“…The early degradation of BC-PA and BC-PA-XY may be attributed to the catalytic dehydration and crosslinking of phosphoric acid during the pyrolysis of the phosphoric compound. 68 During the second stage (170-260 C), BC-PA and BC-PA-XY lost most of their mass, approximately 32.535% and 34.829%, respectively. This was attributed to the cellulose degradation, resulting in the formation of char residues and the release of water and gases including carbon monoxide (CO) and carbon dioxide (CO 2 ).…”

This study aims to develop bacterial cellulose with enhanced flame retardancy and flexibility. The bacterial cellulose was phosphorylated with phytic acid to improve its flame retardancy. Urea and xylitol were used as plasticizers, and their effects in improving the flexibility of bacterial cellulose were compared and evaluated. The optimal conditions for producing phosphorylated bacterial cellulose were found to be as follows: phytic acid:xylitol molar ratio of 1:10, phytic acid concentration of 10% (o.w.f.), and shaking at 30°C for 30 min at 90 rpm in a shaking water bath. A thermogravimetric analysis revealed that phosphorylated bacterial cellulose exhibited enhanced thermal properties compared with the original bacterial cellulose. Fourier transform infrared spectroscopy and X-ray diffraction confirmed that the chemical and crystalline structures of bacterial cellulose remained unchanged after phosphorylation. Mechanical properties such as the tensile strength, flexibility, and dimensional stability of the as-produced phosphorylated bacterial cellulose improved by using xylitol. In particular, the tensile strength and flexibility of the phosphorylated bacterial cellulose increased 5.7 and 2-fold, respectively, compared with those of the original bacterial cellulose. Therefore, this study demonstrated that the flame retardancy and flexibility of bacterial cellulose can be improved by using eco-friendly materials such as phytic acid and xylitol. The as-produced phosphorylated bacterial cellulose can be proposed as a fabric material with sufficient mechanical properties.

It is well known that bacterial infections and fire-hazards are potentially injurious in daily life. With the increased security awareness of life and properties as well as the improvement of living standards, there has been an increasing demand for multifunctional textiles with flame retardant and antibacterial properties, especially in the fields of home furnishing and medical protection. So far, various treatment methods, including the spray method, the dip-coating method, and the pad-dry-cure method, have been used to apply functional finishing agents onto fabrics to achieve the functionalization in the past exploration stage. Moreover, in addition to the traditional finishing technology, a number of novel technologies have emerged, such as layer-by-layer (LBL) deposition, the sol-gel process, and chemical grafting modification. In addition, some natural biomasses, including chitin, chitosan (CS), and several synthetic functional compounds that possess both flame-retardant and bacteriostatic properties, have also received extensive attention. Hence, this review focuses on introducing some commonly used finishing technologies and flame retardant/antibacterial agents. At the same time, the advantages and disadvantages of different methods and materials were summarized, which will contribute to future research and promote the development and progress of the industry.

Flame retardant and antibacterial sodium alginate (SA) fiber were fabricated using the bio-based flame retardant of phytic acid and DL-arginine successively, and then the morphological structures, combustion behavior, thermal stability, and mechanical as well as antibacterial properties of SA fiber were investigated carefully. It is found that when the additional amount of PADL (reaction products of phytic acid and DL-arginine) in SA composite fiber is 20 wt%, its limiting oxygen index (LOI) is 40.0 ± 0.3%, and UL−94 is V−0 grade. The combustion behavior of composite fiber shows that PADL can effectively reduce combustion heat and promote carbon formation. Its peak of HRR (pkHRR) is 5.9% of pure SA fiber, and the residual carbon increases from 23.0 ± 0.1% to 44.2 ± 0.2%. At the same time, the density of the residual carbon increases gradually. PADL can promote SA to form expanded carbon with increasing density, and isolate the heat and volatilization of combustible gases. The guanidine group of DL-arginine can interact with the cell membrane to kill bacteria, and the antibacterial property of SA composite fiber is increased by 30%. This study provides a very ecological, safe, environmentally friendly and simple method to prepare flame retardant and antibacterial SA composite fiber with bio-based materials.
