“…Hand hydrophobic cotton fabrics are gaining interest because of additional characteristics like antifouling, friction reduction, self-cleaning and water repellence [312] hence, various surface modifications are already in use for making cotton fabric hydrophobic. In this regard Zhao [312] adopted an environmentally-friendly and cheap method, by coating cotton fabric with poly (ethylene glutarate) and the coated fabric showed improved hydrophobicity and wrinkle resistance. The wrinkle resistance was improved due to in situ enzymatic formation of monomers and oligomers of poly (ethylene glutarate) at the surface of cotton fabric.…”

Cotton is the most significant natural fibre and has been a preferred choice of the textile industry and consumers since the industrial revolution began. The share of man-made fibres, both regenerated and synthetic fibres, has grown considerably in recent times but cotton production has also been on the rise and accounts for about half of the fibres used for apparel and textile goods. To cotton's advantage, the premium attached to the presence of cotton fibre and the general positive consumer perception is well established, however, compared to commodity manmade fibres and high performance fibres, cotton has limitations in terms of its mechanical properties but can help to overcome moisture management issues that arise with performance apparel during active wear. This issue of Textile Progress aims to: i. Report on advances in cotton cultivation and processing as well as improvements to conventional cotton cultivation and ginning. The processing of cotton in the textile industry from fibre to finished fabric, cotton and its blends, and their applications in technical textiles are also covered. ii. Explore the economic impact of cotton in different parts of the world including an overview of global cotton trade. iii. Examine the environmental perception of cotton fibre and efforts in organic and genetically-modified (GM) cotton production. The topic of naturally-coloured cotton, post-consumer waste is covered and the environmental impacts of cotton cultivation and processing are discussed. Hazardous effects of cultivation, such as the extensive use of pesticides, insecticides and irrigation with fresh water, and consequences of the use of GM cotton and cotton fibres in general on the climate are summarised and the effects of cotton processing on workers are addressed. The potential hazards during cotton cultivation, processing and use are also included. iv. Examine how the properties of cotton textiles can be enhanced, for example, by improving wrinkle recovery and reducing the flammability of cotton fibre.

“…Most of the known aliphatic polyesters can be regarded as biobased polymers [6,7] as the majority of the starting reactants can be obtained from biomass feedstock. Aliphatic polyesters have superior biodegradability, biocompatibility and probable bioresorbability, and can be applied to diverse potential fields like textiles manufacturing [5,8], food packaging as well as biomedical and pharmaceutical fields [5,[9][10][11][12]. The enzymatic polymerization of aliphatic polyesters has been considered therefore as a promising alternative to the traditional chemical polymerization.…”

“…These properties allow them to be employed in a variety of biochemical reactions, including acidolysis, aminolysis, alcoholysis when in an aqueous solution, esterification, transesterification and acylation when in non-aqueous media [13,14]. Based on these specific properties, lipases are widely applied as bio-catalysts in the textile field [8], food manufacture [15], biomedical and pharmaceutical industry [16], and energy (biodiesel) production [17,18]. Lipases can also be described as bio-catalysts for various organic solvents [19] and emulsions [20].…”

“…Hydrophobic cellulosic materials are highly demanded considering their specific water-repellent properties. It imparts to the materials a series of excellent functional performances such as hydrophobicity, selfcleaning, antifouling, and friction reduction [8,23,24]. Cotton cellulose holds remarkable advantages when used as substrate for the production of hydrophobic materials.…”

Several polyesters were synthesized from ethylene glycol, glycerol and adipate, succinate dimethyl esters. Immobilized Candida antarctica lipase B was used as catalyst for 6 h under vacuum at 70°C without any further solvents. The highest conversion rate of 88.5% occurred for the polymerization of poly(ethylene adipate), evaluated by 1 H NMR. MALDI-TOF analysis indicated that most of the oligomers formed were dimers or trimers. After successfully synthesize the polyesters we setup the optimal conditions for their in-situ coating onto cotton substrates with a soluble lipase from Thermomyces lanuginosus. This work presents a novel bio-approach to impart hydrophobic properties to coated cotton-based fibre materials.

“…However, these technologies are constricted by their sustainability and environmental concerns and cost. An ecologically greener alternative to current practice is presented by Zhao and collaborators [4], who carried out a lipasecatalyzed solvent-free synthesis of poly (ethylene glutarate) monomers and oligomers to coat the surface of cotton fabrics for the first time.…”

Biotechnology has been applied as a valuable tool to produce useful bio-based products from non-petrochemical renewable resources. Biologically produced polymers present advantages related with the biodegradability, performance, cheapness of substrate and defined structural variability. Beyond that, enzymes, the most proficient catalysts, continue to offer the most competitive processes compared with the chemical ones. Advances in protein engineering technology and the environmental and economic requirements contribute for the continuous search of acceptable biotechnological solutions for the areas, including, polymer and textile, medical, pharmaceutical, among others. New trends and strategies have been highlighted in recent studies leading to significant advances in enzyme biocatalysis.
