The aim of this research is to produce a substrate that can be used for the development of protective gowns. For this purpose, a cotton-polyester blended plain weave fabric was treated with a coating paste comprising fluorocarbon and acrylic resins. The coating process parameters, which are fluorocarbon resin quantity (%), acrylic paste quantity (g m−2), and reticulation time (min), were varied by using a Box–Behnken experimental design. Textile fabric characteristics in terms of thickness (mm), coating add-on (%), air permeability (L m−2 s−1), surface hydrophobicity (mg cm), and flexural rigidity (mg cm−1) were then analyzed and discussed.

“…Electrospinning technology is a low-cost and high-efficiency method for preparing nanofiber membranes. − More and more polymers are electrospun into nanofibers, such as polyacrylonitrile (PAN), polyurethane (PU), polyvinylpyrrolidone (PVP), poly(vinylidene fluoride) (PVDF), poly(vinyl alcohol) (PVA), etc. − The obtained polymer nanofiber membrane has the characteristics of nanoscale fiber diameter, high porosity, small pore size, and adjustable pore structure, − so it is widely used as waterproof and breathable medical or filtration materials. − For these applications, outstanding hydrophobicity is often a precondition or very necessary. At present, the normal way of preparing hydrophobic materials is to reduce the surface energy or increase the surface roughness of materials. − Some studies have shown that the introduction of inorganic nanoparticles on the material surface can not only reduce the surface energy of the material but also improve the surface roughness of the material …”

In this paper, hydrophobic PAN/SiO 2 −PU composite nanofiber membranes were prepared by coaxial electrospinning combined with a hydrothermal method. The effects of the feeding rate ratio of the shell (PAN/SiO 2 ) solution and the core (PU) solution, the content of SiO 2 in the shell solution, and the hydrothermal time on the composite nanofiber membrane were analyzed. The results showed that when the feeding rate ratio of the shell−core solution was 5:1 and the SiO 2 content in the shell solution was 60 mg•mL −1 , the PAN/SiO 2 −PU nanofiber presented a uniform diameter and an obvious shell−core structure, and the Si element was uniformly distributed on the fiber surface. After hydrothermal treatment, the surface water contact angle of the PAN/SiO 2 −PU composite nanofiber membrane reached 152°, and the water vapor transmission rate was 8.48 kg•m 2 •d −1 . In addition, the average solar reflectance of the composite nanofiber membrane was as high as 60.29%, and the temperature difference between the PAN/SiO 2 −PU and PAN−PU composite nanofiber membranes was 4.5 °C, indicating an obvious radiative cooling effect.

“…Many studies have been carried out to improve the waterproofness [1] and breathability of fabrics [2][3][4]. These textile materials do not only have the ability to protect the wearer from rain but also to provide him with a comfortable feel by transferring moisture out of the garment [2,3,[5][6][7][8][9][10]. For waterproof breathable apparels, resistance to wind is also evaluated [2,3].…”

“…Few studies analyzed the water repellency, waterproofness, windproofness, and water vapor permeability of textile materials such as PET, nylon, cotton, and wool [40]. In a previous study, Ghezal et al [9,41] developed a coated textile by applying a mixture of a fluorocarbon resin and an acrylic paste to a double-sided knitted fabric. The novelty was introducing a new coating made of industrialized chemical products that does not require water use.…”

The demand for waterproof breathable fabrics is increasing globally and so are efforts to develop such garments. In this paper, the development of a waterproof breathable textile by coating a double face knitted fabric is described. The applied polymeric coating is a mixture of an acrylic paste and a fluorocarbon resin. The aim of this study was the investigation of the breathability and waterproofness of the coated samples. The coating was made of industrialized chemical products and did not require water use. The screen coating process wastewater was also reduced. Three parameters related to the coating process were analyzed and optimized. These parameters were the fluorocarbon resin quantity (%), acrylic paste quantity (g·m−2), and reticulation time (min). The analyzed responses were the air permeability, windproofness, water vapor permeability, and resistance to water penetration. The optimized values of air permeability and water vapor permeability were equal to 154.81 L·m−2·s−1 and 83.852%, respectively. These values were judged acceptable when compared with commercialized products. The windproofness and the resistance to water penetration were equal to 161.81 L·m−2·s−1 and 78.51 Schmerber, respectively. Thus, both responses still need to be improved in order to obtain waterproofness properties. Based on the obtained results, the coated fabric can be used as a laminate outer layer for producing waterproof breathable fabrics.
