“…During the fabrication, the alginate spinning dope in the syringe is extruded into the CaCl 2 solution to finish the ion exchange and then the primary fibers will be obtained without further stretching. In addition, to enhance the mechanical performance and extend the application properties of alginate fiber, some other functional polymers or cross-linkers were added to the spinning dose to produce the hybrid fiber [ 40 , 42 , 43 ]. For instance, the catechol [ 44 ], quaternary ammonium chitosan (QAC) polysaccharide polyelectrolyte complex (PEC) [ 45 ] and the hydrolysis compound of vinyl triethoxy silane (VTES) [ 46 ] was incorporated in the alginate solution, respectively, to fabricate the composite fiber by the homemade wet spinning device.…”

“…Some other researchers focused on the incorporation of reinforced materials in the spinning solution, which helped to strengthen the cross-linking interaction between the fiber molecular chain. The popular doping additive materials include the hydrophilic polymers such as collagen [ 45 , 57 ], chitosan [ 58 , 59 ], cellulose nanocrystal [ 40 , 60 ] and its derivative [ 55 ] or the nanoparticles including silica [ 61 , 62 ], hydroxyapatite [ 63 , 64 ] and graphene [ 42 , 65 ]. These strategies introduce extra hydrogen bond, ionic bond or covalent bond in the alginate fiber.…”

As a natural linear polysaccharide, alginate can be gelled into calcium alginate fiber and exploited for functional material applications. Owing to its high hygroscopicity, biocompatibility, nontoxicity and non-flammability, calcium alginate fiber has found a variety of potential applications. This article gives a comprehensive overview of research on calcium alginate fiber, starting from the fabrication technique of wet spinning and microfluidic spinning, followed by a detailed description of the moisture absorption ability, biocompatibility and intrinsic fire-resistant performance of calcium alginate fiber, and briefly introduces its corresponding applications in biomaterials, fire-retardant and other advanced materials that have been extensively studied over the past decade. This review assists in better design and preparation of the alginate bio-based fiber and puts forward new perspectives for further study on alginate fiber, which can benefit the future development of the booming eco-friendly marine biomass polysaccharide fiber.

“…7 Regression model for degradation in water of HPMC films reinforced with different MFC/NFC contents When HPMC comes into contact with water, the hydration process quickly occurs, leading to a transition from vitreous to elastic state, which results in formation of a gel with the water (Kiss et al 2019). HPMC has a large amount of hydroxyl groups on its surface, which absorb large amounts of molecules and disperse the matrix (Ci et al 2020).…”

Damages to ecosystems, due to the consumption of petroleum-based materials, can be mitigated with the use of biopolymers such as cellulose derivatives. The objective was to evaluate the influence of different proportions of cellulose micro/nanofibrils (MFC/NFC) on the properties of hydroxypropyl methyl cellulose (HPMC) films. Films were prepared using proportions of 0, 25, 50, 75 and 100% (w/w) of MFC/NFC of Pinus sp. in relation to HPMC. The physical, barrier, surface, optical, morphological and mechanical properties were evaluated. Data were analyzed with descriptive statistics, linear regression, principal component analysis and Pearson correlation. Solids content, basis weight and density values increased with higher MFC/NFC amount, while thickness and porosity were reduced. SEM images showed that films with more than 50% MFC/NFC had a more granular surface resulting in reduction of transparency from 80 to 65%. The water vapor penetration did not differ between films and the degradation in water was reduced from 40 to 5% as MFC/NFC was added. There were no differences for contact angle and wettability, but all films showed high resistance to fat penetration. Films with MFC/NFC contents between 75 and 100% showed higher values for tensile strength (50 to 65 MPa) and Young's modulus (6 to 10 MPa) and lower elongation at break (1 to 2%). The experimental results indicated that films with MFC/NFC contents above 50% have potential to be used as packaging material.

“…Current research on the mechanical properties of alginate fiber focuses on the incorporation of a doping reagent in the spinning solution, which works as reinforcing fillers or increases the molecule cross-linking strength. Popular additives include hydrophilic polymers, such as chitosan, , collagen, , cellulose nanocrystal, , and its derivative, or nanoparticles, including hydroxyapatite, , silica, , and graphene. , These studies provided efficient and facile strategies to reinforce calcium alginate fiber, but the incorporation of additives increases viscosity of spinning dopes that form the blocking clot as well as nanofiller agglomeration, which, in return, causes an inconsistent structure, while a lower concentration of additives will not benefit improving the fiber mechanical performance. Moreover, the doped polymers in calcium alginate fiber, if itself inflammable, will deteriorate the overall fiber flame-retardant performance …”

Petroleum-based synthetic flame-proof fiber releases toxic volatile organic compounds in thermal decomposition process and has other problems, like tickling feeling and high density. A natural polysaccharide, calcium alginate, is an intrinsic fire-resistant biodegradable material, but its limited mechanical performance prevents it from being a practical flame-retardant fabric. To address this problem, Na2CO3 was doped into alginate spinning solution to obtain in situ generating CaCO3 nanoparticle-reinforced alginate fiber by microfluidic spinning technique. Comparative analysis illustrated that incorporation of 0.50% Na2CO3 into the fiber greatly improved its mechanical performance; meanwhile, in situ generated CaCO3 nanoparticles also throttled oxygen and heat flow in burning, endowing the fiber with excellent flame retardancy. The prepared composite fiber released less heat, smoke, and toxic volatile organic compounds in burning, which reduced the fire hazard. The formed residue char and pyrolysis products functioned as the physical barrier and displayed a synergistic effect to inhibit oxygen and heat transmission and impede the further combustion. All of the results demonstrate that the obtained fiber exhibits a good mechanical and flame-retardant performance, making it an ideal candidate as a fire-protection textile.
