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).

Accordingly, some bio-mordants including tannic acid, pine cone, lemon peel, and sodium alginate, as well as some metal mordants such as iron(II) sulphate, copper sulphate, zinc sulphate, and aluminium potassium sulphate were investigated based on three conventional mordanting procedures (pre-, meta- and after-mordanting). The method appropriate for H. sabdariffa dyeing on the cotton fabric, according to the colour fastness factor, was found to be the after-mordanting method. The bio-mordants used in this study, the same as metal salts, increased the colour fastness on the dyed cotton fabrics and produced excellent light fastness (rating of 5 to 6), wash fastness (rating of 4 to 5), and dry/wet rub fastness (rating of 4 to 5). The higher antibacterial activities (> 90% bacterial reduction) against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa were observed when tannic acid, pine cone, and lemon peel were applied to the dyed cotton fabric. The use of bio-mordants in the natural dyeing of the cotton fabric could be, therefore, recommended due to the biocompatibility and non-toxicity of natural mordants, along with excellent colour fastness and appropriate antibacterial properties.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Because of the environmental burden of synthetic dyes, there has been a revival in practising natural dyeing globally. Natural dyeing uses metallic mordants for improving the dye's fastness properties. However, metallic mordants are also toxic. Herein, both the dyes and mordants were extracted from plant waste using water as a green solvent. The extracted dyes were then applied to the cotton fabric using a natural mordant. The dyed fabric samples were characterised for colour yield, fastness properties, ultraviolet protection and antibacterial activity. For the intended purpose, the wastes of sugarcane bagasse, wheat bran and rice husk were used for dye and mordant extraction. It was found that by increasing the extraction temperature from 30 to 60°C, the dye yield increased. From the K/S values, it was observed that premordanting gave better colour strength than post-mordanting or meta-mordanting. The overall ratings for washing and crocking were 3-4 and 4-5, respectively. No significant antibacterial activity was observed in the dyed samples. However, excellent ultraviolet protection was observed.

Mordants (chimie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Synthetic dyes are not eco-friendly and are very hazardous to the environment, but these herbal dyes are ecofriendly and free of many types of sensitivity, allergies and environmental hazards. The present study was carried out the first time to dye the goat skin with aqueous extracts of Mangifera indica, Syzygium cumini & Eucalyptus camaldulensis. Four different types of mordants CuSO4, FeSO4, KMnO4 and Potash Alum were used to fix the dye to leather, to facilitate the take-up quality of the leather and to improve color and light-fastness. These mordant gives different shades to the leather. Fastness properties of dye were studied by different techniques i.e. washing, heating, sunlight and rubbing. Result wasevaluated by using grey scale. Results of fastness properties in all case were very excellent. Mangifera indica, Syzygium cumini & Eucalyptus camaldulensis gave different colors with four different mordants. Different colors and shades obtained from natural dyes were so light and soft.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This study is focused on the natural functionalisation of a traditional woven fabric called “Ehram”. Which is a wool based woven fabric constituted from wool yarns that are originally coloured and used in different cities of the Eastern Anatolian Region, Turkey. Because these fabrics were originally coloured (pigmented), the study aimed to functionalise them with minimal colour changes from their original colour. For this aim; lavender (Lavandula angustifolia) which is also a natural source of pleasant odour was used in finishing of Ehram. The colour changes by the application of the lavender on Ehram and the benefits that come out from the use of lavender were then analysed and presented in the study. In this respect, antibacterial activities (against Staphylococcus aureus and Escherichia coli) of dyed samples were tested within the scope of the study. In addition, colour measurements (K/S and CIE L*a*b* C* and ho) and FTIR (Fourier-transform infrared) microspectroscopy analyses of dyed fabric samples were made and microscope images were taken. It was observed that lavender with a copper-based mordanting agent can present antibacterial activity against S. aureus and E. coli in Ehram.

Tannage au chromeIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather dyeing is an essential process in the leather industry, where synthetic dyes are predominantly used. However, the environmental concerns associated with synthetic dyes have led to rising interest in natural dyes as sustainable alternatives. The use of biomordants is however, gaining attention due to their eco-friendly nature and potential to enhance dye fixation and colour fastness. This study aimed at determining the physical and fastness properties of leather dyed using natural dye extract from beetroot peels with the assistance of a biomordant derived from Acacia nilotica barks and banana pseudo stem sap. The dyeing process involved the use of the biomordant in both a pre and post-mordanting technique. Various fastness properties of dyed leather were investigated to assess the quality and durability of the dyeing process including water spotting fastness according to ISO 15700, mild washing fastness according to ISO 15703, and rub fastness (dry and wet rub fastness) according to ISO 11640. To determine the effect of the biomordant on the strength properties of the leather, the physical properties of the dyed leather were also evaluated. The tensile and tear strength of the dyed leather were measured on an Instron using IUP 6. The dye bath exhaustion was measured using spectrophotometric analysis. The dyed leatherʼs fastness properties were discovered to be good to excellent on a grey scale of 5. All of the samples exceeded the minimum recommended values (UNIDO 1996) for tensile strength (>20N/mm2), percentage elongation at break (>40%), and tear strength (>30N/mm). The samples dyed with Acacia nilotica bark as a biomordant had the highest dye bath exhaustion, followed by banana pseudo stem sap, and leather dyed without any mordant had the lowest dye bath exhaustion. According to the results obtained in this study, the use of biomordant in the dyeing of leather with natural dye from beetroot peels improved the fastness properties of the dyed leather as well as the strength of the resulting leather. Furthermore, the biomordant promoted dye uptake. Note de contenu : - MATERIALS AND METHODS : Materials - Methods - Physical properties of the dyed leather
