    Clays, nanoclays, and montmorillonite minerals
    (The Minerals, Metals & Materials Society, 2008) Faheem Uddin
    The recent introduction of nanoclays as fillers or additives in polymers for various desired effects is a subject of an increased interest for research and development to establish various applications. An increased consumption is indicated by the wider applications of clay nanocomposites approaching to almost one-quarter (24 pct) in 2005 of the total nanocomposites used. However, an interesting concern, along with the studies addressing how nanoclays change the behavior of polymeric materials, is to discover what are clays, nanoclays and montmorillonite minerals. The various structures of montmorillonite available in nature and their modification for application are discussed. An attempt is made to review the origin of using clays when nanotechnology did not exist, coupled with the effects of montmorillonite-based nanoclays on commercially known polymers.

    Wettability of easy-care finished cotton
    (Institute of Biopolymers and Chemical Fibres, 2010) Faheem Uddin; Lomas, Mike
    The easy-care finishing of cotton cross-links adjacent molecular chains in a cellulose structure, whereby the wettability of finished cotton fabric is significantly reduced or becomes unwettable. The pigment printing of easy-care finished cotton fabric was investigated. The residual catalyst content on the fibre surface and the cross-linked molecular structure both influence fabric wettability. The finished cotton fabric would become unwettable following after-wash treatment, resulting in the reduced absorption of the pigment paste in fibres. The type of catalyst used in easy-care finishing has a direct influence on pigment printing; generally, it enhances the fabric wettability of finished fabric that has received wash-off treatment. The catalyst content on the surface of fibres also affects the colour strength (K/S value) and lateral spreading of aqueous print paste on the finished fabric.
