Titre : Dyestuff developments Type de document : texte imprimé Auteurs : C. S. Tysoe, Auteur Année de publication : 1995 Article en page(s) : p. 67-75 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The paper outlines the continuing trend towards the development of specialised metal complex dyestuffs and the importance of newly developed liquid versions, their production and advantage for the tanner over conventional powder versions.
A brief review is included of the relative importance of the Colour Index, dyestuff availability and classification methods. Also, extended "trichromatic" dyeing systems are discussed as an intermediate stage, which have lead to the latest dyestuff developments, together with the implications of this for stage, which have lead to the latest dyestuff developments, together with the implications of this for CCMP (Computer Colour Match Prediction).
Factors affecting colour uniformity are mentioned and the mentioned and the numerous differences that have been observed between the modified metallised powder and liquid dye ranges are also highlighted. The paper concludes indicating the four major 'classes' of dyestuffs currently available inliquid form and considers how these can be exploited for the benefit of the leather manufacturer.En ligne : https://drive.google.com/file/d/1Jzdiqpvcn0--REE5odtCLARsdTqEYle1/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8202

Titre : Dying facility modernization Type de document : texte imprimé Auteurs : R. H. Hankey, Auteur ; J. F. Loxston, Auteur Année de publication : 1999 Article en page(s) : p. 84-88 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The fundamental objectives behind the project were to rationalise the management system and to modernise the dyeing facilities. Three key topics: people, process, and equipment were studied. People: The abilities of each individual in various subjects were assessed with respect to technical ability, team working, and communication skills. Training was then implemented, where necessary, to ensure a competent close working team was formed. Process: Processes were scrutinised, new approaches were taken up with regards to robustness and simplification. This constituted the need for increased research and development and process monitoring in bulk production. Equipment: This involved assessing different types and constructions of dyeing vessels, determining the correct quality of process water and assessing computer colour match prediction systems. It also meant sourcing a control system capable of controlling chemical additions (including water) along with vessel operation which provides historical data manipulation. From the completed project the building of a new dyeing facility was implemented. This involved 18 new wooden dyeing drums complete with recirculation, filtration and automatic drain valves. In addition, all pumpable chemicals including water are automatically added by computer control. Filtering and softening the process water supply has also been completed. As a result of this modernization, the following improvements have been seen: reduced labour costs, greater consistency, refined processes, reduced production costs, increased production efficiencies and reduced environmental impact.

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Finishing is one of the significant steps in the process by which the tanning industry transforms leather into an end-product. Therefore, a deep study of the finishing system is necessary to help the control of this step and bring innovation to the finishing process. Based on principles of dynamic light scattering (DLS) and zeta potential, the stability of a leather finishing system was investigated. Polyrethane and acrylic resin were used to prepare a single finishing system and wax emulsion, silicone oil and pigment paste were added to the single finishing system to make three binary finishing systems, then a ternary system was prepared by adding was emulsion and silicone oil to the single finishing system.
The particle size and zeta potential of the single, binary and ternary finishing systems were characterized using the zetasizer nano-ZS (Malvern Instruments Ltd., UK). The results showed that the stability of the finishing system was not affected with the addition of was emulsion and silicone oil, because the zeta potential was always greater than 30mv, however ; a significant decrease of zeta potential was observed due to the addition of pigment to the finishing system, which indicates a decrease of the finishing system's stability. The results provide a comprehensive and theoretical understanding of the interactions among materials in a finishing system.Note de contenu : - EXPERIMENTALE PROCEDURE : Materials - Preparationof samples for the test of particle size and zeta potential - Measurement of particle size distribution and zeta potential of finishing system

Simulation par ordinateurIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this paper, a single bioflocculant was used to treat nitrogen in tannery wastewater. At different processing time points, the nitrogen concentrations for the total nitrogen, ammonia, Kjeldahl nitrogen, nitrate, and nitrite were determined. Furthermore, a computer simulation was performed to derive the experience dynamic equations.
The established dynamic equations can be used to predict the removal capacity of the total nitrogen, ammonia, Kjeldahl nitrogen, nitrate, and nitrite in the tannery wastewater treated with the biofloccufant, calculate the optimum processing time, and cut costs. In addition, these equations establish a foundation for studying the mechanism underlying this bioflocculant treatment for tannery wastewater.Note de contenu : - EXPERIMENTAL PROCEDURE : Materials - Strain - Media preparation - Bioflocculant preparation - Tannery wastewater treatment by the bioflocculant

Titre : Early detection of grain faults during wet processing Type de document : texte imprimé Auteurs : K. T. W. Alexander, Auteur ; M. P. Walker, Auteur ; R. M. Webster, Auteur ; A. Bugby, Auteur Année de publication : 1990 Article en page(s) : p. 191-211 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : With the growing demand for high-quality full-grain leathers and the necessity to minimise costs of re-working, the need for accurate and reliable sorting of semi-processed stock is becoming increasingly important.
During recent studies at the British Leather Confederation,a wide range of high- and low-technology approaches has been investigated to determine whether they have any potential to detect grain damage. This has led to the development of the 'Sortassist' process based on a decolorisable pigment that effectively highlights grain faults on wet blue(75 to 85 percent detection rate) or pickled stock(over 95 percent detection rate).
The pigment formulation can be applied either manually or by drum at pH>4. After grain sorting, the pigment is decolorised and chemically destroyed by a short acid-treatment step at pH<3, prior to further processing of the stock.En ligne : https://drive.google.com/file/d/1jzaDUaI72sXmrEfiuFUFsgKhVYuGxAet/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8660
