There are the fiber flame retardant and the after finished flame retardant. Because the cost difference, the after finished flame retardant treatment is widely used in China. The two way to make the fabric flame retardant, 1. Add the fire retardant chemicals to the fiber by polymerization, blended, alloying, composite spinning, melt grafting to make the fiber flame retardant. 2. The coated flame retardant or padded the flame retardant chemicals to the fabric. This two way have two different flame retardancy. The best way is to make the modified treatment to the fabric by nano technology, which have low cost and permanent flame retardancy. And the fabric is also soft, which have get the world class standard. In general, the fiber flame retardant can take full advantage of the FR chemicals than the after finished FR fabric. It is more softer and have permanent flame retardant effects. But in the practive use, we usually use more than one chemicals or two kind of method at the same time to get the flame retardant effects. By YULONG textile
Without knowing which chemicals you are talking about the answer is very complicated
A flame is a chemical reaction between two or more chemicals that produces heat and light and other chemicals, (products of combustion), For a constant flame to be maintained then there must be a method of renewing the supply of the two or more chemicals. (usually convection)A typical example of a flame, is a candle. This is usually a rod of wax with a central wick, the wick is ignited, heat from the flame at the wick melts the wax the now liquid wax is absorbed by the wick, and through capillary action the wax (fuel) is a fed to the flame. The heat from the flame causes a column of hot gases to rise Upwards and away from the candle, thus removing the product of combustion from the area and drawing in a fresh supply of oxygen which combines with the fuel in the flame to produce more heat, continuing the process.-----------------------------------------On the InternetIn internet usage, a flame is a insult, usually lengthy, about what a user has posted and generally doesn't hold any real information.CommentaryI like this question because of this interesting fact I discovered recently. A match will not burn in zero gravity. Experiments with matches on the space station showed that they extinguished themselves shortly after ignition because the gases produced by the combustion remain around the flame, cutting off the oxygen supply to the flame thus extinguishing it.
If nothing is added to the mixture and no flame is introduced externally it is called spontaneous combustion.
Lithium, strontium and calcium have red flames.
The two chemicals fizzle and burn through the surface they've been mixed on.
Using a double flame candle provides more light and heat compared to a single flame candle, making it ideal for larger spaces or for creating a cozy atmosphere. Additionally, the two flames can help the candle burn more evenly and last longer.
The blue flame represents complete combustion, where there is sufficient oxygen for the fuel to burn entirely, resulting in a hotter flame and fewer pollutants. In contrast, the yellow flame indicates incomplete combustion, where there is insufficient oxygen, leading to a cooler flame and the production of soot and other pollutants. This difference in combustion efficiency affects both heat output and environmental impact.
Strontium and lithium are two elements whose compounds burn with a red flame and are commonly used in fireworks and signal flares. The strontium compound strontium nitrate and the lithium compound lithium carbonate are examples of substances that contribute to the red color in pyrotechnics.

The chemical change causes the color change when the two new chemicals combine.
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
