Applications in Textiles

Application in Textiles

The design, manufacture and export of textiles and apparel products is one of the biggest industries in Sri Lanka, and one which plays a key role in advancing the country’s economy. Sri Lanka has built its competitive edge on value-addition rather than cheap production cost, with greater emphasis on product quality and its ability to manufacture niche products. We offer several analytical techniques for textiles such as surface and structural characterisation of fibres, yarns and fabrics. We can determine the thermal stability and thermal transitions as well as provide qualitative and quantitative analysis of elemental compositions of textiles, paints and pigments. Some textile applications that are possible to be carried out at the SLINTEC premises using the equipment available for analysis are given below.

Transmission Electron Microscopy (TEM)
  • Examination of nanoparticles used for textile applications
  • Characterization of nanofibers with diameters less than 200nm
Scanning Electron Microscopy (SEM)
  • Structural characterization of fibres in textiles/yarn/fibres etc.
  • Surface characterization of fibres in textiles etc.
  • To analyse fabric/textile defects
  • Examination of nanoparticles/microparticles used for textile applications
  • SEM along with EDX analysis allows the subjective identification and qualitative analysis of elements at certain areas/points in a fabric/ a fibre etc.
Atomic Force Microscopy (AFM)
  • Analysis of surface morphologies in 3D for fabrics in the nanoscale level
Optical Microscopy
  • Analysis of basic structural parameters of textile products such as thickness, hairiness and number of twists
  • Analysis of fabric defects
