Textiles et tissus synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The present research manages the utilisation of post-treatment coating solutions of aminopropyl/vinyl/silsesquioxane (APSV) for ink-jet printing of polyester with CMYK (cyan, magenta, yellow and key [black]) pigmented water-based ink-jet inks. The proposed protocols could effectively fix the pigment colours on polyester at a low relieving temperature under the thermal initiation or ultraviolet (UV)-radiation of vinyl terminated groups in APSV compared to the commercial textile binders. The colorimetric data and fixation, antistatic properties, roughness and durability of the ink-jet-printed samples were studied. The outcomes demonstrated that APSV successfully fixed the pigment-based ink-jet inks on polyester fabric, and could achieve significantly higher colour performance and degree of fixation than the commercial textile binders. The APSV-post-treated examples had durable antistatic properties and soft handle. The durability tests indicated that the ink-jet-printed polyester fabrics post-treated with APSV retained a higher degree of fixation and antistatic properties after 10 launderings. In general, the outcomes revealed that APSV can be successfully utilised as a pigment binding agent, eliminate all determinant drawbacks in works of literature for treatment of fabrics in ink-jet printing application, such as the fabric handles and the many approached methods. Moreover, it showed a good durable antistatic finish for the post-treatment of ink-jet-printed polyester fabrics. Note de contenu : - EXPERIMENTAL : Materials

ThermochromieIndex. décimale : 677.4 Textiles artificiels Résumé : High-performance fibers that have been exposed to high temperatures usually lose their mechanical properties undetected and, in the worst case, can tear precisely when lives depend on them. These include, for example, safety ropes used by fire brigades or suspension ropes for heavy loads on construction sites. Empa researchers have now developed a coating that changes color when exposed to high temperatures through friction or fire. Note de contenu : Wafer-thin layers with great effect

Textiles et tissus synthétiquesIndex. décimale : 668.4 Plastiques, vinyles Résumé : This study focuses on fabrication of aerogel-coated macroporous polyester fabrics for the purposes of filtration of nanometric airborne particles and potential application in facemasks. Syndiotactic polystyrene (sPS) and polyimide (PI) gels that provide respectively majority macropores (diameter > 50 nm) and mesopores (diameter 2 to 50 nm) are coated onto woven polyester fabrics via a dip coating process. The resultant materials are supercritically dried to obtain aerogelcoated fabrics. The results show that sPS is more suitable for the dip coating process. However, evaporation of the solvent during handling of gel-coated fabrics leads to closure of the surface pores that are later recovered via solvent annealing. The resultant aerogel-coated fabrics offer high air permeability (∼10–10 m2) and high filtration efficiency (> 99.95%) of airborne sodium chloride test particles of size 25 to 150 nm.

Textiles et tissus synthétiquesIndex. 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.

GraphèneLe graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié). Record en conduction thermique jusqu'à 5300 W.m-1.K-1. C'est aussi un matériaux conducteur.

Traitement thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : This work reports the preparation and application of microwave thermally expanded graphene (G)/polyaniline (PANI) conductive paste. The results from XRD revealed that the polyaniline did not change its crystal structure after being combined with microwave thermally expanded graphene. FTIR and Raman spectra revealed that there was a strong π–π interaction between polyaniline and microwave thermally expanded graphene. The resultant conductive pastes possess obvious shear-thinning phenomenon, which are suitable for screen printing to produce conductive circuits. The printed polyester fabric showed significant conductivity which can be tuned by changing the printing time and line length. This study paves the way to large-scale fabrication of flexible conductive circuits for various applications. Note de contenu : - Experimental : Materials
