Industrial effluents and their further reuse have shown an increasing interest. The current PhD Thesis is based on obtaining a new system for the treatment of textile effluents. The aim of this study is to remove colour ...
The worldwide poultry industry generates a large amount of wastes which, accordingly to the current law, are mostly discarded. These wastes include chicken feathers, keratin structures which 109.056.179 ton were generated ...
La present tesi s’emmarca dins d’una de les línies del Grup de Recerca Paperer i Gràfic (CIPAGRAF), del Departament d’Enginyeria Tèxtil i Paperera de l’Escola Tècnica Superior d’Enginyeries Industrial i Aeronàutica de ...
Objetivos de la Tesis:<br/><br/>El objetivo principal de la presente Tesis, Cinética de Tintura de Tencel ,se centra en dos objetivos parciales: la sensibilidad a la temperatura y el efecto de la variación de la concentración ...
From a long time, finishes have been developed with fragances; despite this fact, whatever the technology used to obtain the fragrance formulation, the final effect on the odor is very low. The smell usually disappears ...
Composite materials offer good mechanical performance with lower weight than classical materials, what has encouraged their use in many industry applications. Moreover, the rising awareness about environmental problems has ...
This thesis is based on the study of colour elimination of textile effluents which contain reactive dyes. Reactive dyes are widely used in the dyeing of cotton and other cellulosic fibre. However they exhibit a low degree ...
La celulosa es el polímero más abundante en la Tierra y en los últimos años ha ganado un amplio interés como fuente de nuevos productos con requisitos de procesamiento y de calidad diferentes a los procesos convencionales ...
In the current scenario of growing environmental concerns, the search for innovative, renewable, non-polluting materials has never been as intensive as it is today. Cellulose, being the most abundant polymer on earth, ...
In 1931, the first research work related to microencapsulation was published, in which a microcapsule formation technology using gelatine as a wall material was described by a process called "coacervation". The interest ...
La motivació per a la realització d'aquest projecte sorgeix de la problemàtica ambiental ja coneguda que existeix amb relació a la contaminació produïda pels reactius utilitzats en el blanqueig de pastes per a paper, i per ...
The fabrication of scaffolds materials with the ability to mimic the structural and functional properties of extracellular matrix is one of the most important points of interest into the tissue engineering field. Among the ...
Vivim en un món de color. Tot té un color. El fet que tinguem receptors tan específics per a l’estímul del color ens confirma la importància que té per als éssers humans. Responem al color, de manera activa o passiva, en ...
This thesis deals with the surface modification of cellulosic substrates by use of chemo-enzymatic methods. Functionalizing cellulose is intended to adjust its properties for various purposes, but particularly for obtaining ...
Textile industry consumes large amount of water in their processes, mainly in dyeing and finishing operations. In general, during the dyeing process, up to 30% of dyes used can be discharged into wastewater. For this reason, ...
