Polyester cotton fabric is well received by consumers due to its excellent

 performance and durability. However, because of its easy combustion, it

 can cause fire accidents and lead to huge losses. Therefore, the research

 of flame retardant finishing has received widespread attention. So far, it

 has been found that the flame retardant finishing of polyester cotton fabric 

is far more difficult than the flame retardant of any component.

The main reasons are as follows: (1) the mutual heat induction of two

 polymers of polyester and cotton or their cracking products accelerates

 the spillover of the cracking products, so the ignition speed of polyester

 and cotton fabric is much faster than pure and pure cotton; (2) during

 the combustion process, the flame retardant will migrate between the 

two components of polyester and cotton, and therefore, it is also given

 to the polyester and cotton fabric. The flame retardancy caused difficulties; 

(3) because cotton is a non melted and non shrinkage flammable fiber,

 when the polyester and cotton products burn, the cotton fibers carbonized,

 a kind of scaffolding similar to the candle core, which hinders the droplets

 of polyester from the fire source; (4) the polyester and cotton blended 

fabric is heated and fused. It covers the surface of polyester fiber, and 

the polyester fiber and its pyrolysis carbon form a skeleton to prevent the

 shrinkage of the fabric, causing the melt polyester to become a fuel in the

 fire area, making the fabric more intense.

Therefore, to reduce the flammability of polyester and cotton fabric, it is 

necessary to do the following points: (1) when the blended fabric is flame-retardant

 finishing, the self suitable flame retardant is used, its effect is the most 

complementary or non interference; (2) eliminate the skeleton effect and 

the interference of two groups; (3) each group of blended fabric should be

 flame-retardant.






For a long time, the flame retardant finishing technology and flame retardant 

properties of polyester cotton fabric have been difficult to meet certain 

requirements. The main problem is that the handle or mechanical strength of 

the finished fabric is not satisfactory. Secondly, the production ecology needs

 improvement. At present, flame retardants and finishing processes which can

 effectively resist two kinds of fibers are not well found. The current application

 is more than 10% of diphenyl diphenyl ether, but it has the property of coating

 finishing, and the handle is not very ideal. Up to now, the flame retardance of

 polyester and cotton fabrics in China is still under study.
