Über dieses Buch

This book highlights the sustainability aspects of textiles and clothing sector in light of nanomaterials and technologies. The invasion of nano in every industrial sector has been important and has made remarkable changes as well as posed new challenges, including the textiles and clothing sector. There is quite a great deal of research happening in terms of nano materials for textiles across the globe, some of which are covered in this book.



Advances in Nanotextile Finishes—An Approach Towards Sustainability

The chapter critically surveys the recent development trends in nanotextile finishes. Garments for special needs comprising of the functional aspects such as protective, medical treatment and care, have been considered through treatment with silver nanoparticles and have been related to sustainability. The micro- and nanoencapsulation of 100 % cotton denim fabric using three herbal extracts have been studied for antimicrobial efficiency, resulting in improvement in durability and good resistance to microbes over 30 industrial washes. The synthesis, characterization, and application of nanochitosan on cotton fabric has been studied, and the treated fabrics were evaluated for appearance, tensile, absorbency, stiffness, dyeing behaviour, wrinkle recovery, and antibacterial properties. Polyester fabric has been treated with nanosized dispersed dye particles without carrier, using ultrasound. This has been used for optimizing the parameters for the preparation of the printing paste. Attempt has been made to improve the handle property of jute polyester-blended yarn to produce union fabric with cotton yarn, intended for winter garment. The findings indicate that nano–micropolysiloxane-based finishing exhibit better improvement in the surface morphology, handling, and recovery property of the fabric as compared with other finishing combinations. Viscose fabrics have been modified to improve the attraction for metal oxides such as aluminium, zinc, or titanium in order to impart antimicrobial activity against two types of microorganisms. Nanosafe textile using the extracts of yellow papaya peel has been developed by extracellular synthesis of highly stable silver nanoparticles. Cotton fabrics with smart properties have been developed by functional finishing with stimuli-responsive nanogel using a combination of biopolymer and synthetic polymer in the synthesis of nanogel. The findings reveal that the application of nanogel as a smart finishing system affects the intrinsic cotton properties and also improves the common textile quality by providing new features of stimuli responsiveness. Above all these, the newer concepts of the nanotextile finishes discussed in the chapter promise enhancement in the existing properties of textile materials, increase durability, promote ecofriendliness and economy, and thus pave the way towards achieving better sustainability.

Nanochemicals and Effluent Treatment in Textile Industries

The textile industry deals with the design and production of various fabrics with a web of processes intertwined to produce the final product. Among these, the dyeing and finishing processes in particular use large quantities of water and consequently lead to production of large volumes of wastewater. Colour, dissolved solids, toxic heavy metals, residual chlorine and other non-degradable organic materials are the pollutants of major concern present in effluent from textile industries. Advancements in nanotechnology have enabled us to explore the applications of nanochemicals for effluent treatment in textile industries. Nanochemicals have the desired properties required for pollutant and pathogen removal from wastewater by methods such as chemical oxidation, disinfection and photocatalysis. This chapter discusses the various pollutants present in wastewater effluent from textile industries and their sources, the present effluent standards and the application of nanochemicals for wastewater treatment.

Insights into the Functional Finishing of Textile Materials Using Nanotechnology

Over the past few decades, there is an emergence of new multidisciplinary approaches to functionalize different textile materials. Nanotechnology is increasingly attracting scientific attention to develop multifunctional textiles for various end uses among all technologies. Nanoparticles play vital role in coloration and, in view of their large surface area-to-volume ratio and high surface energy, have imparted novel properties such as microbial resistance, flame retardancy, and self-cleaning property to different textile surfaces. This book chapter emphasizes on recent functional treatments of both natural and synthetic textile materials using nanotechnology. Applications of the sustainable nanotextiles in many of the sectors such as medicine and protective clothing are also critically discussed.
