“…Accordingly, as can be seen in Table 2, the tilting angle in the technical face decreased after alkaline hydrolysis-fluorochemical treatment in comparison with the samples treated by the fluorocarbon alone with statistically significant difference. Thus, in such a way superhydrophobic textiles were obtained by creation double scale topography containing fabric structure and created cavities, mimicking the lotus leaf effect, which is compatible with the previous reports [16]. In this section double cross tuck as a best specimen (with lowest tilting angle) was selected.…”

“…In order to study the samples hydrophobicity, tilting angle [16,17], contact angle hysteresis and the 3M water repellency tests [18] were examined. Tilting angle of droplet on the fabric was measured [16] on the technical face and back (wale and course directions) by a home-built instrument as shown in Figure. 2.…”

“…According to the study of Mazrouei and Khoddami [16], an alkaline hydrolysis process is able to create proper surface roughness with an enhancement in the textiles hydrophobicity after fluorocarbon treatment. By the alkaline treatment, the nucleophilic attack of NaOH on PET chains leads to chain scissions at the ester linkages and in the presence of TiO2, particles makes some pits and cavities on the surface [24].…”

A superhydrophobic surface with self-cleaning properties can be fabricated with a combination of both low surface energy and the proper surface roughness. In this paper, the possible effects of structural parameters of weft knitted fabrics were applied to produce surface roughness while a fluorocarbon compound was coated on the surface in order to generate low surface energy. In addition, to create dual surface roughness on the polyester fibers, chemical etching with alkaline hydrolysis and application of nanoparticles were investigated. The water repellency of the treated samples was evaluated by 3M, tilting angle and contact angle hysteresis.Comparison of a smooth polyester film and the knitted fabrics showed that various knitted structures and stitch densityhad a great effect on superhydrophobicity. Polyester alkaline hydrolysis efficiently roughened the surface and after the fluorocarbon coating, remarkable improvement in repellent properties was observed. Thus, there was no necessity to use nanoparticles.

Multiscale structures of biotic materials exhibiting natural integration provide a model for the development of functional surfaces with special wettability. Inspired by nature, for example, by the lotus leaf and butterfly wings that show excellent superhydrophobicity, scientists have recently fabricated a variety of biomimetic superhydrophobic membranes through various smart and easy routes. After a brief description of natural superhydrophobic surfaces and the structural and functional biomimetic surfaces, we present the design and fabrication methods of these bio‐inspired superhydrophobic fibrous membranes. The main focus is the overview of the polymeric materials used to fabricate the superhydrophobic fibrous membranes at nano‐ or microscales and the chemical modifications that led to superhydrophobicity of as‐prepared polymeric and inorganic fibrous membranes. Later, we describe the induced superhydrophobicity in common textile fibrous surfaces. In addition, we highlight some potential applications associated with these remarkable biomimetic surfaces.

In this research, polyester fabric was modified through in situ synthesis of Cu/Cu 2 O nanoparticles (NPs) in one single step processing using diethanolamine. This introduced amide and hydroxyl active groups on the polyester surface, adjusted pH, aminolyzed, and improved the surface activity of polyester. Copper sulfate was used as precursor, sodium hypophosphite as a reducing agent and polyvinylpyrrolidone as a stabilizer in a chemical reduction route at boil as a facile and cost-effective approach. The central composite design was also utilized to optimize the processing conditions and study the effect of each variables on the weight gain, color change, and wettability of the treated fabrics. FESEM and mapping, EDX, XRD, and FTIR analysis confirmed effective assembling of Cu/Cu 2 O NPs on the amidohydroxylated polyester surface. The optimum treated fabric showed excellent antibacterial properties on both Staphylococcus aureus and Escherichia coli. In addition, a very good photocatalytic activity towards degradation of methylene blue solution obtained after 24 h sunlight irradiation. Further, the hydrophilicity, mechanical properties and stability of the treated fabrics in concentrated sodium hydroxide improved through formation of amidohydroxyl active groups, amidoester crosslinking and nanocross-linking within polymeric chains through in situ synthesis of Cu/Cu 2 O.
