Surface functionalisation

Hyper-functional textiles for the most diverse applications

In addition to their intrinsic properties (flexibility, drapability, permeability, barrier properties, strength, elasticity…) textiles offer a large “surface” to be functionalised to comply with the requirements regarding their performances.

The application of textiles is closely related to the presence (combination) of different surface properties, making the product even more attractive to other industrial sectors, from construction over automotive to surgical applications (e.g. scaffolds for tissue engineering) and space travel.

Centexbel studies and tests new techniques, materials and additives to improve the surface properties in view of the development of high-quality textile products to be introduced in new and interesting applications and markets.

Textile materials can be optimised and functionalised both during the extrusion phase and textile finishing phase. Centexbel focuses its research and process optimisation on eco-friendly techniques.

Examples:

  • functionalised hotmelt compounds for the production of flame retardant, antistatic and hydrophobic/oleophobic textiles
  • hydrogels absorbing or releasing moisture under the influence of temperature. This reversable process increases the insulating properties of textiles for applications in protective clothing, mattress ticking, etc.
  • yarn and textile functionalisation by means of additives in extrusion or coating formulations: ICP (instrinsically conductive polymers) and carbon nanotubes to improve electric conductivity; nanosilver particles for antimicrobial textiles
