Recent Advances in the Design of Water Based-Flame Retardant Coatings for Polyester and Polyester-Cotton Blends

Abstract

Over the last ten years a new trend of research activities regarding the flame retardancy of polymeric materials has arisen. Indeed, the continuous search for new flame retardant systems able to replace the traditional approaches has encouraged alternative solutions, mainly centred on nanotechnology. In this context, the deposition of nanostructured coatings on fabrics appears to be the most appealing and performance suitable approach. To this aim, different strategies can be exploited: from the deposition of a single monolayer consisting of inorganic nanoparticles (single-step adsorption) to the building-up of more complex architectures derived from layer by layer assembly (multi-step adsorption). The present paper aims to review the application of such systems in the field of polyester and polyester-cotton blend fabrics. The results collated by the authors are discussed and compared with those published in the literature on the basis of the different deposition methods adopted. A critical analysis of the advantages and disadvantages exhibited by these approaches is also presented.

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

“…In the past several decades, polyester textile has been widely applied to garment, upholstery, and decoration, etc. [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].…”

Durable flame‐retardant and antidroplet finishing of polyester fabrics with flexible polysiloxane and phytic acid through layer‐by‐layer assembly and sol–gel process

“…It should be noted that the treated polyester fabric samples exhibited lower peak HRR (pkHRR) values (80−150 kW/m 2 ) but produced a smaller first peak. This was probably owing to the degradation of the free radicals of the flexible polysiloxane coating . As the soaking time was increased, the first peak became weaker.…”

“…This was probably owing to the degradation of the free radicals of the flexible polysiloxane coating. 27 As the soaking time was increased, the first peak became weaker. This also suggested that PA acted as a free-radicalcapturing agent and captured the free radicals produced by the flexible polysiloxane coating.…”

“…Carosio et al . and Alongi et al . reported that an LbL and sol–gel process improved the melt‐dripping and flame‐retardance behavior of polyester and polyester–cotton blended fabric.…”

“…Therefore, functional deposition is difficult to achieve by the conventional LbL process. Carosio et al 26 and Alongi et al 27 reported that an LbL and sol-gel process improved the meltdripping and flame-retardance behavior of polyester and polyestercotton blended fabric. But inorganic sols crack on the surface of the fabric, 28 and the inorganic sol is mainly deposited between the fabric fibers.…”
