Abstract

Polyethylene terephthalate (PET) fibers are widely used in many fields, but their flammability and molten droplet characteristics during combustion pose a significant safety risk. To address the issue, a novel approach was developed to enhance the flame retardant and anti-dripping performances of PET fabric through a combination of dyeing and mussel-inspired strategy. First, PET fabric was directly dyed with heme chloride (HC) to produce dyed PET fabric (HC-PET), which was then treated by a mussel-inspired tannic acid-based flame retardant (TAPP) and an impregnation-drying-curing process to prepare flame retardant PET fabric (FR-PET). The results indicated that the total heat release (THR) and peak smoke production rate (PSPR) of FR-PET were decreased by 22.8 % and 49.7 %, respectively, and the limiting oxygen index (LOI) was increased from 21 % to 29.8 %, showing good flame retardant properties. Additionally, the UV resistance and antibacterial performances of FR-PET were also significantly improved. In summary, this study provided a feasible approach for the preparation of multifunctional PET textiles with dyeing, flame retardant, anti-dripping, UV resistance and antibacterial performances.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
