Flame retardant for cotton fabric

Flame retardant for cotton fabric

The development of the flame retardant of cotton fabric is very fast. At present, it is relatively mature in China, and the flame retardant of cotton fabric can be used to produce the flame retardant finishing of pure cotton. There are three methods:

A ﹒ Proban/ammonia fume process, the traditional method of Proban flame retardants is THPC (4 hydroxy methyl ammonium chloride) pad after curing process, the improved method is Proban/ammonia fume process, technological process is: the pad flame retardant finishing - drying - ammonia fume - oxidation - washing and drying. It is acknowledged that the flame retardant effect is good, the fabric is strong and small, the feeling affects less process. But the equipment problem limited its promotion.

B. PyrovatexCP finishing process. The flame retardant property of the product is good, the durability is good, but the family wash 50 times or more than 200 times, feel good, but the strength decrease slightly. The domestic use of this kind of cotton fabric flame retardant manufacturer has two or thirty.

Temporary, and durable flame retardant finishing cotton - electric blanket, wall cloth, sofa cloth fabric washes of flame retardant requirement is not high, this kind of product do temporary or half durable flame retardant finishing. Namely ability to endure 1 ~ 15 times warm water to wash, but not the soap wash. It mainly includes borax, boric acid process, ammonium phosphate process, phosphoric acid process, and dicyandiamide process. The above process is not used in the industrialization of cotton fabrics.

Wool has higher moisture regain and ammonia content, so it has better natural flame retardancy, but if higher standards are required, flame retardant finishing is required. The earliest wool flame retardant finishing is the use of borax and boric acid solution impregnating method, the product is used for the decoration cloth of airplane. This method is good in flame retardant, but not washable. After the 1960s, it was treated with THPC, and it was better to be washable, but the process was complicated, and the hands were rough, and the wool fabric was lost.

The method of international wool board study is to use titanium, zirconium and hydroxy acids to finish the wool fabric and get the satisfactory flame retardant effect without affecting the feel of the wool. Therefore, it is widely adopted. The main products are titanium, zirconium, tungsten and other metal complex finishing agents. Since the late 1980s, several units in China have studied the development of wool flame retardant and finishing process, and obtained satisfactory results.



Isopropylphenyl Phosphate(IPPP65) Uses:

Isopropylphenyl Phosphate, Flame Retardant IPPP65 Halogen-Free Phosphate Flame Retardant Plasticizer, Will Not Twice Pollute The Environment; In The Phosphate Ester Species Is A Viscosity, Phosphorus Content Is More Moderate A Model. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.


The composite wfr-866 series of flame retardants was developed by tianjin institute of synthetic materials, one of which was WFR-866F (the main component of fluorine complexes), and a WFR-866B (which was mainly composed of bromohydroxy acid).

The pure wool flame retardant fabric is mainly used in the aircraft cabins, high hotels and other carpets, curtains, and wall materials.

The flame retardant finishing of polyester fabric has not found a suitable ideal flame retardant so far. Triphosphate (2, 3-dibromopropyl) (TDBPP) has certain effect on dacron flame retardation, but it has a carcinogenic effect. Suitable for 100% polyester fabric, good effect and little toxicity. In addition to finishing agent containing bromine, antimony compounds, such as bromine biphenyl ether, ten hexabromocyclododecane, antimony trioxide, antimony pentoxide are studied, such as adhesive is added in the working liquid, the flame retardant adhesive on the fabric.

But overall, the finishing fabric flame retardant sex is still can, but the hand feels hard, there is frost phenomenon, color change and so on, the finishing fluid is not good. The main reason is that the flame retardant particle size is large, easy to gather and heavy, and the fiber adsorption is poor. According to the foreign introduction, the particle size is 15 ~ 20nm, the flame retardant effect can increase 3 times, the hand feels soft, washable is good.

Fire retardant protective clothing should be used in metallurgy, forestry, chemical industry, oil and fire departments according to national standard of flame retardant protective clothing. According to statistics, our country should use fire retardant protective clothing personnel in about 6 million, the market potential of flame retardant protective clothing is huge. The requirements for protective clothing vary from industry to industry.

In the steel industry, the quality of the flame retardant protective clothing is high, but the price is low, so most of the steel industry is still using cotton canvas or polyester flame retardant post-treatment work clothes. Because cotton work clothes wear comfortable, easy to handle, low price, still use widely. When the fire protection department is selecting fire retardant protective clothing, the first consideration is performance, and the price is only second. They require protective clothing with good flame retardant function, high tensile strength, especially small thermal shrinkage.
