“…In the recent decades, one of the main reasons for residential home fires is the ignition and combustion of house decorations and furnishing [10]. Thus, increasing types of flame retardants have been explored to improve the flame retardant properties of cotton fabric, such as phosphorus- [11,12], nitrogen- [13,14] and silicon-containing [10,15,16] flame retardants.…”

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.

“…These flame retardants possess good thermal stability, low fire hazard, and biological compatibility [17,18]. It is elucidated that these compounds produce siliceous char layer which delays the spread of fire and causes a remarkably larger reduction in materials' flammability during combustion [19,20], especially coupled with other flame-retardant elements [18,[21][22][23][24]. Therefore, silicone-based compounds have great potential as flame inhibitors for cotton fabrics, and it is of interest to develop eco-friendly new flame retardants containing Si, P, and N elements [25,26].…”

A novel flame-retardant agent, nitrogenand phosphorus-containing polysiloxane [(IB-co-N-MDPA)PDMS] was synthesized, and it was employed on cotton fabrics. Cone calorimeter testing showed that the treated cotton fabric with (IB-co-N-MDPA)PDMS became less flammable with longer time to ignition and lower value of HRR, THR, EHC and mass loss. Thermogravimetric analysis demonstrated that (IB-co-N-MDPA)PDMS improved the thermal and thermo-oxidative stability of cotton fabric with fewer flammable volatiles, and more char is produced during combustion. Scanning electron microscopy showed that the surface of treated cotton fabric after combustion was covered by a compact char layer which indicated that (IB-co-N-MDPA)PDMS favored the formation of char as evidenced by the FTIR of residues. Furthermore, EDS analysis results demonstrated that the concurrent presence of Si and P in flame retardant effectively enhance the flame retardancy of cotton fabric with the remarkable amount of Si and P elements that were still present on the surface of fibers after combustion.

“…This improving is due to chemical reactions between epoxy ring of GPTMS and hydroxyl groups on the cotton surface.

Biopolymer/chitosan/silan composite wassynthesized in four form by conjugating of chitosan with different biopolymer compounds namely, β-Cyclodextrin (β-CD), Arabic gum, Guar gum and Pullulan in presence of 3-glycidoxypropyltrimethoxysilan (GPTMS) as a cross-linker. Characterisation of the prepared composites has been done through some measurements. FT-IR confirmed the chemical reactions between biopolymers, chitosan andGPTMS.TEM and particle size confirm that, the particles are in small size ranged from 20 -200 µm and have porous structure. Textural properties of the prepared composites were studied and provide that, the microgel with pullulan have the best texture properties than other gels, and gel with guar gum have a worst texture properties. Studding the pH effect found that, the microgels particle size was changing with increasing/decreasing the temperature. The flow properties of the chitosan based microgels at different concentrations and different temperatures were also determined. Treated fabrics with chitosan-based microgels were characterized for their morphological structure, antibacterial properties, water uptake for untreated and treated fabrics at different pHs and temperatures and it is confirmed that, the prepared composites impart a hydrophobicity property to the cotton fabrics.
