Preface
The book mainly deals with the basic fundamentals of enzyme technology
and their applications in textile processing of both natural and synthetic fibres
for enhancing their functional characteristics. With increasing awareness
about the environmental concern and usage of eco-friendly agents, today
the researchers and scientists are finding ways to treat the textile materials
without use of chemicals. To fulfill the space many researchers are developing
the enzyme-based products for industrial applications to enhance the product
functional properties and uses.
The book is broadly divided into eight chapters namely enzyme technology,
industrial enzymes, bioprocessing of natural fibres, synthetic fibres, enzymes
in textile effluents, safety and precaution in handling enzymes, bioprocessing
of organic cotton and enzyme processing for hygienic and health care textiles.
Processing of cotton fabrics in single bath and continuous operations of
desizing, scouring and bleaching processes and their effluent loads have been
discussed both enzyme- and chemical-based wet processing. This book also
describes the future scope of enzyme technology for hygienic and healthcare
textile product development and safety aspects of handling enzymes in the
textile industries.
This book would be very useful to undergraduate and postgraduate
students of textile technology, fashion technology, textiles chemistry and textile
processing; researchers working in academic and industrial R&D, and colleges
and universities offering textile technology and biotechnology programs. In
short, this book presents a refreshingly original approach in emphasizing the
interface between enzyme technology and textile materials apart from dealing
with diverse methods and techniques used in industrial practices.
We hope that it would provide guidelines to researchers, scientists and
industrialists as well as students a useful source of information in the important
field of textile processing through enzyme technology.
