By enabling the development of novel materials and methods with distinctive qualities and advantages, biotechnology—the use of live organisms or their products to fulfill specific activities or manufacture products—has the potential to transform the textile industry. Here are a few instances of how biotechnology is used in the manufacture of textiles:
To produce natural fibers: Natural fibers like cellulose and chitin, which can be used to make textiles, can be produced by microorganisms like bacteria and fungi.
Acetobacter xylinum, for instance, can be utilized to create cellulose fibers, which can then be spun into a variety of fabrics.
To improve dyeing processes: Textile dyeing can be made better with the use of biotechnology.
For instance, microorganisms may be employed to create indigo and other natural dyes that can be used to color textiles. Enzymes can also be employed to increase the colors' colorfastness and brilliance, obviating the requirement for harsh chemicals.
Microorganisms to remove dyes from textiles: With the process of biodegradation, microorganisms like bacteria and fungi can also be utilized to remove colours from textiles.
Pseudomonas putida, for instance, can be used to biodegrade azo dyes, which are frequently used in the textile sector.
Enzymes to improve the softness and drape of textiles: Natural fibers like wool and cotton can be softened and given better drape with the help of enzymes, making them more comfortable to wear. Enzymes can also be employed to increase the colors' colorfastness and brilliance, obviating the requirement for harsh chemicals.
Microorganisms in textile desizing: Desizing of textiles is the process of taking the size, or starch, out of woven fabrics during textile manufacture. Enzymes can be utilized in biotechnology to break down the starch molecules into simpler sugars during this process. Enzymatic desizing is a technique that is thought to be a more environmentally friendly substitute for conventional chemical desizing techniques. Enzymatic desizing is a biotechnological method since the enzymes are created by fermentation using microorganisms. The majority of the time, fungi or bacteria are used to produce the enzymes that are used in this procedure because of their propensity to selectively break down starch molecules without harming the fabric's fibers.
Biotechnology in textile scouring: The scouring of textiles, which entails removing impurities like oils, dirt, and waxes from the cloth, is another use for biotechnology. With this procedure, some pollutants can be broken down and eliminated using enzymes. For instance, lipases can be used to dissolve fat or oil-based impurities, whereas proteases can be used to dissolve protein-based impurities, such as blood and sweat stains. In addition to enzymes, microbial scouring agents are another application for biotechnology. In a process known as bioscouring, these agents, which are generated from microbes, can degrade and remove pollutants from the fabric. Since microbial scouring agents are biodegradable and generate fewer effluent byproducts than conventional chemical scouring agents, they are thought to be more environmentally friendly.
To create water-repellent textiles: Through the use of specialized coatings or treatments, biotechnology can be employed to make fabrics that are water-resistant. On textiles, for instance, enzymes can be used to make hydrophobic surfaces, and bacteria can be employed to produce self-assembling peptides that build a coating that repels water.
Creating biodegradable textile finishes: Biotechnology can be utilized to create biodegradable textile finishes, which can help to lessen the environmental impact of textile production and disposal. For instance, microorganisms can be utilized to make biodegradable polymers like polylactic acid (PLA), which is useful for producing a range of finishes.
Developing new types of biodegradable textiles: New kinds of biodegradable textiles can be manufactured using sustainable, renewable resources thanks to biotechnology. For instance, bacteria can be utilized to make biodegradable polymers like polylactic acid (PLA), which is useful in the production of a range of materials.
Improving the sustainability of textile production: Biotechnology can be applied to the textile industry as a whole to increase sustainability in addition to producing new materials and procedures. Bacteria can be employed, for instance, to degrade and reuse textile waste or to create biodegradable fiber substitutes for synthetic ones.
Ethical considerations of using biotechnology in textiles: The use of genetically modified organisms, the usage of them in textiles, and the possibility of misuse or abuse are some ethical issues that the use of biotechnology in textiles may also bring up. The textile sector must take these ethical concerns into account and deal with them responsibly.
Challenges and limitations of using biotechnology in textiles: Although there are numerous potential uses for biotechnology in textiles, there are also certain difficulties and restrictions. Biotechnology-based materials, for instance, may cost more to produce than conventional fibers since they may need specific tools and knowledge. Also, there may be questions about the dependability and scalability of biotechnology-based processes.
Future directions for the use of biotechnology in textiles: Although the application of biotechnology to textiles is still in its infancy, it is probable that the technology will continue to advance over the next few years. The creation of new classes of functional and sustainable materials, the incorporation of sensors and electronics into textiles, and the use of biotechnology to increase the effectiveness and sustainability of the textile manufacturing process are some potential future directions for the use of biotechnology in textiles.
In general, applying biotechnology to the textile industry has the potential to develop novel materials and production techniques with enhanced qualities and sustainability. To ensure that biotechnology is used responsibly and ethically, it is crucial to thoroughly weigh the potential hazards and effects of this technology.
