Desired for manufacturing research institutes, hospitals or other commercial facilities. In some countries, the use of flame retardant bedding fabrics in facilities such as hospitals, nursing homes, psychiatric institutes, prisons, universities, etc. is required by law.

Flame retardancy is determined by hydrating boric acid in cotton-heavy fabrics, such as A, C, A, and striped pine tress cover fabrics).
This was achieved by treatment with IJium compounds. This sodium borate treatment not only reduces the velocity of flame travel through the fabric foil, but also removes the external flame source such that the treated fabric foil itself is unable to substantially support the flame. , it serves the reconsideration function of attaching self-extinguishing properties to cloth.

In addition to being flame retardant, in many applications it is desirable for the fabric foil to be bacteriostatic and/or removable and water resistant. Treated cloth foils that have both of these properties are

The coating formulation is prepared by first adding the polymeric carrier, antimony pentoxide and aluminum trihydrate to about 50% of each component in water.
It is prepared by mixing together in the form of a 0% dispersion. Although aqueous solvent systems are preferred because they do not pose the environmental hazards associated with more volatile solvent systems, other compatible solvent systems can be used. Additionally, polyvinyl chloride or vinyl chloride vinyl acetate plastisols can be used.

Preferably, prior to dispersion in water, the aluminum trihydrate is ground in a mill to reduce the average particle size of the aluminum trihydrate to less than about 10 microns. The aluminum trihydrate is then dispersed in water in the presence of about 1% by weight (based on the dry weight of the aluminum trihydrate) of the dispersion. Examples of suitable dispersants are nonionic dispersants, or trisodium phosphate or other compatible dispersants.

A plasticizer and a bactericide and/or a disinfectant are then added to the aqueous dispersion of polymeric carrier, flame retardant and aluminum trihydrate. Before coating the formulation onto the textile base, the viscosity of the formulation is adjusted by addition of suitable thickeners.
