Cotton Fabric Flame Retardant CP​

Cotton Fabric Flame Retardant CP

Chemical Name:Thrihydroxymethyl Azye-3-Oxopropylphosphonate

Physical  and  Chemical properties:

This product is colorless or light yellow viscous liquid and light piquancy. It is organic phosphoesterseries flame retardant with both phosphor and nitrogen flame retarding elements. Because of the cross link of active N-methylol and fabric, the flame retarding is permanent. It can get new textile product with flame retarding and water-proof or oil-proof and multi-functional when used with other addictives. It is one of the most representative products in its series.
It can be mixed with water by any proportion, and it is slight cationic in acidic condition. The impact of color and density to most dye material is light, nearly nontoxic.
This product is 80% water solution,easy to use and good flame retarding effect on cotton fabric. Strong washability and comfortable hand feeling.

Product Features:

1. Good flame retarding effect on cotton fabric.
No continued burning or smolder occurs after flame retardant treatment. It can reach higher than GB5455-85 B2 grade. Tested by consumer, it can reach UK BS3210. TY-2500-0009, DOCFF3071 standard.
2. Strong washability. No change on flame retarding effect even after 30-50 times washing.
3. Good intermiscibilitywith other additives.
4. Easy to confect.
5. Can be used on common machines, no need for any special machine.
Quality Specification:
Appearance:Colorless or light yellow viscous liquid.
Solid Content(%): ≥80%


CP is widely used in cotton, linen, viscoseand other fiber fabric. It requests a good pretreatment on the raw material to be even, clean and transparent. And the amount of wetting agent should be appropriate. When it is used with etherification multihydroxymethyl Melamine resin, the flame retarding and waterability can be both better. It is mainly used in military cloth, tent, curtain, decorative cloth, bedding and work clothes of metallurgy, fire fighting, mining area. It is also widely used in paper making.

Application Method:

1. Formula:CP 380~400g/L
6MD Resin 80~100g/L     Phosphoric Acid 18~20g/L
Softener 20~40g/L      Penetrant JFC 0~3g/L
2. Flame retarding technique process for reference:
Cotton fabric→ Padding(dip twice and rolling twice,Mangle expression 65~70%)→Drying(105℃′5minutes)→Baking(155℃′4minutes,165℃~170℃/2~3minutes)→Neutralization(Pure soda ash 50g/L,20~30℃)→Soaping (Pure soda ash 2g/L, Soap powder 3g/L, 60℃′3minutes)→Water washing→ Drying


(1) The formula and technique above could be adjusted according to fabric variety and practical condition.
(2) Trial test is necessary when adding other additives.
(3) It could slightly impact to some dye material, a trial test for colored light changing is requested before manufacture
(4) The baking temperature and time is the key point for the fasten rate of flame retardant. Too low temperature will weaken the washability and flame retarding effect.
(5) The fabric should be alkali washed and water washed in time after baking, to avoid weakening the fabric fastnessand flame retarding effect.
