“…Thermal deterioration of pristine cotton occurs mostly between 235 °C and 379 °C. Approximately 80% of the mass was lost at this step, which was attributed to the destruction of saccharide rings for cotton to produce glucose, which was then broken down into smaller molecular volatiles and residual chars [ 48 ]. The T 10% and T max of CH/APP cotton and CH/APP@TiO 2 -SiO 2 -HMDS cotton fabric samples were much lower compared with those of the pristine cotton fabric.…”

The hydrophilicity and inherent flammability of cotton textiles severely limit their usage. To solve these drawbacks, a superhydrophobic and flame-retardant (SFR) coating made of chitosan (CH), ammonium polyphosphate (APP), and TiO2-SiO2-HMDS composite was applied to cotton fabric using simple layer-by-layer assembly and dip-coating procedures. First, the fabric was alternately immersed in CH and APP water dispersions, and then immersed in TiO2-SiO2-HMDS composite to form a CH/APP@TiO2-SiO2-HMDS coating on the cotton fabric surface. SEM, EDS, and FTIR were used to analyze the surface morphology, element composition, and functional groups of the cotton fabric, respectively. Vertical burning tests, microscale combustion calorimeter tests, and thermogravimetric analyses were used to evaluate the flammability, combustion behavior, thermal degradation characteristics, and flame-retardant mechanism of this system. When compared to the pristine cotton sample, the deposition of CH and APP enhanced the flame retardancy, residual char, heat release rate, and total heat release of the cotton textiles. The superhydrophobic test results showed that the maximal contact angle of SFR cotton fabric was 153.7°, and possessed excellent superhydrophobicity. Meanwhile, the superhydrophobicity is not lost after 10 laundering cycles or 50 friction cycles. In addition, the UPF value of CH/APP@TiO2-SiO2-HMDS cotton was 825.81, demonstrating excellent UV-shielding properties. Such a durable SFR fabric with a facile fabrication process exhibits potential applications for both oil/water separation and flame retardancy.

“…The main stage for thermal deterioration of pristine cotton can be seen between 250 °C and 380 °C. Approximately 75% of the mass is lost at this step due to the breakdown of cotton's saccharide rings into glucose, which is subsequently broken into smaller chemical volatile substances and residual chars [21]. The char residue value of pristine cotton was 12.5%.…”

The cotton textiles with superhydrophobic and flame-retardant properties used in this study were manufactured by combining nano APP@SiO2 with silicone oil. To generate nano APP@SiO2 particles, the APP is coated with nano SiO2. The nano APP@SiO2 improves the flame retardancy of cotton textiles while altering the surface roughness of cotton fabrics, making them superhydrophobic after being treated with silicone oil. Cotton fabrics’ surface topography, chemical components, crystalline structure, thermal stability, flame-retardant, and superhydrophobic properties were investigated. The modified cotton fabric demonstrated not only exceptional superhydrophobicity with a WCA of 151.28°, but also good flame-retardant property. This multifunctional cotton fabric offers a wide range of commercial applications.

“…5 It can form the char layer as a barrier between flammable or combustible gas and heat or flame to protect the substrate against fire or heat. It was reported that intumescent coating could enhance the flame retardancy and anti-dripping properties of fabrics such as nylon, 6 cotton 7,8 and PET. 9 The intumescent can be the insulating layer between the substrate and flame or heat and it does not interfere with the properties of material, such as the mechanical properties.…”

“…It can generate a thin film on the substrate by sequential and repeating adsorptions of cationic and anionic polyelectrolyte solution to build up the construction of BLs. 8 The thickness of the layer was controlled by the multilayer condition and the number of BLs. The LBL assembly could be applied on the substrate by many techniques, such as the deposition and spraying techniques.…”

Intumescent coatings consisting of branched-polyethyleneimine (BPEI) and ammonium polyphosphate (APP) solution were successfully applied on polyester fabrics by the layer-by-layer assembly technique to enhance the flame retardant and anti-dripping properties of polyester fabrics. The surface morphology of fabrics revealed that the coatings thoroughly covered the fabrics. The assessment of the vertical burning test of thin material (UL-94 rating VTM 0) indicated that the flame retardancy of coated polyester fabrics was improved significantly as compared with the uncoated fabric. The self-extinguishing ability and anti-dripping behaviors of coated polyester fabrics were also enhanced markedly. The improvement of flame retardancy depends on the number of coating layers and the amount of APP. However, after washing, the flame retardancy decreases to some extent. The morphology of char exhibits the typical structure of intumescent char on coated fabrics. The assessment of mechanical properties revealed that the intumescent coating via layer-by-layer assembly did not deteriorate the strength of the fabric. The increasing number of coated layers leads to the slight increase of the breaking force of the fabric; however, the increasing number of layers and the increasing amount of prepared APP lead to increased rigidity of the fabrics.
