Green Advances in Wet Finishing Methods and Nanoparticles for Daily Textiles

Macromolecular Rapid Communications, Год журнала: 2024, Номер unknown

Опубликована: Окт. 27, 2024

Abstract This work presented an overview of greener technologies for realizing everyday fabrics with enhanced antibacterial activity, flame retardancy, water repellency, and UV protection. Traditional methods improving these qualities in textiles involved dangerous chemicals, energy water‐intensive procedures, harmful emissions. New strategies are response to the current emphasis on process product sustainability. Nanoparticles (NPs) suggested as a potential alternative hazardous components textile finishing. NPs found efficiently decrease virus transmission, limit combustion events, protect against radiation, prevent from entering, through variety mechanisms. Some attempts made increase efficiency promote long‐term adherence surfaces. wet finishing implemented combination advanced green (plasma pre‐treatment, ultrasound irradiations, sol‐gel, layer‐by‐layer self‐assembly methods). The fibrous surface is activated by adding functional groups that facilitate grafting substrate basic interactions (chemical, physical, or electrostatic), also indirectly via crosslinkers, ligands, coupling agents. Finally, other options explore use synthesized bio‐based materials hybrid combinations, well inorganic synthesis realize ecofriendly able provide durable protective fabrics.

Fabrication of Flame Retardant PA6/Three-Dimensional Braided Glass Fiber Composites via in-situ Polymerization

Functional Materials Letters, Год журнала: 2024, Номер 17(06)

Опубликована: Май 20, 2024

Reaction injection molding method is employed to improve flame retardancy and mechanical properties of three-dimensional braided glass fiber (3D-braided-GF) reinforced in situ polymerized polyamide 6 (PA6) composites. The kernel lies adding retardants, hexaphenoxycyclotriphosphazene (HPCTP), the reactive monomers allow it be filled into composites during preparing PA6 through anionic polymerization, which enables retardants achieve better dispersion. In addition, extremely low-viscosity are easier immerse 3D-braided-GF, ameliorating interfacial adhesion between GF PA6. preliminary research indicates that samples with 10 wt.% HPCTP concentration can best a satisfied flame-retardant grade (UL 94 HB). However, incorporation 15 samples, optimum V2) reduced performance obtained. Furthermore, dual mechanism both gaseous condensed phases further elucidated. This study provide reference for scenarios high requirements properties, such as high-speed rail aircraft.
