Abstract

Eco-friendly flame-retardant fabrics have recently been widely concerned and developed due to highly flammable characteristics of fabrics and environmental protection issues. Phytic acid (PA) was optimized as a common flame-retardant relying on its environmentally friendly and flame retardant characteristics. However, the strong acidity of PA always results in the loss in mechanical properties of the fabric. Herein, a synergetic strategy by compositing PA and ethanolamine (ETA) was proposed to enhance the flame resistance of the PA6 fabric. As a result, after the flame-retardant coatings prepared by the synergy of PA and ETA are impregnated on the surface of PA6 fabric, the limiting oxygen index (LOI) of PA6 fabrics increased from 21.2 % to 30.4 % with on a well mechanical strength retention rate (MSR) (more than 75 %), which is much better than the PA6 fabric treated by pure PA (LOI: 25.3 %, MSR: less than 40 %). The analysis results indicate that ETA not only reduces the damage of PA to PA6 fabrics but also plays an important role as a carbon and nitrogen source in the intumescent flame-retardant mechanism. This synergistic strategy provides a new reference for the development of environmentally friendly flame-retardant coatings.

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.
