Enduction textile Hydrophobie Séparation huile/eau Stéarate de nickel Textiles et tissus auto-nettoyants Index. décimale : 667.9 Revêtements et enduits Résumé : A fluorine-free superhydrophobic cotton fabric based on nickel stearate with multifunctional properties has been fabricated by a two step simple solution process. The cotton fabric (aNS-CF) exhibits static water contact angle, ~ 160°, and water shedding angle, < 10°, due to in-situ formation of hierarchical (micro and nano) broccoli-like structures of nickel stearate. The superhydrophobic cotton fabric, having superoleophilic property, has been used for separation of a series of light/heavy oil–water mixtures, and ~ 99% separation efficiency has been achieved after 10 cycles of separation process and it has been found to be slightly reduced to ~ 98% after 50 cycles. Antifouling and self-cleaning performance of the fabric has been evaluated effectively using solid and liquid contaminants as well as some common food liquids. The coating exhibits significant mechanical and chemical robustness and laundering durability in harsh conditions. The coated fabric possesses antibacterial (gram-negative E. coli and gram-positive S. aureus) and antifungal (C. albicans) properties leading to ~ 99.99% reduction in microbial growth, which has been remarkably sustained after 50 cycles of washing, abrasion and separation of oil–water mixtures. The stable multifunctional properties of the fabric exhibits a great potential towards a huge domain of practical implementations in smart textiles.

TiO2-consisting coating compounds were prepared at four different processing temperatures (20, 40, 60, and 80°C) in order to examine the influence of process temperature on average particle size. Among the prepared solutions, the one prepared at 80°C process temperature was selected for the dip coating application of the 100% cotton fabric, which formed a transparent nanosized TiO2 film on the fibrous structure of fabric. Dip coating trials were done at five coating temperatures of 20, 40, 60, 80, and 100°C. TiO2-coated and uncoated fabric samples were then tested to evaluate their self-cleaning and antibacterial activities. A self-cleaning activity test was conducted using uncoated and TiO2-coated fabric samples which were stained with hot tea solution via dipping method. Stained fabric samples were illuminated under a solar simulator for the color changes to measure photocatalytic degradation of stain colors. Antibacterial performance of TiO2-coated and uncoated fabric samples was determined against pure cultures of Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 29213.

Microwave-assisted preparation of pyrite and its sensitisation of titanium dioxide in self-cleaning aramid fabrics / Chenghui Zheng in COLORATION TECHNOLOGY, Vol. 134, N° 4 (08/2018)

Résistance au rayonnement ultraviolet Textiles et tissus auto-nettoyants Textiles et tissus synthétiques Index. décimale : 667.3 Teinture et impression des tissus Résumé : Titanium dioxide (TiO2) dispersions were obtained by neutralising anatase nano‐titanium dioxide sols prepared by hydrolysing tetrabutyl titanate in acidic aqueous media. Pyrite was initially prepared via the microwave‐assisted method with a mixed solvent of ethylene glycol and small amounts of water, and was then used in sensitising micron‐sized titanium dioxide particles to obtain aramid fabrics with self‐cleaning properties. X‐ray diffraction demonstrated the crystalline structure of pyrite, and ultraviolet‐visible (UV‐vis) spectrum and energy‐dispersive X‐ray spectroscopy characterised the band gaps, surface status on fabrics and the distribution of the pyrite compound's titanium dioxide particles. The contact angle, UV protection factor (UPF) and photocatalytic degradation of methylene blue (MB) were used to evaluate the performance of treated aramid fabrics. Results show that pyrite‐sensitised titanium dioxide compounds obtained at pH 5 have smaller band gap energies and relatively poor wetting abilities, higher UPF values, and perform well in the photocatalytic degradation of MB. The pseudo‐first kinetic model was used to analyse elaborate sections of the curve for the degradation of MB.

Preparing self-cleaning superhydrophobic fiber@POSS garment fabric by UV-curing-induced high surface roughness / Ping Guo in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 20, N° 1 (01/2023)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 20, N° 1 (01/2023) . - p. 249-260 Titre : Preparing self-cleaning superhydrophobic fiber@POSS garment fabric by UV-curing-induced high surface roughness Type de document : texte imprimé Auteurs : Ping Guo, Auteur ; Xiaomiao Zhao, Auteur Année de publication : 2023 Article en page(s) : p. 249-260 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Caractérisation Hydrophobie Matériaux -- Propriétés antisalissures Photoréticulation Rayonnement ultraviolet Silsesquioxanes oligomères polyhèdres Textiles et tissus auto-nettoyants Index. décimale : 667.9 Revêtements et enduits Résumé : Self-cleaning outdoor garment fabrics are desired. However, traditional fiber cloths made from cellulose show a poor antifouling property owing to surface hydrophilicity. In this work, fiber@poly(vinyl silsesquioxane) (POSS) fabric with self-cleaning trait and superhydrophobicity was fabricated via surface ultraviolet (UV) curing (UV-induced click reaction). Its surface micromorphology and elemental distribution were studied. Compared with pristine fiber cloth, POSS-modified fiber cloth can exhibit the superhydrophobic, nonstick, and antifouling traits. Superhydrophobicity of the modified cloth is ascribed to synergy between high surface roughness (cage-like POSS; crosslinked (3-mercaptopropyl)trimethoxysilane; woven fibers) and low-surface energy (Si/-CH2-). Self-cleaning property of modified cloth results from superhydrophobicity. After water/surface contact for 60 min, the static water contact angle of modified cloth surface can reach 158.7 ± 1.6°. Superhydrophobic durability of modified cloth reaches 120 h under acid/base/UV irradiation. After 100 abrasion cycles or 1 laundering cycle, the superhydrophobicity is maintained. The novelty of this work is a rapid UV-curing fabrication of self-cleaning POSS-modified fiber cloth. This work might open up a way for preparing advanced self-cleaning garment fabrics.
