AB  - Poor antimicrobial activity and lack of protection against UV irradiation are weaknesses of cottontextiles. In an attempt to impart superior antimicrobial and UV-protective properties to cotton, layer-by-layer deposition of chitosan and magnesium lignosulfonate, and in situ synthesis of silver (Ag)nanoparticles (NPs), was performed. Lignin, in a chitosan/lignin multilayer, simultaneously acts as a UVprotective macromolecule and natural reducing and stabilizing agent, allowing formation of Ag NPs. Fourbilayers of this coating is sufficient for fabrication of a chitosan/lignin/Ag-NP textile nanocompositetreatment with 50+ UV protection. 100% reduction of Gram-negative bacteria Escherichia coli, gram-positive bacteria Staphylococcus aureus, and yeast Candida albicans can be achieved with a 12-bilayercoating, when 20 mM silver nitrate solution and sodium borohydride are applied. On the other hand,four bilayers impregnated with Ag NPs, using 10 mM silver nitrate solution, provides sufficientantimicrobial activity independent of an added reducing agent. This treatment exhibits no inhibition ofhuman keratinocyte cells growth on the skin, indicating low cytotoxicity.

AB  - The flammability of polyester textiles remains a significant challenge that must be overcome to allow their use in a variety of clothing and upholstery applications. In this work, water-based polyelectrolyte solutions composed of chitosan (CH) and pectin (P), as carbon-rich biomacromolecules, and mono ammonium phosphate (MAP) were deposited on enzyme/corona modified polyester via layer-by-layer (LbL) deposition. Four bilayers (BL) of 1% CH3/(1% P-30% MAP)4.2 renders the polyester fabric self-extinguishing in vertical flame testing. This recipe yields a 42.6% lower peak heat release rate and a nearly 40% reduction in the fire growth capacity, compared to uncoated polyester, as measured by micro cone calorimetry. The enzyme/corona modification, combined with the CH/(P-MAP) intumescent system, results in a very effective flame retardant treatment with few BL deposited.

AB  - Creating multifunctional textiles using chemicals from renewable sources is challenging. In an effort to develop a sustainable and efficient multifunctional cotton treatment, a lignin-based multilayer nanocoating comprising magnesium lignosulfonate, chitosan, and monoammonium phosphate (MAP) was deposited using layer-by-layer assembly. A five bilayer coating adds 15.5 wt % to cotton and imparts fire extinguishing behavior and excellent UV and antimicrobial protection to the fabric. Just a two bilayer coating imparts sufficient self-extinguishing behavior to pass the standard vertical flame test. The combined influence of lignin as a char-forming and UV-protective macromolecule, chitosan as a char-forming biopolymer, and MAP acting as an antimicrobial agent (and a blowing agent and an acid source in an intumescent flame retardant system) results in a very powerful multifunctional textile treatment with very few layers of deposition.
