Aplicació de tècniques electroquímiques i fotoelectroquímiques per la degradació de compostos poc biodegradables en efluents industrials tèxtils.
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 ...
Aplicación de biotecnología para la obtención de pastas de alta calidad. Estudio de sistemas enzimáticos en secuencias de blanqueo respetuosas con el medio ambiente
La presente tesis parte del interés de blanquear pasta de lino (Linum usitatissimum) mediante procesos más respetuosos con el medio ambiente, a partir de secuencias totalmente libre de cloro (TCF) y de la utilización de ...
Aportaciones al desarrollo preclínico de un medicamento oncológico infantil con excipiente o soporte textil
The world of technical textiles is present every day in more sectors. In the work presented, a new facet of textile materials has been shown, textiles as a drug excipient and functional matrix. It is known that electro-spinning ...
Application of laccase-based systems for biobleaching and functionalization of sisal fibres
This research project originated from interest in assessing the potential of enzyme technology (particularly laccase-based systems) for the biomodification of sisal specialty fibres by using environmentally friendly ...
Avaluació d'alternatives industrials per a l'obtenció de nous materials que valoritzen residus queratínics
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 ...
Blanqueig enzimàtic de pasta de kenaf emprant sistemes lacasa-mediador
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 ...
Comportamiento cinético de fibras Tencell con colorantes directos
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 ...
Desarrollo de microcápsulas rígidas de fragancia y de técnicas que permitan la cuantificación de la eficiencia de encapsulación
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 ...
Desarrollo de nuevas estructuras laminares de nanocelulosa con propiedades avanzadas para el packaging
(English) Changes in the use of raw materials and major lifestyle changes in first world societies have driven the massive use of petroleum-based materials in a wide range of applications. Plastic waste has become pervasive ...
Development of dynamic textiles based on shape memory polyurethane (SMPU) for applications in car seat upholstery
(English) In recent years, numerous studies have been carried out on functional textiles due to their ability to adapt and interact with the environment. In particular, special focus has been placed on dynamic textiles ...
Development of high performance cement-based composites reinforced with nonwoven fabrics from sustainable raw materials and textile wastes
(English) Currently there is a growing concern about the sustainability of the construction sector due to its great contribution to climate change. Approximately one third of carbon dioxide emissions are produced by this ...
Development of new lightweight green composites reinforced with nonwoven structures of flax fibres
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 ...
Electroquímica, UV i altres tècniques aplicades a la decoloració i reutilització d'efluents de tintura amb colorants reactius
En aquesta tesi s’estudien diverses tècniques per a la decoloració d’efluents de tintura amb colorants reactius i per a la reutilització dels efluents decolorats en noves tintures. Les tècniques utilitzades per eliminar ...
Eliminación del color de las aguas residuales procedentes de la tintura con colorantes reactivos
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 ...
Enzymatic and chemical treatments to obtain pulps with high-cellulose content
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 ...
Enzymatic-assisted preparation of nanocrystalline cellulose from non-wood fibers
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, ...
Estudio de la influencia de los diferentes parámetros involucrados en la microencapsulación mediante coacervación compleja
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 ...
Estudio de la viabilidad del uso de una mezcla fenol/agua en el ensayo de solubildad diferencial del poliéster
In the manufacture of polyester fiber, first takes place the synthesis of the polymer, and subsequently the spinning and stretching of the fibre. The conditions to which these processes occur, such as temperature, drawing ...
