[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 70, N° 4 (12/2020) . - p. 141-142 Titre : Active sportswear fabric with cellulosic fiber Type de document : texte imprimé Auteurs : Abir Chakrabarty, Auteur ; Somes Bhaumik, Auteur ; Ketan Patel, Auteur ; Rituraj Nagpure, Auteur ; Akash Bansode, Auteur Année de publication : 2020 Article en page(s) : p. 141-142 Langues : Anglais (eng) Catégories : Antimicrobiens Confort Fibres cellulosiques Hydrophilie Hydrophobie Jersey (tissu) Le jersey est une maille fine tricotée utilisée principalement par l'industrie de l'habillement. Confectionné à l'origine en laine, le jersey est maintenant également réalisé en coton ou en fibres synthétiques. Ce tricot tire son nom de l'île de Jersey, où le mot désigne depuis la fin du XVIe siècle les produits textiles qui en sont originaires. Ce tricot est aujourd'hui communément utilisé comme base pour les T-shirts. Il peut avoir différents grammages qui sont un indicateur de sa qualité. Caractéristiques : Le jersey est une étoffe qui a une élasticité naturelle grâce aux mailles tricotées (point jersey) même si le fil utilisé pour le tricotage a une élasticité nulle. Contrairement aux tissus en chaine et trame, les tissus en jersey ne s'effilochent pas sur les bords coupés à cru. Les tissus en jersey ont une tendance à roulotter sur les bords coupés à cru. C'est pour cette raison qu'ils sont ourlés.

Infusing cellulosic fiber into sportswear helps in further reduction of carbon footprint in the environment and up-scales the sustainability. Various comparative knit fabrics and yarns which impart value addition in sportswear were developed. The present study examines union blend of hydrophobic/hydrophilic 60/40 with pleating as well as single jersey knit fabric for better moisture management and comfort which is a primary requisite in sportswear applications.

Advances in emerging hydrogel fouling-release coatings for marine applications / Michael Kio in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 21, N° 3 (05/2024)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 21, N° 3 (05/2024) . - p. 827-856 Titre : Advances in emerging hydrogel fouling-release coatings for marine applications Type de document : texte imprimé Auteurs : Michael Kio, Auteur ; Jeffery Klauda, Auteur Année de publication : 2024 Article en page(s) : p. 827-856 Note générale : Bibliogr.

Current commercial traditional antifouling coatings suffer from reduced energy efficiency and short lifespan and contain heavy metals that are toxic to marine organisms and humans. The banning of these coatings is due to environmental concerns, and nonbiocidal alternatives such as polymer-based coatings are being sought after. This review demonstrates emerging promises of hydrogel fouling-release coatings (FRCs) in the marine environment that may be effective against a prevalent amount of biofouling agents. The review also highlights the importance of polymer backbone materials with surface wettability characteristics possessing hydrophobic, hydrophilic, and zwitterionic properties and further discusses emerging antifouling techniques, synthesis of hydrogel, swelling behavior of hydrogel, laboratory assays of hydrogel coating, marine field test, and outlook of hydrogel fouling-release (FRCs) coatings.

Antifouling improvement of a polyacrylonitrile membrane blended with an amphiphilic copolymer in INTERNATIONAL POLYMER PROCESSING, Vol. 37, N° 1 (2022)  

[article]  inINTERNATIONAL POLYMER PROCESSING > Vol. 37, N° 1 (2022) . - p. 93-105 Titre : Antifouling improvement of a polyacrylonitrile membrane blended with an amphiphilic copolymer Type de document : texte imprimé Année de publication : 2022 Article en page(s) : p. 93-105 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Adhésion Caractérisation Copolymère acrylonitrile-co-polyhydroxyéthyl méthacrylate Copolymères Hydrophilie Matériaux -- Propriétés antisalissures Membranes (technologie) Perméation Polyacrylonitrile Polymères amphiphiles Taille des pores Index. décimale : 668.4 Plastiques, vinyles Résumé : The amphiphilic copolymer polyacrylonitrile-co-poly(hydroxyethyl methacrylate) (PAN-co-PHEMA) was readily blended with polyacrylonitrile (PAN) to fabricate a flat-sheet blending membrane through non-solvent induced phase separation (NIPS). In the membrane-forming process, the hydrophilic PHEMA chains are uniformly distributed on the surface, as revealed by the energy-dispersive X-ray tests. The sponge-like sub-layer embedded with droplet-shaped structures is formed at the cross-sections of membranes, because of the high viscosity of the casting solution. With the increase of copolymer concentration, the mean pore size of the blending membranes increases from 26.9 to 99.8 nm, leading to the increase of membrane flux from 93.6 to 205.4 l/(m2h). The incorporation of PAN-co-PHEMA copolymer endows the blending membrane with a rough surface microstructure and enhanced hydrophilicity. The rejection ratio of membranes for emulsified pump oil reaches 99.9%, indicating a prominent separation performance. In the cycle permeation experiments, the flux recovery ratio of the blending membranes is as high as 99.6%, which is much higher than those of PAN membrane. The irreversible fouling of blending membranes induced by oil adsorption is alleviated, and converted into reversible fouling, owing to the reduction of the adhesion force between foulant and membrane surface. These results suggest that the anti-fouling property of PAN membranes has been dramatically strengthened via the addition of PAN-co-PHEMA copolymer.

Bio-inspired fabrication of superhydrophilic and underwater superoleophobic alumina membranes for highly efficient oil/water separation / Wenjin Zhou in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 18, N° 2 (03/2021)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 18, N° 2 (03/2021) . - p. 361-372 Titre : Bio-inspired fabrication of superhydrophilic and underwater superoleophobic alumina membranes for highly efficient oil/water separation Type de document : texte imprimé Auteurs : Wenjin Zhou, Auteur ; Mingyang Zhou, Auteur ; Huapeng Zhang, Auteur ; Hongyan Tang, Auteur Année de publication : 2021 Article en page(s) : p. 361-372 Note générale : Bibliogr.

Dopamine deposited on the surface of alumina membranes through immersion over time, and then crosslinking reaction occurred with polyethyleneimine (PEI), which was confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. It induced the modified layer coated on the membrane surface. Values of water contact angle of the modified alumina membranes were ~ 0° in air. Values of underwater oil contact angle reached 155°, which indicated it was superhydrophilic and underwater superoleophobic. More particles engendered with the increase in the reaction time with PEI, which induced the decrease in the pore sizes and permeation flux. All values of oil rejection were higher than 98.5%. No obvious deterioration of permeation flux could be found. The rejection hardly suffered a sharp decline over 800 min. It indicates that the modified layer can firmly stick to the alumina membranes. Therefore, the as-prepared alumina membrane is promising for practical oil/water separation.
