Bio-based textile processing through the application of enzymes for environmental sustainability
International Journal of Technology Management & Sustainable Development, 2020
Textile industries contribute significantly to the economy of many developing countries. Every year, these countries export millions of dollars’ worth of textile products to developed countries. However, textile industries use expensive and corrosive chemicals that pose a significant threat to environmental quality and public health. This has led to serious concerns and necessitated the inclusion of safer and environmentally friendly alternatives. Consequently, bio-based processing has created a new approach utilizing biotechnological advances. This article uses evidence from the scientific literature to examine the application of industrial biotechnology in textile-processing industries, which includes enzymes, as a sustainable alternative to the harsh toxic chemicals currently used in textile processing. The article draws on evidence that enzymes offer a competitive advantage over chemicals with less resource requirements (energy and water), reduced emission and less waste. Due to...
APPLICATION OF ENZYMES IN TEXTILE INDUSTRY
The word Biotechnology is a cross between the Greek words 'bios' (everything to do with life) and 'techniques' (involving human knowledge and skills). Biotechnology can simply be defined as the application of living organism and their components to industrial products and processes. Biotechnology offers the potential for new industrial processes that require less energy and are based on renewable raw materials. Biotechnology makes use of biological systems to manufacture products and provide services. The biological systems that have traditionally been used are organisms such as yeasts, fungi or bacteria. Thus, bio-tech can simply be defined as the application of scientific and engineering principles to the processing of materials by biological agents to provide industrial products and processes, and an important technology that will have a large impact on many different industrial sectors in the future. It finds extensive application in textiles and allied fields. The application of biotechnology to textile processing mainly consists of application of enzymes to textile materials.
Dyeing of textiles and textile materials has been going parallel to the human life since time immemorial. Natural protein fibers especially wool, silk, and cotton are widely used for dyeing purposes in the modern textile industrial sectors due to their comfort when wearing. In this chapter, fiber protein structure-function relationships are briefly discussed with enzymatic processing routes of textile materials with respect to the increasing dyeing efficiency and other novel functional applications. Fiber/fabric (wool, silk, cotton) biomodifications are described in detail with respect to various classes of enzymes such as cellulases, lipases, xylanases, oxygenases, proteases, transglutaminase, tyrosinase, and laccase. With the processing and development of new dyeing and finishing strategies, enzymatic treatments have become important environmental friendly technologies which not only fulfill the demand of the traditional textile industry but also improve quality of our life, meet the requirement of textile industrial sectors in terms of minimizing pollution levels, environmental protection levels, comfort, and health.
Sustainable Textile Processing by Enzyme Applications
Biodegradation Technology of Organic and Inorganic Pollutants
Enzymatic treatments have gained popularity in the textile industry because of environmental friendly and energy conserving alternatives. Advancement in biotechnology and modification of enzymes has been focused based on various textile process applications. All the manufacturing steps of textile chemical processing, enzymes are using for implementations of the green technology to meet up the challenge of fourth industrial revolution. In this category, amylases, peroxidase used for desizing and bleaching, cellulase activates for bio polishing and denim finishing. This chapter summarizes the current developments of enzyme technology and highlights the environment-friendly and sustainable enzymatic textile processing in the textile industry.
Enzymes: A revaluation in textile processing
The use of enzymes in the textile chemical processing is rapidly gaining globally recognition because of their non-toxic and eco-friendly characteristics with the increasingly important requirement for textile manufacturers to reduce pollution in textile production. Enzymes sources, activity, specificity, reaction, mechanism and thermodynamics, function of textile processing with enzymes, major enzymatic applications in textile wet processing and promising areas of enzyme applications in textile processing are discussed. The aim is to provide the textile technologist with an understanding of enzymes and their use with textile materials.
Trends in bio-processing of textiles: A review
Savremene tehnologije, 2014
worldwide, the investigations are carried out to substitute conventional chemical textile processes by environmentally friendly and economically attractive bioprocesses using enzymes. The application of cellulases for denim finishing and laccases for decolourization of textile effluents, and textile bleaching are most recent commercial advances. New developments rely on the modification of natural and synthetic fibres. This work represents a review of enzyme applications in textile processes. The described bio-processings were accompanied by a significantly lower consumption of energy, water, chemicals, time and costs. So it has advantages as well as in terms of ecology as in economy.
Enzyme Applications in Textile Preparatory Process: A Review
2012
Industrial use of biotechnology is bringing about new products and processes aimed at the use of renewable resources, as well as the application og green technologies with low energy consumption and environmentally healthy practices. Textile processing is a growing industry that traditionally has used a lot of water, energy and harsh chemicals.
Application of enzymes for textile fibres processing
This review highlights the use of enzymes in the textile industry, covering both current commercial processes and research in this field. Amylases have been used for desizing since the middle of the last century. Enzymes used in detergent formulations have also been successfully used over the past 40 years. The application of cellulases for denim finishing and laccases for decolourization of textile effluents and textile bleaching are the most recent commercial advances. New developments rely on the modification of natural and synthetic fibres. Advances in enzymology, molecular biology and screening techniques provide possibilities for the development of new enzyme-based processes for a more environmentally friendly approach in the textile industry.
Comparison between conventional chemical processes and bioprocesses in cotton fabrics
2015
Textile processing is a growing industry that traditionally has used a lot of water, energy and harsh chemicals. They are also not easily biodegradable. Biotechnology in textiles is one of the revolutionary ways to promote the textile field. Bio-processing were accompanied by a significant lower demand of energy, water, chemicals, time and costs. Due to the ever growing costs for water and energy worldwide investigations are carried out to substitute conventional chemical textile processes by environment-friendly and economically attractive bioprocesses using enzymes. Enzymes are known for their specificity, high efficiency and ability to work under milder conditions and thus inexorably provide a promising solution to those problems. So it has advantages as well in terms of ecology as in economy. This research paper focuses on a comparison analysis between the conventional pre-treatment processes with bio-preparation of textile-based enzymes.
