Analysis of the influence of false twist integrated into a high speed drafting system of an air jet spinning machine
(English) Air jet spinning is an emerging technology, already well established in the textile market. The commercial success increased over the last decades and intensified the research and innovation approach in the field ...
Preparación de soportes biomateriales con estructuras fibrilares obtenidas mediante electro-hilatura
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 ...
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, ...
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 ...
Surface functionalization of cellulosic substrates by using chemical and biotechnological methods
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 ...
Tratamiento y reutilización de efluentes de la industria textil mediante técnicas de membranas
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, ...
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 ...
Treatment of textile surfaces by plasma technology for biomedical applications
Medical applications of technical textiles are an expanding field of research. One of the added values of these new materials would be that they were suitable to contain and release active compounds in a controlled and ...
Nuevas perspectivas sobre la evaluación del cayente de los tejidos de calada
Drape indicators reported by textile researchers from 1950 to 2013 are examined. A total of 36 indicators were identified that are described in detail as regards geometric principle and calculation in order to unify existing ...
Modelling drug delivery mechanisms for microencapsulated substances applied on textile substracts
Mathematical drug release modelling of biodegradable polymeric systems by microencapsulation technology in textiles has not progressed much yet, because it is generally too complex. The release of a therapeutic agent from ...
Quantificació numérica de les emocions associades al color
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 ...
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 ...
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 ...
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 ...
Métodos físico-químicos de caracterización de las fibras de polilactida
The interest of studying this fiber resides in the fact that it is a biodegradable polymer that is obtained from annually renewable resources, besides being a fiber that is beginning to be introduced in the market. Nowadays ...
Filamentos elásticos de elastolefina de alta durabilidad obtenidos a partir de copolímeros de bloque de etileno-octeno de baja densidad mediante la tecnología de polimerización por transferencia de cadena para aplicaciones en indumentaria de uso profesional
En la actualidad el mercado carece de prendas elásticas para uso profesional puesto que los elastanos habitualmente utilizados son inestables frente a altas temperaturas y químicos agresivos, e.g. termofijado, mantenimiento ...
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 ...
Flax fibre modification using enzyme systems to obtain high-value cellulose products
The aim of this thesis is to modify flax pulp fibres (Linum usitatissimum) by more friendly environmental processes. Pulp and paper research is focussing through enzyme systems investigation for developing green ...
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 ...
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 ...
