Synthesis and Application of a Polyamide-containing Phosphorous and Sulfur Flame-retardant for Nylon Fabric
E-mail:
Monomer of polyamide (PA66) and flame-retardant intermediate product (FR) were firstly synthesized, and the flame-retardant (PA-FR) was further gained by polymerization of PA66 and FR. The structure of PA-FR was confirmed by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR), X-ray photoelectron spectroscopy (XPS), and gel permeation chromatography (GPC). The thermal properties of PA-FR and the finished fabric were evaluated by thermal gravity analysis (TGA) and differential scanning calorimetry (DSC). Moreover, X-ray diffraction analysis (XRD) showed that melting eutectic reaction occurred between PA-FR and nylon fabric. The experimental results showed that the limiting oxygen index (LOI) value of PA-FR treated fabric and PA-FR treated fabric after 10 laundries were improved to 28.8% and 26.4%, respectively. It implied that PA-FR had a good and durable function of imparting fire-resistance to nylon fabric.
