Comparison between the selected hydroxides of groups IA and IIA as flame retardants for cotton fabrics

Abstract

A comparative effect of selected hydroxides of groups IA and IIA on the flammability of a cotton fabric has been studied. The optimum loading of an alkali metal hydroxide required to retard the flame diminishes with increasing its molecular weight, while the opposite situation is observed for alkaline earth hydroxides. Explanation of these results is suggested with due regard for the thermal analysis data and existing theories of flame retardation.

Flame-resistant polymeric composite fibers based on nanocoating flame retardant: thermogravimetric study and production of α-Al2O3 nanoparticles by flame combustion

“…A vertical flammability test method similar to the procedure described in DOC FF3-77 (U.S. Department of Commerce Standard) [22] was used. The full description of flammability testing has been demonstrated in previous investigations [23][24][25][26][27][28][29][30][31][32][33]. Briefly, specimens of size 220 mm × 80 mm were conditioned for 24 h at a relative humidity of 65 ± 2% and an average temperature which ranged between 20°C and 22°C prior to their evaluation.…”

Flame‐retardancy of a Cellulosic Fabric by the Application of Synergistic Effect between Ammonium Bromide and Antimony(III) Oxide

“…The apparatus has been designed and named as a Mostashari's flammability tester ( Figure 1) and introduced in the previous articles. [11][12][13][14][15][16][17][18][19][20][21] It is a rectangular aluminum frame cut on from one of its smaller sides and has inner grooves for inserting the fabric. The frame includes five even numbers of holes in each of its parallel legs so that pinning of the fabric could be possible inside it.…”
