Index. décimale : 677 Textiles Résumé : A new washing concept for wet-spun man-made fibers, where fanned fiber bundies are generated by water nozzles, is being developed. The development process is aided by CFD-Simulations and PlV-systems. In a first step conventional washing concepts are analyzed and their deficits are disclosed. The main deficit disclosed is the inhibited mass transfer of solvent in the compact fiber bundle. To overcome this deficit a method to fan the compact fiber bundie and to reduce fiber-fiber interfaces was developed. In lab scale experiments the chosen concept is reviewed. The next step in the development is the validation of the new washing concept in wet spinning trials at technical scale. Further investigations on improved box geometries are in progress.

The application of biosurfactants for scouring wool / Samuel J. Leighs in COLORATION TECHNOLOGY, Vol. 135, N° 1 (02/2019)

Langues : Anglais (eng) Catégories : Avoine et constituants Biosurfactants Fibres textiles -- Lavage Laine brute Saponines Index. décimale : 677.3 Fibres animales Résumé : The first investigation of the use of biosurfactants for the scouring of raw wool is reported. A saponin, and a recently developed surface active oat extract, were evaluated at the laboratory scale using a first-to-be-reported benchtop scouring system with simulated flowback. The levels of contaminants remaining on the wool after bioscouring, along with the wool colour, were compared with those of wool that had been laboratory-scoured with a surfactant used in the commercial scouring of raw wool, namely a synthetic nine molar poly(oxyethylene)nonylphenyl (NPEO). Both biosurfactants can be extracted from land-based renewable crops. The saponin proved to be effective, producing low levels of residual contaminants on the wool, and colours that were not statistically different to those of wool scoured with NPEO. The oat extract was considerably less effective than the saponin, both in terms of colour and residual contaminant level. This study demonstrated the significant potential of biosurfactants in the scouring of the global greasy wool clip, which now comprises two billion kg per annum.

Ultrasound-assisted enzymatic scouring of jute optimised by response surface methodology and its natural dyeing / Harshal Patil in COLORATION TECHNOLOGY, Vol. 139, N° 1 (02/2023)  

[article]  inCOLORATION TECHNOLOGY > Vol. 139, N° 1 (02/2023) . - p. 97-108 Titre : Ultrasound-assisted enzymatic scouring of jute optimised by response surface methodology and its natural dyeing Type de document : texte imprimé Auteurs : Harshal Patil, Auteur ; Sahil Mudaliar, Auteur ; Ashok Athalye, Auteur Année de publication : 2023 Article en page(s) : p. 97-108 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Décapage Fibres textiles -- Lavage Jute et constituants Le jute est une plante herbacée de la famille des Malvacées, cultivée dans les régions tropicales pour ses fibres. Jute est aussi le nom donné à ces fibres textiles, appelées aussi chanvre de Calcutta. Nom scientifique : Corchorus capsularis L., famille des Malvacées, sous-famille des Grewioideae ; la classification classique le situe dans la famille des Tiliacées. Une plante voisine, Corchorus olitorius L., la corète potagère, est aussi utilisée aux mêmes fins.

The use of white biotechnology involving enzymes for the efficient processing of jute is considered to boost its productivity. The present investigation deals with the pretreatment of jute by using ultrasound-assisted enzymatic scouring followed by bleaching and dyeing. The process showed optimum removal of impurities and improved water absorption capacity with minimal damage to fibre tensile strength. The process parameters and conditions were determined by response surface methodology, where weight loss of jute was kept as the main response. The optimised recipe obtained was 2.8% enzyme concentration, 1 g/L wetting agent at 55°C for 10 minutes at an ultrasound frequency of 40 kHz. The optimised recipe was compared with conventional high-temperature long-duration enzymatic scouring and was found to have an equal performance. Further, the scoured jute was dyed with a natural dye extracted from sappan wood and madder. Fourier Transform-infrared analysis was used for characterisation. The wash and light fastness of dyed jute yarn were evaluated and found to meet the industry norms.
