      Comunicació de congrés
      Accés restringit per política de l'editorial
      The aim of this work was to study the effect of treatment of EMPA standard cotton fabric with UV-C radiation to determine the performance of detergency with treated and untreated fabric, as well as redeposition of impurities ...

    • Experiences in the air spinning to manufacture medical devices 

      Marsal Amenós, Félix (2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The work aims to determine, with scientific rigor, differences in key parameters of the yarns produced by conventional ring spinning systems, open-end and air spinning and its interrelation with the main parameters of those ...

    • Discolouration of dyed fabrics on one side without chemicals 

      Carrión Fité, Francisco Javier (2015)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The subject of this work was the discolouration of one side of dyed cotton fabric using UV-C radiation, testing for fastness to that external radiation agent. This was studied through selection of different dyes used for ...

    • Reuse of textile effluents treated with nanofiltration membranes 

      Vilaseca Vallvé, M. Mercedes; Buscio Olivera, Valentina; García Jiménez, María Gracia; Crespi Rosell, Martin; Gutiérrez Bouzán, María Carmen (2015)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The reactive dye Cibacron Yellow S-3R was selected for the membrane filtration study, to evaluate the feasibility of nanofiltration membranes to treat textile wastewater. Synthetic effluents were treated by means of two ...

    • Influencia del tratamiento superficial del algodón en su lavado 

      Carrión Fité, Francisco Javier (2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      El objetivo de este trabajo fue obtener el efecto del pretratamiento de tejido de algodón standard EMPA mediante radiaciones UV-C, con objeto de obtener su comportamiento diferenciado respecto al tejido sin tratar, frente ...

    • New strategies to bleach dissolving pulps using enzymatic treatments 

      Quintana, Elisabet; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2014)
      Text en actes de congrés
      Accés obert
      A biobleaching sequence was applied to sulphite pulp in order to explore new bleaching possibilities using enzymatic treatments. Therefore, the well-known laccase-mediator system was used with the aim to achieve dissolving ...

    • Enhancing profitability of a spinning 

      Marsal Amenós, Félix (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Systematic control of the rheological behavior of the rovings in an installation facility dynamometer constant elongation gradient is proposed in this paper. It is an application for all types of spinning both short fibers ...

    • Evaluating changes on cellulosic biobleached fibers by means of thermogravimetric analysis 

      Quintana, Elisabet; Garcia Barneto, Agustín; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Ariza, J.; Roncero Vivero, María Blanca (2014)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The effects on fibre surface produced by the laccase-mediator system on softwood sulphite fibres were analysed in terms of surface crystallinity using thermogravimetric analysis. The starting pulp presented low content of ...

    • Monitoring oxidation-reduction potential of laccase-mediator system: can the efficiency of a redox mediator for deslignifying kenaf pulp be predicted? 

      Andreu Terrén, Glòria; Vidal Lluciá, Teresa (2014)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The oxidative ability of five phenolic compounds (acetosyringone, syringaldehyde, p-coumaric acid, vanillin and actovanillone) and the laccase–mediator systems was determined by monitoring the oxidation–reduction potential ...

    • Using glycosidases to modify TCF bleached specialty sisal fibers 

      Beltramino Heffes, Facundo; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2014)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Modifying fibers in order to upgrade them to dissolving grade involves several changes. Paper grade pulps can be used to yield this kind of raw materials, if the necessary modifications are carried out. Classic processes ...

    • Biografting of ferulic acid onto lignocellulosic fibers by the use of laccases
