Includes bibliographical references and index. Coated fabrics. Since then, there have been new developments in the field of coated textiles. I have, therefore, taken the opportunity to present new areas of applications that have emerged in functional coatings. These are coatings with smart polymers and nanomaterials. Coatings with stimuli-sensitive polymers show much promise as intelligent textiles.

Nanomaterial coatings to produce soil-resistant fabrics have been successfully commercialized. The first edition of Coated Textiles: Principles and Applications was updated to include recent research trends, such as temperature-adaptable fabrics, silicone coating for air bag fabrics, health-care garments, intumescent coating, coating materials, and coating methods.

I am thankful to G. Mathur, L. Kandpal, D. Setua, B. Dutta, Priyanka Katiyar, and P. Khandelwal for useful discussion and assistance. I would also like to thank my wife Sutapa for her suggestions and encouragement. I developed an insight into the breadth of the subject during my long association with the Defense Materials and Stores Research and Development Establishment DMSRDE; Kanpur, India while working on the development of protective clothing and related equipment.

The opportunity to visit and work at several coating facilites has given me a feel for the complexity of the coated textile industry. The world production of coated fabrics used for defense alone, every year is in the order of a billion square meters. Extensive research is being done on a global basis, and many new products, such as breathable fabrics, thermochromic fabrics, and charcoal fabrics, are entering the market.

The subject is spread over a wide range of literature in polymer science and textile technology, with no single comprehensive book being available. The motivation to write this book was to fill this void and to create a general awareness of the subject.

This book is meant for the scientsts and technologists in academic institutions as well as in the coating and textile industry. It is one of the best equipped laboratories with various sophisticated analytical instruments. I am also grateful to G. His encouragement and help has been a source of inspiration. I am particularly thankful to my colleague N. Kasturia who first suggested that I write a book on the subject and for the help rendered at different stages in writing the book.

I am indebted to V. Tripathi, L. Kandpal, Anil Agrawal, T. Indushekhar, G. I also wish to acknowledge useful discussions and literature provided by A. Mody, Entremonde Polycoaters, Mumbai; M. Narain, Swastik Rubbers Pune; M. Above all, I am thankful to my wife Sutapa for her encouragement, inspiration, and valuable suggestions. Historically, the earliest recorded use of a coated textile is by the natives of Central and South America, who applied latex to a fabric to render it waterproof.

Other materials, like tar, rosin, and wax emulsions, have been used over the years to prepare water-resistant fabrics. Due to their vastly superior properties, rubber and other polymeric materials have become the preferred coatings. Today, coated fabrics are essentially polymer-coated textiles. Advances in polymer and textile technology have led to the phenomenal growth in the application of coated fabrics for many diverse end uses.

Coated fabrics find an important place among technical textiles and are one of the most important technological processes in modern industry. Textiles are made impermeable to fluids by two processes: coating and laminating.

Coating is the process of applying a viscous liquid fluid or formulated compound on a textile substrate. Laminating is the process of bonding together a preprepared polymer film or membrane with one or more textile substrates by adhesives, heat, or pressure. Fibrous materials are also used for reinforcing polymeric materials to form composites for use in tires, conveyor belts, hoses, and so forth. The scope of this book has been restricted to coated and laminated textiles and does not include discussion of polymer fiber composites.

Several methods of production are used to manufacture a wide range of coated or laminated fabrics. Broadly, they are spread coating, dip coating, melt coating, and lamination. They differ not only in the processing equipment used, but also in the form of polymeric materials used.

Thus, pastes or solutions are required for spread coating; solutions for dip coating; and solid polymers, such as powders, granules, and films, for melt coating and lamination. The basic stages involved in the processes are feeding the textile material from rolls under tension to a coating or laminating zone, passing coated fabric through an oven for volatalization of solvents, and curing and gelling and cooling of the fabric before final winding up. The final properties of a coated fabric depend on the type of polymer used and its formulation, the nature of the textile substrate, and the coating method employed.

The subject of coated textiles is thus interdisciplinary, requiring knowledge of polymer science, textile technology, and chemical engineering. The organization of this book is based on these considerations. Among the various polymers used for coating and laminating, four classes are mainly used for coating: rubber, polyvinyl chloride, polyurethane, and acrylics.

These polymeric materials are specifically formulated with additives and compounded into a paste suitable for coating. The production of a polymeric coating fluid is one of the most important tasks of the coating industry. The chemistry of these polymers, the additives used, and their processing for coating compounds and fluids is described in Chapter 1. Conventional solvent coatings are losing favor as they lead to environmental pollution.

The other areas covered in this chapter include various adhesive treatments for improved polymer—textile bonding and constituents of laminates used in automotive interiors i. The physical properties of a coated fabric are affected by the nature of the fiber and the construction of the textile substrate. The choice of the substrate depends on the application of the material. Discussed in Chapter 2 are the different fibers and their conversion into textile materials of various constructions used in the coating industry and fabric preparation prior to coating.

The coating and laminating methods employed by the industry are discussed in Chapter 3. Emphasis is placed primarily on the principles, rather than on the engineering aspects, of the machinery. Described in Chapter 4 are the changes that occur in the physical properties of a fabric when it is coated. A brief account of rheological factors affecting the coating is presented in Chapter 5.

Thus, the raw materials, the coating methods, and the properties of the end product are presented in a chronological sequence in this book. The large, ever-increasing variety of applications of coated fabrics is covered in the four subsequent chapters.

Protective clothing for foul weather is one of the major applications of coated fabrics. In Chapter 6, all types of coated fabrics for foul weather protection are discussed, with special emphasis on the developments in the field of waterproof breathable fabrics, and their applications, including in healthcare garments. Coated textiles used in synthetic leather, upholstery fabrics, fabric for fluid containers, back coating of carpets, architectural textiles, and automotive interiors are discussed in Chapter 7.

In various applications of coated fabrics, functional materials, such as fragrances, dyes, pigments, phase-change materials, or carbon, are applied either as such or enclosed as microcapsules on the textile materials with polymeric binders. These fabrics are finding use as camouflage nets, thermochromic fabrics, protective clothing for toxic chemical exposures, temperature-adaptable fabrics, and so forth. Such a special category of coated fabrics and intumescent coating is included in Chapter 8.

Metal coatings are finding newer uses in electromagnetic interference EMI and radio-frequency interference RFI shielding and radar-responsive fabrics. These fabrics are also discussed in this chapter. In Chapter 9, emerging areas of coating are discussed.

These areas include coating with smart polymers to produce intelligent textiles, and nanomaterials for providing some interesting properties to the fabric, such as soil resistance, improved dyeability, and so forth. The test methods pertaining to coated fabrics are discussed in Chapter References are given at the end of each chapter.

Properties of common polymers used for coating are separately provided in Appendix 1. And, a few typical formulations are given Appendix 2. He obtained his M. He worked in the fields of polymer science— characterization of polymers and blends by inverse gas chromatography, chemical process development, and special textile and clothing for the services.

He has been involved in the successful development and bulk production of clothing for extreme cold and chemical protection. The modern-day history of coating rubber on fabrics dates to , when the Scotsman Macintosh patented the first raincoat by sandwiching a layer of rubber between two layers of cloth. Since then, there have been great advances in rubber coated fabric technology. Coated fabrics are used for diverse applications.

Almost all types of rubbers are used for coating, but the discussion here will be restricted to those kinds that are more popular.
