Flame retardant bathing simultaneously with dyeing

Okonon DK31

Okonon DK31 is non-halogen organophosphorous compound anti-flammable processing agent. It is a type diffused into the water. It is effective for the polyester or CDP textile. In addition, it has the physical properties applicable to internal decoration on the automobile. Very excellent anti-washing nature can be granted by dyeing or processing with vacuum suction on polyester fabric. It is not the generally used liquid type but powder type flame retardant which is characterized with fastness to light required for the automobile.
Stability Okonon DK31 passed the PBBs & PBDEs & heavy metal tests. It is non-halogen and non-formalin, and dioxin is not created during burning. A defect improved product such as changing to yellow after processing and odoring.

Process scouring firstly certainly before performing the inflammability processing (to stabilize the performance).



Use after agitating fully as the product can be separable. 



Decide after performing appropriate pre-test because the use amount is differed depending on the fabric type and required physical properties. 



Decide to use after appropriate performing pre-tests because the inflammable performance is reduced when this product is treated on the antifoulant processed fabric.  Decide after performing appropriate pre-tests for the fabric processed with softener. 



Use this chemical after verifying certainly because it can reduce the fastness such as light resistance, heat resistance, water sign, whitening, chalk mark, discoloring, frictional coloring and embossing depending on the treatment methods. 



Perform the post processing (Embossing and etc.) of this chemical certainly after verification.



Check the compatibility and stability fully in case of mixed using with other chemicals.  



Keep certainly under the room temperature by avoiding the direct sunlight because it can be frozen in case of keeping under -4℃.



Seal with the cap certainly during or after use.
