Flame retardant finishing of cotton fabrics is developing very quickly, the current domestic mature, flame retardant can be basically self-sufficient, to industrial production. Flame retardant finishing of cotton durability generally have the following three methods:
A.Proban / ammonia fumigation, Proban method is a British Wilson company first used in industrial production, the traditional Proban method is flame retardant THPC (four hydroxy methyl chloride Fang) padding post curing process, the improved method is smoked Proban / ammonia process, the process is: the padding of flame retardant finishing, drying, ammonia, oxidation - water washing and drying. Domestic plan Beijing Guanghua, Jiangyin printing and dyeing factory, Anshan textile factory and other auxiliaries and equipment introduction of foreign production. This is the process of the currently accepted good flame retardant effect, fabric strength reduction of small, feel less affected. But because the equipment has limited its popularization.
B.Pyrovatex CP finishing process. The flame retardant performance of the product is good, good durability, resistant to family washing 50 times even 200 times more, feel is good, but the strength decreased slightly larger. Domestic use of this kind of flame retardant manufacturers two, thirty.
C. Cotton temporary, semi durable flame retardant finishing fire retardant, electric blanket, wall cloth, sofa cloth fabric washing degree is not very high, this kind of product to do temporary or semi durable flame retardant finishing can be. That is, the ability of 1 - 15 times gentle washing, but not resistant to washing soap. There are mainly borax, boric acid, diammonium hydrogen phosphate process technology, phosphoramide process, dicyandiamide process etc.. The application of the process of industrialization in cotton fabric production is not much.
