Calcium Borate Particles: Synthesis and Application on the Cotton Fabric as an Emerging Fire Retardant

Two types of fire retardant insulating wood-fiber boards have been developed in laboratory and mill scale. Both include treatments which are incorporated in the normal wet process for manufacturing such boards with a concentration of the fire retardant to one side of the board. One type involves addition of a calcium borate mineral, colemanite, to the top fiber layer of the board. Scandinavian class II and British class 1 are achieved. The other type involves addition of a pre-condensate of melamine-dicyandiamide-phosphoric acid mixed with a commercial phosporus-nitrogen compound on the wet lap. Scandinavian class I and British class 1 are achieved. The first type, colemanite, creates no problem in normal board production or in respect to product properties. It is readily suited to full scale application. The second type has a better fire classification but is accompanied by production and product problems, e.g. mildew growth at humid exposure, and needs further development. Both board types have been exposed in ceiling application for 8 years without any reduction in fire classification.

Abstract Egg white proteins (W) in combination with hypophosphorous acid (HA) were investigated for making flame retardant coating over cotton fabric adopting layer by layer (LbL) assembly technique. A novel phosphorous-nitrogen based non-inflammatory pathway was produced due to strong electrostatic interactions between egg white protein and HA. The coated cotton fabric was characterized using FESEM, ATR-FTIR, TGA and flame tests. Vertical flame test (VFT) and BS EN ISO 15025 tests were performed to understand the combustion pattern of coated fabric. The cotton fabric coated with egg white protein followed by HA (CTW+HA) showed self-extinguish properties with fragile char structure, whereas uncoated fabric was completely burnt with ash residue. Thermogravimetric analysis revealed that initial decomposition temperature of coated fabric got lowered but raised the char residue at 800 ℃. Moreover, surface morphology after VFT of CTW+HA showed swollen char structure that prevented the interaction of combustible products with oxygen and heat. Thus, the developed coating could serve as excellent fire retardant due to the synergistic effect of HA and egg white protein.

Fabric Finishing

A series of novel fire-retardant agents, fluorocyclotriphosphazene derivatives with the substitution groups of 2,2,3,3-tetrafluoropropoxy groups were synthesized using hexachlorocyclotriphosphazene and 2,2,3,3-tetrafluoropropyl alcohol as starting materials. The synthesized fire-retardant agent was emulsified and applied on the cotton fabric finishing to reduce the flammability and afford water/oil repellency simultaneously. The optimum finishing process was achieved according to the test of cotton finishing with fluorocyclotriphosphazene. The treated cotton showed not only excellent fire-retardant performance, but also water and oil repellency with little change in strength and whiteness.
