Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This study investigates the structures produced by blending ligno-cellulosic (ramie fibre, Boehmeria nivea L.) and protein fibres (mulberry silk, Bombyx Mori) with dissimilar mechanical properties. Ramie fibre, used for blending, is a ligno-cellulosic fibre with very high tenacity but low elongation. On the other hand, silk (mulberry) fibre has lower tenacity with better elongation. Blended fibrous structures have shown satisfactory tensile strength and elongation, while other physical properties, such as coefficient of friction, brightness and flexural rigidity, have also been improved. Technical findings revealed that the coefficient of friction reduced from 0.79 to 0.48 and specific work of rupture improved from 2.3 to 3.43 mJ/tex after incorporation of silk in the ligno-cellulosic fibre strand. Blended yarn cross-sectional images showed that finer silk fibres came to the surface, whereas the comparatively coarser cellulose-based ramie fibre migrated to the core. Atomic force microscopy of the blend structure was examined to assess the roughness and uniformity of the surface. Fourier Transform–infrared spectroscopy analysis verified the presence of amide groups (associated with silk fibre) and glucose ring groups (associated with the cellulose of Ramie fibre) in the same graph. In addition, innovative techniques of simultaneous coloration of the developed blends are also proposed scientifically.

TachesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Parchment is a very beautiful material; very strong but also very fragile in an unsuitable storage environment. Actually, as regards to the dust and grime accumulated in normal museums and library storage, the cleaning of parchment is a fairly simple task. Stains on parchment which are due to damp, dust, mould, ink, colour migration and etc. are a problem for conservators, but with care and patience may usually be treated successfully. This study uses artificial stains (similar to the natural stains, which can be found on historical parchment) on new and aged parchment (prepared by the author) to evaluate the materials and methods used in cleaning processes. The advantages and disadvantages of bleaching materials used after a cleaning process were also recorded.
Colour was measured by spectrophotometer and the surface morphology examined by the use of a scanning electron microscope. Mechanical properties were determined and Energy Dispersive X-Ray Analysis was also used to evaluate the cleaning materials and methods.The results have shown that mechanical cleaning methods have certain advantages for the object since nothing is added during the cleaning. In chemical cleaning, water should not be used alone but must be used mixed with an organic solvent. Mechanical cleaning methods are safer than chemical cleaning methods.Note de contenu : - MATERIALS AND METHODS : New parchment - Artificial stains applied on new parchment - Stain application details - Accelerated ageing - Cleaning materials and methods

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.
