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 various requirements regarding their eventual performances.
The application of textiles is indeed 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 investigates techniques in both production steps by studying bi-component yarns and various eco-friendly surface treatment techniques, coating techniques and energy saving (yarn) coating curing techniques.
In the field of materials for surface treatment and functionalisation, Centexbel develops functionalised hotmelt coating for the production of FR, antistatic and hydrophobic/hydrophilic textiles for which it also prepares the functionalised compounds.
The Hydrotex project focuses on the functionalisation of textiles by applying hydrogels. These hydrogels are capable of absorbing and releasing moisture in a reversible way resulting in optimised insulating properties. Hydrogel textiles are therefore suited for protective clothing, mattress ticking...
Centexbel also endeavours to functionalise yarns and textile surfaces by applying additives in extrusion and coating formulations, such as ICP (intrinsic conductive polymers) and carbon nanotubes to increase conductivity and nanosilver particles for antibacterial properties.
Surface functionalisation is a research field to be explored in collaboration with textile companies, for example in respect of the suitability of plasma treatment in specific textile processes to obtain hydrophobic properties or to improve adhesion.
