(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 ...
La tesi que ens ocupa, parteix de I'interes de blanquejar pasta kraft d'eucaliptus a traves de tecnologies netes, es a dir, utilitzant metodes mes respectuosos pel medi ambient. La motivacio per a la realitzacio d'aquesta ...
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 ...
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 ...
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 ...
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 ...
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 ...
(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 ...
(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 ...
(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 ...
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 ...
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 ...
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 ...
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 ...
