A Green Water-Soluble Cyclophosphazene as a Flame Retardant Finish for Textiles

Abstract

Poly- and cyclophosphazenes are excellent flame retardants but currently, are not used as textile finishing agents because water-soluble and permanent washing systems are missing. Here, we demonstrate for the first time, the successful usage of a water-soluble cyclotriphosphazene derivative for textile finishing for cotton, different cotton/polyester, and cotton/polyamide blend fabrics. A durable finish was achieved using a photoinduced grafting reaction. The flame retardant properties of the various fabrics were improved with a higher limiting oxygen index, a reduced heat release rate, and an exhibition of intumescent. Furthermore, the finished textiles passed several standardized flammability tests.

Synthesis and Characterization of Aluminum 2-Carboxyethyl-Phenyl-Phosphinate and Its Flame-Retardant Application in Polyester

“…[1,2], because of its excellent properties, such as low cost, being resistant to chemicals, dimensional stability, and good physical features [3][4][5][6][7][8]. However, polyester textile is flammable and it will melt dripping during combustion, which caused potential fire risks to people's lives and property [9,10]. Therefore, it is necessary to impose flame retardancy to textile in work clothes and tents applications [11,12].…”

Environmentally Friendly Inorganic Materials for Anti-flammable Cotton Fabrics

“…The treatment of ammonia by thermal heat treatments includes phosphorus-oriented compounds, pre-condensates and fibre responsive compounds which require multiple steps in the process. [46,47] Some of the more important requirement for ideal durable retardant is the following   Capability to impart resistance to fire, that is to say, resistance to flame and glow   Application for all weight textiles and preferably water solutions   Easy to apply on existing finishing equipment, preferably without danger. The surface of fibres may be fitted with a durable flame retardant and/or penetrate the fibres.…”

In‐situ synthesis and adhesion method to prepare phosphorous–nitrogen compounds flame‐retardant wood pulp paper with high efficiency and durability

“…And we also explored the acid–base synergistic flame‐retardant WPP, and the LOI value reached 35.7% with guanidine phosphate/borax FR system 18 . Nevertheless, a majority of reported phosphorous containing FRs are not long‐lasting due to water solubility and hygroscopicity, thus incurring the deterioration of flame‐retardant property in humid environment 19‐22 . Reactive‐type FRs adopted in cellulosic materials are universally graft‐reacted with the hydroxyl groups of cellulose 23,24 .…”
