The use of distinctive colourants and finishes has a significant impact on the aesthetic appeal and functionality of technical textiles. Advances in the textile chemical industry facilitate production of diverse desirable properties, and are therefore of great interest in the production of textile products with enhanced performance characteristics. Drawing on key research, Advances in the dyeing and finishing of technical textiles details important advances in this field and outlines their development for a range of applications. Part one reviews advances in dyes and colourants, including chromic materials, optical effect pigments and microencapsulated colourants for technical textile applications. Other types of functional dyes considered include UV- absorbent, anti-microbial and water-repellent dyes. Regulations relating to the use of textile dyes are discussed before part two goes on to investigate such advances in finishing techniques as mechanical finishing, softening treatments and the use of enzymes. Surfactants, Inkjet printing of technical textiles and functional finishes to improve the comfort and protection of apparel are also explored. The use of nanotechnology in producing hydrophobic, super-hydrophobic and antimicrobial finishes is dealt with alongside coating and lamination techniques, before the book concludes with a discussion of speciality polymers for the finishing of technical textiles. With its distinguished editor and international team of expert contributors, Advances in the dyeing and finishing of technical textiles is a comprehensive guide for all those involved in the development, production and application of technical textiles, including textile chemists, colour technologists, colour quality inspectors, product developers and textile finishers. Discusses important advances in the textile chemical industry Considers developments in various dyes and colourants used in the industry, including water repellent, functional and anti-microbial dyes Chapters also examine advances in finishing techniques, the use of nanotechnology and speciality polymers in technical textiles

Textiles that are primarily used for their performance or functional properties and not for their appearance or aesthetics are known as technical textiles. The industrial fabrics that are used for various industrial applications are also classified as technical textiles. Textile processing involves the use of different types of speciality chemicals during the course of conversion of textiles into finished fabrics, a large number of which generally are surface active agents, so much so that textile speciality chemicals are considered synonymous with surface active agents. This chapter discusses the theory of surface tension, the classification of surfactants, and the raw materials used and their end-use application on technical textiles along with their chemical structures. Natural surfactants along with their chemistries are also discussed in the chapter. Highlights concerning smart surfactants and Biodegradable surfactants are also mentioned.

Touch or handle is an important aspect of textile evaluation. Technical textiles, in particular, are subjected to several processing and finishing operations which may make the material harsh or brittle. Softening is, therefore, an important last-step process requirement in such applications. Selection of a suitable compatible softening treatment is critical, otherwise the softener itself may impair the functionality of a technical product. This chapter discusses the mechanical, enzymatic and chemical methods of softening available to a processor, with a greater focus on the chemical methods as they are the most frequently used. Specific requirements of softening technical textiles such as medical, easy care, flame retardant, stain repellent and stain resistant and printed textiles are discussed. The effects of softener application on the physical properties, colour, whiteness, handle and flammability of textiles are also included. The environmental impact of softeners and the objective methods used for measurement of softness are also discussed in detail.

Mechanical finishing is the process that alters the hand, appearance and performance of textiles. Technical textiles are products manufactured primarily with performance, rather than aesthetics, in mind. This chapter reviews the various mechanical finishing processes that technical textile products will endure. Applications of the mechanically finished fabric in technical textiles, and the mechanical finishing technologies adopted in the latest machines, are discussed in this chapter.

This chapter discusses the principles of chromic materials as applied to textiles. The most important chromic phenomena – thermochromism, photochromism, ionochromism and electrochromism – are dealt with in individual sections, each providing a description of the physicochemical principles underlying the colour changes and a discussion of the molecular structures of the most important colorant classes. An overview of the main non-textile applications of chromic materials sets the scene for more detailed discussion of progress through ongoing research towards technical and smart textile applications. The chapter concludes with informed speculation on likely future trends in the development of products based on chromic textiles.

In this chapter, the use of enzymatic techniques for the finishing of technical textiles is discussed. The chapter begins by discussing the various types of enzymes used in textile finishing. It then reviews the enzymatic processing of textiles like cotton, wool, silk and synthetics, followed by their application methods. Recent developments in assessment techniques and future trends are also briefly discussed.

Abstract: This chapter highlights the most significant advances reported towards the use of speciality polymers for finishing of technical textiles. The chapter begins with a brief introduction about the role of polymers in textile finishing. Then the chapter reviews approaches to introducing different functionalities using speciality polymers and stimuli responsive polymers. The aim is to provide a comprehensive understanding of the scope of these polymers and to facilitate the development of new responsive polymers and hybrids for application in technical textiles.

Textile fabrics made of natural as well as synthetic fibres are modified to get desired hand, texture and other special aesthetic and functional properties through finishing, coating and lamination. This process has been a prime focus in textile manufacturing. Over the last few decades there have been significant developments in the application technologies, machinery and processes for textile finishing, coating and lamination and these are covered in detail in this chapter. All the innovations in this area focus around conservation of chemicals, energy and water and minimization of air and water pollution. Emerging technologies such as plasma treatment of textiles, nanocoating and nanofinishing are also discussed.

The chemistry of synthetic dyes having functions other than color, such as better light-fastness, antimicrobial activity, water repellency, biodegradability, fluorescence and phosphorescence, is described. These dyes belong to the azo, cyanine, coumarin, xanthene, naphthalimide, perylene, thioxanthone, quinonoid, and naphtholactam classes.

Functional finishes that address comfort and protection have become increasingly important in recent years. This chapter will discuss finishes that address thermal and sensorial comfort both from a physical standpoint and from a social perspective. Thermal regulation, moisture management and odor control finishes are among those discussed. Finishes that improve the protective functions of clothing are important to individuals who work or participate in other activities where hazards may be encountered. Flame resistance, liquid barrier, antimicrobial and UV protective finishes are among those discussed. Phase change materials (PCMs) and nanotechnology are some of the newest approaches to providing ‘smart’ finishes impacting comfort and protection. The chapter also addresses the balance that must occur in achieving each type of comfort or protection and considers the health issues that have been identified with various types of these finishes.
