What is the cotton flame retardant fabric? Flame retardant polyester cotton fabric finishing the key and difficult? Cotton flame retardant fabric price?

Cotton fabric due to excellent wearability and durable, welcomed by consumers. However, due to its easy to cause fire accidents, and cause huge losses, so the research of Flame retardant finishing has been widely concerned. So far, people found that the flame retardant on cotton fabric finishing than the flame retardant component to any difficulty.
The main reasons are:
Heat A, polyester and cotton blended fabric, polyester group heating molten covered on the surface of polyester fiber and polyester fiber and its pyrolysis carbon will form the skeleton, prevent the fabric shrinkage, resulting in molten polyester as a fuel ignition zone, make the fabric more severe burning.
B, in the process of combustion, flame retardant polyester and cotton will transfer, in between the two components so to flame retardant cotton fabric is difficult;
Each heat C, polyester and cotton two polymers or their cleavage products induced, accelerate the pyrolysis products of overflow, so the ignition speed than the pure cotton fabric and polyester cotton is much faster;
D, because cotton is a kind of melt without shrinkage flammable fibers, polyester products when burning, cotton fiber carbonization, play a support role similar to the wick of polyester, polyester and hinder the droplet from fire;

Therefore, to reduce the flammability of cotton fabric, need to do the following:

A, elimination of skeleton effect and interference of two components.
B, blended fabric in each component should be flame retardant;
When C and blended fabrics are flame retardant finishing, they are suitable for each other;
At present, can be durable and can meet the requirements of flame retardant performance, CVC Flame retardant fabric is the first choice, the fabric by more than 60% of cotton fiber, polyester fiber blend of less than 40%. Excellent properties of two kinds of cotton and polyester fibers. With good strength and better crease resistance and durability.
For a long time, has been the development of flame retardant polyester fabric finishing technology and its flame retardant properties could not meet the application requirements. The main problem is the finishing of the fabric handle or mechanical strength is not satisfactory; secondly, the production of ecological aspects need to be improved. At present, it has not been able to find a good flame retardant and finishing process for two kinds of fibers at the same time. The more is the application of decabromodiphenyl oxide, but it has the property of coating, feel is not very ideal.
