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.

  • Examination of nanoparticles used for textile applications
  • Characterization of nanofibers with diameters less than 200nm

  • 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.

  • Analysis of surface morphologies in 3D for fabrics in the nanoscale level

  • Analysis of basic structural parameters of textile products such as thickness, hairiness and number of twists
  • Analysis of fabric defects
  • Fabric structure analysis

  • Analysis of composition, thermal stability of textile materials (such as textiles, fibres filaments, threads, paints, pigments etc.)
  • Analysis of moisture and ash content in textiles

  • Analysis of glass transition temperatures, melting behaviour, reaction enthalpies and effect of fillers in textile materials.
  • Analysis of thermal transition values of textiles, pigments and paints

  • For the characterization of viscoelastic behaviour (modulus values) of textile materials with respect to temperature

  • Identification of chemical functionalities present in textiles
  • Identification of textile fibre types
  • Contamination analysis for textile materials
  • Identification of surface chemical structures of textile materials
  • Analysis of IR absorption behaviour of textiles

  • Used to analyse and differentiate types of fibres and different types of dyes used in textiles

  • Analysis of the particle sizes and stability of dyes, pigments, emulsions and colourings used in textile industry

  • Used to analyse colour properties of textiles, textile chemicals, dyes etc.

  • Characterization of optical brightness, fluorescence and phosphorescence

  • Used to analyse crystalline phases of textile materials (for identification of fibres)
  • To obtain information regarding internal structure of textile fibres and spacing between the lattice structures

  • Solid state NMR for the analysis of chemical functionalities in textile materials (yarns fabric fibres etc.)

  • Quantitave or qualitative analysis of the of elements in textile materials, dyes, paints etc

  • Qualitative analysis of the elemental composition of fabrics/ textile materials from 11Na to 92U
  • Elemental mapping of textile materials

  • To determine the C, H, N and S content of textile materials

  • Used in the identification of elemental composition at certain areas/points in a fabric/ a fibre
  • Used in the elemental mapping of textile materials

  • Analysis of the particle sizes and stability of dyes, pigments, emulsions and colourings used in textile industry
