Because of increasing public awareness and strong legislative regulations, the production of nonflammable textile fabrics is essential. Generally, phosphorous-nitrogen polymers are very effective fire retardants, especially when applied to cotton fibers. Since many fabrics marketed today are blends of cotton and synthetic fibers, flame retardants that are compatible with these blends must be developed.Preliminary research on blended cotton-polyester fabrics treated with a mixture of tetrakishydroxyethylphosphonium chloride (THPC) urea, trimethylolmethylglycoluril (TMMGU), and polyvinylbromide (PVBr) has produced a flame retardant finish that is durable through 60 laundry cycles. This mixed emulsion was padded onto the fabric, dried, and heat cured to polymerize in situ on the surface and within the fibers. The polyvinylbromide was added because bromine compounds are known flame retardants and polyester has an affinity for polyvinylbromide.

An intumescent flame retardant (IFR) containing phosphorus and APP was applied to polyester fabric. The finishing process was optimized and the properties of treated fabric were characterized. The optimum process was as follows: the total dosage of IFR system was 40%, the mass ratio of phosphorus-containing flame retardants and APP was 7:3, and curing temperature was 180°C. The treated PET fabrics imparted good resistance to melt drop. Characterization of the thermo-gravimetric analysis, differential scanning calorimetry (DSC) indicated that much more residual char with intumescent structure, the incombustible gas and water were formed during combustion of flame retardant polyester fabric, whose decomposition temperature was lower compared to that of the untreated sample.

A flame-retardant polyester fabric was obtained by eco-friendly water-based polyurethane adhesive for coating, which was made of waterborne polyurethane and several flame retardants. It was found that the combination of Doher6206 and MCA is an effective flame retardant. The concentrations of the combination and polyurethane as well as the process conditions were optimized. The optimize result was gained while the cure temperature was 150°C, cure time was 3 min, coating width was 0.1mm and coating rate was 4.15 m/min. Because of the good performance in flame-retardant and eco-friendly, the flame-resistant polyester fabric has the potential to be used in the inner decoration of the car and the plane, curtain, and the inhibitor of baby car and so on.

Abstract Failures in printed circuit boards account for a significant percentage of field returns in electronic products and systems. Conductive filament formation is an electrochemical process that requires the transport of a metal through or across a nonmetallic medium under the influence of an applied electric field. With the advent of lead-free initiatives, boards are being exposed to higher temperatures during lead-free solder processing. This can weaken the glass-fiber bonding, thus enhancing conductive filament formation. The effect of the inclusion of halogen-free flame retardants on conductive filament formation in printed circuit boards is also not completely understood. Previous studies, along with analysis and examinations conducted on printed circuit boards with failure sites that were due to conductive filament formation, have shown that the conductive path is typically formed along the delaminated fiber glass and epoxy resin interfaces. This paper is a result of a year-long study on the effects of reflow temperatures, halogen-free flame retardants, glass reinforcement weave style, and conductor spacing on times to failure due to conductive filament formation.
