“…The method of applying the protective composition affects the level of fire protection. The sol-gel method [21], layer-by-layer assembly [22], deposition of nanoparticles on the fiber surface [23], as well as chemical modification of synthetic fibers directly during their extraction from the melt [24] are most often used.…”

By introducing, in addition to phosphorus, nitrogen and halogens into the structure of the organosilicon compound, a synergistic effect of the flame retardant effect of the fabric is achieved, but the issue of protecting the environment from the effects of thermal decomposition products of the flame retardant composition arises. In view of the numerous publications on the impact of thermal destruction products of flame retardants on the ecological state of the environment, the problem of finding safe types of flame retardants that do not release toxic decomposition products during thermal destruction has arisen. The aim of the work was to develop a phosphorus-and nitrogen-containing silicate fire-retardant composition based on safe components that do not produce toxic products during thermal destruction of the treated fabric. As a result of the conducted research, it was established the possibility of using modifying additives (orthophosphoric acid and ammonium dihydrogen phosphate) in the composition of protective sol based on liquid glass. It was established that the introduction of small additions of orthophosphoric acid into the SiO2 золь сприяє утворенню суцільних тонких кремнеземних плівок на поверхні волокон ниток бавовняної тканини та значно збільшує час початку руйнування тканини під дією вогню. Позитивний результат досягався за умов одноразового просочування золем низької концентрації (8% SiO 2 ). Встановлено, що додавання дигідрофосфату амонію також позитивно впливає на підвищення вогнезахисних властивостей тканини. Оптимальний діапазон концентрації розчину фосфоровмісної добавки становить 10-15%. Додаткове просочення вогнезахисним розчином підвищує вогнестійкі властивості текстильних матеріалів і перешкоджає остаточному прогоранню і тлінню.

“…Because of its comfortableness, hydrophilicity, softness and air permeability, cotton fabric is an important bio-based textile over the world [4][5][6]. However, cotton fabric is easy to be ignited and its flammability is rapid, which seriously limited the application of cotton fabric [7][8][9].…”

Alginate fiber, a kind of bio-based fiber, is a type of inherently flame retardant material. Can the addition of alginate fiber to cotton fiber improve flame retardancy of prepared cotton/alginate fabric? To solve this question, in the present work, flammability and thermal degradation properties of the cotton and cotton/alginate fabrics were studied by thermogravimetric analysis (TG), microscale combustion calorimetry (MCC), cone calorimeter (cone) and thermogravimetric analysis coupled with Fourier transform infrared analysis. Compared to cotton fabric, TG results showed that the addition of alginate fiber decreased initial degradation temperature (T initial ) and maximum-rate degradation temperatures (T max ) of cotton/alginate fabric; however, the addition of alginate fiber improved the char residual amount at higher temperature. MCC and cone results indicated that the addition of alginate fiber reduced the peak heat release rate value and total heat release, showing improvement on flame retardant properties of cotton/alginate fabric. The release amounts of inflammable gases, such as H 2 O, for cotton/alginate fabric, were almost the same as cotton fabric in the thermal degradation process; however, compared to cotton fabric, the release amounts of flammable gases, such as compounds containing -C-H groups, alcohol, compounds containing carbonyl groups and ethers, were reduced. On the basis of the results mentioned above, the flame retardant properties of cotton/alginate fabric were enhanced. The results obtained in the present study can supply a flame retardant method by the addition of inherently bio-based flame retardant alginate fiber to flame-retard cotton fabric and enlarge the applied fields of alginate fiber.
