Langues : Anglais (eng) Catégories : Antioxydants Déchets végétaux -- Recyclage Marrons et constituants Mordançage (teinture) Résistance au lavage Résistance au rayonnement ultraviolet Riz et constituants Soie et constituants Solidité de la couleur Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : In order to reutilise the byproducts of foods and crops to benefit the environment and economise on resources, the natural extracts from chestnut shell and black rice bran were applied in the simultaneous dyeing and multifunctionalisation of silk fabrics. In this work, the influence of pH value on dyeing properties was studied. The effects of the ratio of chestnut shell and black rice bran extracts and the application of mordants (aluminium potassium sulphate and ferrous sulphate) on the dyeing performance as well as anti-ultraviolet and antioxidant properties of treated silk were also discussed. The results showed that deep-coloured silk fabrics can be obtained when dyed with the two natural extracts as the pH value of the dyebath approached 3. The ratio of the two natural extracts and the use of the mordants have significant effects on colour depth, colour hue, colour fastness, and the functionalities of dyed silk fabrics. Combination dyeing and mordanting are able to enrich the colour hues of dyed fabrics. The washing, rubbing, and light fastness of the dyed fabrics after mordanting can be rated higher than grade 4. Moreover, the silk after combination dyeing has good UV protection performance (UPF > 30) and antioxidant activity. In addition, the functionalities of treated fabrics showed excellent washing fastness. This study reveals that chestnut shell and black rice bran extracts are suitable as natural colourants and multifunctional finishing agents for the preparation of coloured and multifunctional silk materials.

Can silk become a fashionable polymer-reinforcing fibre ? / Darshil U. Shah in JEC COMPOSITES MAGAZINE, N° 92 (10-11/2014)  

[article]  inJEC COMPOSITES MAGAZINE > N° 92 (10-11/2014) . - p. 47-50 Titre : Can silk become a fashionable polymer-reinforcing fibre ? Type de document : texte imprimé Auteurs : Darshil U. Shah, Auteur ; David Porter, Auteur ; Fritz Vollrath, Auteur Année de publication : 2014 Article en page(s) : p. 47-50 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Composites à fibres naturelles Soie et constituants Index. décimale : 668.4 Plastiques, vinyles Résumé : While silks have long been (and incorrectly) hyped for use in ultra-light bullet-proof vests, they have found some niche technical applications (e.g. high-end tubular tyres and "ballistic boxers"). Yet, today's silks are still predominantly used in garments and textiles. However, the Oxford Silk Group's recent studies are suggesting that nature's wonder-fibre silk is a strong natural fibre candidate for reinforcement in polymer composites.

Alum, ferrous sulfate, stanium chloride, calcium nitrate, and potassium bitartrate were used as mordants. Reversed-phase high-performance liquid chromatography with diode-array detection was utilised for identification of the dyes present in the dyed silk fabrics and the plant extracts. The extraction of dyes was carried out with a hydrochloric acid/methanol/water (2:1:1 v/v/v) mixture. The colour coordinates and K/S values, as well as wash, light, and rub fastness, were determined.

A comparative study of ultrasonic degumming of silk sericin using citric acid, sodium carbonate and papain / Wuchao Wang in COLORATION TECHNOLOGY, Vol. 135, N° 3 (06/2019)  

[article]  inCOLORATION TECHNOLOGY > Vol. 135, N° 3 (06/2019) . - p. 195-201 Titre : A comparative study of ultrasonic degumming of silk sericin using citric acid, sodium carbonate and papain Type de document : texte imprimé Auteurs : Wuchao Wang, Auteur ; Yi Pan, Auteur ; Kang Gong, Auteur ; Qi Zhou, Auteur ; Tonghua Zhang, Auteur ; Qing Li, Auteur Année de publication : 2019 Article en page(s) : p. 195-201 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dégommage Essais dynamiques Fibres textiles -- Analyse Fibres textiles -- Propriétés mécaniques Morphologie (matériaux) Nettoyage par ultrasons Résistance à la traction Séricine Soie et constituants Surfaces -- Analyse Index. décimale : 667.3 Teinture et impression des tissus Résumé : The utilisation of ultrasonics has been shown to enable efficient and environmentally friendly textile wet processing. This study conducted a comparative investigation of silk degumming by using a conventional heating bath and ultrasonic irradiation at a range of ultrasonic frequencies. Citric acid, sodium carbonate and papain were used as degumming agents. Sericin degumming rate, fibre whiteness, fibre surface morphology, fibre structure characteristics and fibre tensile properties were measured and analysed. Results showed that ultrasonics at a lower frequency produced a greater degumming rate than at a higher frequency. Ultrasonics is a more effective way than the conventional heating bath of improving degumming efficiency, especially at a lowered temperature of 60 °C. When sodium carbonate was applied at 90 °C, a conventional heating bath was found to be more effective than ultrasonics. Papain was found to be more effective in sericin removal than citric acid and sodium carbonate, with a degumming rate of 22% achieved at 60 °C under ultrasonic irradiation at 40 kHz. The use of papain can, however, cause a possible overreaction to silk under certain severe conditions, resulting in a loss of fibre whiteness. Negligible changes in fibre structure characteristics were measured by Fourier Transform–infrared spectroscopy and X‐ray diffraction after ultrasonic degumming with papain. Slightly reduced fibre strength and increased fibre extensibility were observed in ultrasonically degummed silk samples compared with un‐degummed and conventionally degummed silk samples.

Langues : Anglais (eng) Catégories : Colorants réactifs Fibres cellulosiques Fibres textiles Fibres textiles synthétiques Laine Polyamide 66 Polyamides Un 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. Soie et constituants Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : This review describes the immense impact of reactive dyes on the textile industry. Their use on cellulosic fibres is especially important, but their growing popularity on polyamide substrates is notable. Detailed information is given about developments both in the chemistry of reactive systems and in the chemical technology involved in their application to a variety of fibre types. It is also pointed out that further research is necessary to improve dye–fibre fixation efficiency, especially when dyeing full shades on cellulosic fibres. This work is necessary to address the current environmental problem of colour in dyehouse effluent. The potential solutions reviewed include multifunctional reactive dyes, cationic reactive dyes, and cellulose fibre modification.
