This condensate reduces the driver's visibility, and the film also promotes dust adhesion, which further worsens the problem. Leather upholstery and fittings are important components for adding value in the automotive sector, and the fogging phenomenon can be reduced by careful attention in three areas.

TempératureIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The work in this paper describes the modification of collagen hydrolysate with 1-ethyl-3- (3-dimethyl aminopropyl)-carbodiimide (EDAC). The effects of factors that may affect the cross-linking reactions in the process of modification such as EDAC level, reaction temperature, reaction time, and pH were studied. The optimal modification conditions were obtained to give modified products with the best emulsification and emulsion stability. Changes in molecular weight, emulsification capacity, emulsification stability, water absorption and oil absorption of the collagen hydrolysate before and after modification were studied and compared.

Revêtements antigelIndex. décimale : 667.9 Revêtements et enduits Résumé : A common phenomenon concerning cold surfaces which are subjected to a warmer, more humid atmosphere is condensation in the form of water droplets (fogging) or even ice crystals (icing). Thus, a previously transparent object becomes opaque because light is scattered by the droplets or crystals. This may impair the usability of that object. We developed an anti-fogging/icing coating which overcomes the problem of fogging and icing by being able to absorb the condensing water and preventing it from crystallizing. The coating consists of poly(1-vinyl-2-pyrrolidone) (PVP) crosslinked by UV light using hydrogen peroxide (H2O2). Benzophenone (BP) is used to attach PVP to the surface of the polystyrene (PS) substrate. At temperatures as low as -60°C, the PVP coating can absorb up to 70 wt% of water and still inhibit its crystallization. However, at surface temperatures of around -18°C, opacity is only observable at 150 wt% of absorbed water and higher. An increasing coating thickness as well as a decreasing crosslink density improves the anti-fogging/icing effect because the coating can absorb more water. The abrasion resistance of the coating is impaired by a decreasing crosslink density. Note de contenu : - MATERIALS AND METHODS : Coatings process - Characterization of the coatings

Modal (textile)Le modal est une fibre textile artificielle, obtenue par le filage de fibres de cellulose de bois (souvent du hêtre). Le modal a la particularité d'être environ 50 % plus hygroscopique que le coton, à volume égal. Le modal est un type de viscose (comme la viscose, c'est une fibre reconstituée à partir de cellulose). Le modal peut être utilisé seul, ou associé avec d'autres fibres (souvent du coton et/ou de l'élasthanne).
Les textiles faits à partir de, ou contenant du modal, ont la particularité de rester souples et doux même au bout de plusieurs lavages. Les dépôts solides dus aux eaux calcaires ne peuvent pas s'y accrocher. De plus, ils résistent au rétrécissement.
L'aspect du modal peut être brillant, mat ou coloré dans la masse. On retrouve ainsi le modal dans des articles tels que des serviettes, peignoirs de bain, sous-vêtements, ou des draps. Lenzing Modal est une marque déposée de l'entreprise Lenzing AG (en), entreprise autrichienne spécialisée dans les fibres textiles et plus particulièrement dans les fibres de celluloses non-tissées.
ViscoseIndex. décimale : 677.4 Textiles artificiels Résumé : The moisture absorption and liberation properties of hollow viscose fiber were tested and analyzed with regression analysis to establish the regression equation. In addition, the same properties of the other 3 regenerated cellulose fibers, including conventional viscose, modal and lyocell were tested to observe the differences existing among these 4 fibers. The results show that the moisture content of absorption and liberation of hollow viscose fiber are 11.74% and 13.78%; conventional viscose fiber of 13.34% and 15.64%; modal of 11.87% and 13.99 %; lyocell of 10.97% and 13.12 %, respectively, All the moisture absorption and liberation curves of the 4 fibers show that in the initial stage, the rates of the moisture absorption and liberation are fastest and then slow down gradually with the increase of the time, Hollow viscose fibers need less time to reach equilibrium than any others.

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

Résistance au lavageIndex. décimale : 677.47 Non cellulosiques : Nylon, acryliques, polyesters, vinyles Résumé : Polyamide (PA) fiber, and blends with it, are broadly used in athleisure, stockings, inner wear and sportswear. PA, having numerous advantages, has the drawback of generating static charges due to its less hydrophilic nature. This leads to fabric clinging to the wearer. Also, the sweat generated during activity will not be transported out, making it uncomfortable to the wearer. For this reason, there has been great demand for the hydrophilic finishing technology that could be applied to PA fiber by exhaust or dipping method. In this study, hydrophilic polyester (PET) resin, was applied on PA knitted fabric by dipping method. The treated fabric was tested for water absorption, wicking and moisture management property. Fabrics treated with Estofeel (Conc), a moisture absorber by Sarex Chemicals, showed higher absorbency, wicking and better moisture management property as compared to unfinished fabrics. These treated fabrics can thus have a great application in sportswear, athleisure wear and provide better comfort to the wearer.
