In this study, an attempt was made to investigate the flame retardancy of cotton fabrics coated with a high nano-ZnO content. Via a simply method in situ, a novel ZnO/cotton composite can be fabricated with a high proportion of nano-ZnO assembled on cotton fabric, where the finished cotton fabric has a certain property of flame retardancy. Discussed herein is the effect of the processed liquid concentration, ammonia-smoking time, and curing temperature on fabric properties such as flame retardancy and hand feeling. Performed were also tests of doping boric acid using the vertical burning method. The finished cotton fabrics were analysed using X-Ray Diffrcation (XRD) and a field emission scanning electron microscope(FESEM), which indicated that between the fibres, and inside the lumen and mesopores of the cotton fibres are assembled with nano-ZnO. The results show that the nano-ZnO content on cotton fabrics can reach up to 15.63 wt%, with the finished cotton fabric having excellent flame retardancy, despite the long after-glow time; however, doping with 0.8 wt% boric acid on the cotton fabric can markedly reduce this. Therefore, a high amount of nano-ZnO doped with boric acid assembled on cotton fabric has great potential in the future.

Purpose – The purpose of this paper is to develop the flame retardancy properties of cotton fabrics with treatment of phosphorus and nitrogen containing silane-based nanosol by sol-gel process. Design/methodology/approach – Nanosols containing tetraethoxysilane or (3-aminopropyl) triethoxysilane as precursors, (3-glycidyloxypropyl) trimethoxysilane as cross-linking agent and guanidine phosphate monobasic as flame retarding agent were impregnated on cotton fabrics. Flame retardancy properties of the fabric samples were determined by limited flame spread test and limited oxygen index (LOI) test. In addition, microstructural and surface morphological properties of the fabric samples were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscope. Findings – Depending on the limited flame spread test, the authors show that the coated fabric samples gain flame retardancy properties and the LOI value of the samples increased as to 45.7 per cent by the synergistic effect of phosphorus-nitrogen-silicon. Originality/value – There have some studies in flame retardancy behaviour of textiles. In this study, flame retardant cotton fabric with very low weight in grams was improved by sol-gel process. Moreover, ecological process was provided thanks to using halogen-free flame retardant.

Abstract In many plastic applications, improvement of the flame retardancy is a very significant topic. Polypropylene (PP) is used in many applications such as housing industry due to its cost performance efficiency. Enhancement of flame retardancy properties of PP is necessary in many applications. In this study, the investigation focuses on the synergistic effect of mica mineral and IFR in enhancing the flame retardancy properties of PP in order to achieve cost competitive solution, so as to provide that different/various ratios of IFR and mica mineral were added into PP to compose 30 wt% of the total mass of the polymeric compounds. The synergistic effect of mica mineral with IFR in PP was investigated by limiting oxygen index (LOI), glow wire test (GWT), UL-94 test, thermal gravimetric analyses (TGA), and mechanical tests. The results from LOI, UL 94, and GWT tests indicated that mica added to PP/IFR compound has a synergistic flame retardancy effects with the IFR system. When the content of mica was 6 wt%, LOI value of PP compound reaches to 34.9% and becomes V-0 rating (3.2 mm) in UL 94 flammability tests and compounds pass GWT tests both at 750 and 850°C.
