  • Topochemical modification of Cotton Fibres with carboxymethyl Cellulose
    Cellulose, 2008
    Co-Authors: Lidija Fras Zemljič, Per Stenius, Janne Laine, Karin Stana-kleinschek
    Abstract:

    Adsorption of carboxymethyl Cellulose (CMC) as a method to introduce charged (ionizable) groups onto Cellulose Cotton Fibre surfaces was investigated. The method was based on application of a previously published method used for wood Fibres. The amount of adsorbed ionizable groups was determined indirectly by analysis of CMC in solution by the phenol–sulphuric acid method and directly by conductometric titration of the Fibres. Results from the two methods correlated well. The molecular weight and purity of the CMC had an influence on its adsorption onto Cotton; high molecular weight CMC was preferentially adsorbed. The adsorbed charge correlated linearly with the amount of CMC adsorbed. The total charge of the Cotton Fibres could be increased by more than 50% by adsorption of CMC. It is expected that this modification procedure can be used in a wide spectrum of practical applications.

  • Enzymes in Fabric Preparation: How much are we Successful?
    Journal of Textile Science & Engineering, 2014
    Co-Authors: D Saravanan
    Abstract:

    The role of Cotton, wool and silk Fibres in apparel segment of the textile industry has been robust in all these years. Cotton Fibre has a dominant role in the apparel segment even though many alternative, regenerated cellulosics Fibres are available. Besides Cellulose, Cotton Fibre contains many constituents are systematically eliminated in the fabric preparation process to facilitate dyeing and finishing. Preparatory processes assume the centre stage, in entire process sequence of fabrics due to high water, chemicals, energy requirements. Enzymes provide sustainable solutions, in operations that require more amounts of energy, at relatively low energy levels with meagre amount of auxiliaries. Reviews and reports have been frequently published to demonstrate the advantages of enzyme based processes in comparison with chemical treatments. Both bacterial and fungal sources suffice requirement of various enzymes used in textile applications.
