“…In recent literature also, finishing the process with polyhedral oligomeric silsesquioxane and bohemite nanoparticles has been exploited for enhancing the thermal stability and flame retardancy of cotton fabrics [39]. Cellulose-based materials can be strongly affected by the presence of a protective phosphorus-rich silica coating obtained with a sol gel approach [40]. A one-way between samples ANOVA was conducted to compare the effect of CSE treatment at different pH and concentrations on LOI in untreated cotton, CSE-treated cotton at pH 4.5, 7, and 10 conditions at original concentration (CA) extract and concentrated levels (CB) (refer Figure 4(a) and (b)).…”

As far as the value addition of textile is concerned, flame retardancy of textile materials is considered to be one of the most important properties in textile finishing by both industries as well as academic researchers. Flame-retardant property with thermal stability was imparted to cotton by using green coconut (Cocos nucifera Linn) shell extract, a natural waste source of coconut. Coconut shell extract was analyzed by high-performance liquid chromatography, Fourier transform infrared spectroscopy, energy-dispersive spectrometry and its phytochemical analysis was also carried out. The coconut shell extract (acidic after extraction) was applied in three different pH (acidic, neutral, and alkaline) conditions to the cotton fabric. Flame-retardant properties of the untreated and the treated cotton fabrics were analyzed by limiting oxygen index and vertical flammability. The study showed that all the treated fabrics had good flame resistance property compared to that of the untreated fabric. The limiting oxygen index value was found to increase by 72.2% after application of the coconut shell extract from alkaline pH. Pyrolysis and char formation behavior of the concerned fabrics were studied using thermogravimetric analysis and differential scanning calorimetric analysis in a nitrogen atmosphere. The physicochemical composition of the untreated and coconut shell extract treated cotton fabrics were analyzed by attenuated total reflection-Fourier transform infrared, scanning electron microscope, and energy-dispersive X-ray spectroscopy. Also, treated cotton fabric showed natural brown color and antibacterial

“…Эти покрытия способны защищать поверхность, тем самым улучшая обычные характеристики обработанных материалов, таких как огнестойкость [18][19][20], супергидрофобность [21][22][23][24][25][26], защита от противомикробного воздействия [27,28], ультрафиолетового излучения [29]. Для повышения огнезащитных свойств обработку текстильных материалов проводили с применением 1,2,3,4-бутантетракарбоновой кислоты, гипофосфита натрия, гидрат N-(фосфонометил)иминодиуксусной кислоты, моноэтаноламина, в качестве зольгель-предшественника использовали: тетраэтоксисилан, 3-аминопропилтриэтоксисилан, 3-глицидоксипропилтриэтоксисилан [30][31][32][33]. Гибридные покрытия, содержащие фосфор, кремний и азот нанесены на хлопчатобумажную ткань посредством золь-гель-процесса для улучшения огнезащитных свойств [34].…”

The article presents studies on the use of a new composition based on sodium silicate, urea and sodium hydrogen phosphate to impart fire-retardant properties to cellulosic textile materials. The influence of the concentration of the starting components, temperature, and heat treatment time on the flame retardant properties was studied. The change in the fire retardant properties of cotton fabric is given for three heat treatment modes: at 80, 90 and 100 °C. Compared to the initial fabric, the samples treated with a flame retardant have indicators of flame retardant properties. Untreated fabric with a size of 220×170 mm when tested for flammability at an ignition time of 15 s completely burns out in 60 s. In samples treated with a flame retardant, at an ignition time of 15 s, the smoldering time is practically reduced to zero. With an increase in the concentration of the flame retardant, and the temperature of the heat treatment, the loss of material strength, breaking load, and the appearance of the fabric change slightly. Using electron scanning microscopy and energy dispersive microanalysis, it was shown that pure cotton fabric contains 68.77% carbon and 31.22% oxygen; after modification, particles of sodium – 0.02%, phosphorus – 0.04% and potassium – 0.05% are formed on the surface of the treated fabric. distributed fairly unevenly. It has been shown that in cellulosic materials modified with compositions based on sodium silicate and urea, sodium hydrogen phosphate, flame retardant properties increase. The proposed composition provides the achievement of higher fire resistance. Processing can be carried out on standard equipment of finishing enterprises without the stage of high-temperature fixation of the drug.

“…Thermal shielding effect of silica phases and char-forming by synergistic effect of phosphorous and nitrogen were attributed to be the causes of flame retardancy and thermal behavior of cotton samples. However, the LOI values of fabric samples reduced from 29 to 21 after one washing process [9].…”

“…Grancaric et al [9] studied the flame retardancy properties of cotton fabric by using diethylphosphatoethyltriethoxysilane (DPTES) as a sol-gel precursor together with monoethanolamine (MEA) as a neutralizer for acidic conditions of DPTES with or without the addition of tetraethoxysilane (TEOS) and 3-glycidoxypropyltriethoxysilane (GPTES) to increase the durability of finishing process. Their results showed that the cotton samples were in self-extinguished classification and had the LOI (limited oxygen index) value of 29.…”

In the chapter, sol-gel applications in textile finishing process such as flame retardancy, water, oil repellency, ultraviolet (UV) protection, self-cleaning, and antibacterial and antiwrinkle processes are reviewed. Sol-gel technology is well known in materials, metallurgy, ceramic, and glass industry since 1960 and has been researched in textile industry in the last decade. Sol-gel technology has some advantages when compared to conventional textile finishing process. Sol-gel technology, which is a method applied to the inorganic metal alkoxide or metal salts to organic textile materials, could impart the high, durable activity and multifunctional properties to different textile materials in the same bath at one step using low concentration of precursors. In addition, sol-gel technology presents alternatively economical, ecological, and environmental friendly process due to one-step application, using low concentration of chemicals, nonhalogenated chemicals, and nonformaldehyde release when compared to conventional processes.
