AITEX is constantly working on the development of R+D+I projects related to biotechnology and its uses in textile products and processes in the fields of cosmetics, natural products and the encapsulation of active compounds. The Institute has a full suite of services backed by the most complete infrastructure to develop projects in the following fields of research:

  • Encapsulation
    • Fluid Bed
    • Spray Drying
      • Micro
      • Nano
    • Extrusion
    • Membrane
  • Characterisation
    • Z Potential
    • Particle size


  • Functional fibres

The incorporation of a range of functional properties to natural and synthetic fibres via different procedures:

  • The surface modification of synthetic fibres using enzyme technology
  • The incorporation of chemical groups to natural fibres
  • The additivation of functional active compounds
  • The use of biopolymers


  • Biotechnology applied to industrial textile processes

The application of biotechnology to manufacturing processes and lines of research in the textile industry.  

  • Biopolymers and new fibres
  • Modifying fibres and surfaces using enzyme treatment
  • The functionalisation of substrates
  • Dyes, colourings and intermediate products
  • Treating waste water and sludge, etc.


  • Environmental

This line of research looks at treating textile waste water and sludge from the finishing sector and works specifically on:

  • Breaking down azo dyes in waste water
  • Fixing enzymes
  • Biofilters
  • Recovering unused dye from the dye bath for reuse
  • The encapsulation of bio fungicides, nutrients and phytostrengtheners for use in geo-textiles
  • The development of textile substrates for soil stabilising and reforestation applications


  • Cosmetics and hygiene

The use of encapsulation to improve the stability of active compounds such as fungicides, aromas and enzymes among others and to provide the substrate with a slow-release capability.

  • Micro/nano-encapsulation
  • Hydrogels
  • Cyclodextrins
  • Zeolites


  • Health and hygiene

Technical textile solutions for medical textiles, an emerging sector with huge potential for innovation.

  • Hydrogels used in textile engineering
  • Functionalising dressings
  • Fixing bioactive molecules
  • Biosensors
  • The encapsulation of active compounds
