“…The color range is limited and there is a small niche market for colored cottons. The future dream of textile industries will be to sell their products under the eco-friendly banner by using transgenic intensely colored cottons (blues and vivid reds), which is nature's gift to preserve the environment [16,18,19].…”

Biotechnology, a new impetus in the last few years, has seen rapid developments in genetic manipulation techniques (genetic engineering) which introduces the possibility of producing organisms in order to optimize the production of established or novel metabolites of commercial importance and of transferring genetic material (genes) from one organism to another. Industrial biotechnology is the application of technical advances in life sciences to develop commercial products or to incorporate in industrial processes. Enzymes are being used in numerous new applications in the food, feed, agriculture, paper, leather, and textile industries which results in enhanced product quality along with significant reductions in cost and environmental pollution. The potential to harness biotechnology and produce new or modified fibers as well as improving the production yields of existing fibers is being studied. Novel fiber-forming biopolymers with biocompatibility and biodegradability are now being manufactured using large-scale fermentation equipment for medical applications. Natural biological fibers from natural raw materials possessing properties of synthetic fibers have entered the textile field. Enzymatic processes have replaced chemical methodologies in textile manufacturing to obtain a sustainable biobased economy. Biological processes play a major role in the removal of contaminants. The elimination of a wide range of waste materials and polluting substances from the environment is an absolute requirement to promote a sustainable development of our society with low environmental impact. Without such advances in science and technology, the move to a more biobased economy would result in rapid depletion of renewable resources and environmental degradation. The natural protein molecules, enzymes, have paved the way for interdisciplinary partnerships with various textile applications for exploring new avenues in the textile industry. Further research is required for the implementation of commercial enzyme-based processes for the biomodification of synthetic and natural fibers.

The possibility of softening the conditions of biochemical treatment to remove the sizing agent from the surface of the fibers in the preparation of cotton fabric for dyeing has been studied. The efficiency of the α-amylase enzyme was evaluated by the amount of sugars reduced in the modifying solution, as well as by the capillarity of the samples of the treated fabrics. The enzyme used is active towards starch starting from a low concentration (0.02 g/l) and low temperature (32°C). The effect of enzyme concentration from 0.02 to 6.0 g/l, solution pH from 4.5 to 8.5, temperature from 32 to 60°C on the amount of sugars in the solution after enzymatic treatment, and fabric capillarity was determined. Almost complete removal of sizing from the surface of fibers of the original fabric was achieved under moderate and mild processing conditions: α-amylase concentration 1.0÷5.0 g/l, pH=6.0÷7.0, temperature 50-55°C. Based on the dependence of the logarithm of the reaction rate on the reciprocal temperature, the activation energy of the desizing reaction was calculated, which turned out to be equal to E = 17.5 kJ/mol. The low activation energy shows that the desizing process is carried out under energetically favorable conditions with moderate heating. The surface morphology of treated and untreated samples of cotton fabric was studied by scanning electron microscopy. The removal of the adhesive substance from the surface of the fibers, the separation of individual fibers, and the smoothing of the fabric surface after treatment with an amylase solution were recorded.
