Flame-retardant finishing is also called fireproof finishing. The finished fabric is not easy to burn and extinguishes fire. At present, the flame retardant finishing agent developed at home and abroad is a compound containing elements such as phosphorus, nitrogen, chlorine, bromine, antimony and boron.

For chemically bonded nonwovens, flame retardants are typically added to the adhesive or used as a non-combustible binder. For the non-woven fabric(Flame Retardant Nonwovens Supplier) directly made of filament, a flame retardant can be added during the spinning process, and the flame retardant effect can be obtained after the fixing is completed. Other types of nonwoven fabrics(Flame Retardant Nonwovens Supplier) may be flame retardant by finishing or blending a certain amount of flame retardant fibers into the fabric. But in general, post-cleaning is the quickest and most convenient way.

For disposable products(Flame Retardant PP Non-woven Fabric Vendor), temporary flame retardant finishes such as ammonium sulfate, borax and boric acid, ammonium chloride and zinc sulfate, alum and ammonium phosphate, aluminum sulfate and sodium silicate can be used in combination after drying and then baked.

A product requiring a long-term flame retardant effect can be obtained by mixing a durable flame retardant(Flame Retardant Spunbond Nonwovens Wholesale) finish such as phosphoramide, diammonium phosphate and urea, titanium chloride and trichloride. When two or more flame retardants are used in combination, a synergistic flame retardant effect can be obtained. Permanent flame retardant finishing agent generally needs to be washed more than 50 times.
