teriors. Table 1lists examples of technical textiles. Technical textiles contribute to quality of life. For example, the automotive industry uses textiles for tire cords for a durable tire that produces a comfortable ride; seat upholstery and carpeting for comfort, style, and easy care; head liners and window runners for noise reduction and a finished interior; seat belts and shoulder har- nesses for safety; reinforcement fibers in molded plastic parts to reduce weight and cost; and fan belts, gaskets, and seals to improve function and efficiency. Some textiles are encountered every day while others are never directly used or seen by most people. Everyday textile products include apparel(clothing and fashion accessories like bags and shoes made from flexible materials), interior textiles(including upholstered furniture, carpets and rugs, wall coverings, draperies and curtains, table linens, and towels and bed linens; also known as interior furnishings or home fashions), and technical and industrial textiles found in the home like toothbrushes and bandages and wraps to immobilize or support wrists and ankles in first aid kits, and in the car (seat belts, trunk liners, and gaskets and belts in the en- gine). Technical textiles include fabrics that reduce environmental damage (woven and nonwoven landscape erosion control fabrics) and protect other buildings and pedestrians during demolition of buildings (woven and nonwoven demolition screen fabrics). Medical textiles include warp knit replacement veins, graphite fibers to lubricate replacement joints, impermeable gloves and bandages that protect against infection, and filter membranes in artificial kidney machines. 5
