“…The mechanical properties of the obtained fibers are shown in Table 1 , along with other synthetic, natural and regenerated (man-made) cellulosic and organic synthetic fibers. The mechanical properties of Lyocell produced with BNC are similar with data for Viscose and Lyocell fibers ( Makarov et al, 2019 , 2020 ).…”

“…Due to the difference in the DP between BNC and plant cellulose, the use of the same concentration may yield different results, given the large difference in viscosity. For example, a 6% (m/m) solution of BNC (DP 2000) has a viscosity 10 3 Pa.s, which in the case of wood cellulose (DP of 600) is achieved only at 18% (m/m) ( Makarov et al, 2019 ).…”

“…Then, under temperature (105°C) and shear rate, the cellulose dissolves into a highly homogeneous and concentrated solution ( Golova et al, 2013 ). This method has been successfully used with BNC fibers with a DP of ∼1500 and a solid-phase activation of BNC and NMMO (water < 10%); the mixture was heated at 120°C until a fluid solution was obtained ( Makarov et al, 2019 ). The authors claim that the (mechanochemical) activation is mandatory for a homogeneous solutions to be obtained, as no swelling occurs.…”

There is an emerging environmental awareness and social concern regarding the environmental impact of the textile industry, highlighting the growing need for developing green and sustainable approaches throughout this industry’s supply chain. Upstream, due to population growth and the rise in consumption of textile fibers, new sustainable raw materials and processes must be found. Cellulose presents unique structural features, being the most important and available renewable resource for textiles. The physical and chemical modification reactions yielding fibers are of high commercial importance today. Recently developed technologies allow the production of filaments with the strongest tensile performance without dissolution or any other harmful and complex chemical processes. Fibers without solvents are thus on the verge of commercialization. In this review, the technologies for the production of cellulose-based textiles, their surface modification and the recent trends on sustainable cellulose sources, such as bacterial nanocellulose, are discussed. The life cycle assessment of several cellulose fiber production methods is also discussed.

“…As a result, a content of alpha-cellulose in BC reaches 97% [6,7]. The other features of BC are high polymerization degree, which exceeds significantly the corresponding values for wood cellulose, and high content of crystalline phase [8][9][10].…”

“…The reason is the system of inter-and intramolecular hydrogen bonds, which are responsible for the package density and structure of the polymer [16]. Among the described direct solvents for BC can be found ionic liquids [17,18], LiCl/DMAc [19], N-methylmorpholine-N-oxide (NMMO) [10,20,21], aqueous solutions of zinc chloride [22], etc.…”

In the present study, one of the possible methods of the bacterial cellulose processing is proposed via its dissolution in N-methylmorpholine-N-oxide using the stage of mechano-chemical activation of the solid polymer–solvent system. Preliminary solid-phase activation is apparently a decisive factor affecting the dissolution rate of bacterial cellulose in N-methylmorpholine-N-oxide. The effects of bacterial cellulose concentration, solvent nature, degree of polymerization and temperature on dissolution time were studied. The rheological behavior of the solutions does not change at 120 °C for at least half an hour that allowed us to process such solutions for films preparation. The films from these solutions by means of dry-wet jet spinning in aqueous coagulant were formed. The structure of the nascent cellulose and formed films was tested by the X-ray diffraction method and SEM. The thermal behavior of the films revealed an increase in the carbon yield for the formed films compared to the nascent bacterial cellulose. The process of film pyrolysis is accompanied by exothermic effects, which are not typical for wood cellulose. Some reasons of such thermal behavior are considered.

Whilst synthetic polymers have changed the world in many important ways, the negative impacts associated with these materials are becoming apparent in waste accumulation and microplastic pollution due to lack of biodegradability. Society has become aware of the need to replace or substitute environmentally persistent synthetic polymers, and cellulose has received a large amount of attention in this respect. The mechanical properties of cellulose, its renewable nature and biodegradability are advantageous properties. Drawbacks exist for the use of plant cellulose (PC), including the water footprint of cotton, deforestation associated with wood/dissolving pulp, and the extensive processing required to refine plants and wood into pure cellulose. Bacterial cellulose (BC), also known as microbial cellulose, is gaining momentum in both academic and industry settings as a potential solution to the many drawbacks of plant-based cellulose. Compared to PC, BC has high purity, crystallinity and degree of polymerisation, and can be manufactured from waste in a way that yields more cellulose per hectare, per annum, and requires less intense chemical processing. Native bacterial cellulose can be formed and shaped to an extent and is found in a variety of commercial products. However, dissolving and regenerating bacterial cellulose is a potential avenue to broaden the applications available to this material. The aim of this study is to review the applications which utilize regenerated bacterial cellulose, with a focus on the dissolution/regeneration methods used and discussing the associated limitations and future outlook.
