  • novel Cotton cellulose by cationisation during the mercerisation process part 1 chemical and morphological changes
    Cellulose, 2014
    Co-Authors: Anita Tarbuk, Ana Marija Grancaric, Mirela Leskovac
    Abstract:

    Cationisation is the modification of Cotton cellulose by using quaternary ammonium compounds that block negative OH groups, thus resulting in electropositive Cotton cellulose. It is an alternative method for achieving better adsorption of chemical compounds and substances, such as dyestuffs, fluorescent whitening agents, and other textile auxiliaries. The cationisation of Cotton cellulose changes the surface electrical charge (electrokinetic potential) by significantly increasing its adsorption properties. The presented article investigated the chemical and morphological changes in Cotton cellulose when cationised with an epihalohydrin, 2,3-epoxypropyl trimethyl ammonium chloride, after and during the mercerisation process. When comparing Mercerised Cotton with cationised Cotton, it was concluded that cationisation during the mercerisation process using short-chain cationic compounds would result in a novel Cotton cellulose that would bring a new dimension to Cotton pre-treatment and finishing. The modified Cotton would retain all the beneficial properties of Mercerised Cotton with a change of surface charge that would ensure further improvement in quality.

  • Novel Cotton cellulose by cationization during mercerization—part 2: the interface phenomena
    Cellulose, 2014
    Co-Authors: Mirela Leskovac
    Abstract:

    Cationisation during the mercerisation process with an epihalohydrin results in novel Cotton cellulose that gives a new dimension to Cotton pre-treatment and finishing. The modified Cotton retains all the beneficial properties of Mercerised Cotton with a change of the surface charge that ensures further quality improvement. The present paper deals with systematic investigations of the interface phenomena of cationised Cotton fabric with an epihalohydrin; 2,3-epoxypropyl trimethyl ammonium chloride during and after mercerisation process. The water, ionic surfactant and dyestuff adsorption, as well as surface free energy, electrokinetic potential, isoelectric point and point of zero charge determined according to the streaming current/streaming potential method; and specific amount of surface charge of modified Cotton fabrics are researched.

When comparing Mercerised Cotton with cationised Cotton, it was concluded that cationisation during the mercerisation process using short-chain cationic compounds would result in a novel Cotton cellulose that would bring a new dimension to Cotton pre-treatment and finishing. The modified Cotton would retain all the beneficial properties of Mercerised Cotton with a change of surface charge that would ensure further improvement in quality.

  • graft polymerisation of functional acrylic monomers onto Cotton fibres activated by continuous ar plasma
    Plasma Processes and Polymers, 2006
    Co-Authors: Valter Castelvetro, Enrico Fatarella, Leopoldo Corsi, Simone Giaiacopi, Gianluca Ciardelli
    Abstract:

    Continuous cold Ar plasmas were used to activate the Mercerised Cotton fabric towards surface-initiated graft polymerisation of glycidyl methacrylate, 2-hydroxyethyl methacrylate (HEMA) and 1,1,2,2-tetrahydroperfluorodecyl methacrylate (XFDMA). Single and multi-step processes, carried out either in the plasma chamber (one-step and two-step processes) or ex situ after plasma treatment, were explored to optimise the grafting efficiency, The mechanical properties of the grafted Cotton were substantially unaffected. Grafting with XFDMA gave good results only when the plasma activation was performed on monomer-impregnated fabrics, as shown by gravimetry, ATR FT-IR spectroscopy, and water and oil repellence tests. On the contrary, with HEMA better results were obtained by in situ grafting from monomer vapours.
