“…[11][12][13] The ame retardancy mechanism of these phosphorus-containing copolyesters is based on the removal of heat from the burning process, which results in an increase of the melt-dripping. 14,15 Additionally, the conict between the ammability and the melt-dripping characteristics presents a major limitation in the practical application of the ame-retardant polyester.…”

“…To determine the antibacterial activity of coated CT fabrics, the antibacterial activity of the uncoated and coated CT fabrics was evaluated by a direct contact method with Gram-positive ( Staphylococcus aureus ) bacteria in an agar medium to form inhibition diameters. 46,47 As shown in Figure 9, the coated CT fabric showed an efficient inhibition diameter against S. aureus compared to the uncoated CT fabric (diameter = 0 mm). The -NH 3 + in DL can adsorb anionic substances after penetrating the cell, thus killing the bacteria by interfering with the normal physiological activities of the cells.…”

There are many defects in the post finishing flame-retardant modification of polyester–cotton (CT) fabric, leading to shortcomings such as single function and low flame-retardant efficiency, which still need to be solved urgently. Herein, a bio-based flame-retardant and antibacterial coating consisting of phytic acid and DL-arginine was deposited on CT fabrics using layer-by-layer assembly to obtain a flame-retardant and antibacterial CT fabric. Fourier transform infrared spectroscopy confirmed that the assembled coating was successful deposited on the CT fabric. The thermogravimetric analysis revealed that the number of bilayers had no significant effect on the degradation temperature of the coated CT fabric; however, it significantly improved the charring effect of the sample, wherein the char rate of the CT fabric coated with 20 bilayers increased from 0.11 to 8.67 wt% compared with uncoated CT fabric at 700°C. In addition, the limiting oxygen index of the CT fabric coated with 20 bilayers increased to 32.0 ± 0.3%. Furthermore, the vertical results revealed that the CT fabric coated with five bilayers attained the UL-94 V-1 grade. The heat release rate (HRR) and the total heat release (THR) of the coated CT fabric were significantly decreased compared to those of the uncoated CT fabric. In particular, the HRR and THR of the CT fabric coated with five bilayers reduced by 28.97% and 30.49%, respectively. Furthermore, the coated CT fabric exhibited an obvious antibacterial effect on Staphylococcus aureus, and the inhibitory ring increased from 0 to 4.0 mm with an increase in bilayers to 20. This study describes a facile method of flame-retardant and antibacterial modification of CT fabric using biological materials.

Flame Retardancy of Nylon 6 Fibers: A Review

et al. 2023

View full text Add to dashboard Cite

As synthetic fibers with superior performances, nylon 6 fibers are widely used in many fields. Due to the potential fire hazard caused by flammability, the study of the flame retardancy of nylon 6 fibers has been attracting more and more attention. The review has summarized the present research status of flame-retarded nylon 6 fibers from three aspects: intrinsic flame-retarded nylon 6, nylon 6 composites, and surface strategies of nylon 6 fibers/fabrics. The current main focus is still how to balance the application performances, flame retardancy, and production cost. Moreover, melt dripping during combustion remains a key challenge for nylon 6 fibers, and the further developing trend is to study novel flame retardants and new flame-retardancy technologies for nylon 6 fibers.
