The numerical simulation helps to better understand the coextrusion process for polyester films and the emergence of clear edges. In addition, it can be determined how different viscosities influence the film structure. Note de contenu : - Polyester film production

Textiles et tissus synthétiquesIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Synthetic fabrics of polyesters improve in comparison to cotton the durability of apparels and household linen but lead due to their hydrophobic characteristics to problems of removal greasy soil which have a high affinity for hydrophobic synthetic fabrics improving their adhering to the hydrophobic fiber. The hydrophilic cotton fiber absorbs, by contrast, water quite well in the washing process, which makes the soil and stains easier to remove.
By physical absorbing of Repel-O-Tex soil release soil polymers (SRP) interactions between synthetic fabric and greasy soil are reduced and their surface hydrophilicity is enhanced making stain removal easier. Already at the first wash a strong adhesion of soil particles on the fibers is prevented and in the second the soil removal becomes much easier. In the following washing cycles the washing effect will be enhanced by obtaining the whiteness of the fibers without a build-up effect on the surface.Note de contenu : - Repel-O-Tex soil release polymers in the washing process

Titre : Statistical study of hydrolytic stability in amine-neutralized waterborne polyester resins as a function of monomer composition Type de document : texte imprimé Auteurs : Travis E. Jones, Auteur ; Julia M. McCarthy, Auteur Année de publication : 1995 Article en page(s) : p. 57-65 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Amines Une amine est un composé organique dérivé de l'ammoniac dont certains hydrogènes ont été remplacés par un groupement carboné. Si l'un des carbones liés à l'atome d'azote fait partie d'un groupement carbonyle, la molécule appartient à la famille des amides. Découvertes en 1849, par Wurtz les amines furent initialement appelées alcaloïdes artificiels.
On parle d'amine primaire, secondaire ou tertiaire selon que l'on a un, deux ou trois hydrogènes substitués.
Par exemple, la triméthylamine est une amine tertiaire, de formule N(CH3)3.
Typiquement, les amines sont obtenues par alkylation d'amines de rang inférieur. En alkylant l'ammoniac, on obtient des amines primaires, qui peuvent être alkylées en amines secondaires puis amines tertiaires. L'alkylation de ces dernières permet d'obtenir des sels d'ammonium quaternaire.
D'autre méthodes existent : 1. Les amines primaires peuvent être obtenues par réduction d'un groupement azoture, 2. Les amines peuvent aussi être obtenues par la réduction d'un amide, à l'aide d'un hydrure, 3. L'amination réductrice permet l'obtention d'amines substituées à partir de composés carbonylés (aldéhydes ou cétones), 4. Les amines primaires peuvent être obtenues par la réaction de Gabriel.

StatistiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Reversibility of the esterification reaction has limited the use of polyester resins in waterborne coating systems. As with other polyester resin properties, the rate of hydrolysis can be modified by choice of monomer. The objective of this study is to demonstrate changes in hydrolytic stability in waterbone polyesters as a function of change in glycol and diacid composition. In the glycol section of the study, BEPD and HPHP were compared. For the diacid section, adipic acid, isophthalic acid, and 1,4-CHDA were examined. Aqueous dispersions were subjected to storage at both ambient and elevated temperature. Response factors measured over time included molecular weight, pH, appearance, and change in properties of coatings made from the aged dispersions. Results are discussed with reference to accepted hydrolysis hydrolysis rate theories. Results show that inductively stabilized, hydrophobic monomers such as 1,4-CHDA and BEPD produce the most stable waterborne polyesters of the glycols and diacids studied.

CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : There is a noticeable growing interest in the use of natural dyes in contemporary textile dyeing, motivated by the requirements imposed, in favour of environmental prosperity. The use of natural dyes reduces significantly both the energy requirements and the environmental impact of the process. In the present work natural and synthetic fibres were dyed with the dyestuff isolated from Crocus sativus L., after aqueous extraction of the dried stigmas of the plant. Additionally, part of the powder was purified by using ultrafiltration technology. The saffron extract and the ultrafiltrated saffron retentate were used to dye cotton, wool, nylon and polyester, in various depths of shade and temperatures. Both saffron and ultrafiltrated saffron successfully dyed not only the natural substrates, but also the synthetic ones, while higher dyeing temperatures produced level dyeing with all substrates used. Ultrafiltrated saffron powder produced brighter and much stronger dyeing to the original saffron powder, due to the elimination of extraction by-products. Isothermal adsorptions for both colourants were performed on all substrates in order to investigate their adsorption mechanism. It was found that saffron and ultrafiltrated saffron follow a Freundlich-type adsorption isotherm on cotton, wool and nylon which is a typical mechanism for a planar-directed dye of big molecular weight. Nernst-type adsorption was found to occur on polyester which again is typical for the adsorption of disperse dyes on polyester. Thus, saffron can be claimed as a universal dye, able to successfully dye natural and synthetic substrates.
