Research into these materials, used in civil engineering projects, looks at the products from every aspect to ensure that they meet all current legislation. Working in close collaboration with industrial partners, new geosynthetic materials and structures are developed: geotextiles, geomeshes, geonetting, geoblankets, geocells, geocomposites and more efficient geosynthetic barriers with a range of different applications.
Lines of R & D:
Optimisation of combinations of different polymers and additives for the subsequent extrusion of textile fibres through the fusion spinning process.
The use of polymers taken from renewable resources offers new possibilities for the textile sector. For example, the extrusion of polylactic acid (PLA), polyhydroxybutyrate (PHB), thermoplastic starch (TPS) and different combinations for applications as diverse as home textiles or in technical markets such as geotextiles or the automobile industry, are gaining ground over other ‘commodity’ polymers in certain applications. In this regard, formulations modified with plastifying agents are optimised in order to achieve textile fibres.
Obtaining mono and dual component multifilament fibres broadens the horizon of possibilities for usage in diverse fields such as health/hygiene. The use of configurations such as side by side, core-sheath, segmented or islands in the sea means that the developed fibres can be given properties such as self crimp, micro/nanofibres or enables conductive or anti-bacterial fibres to be obtained.
Research to improve the mechanical and hydraulic properties as well as the durability of geotextiles in order to increase their capacities.
Development of fibres offering high tenacity and improved durability for applications in civil engineering projects.
Study of filtering operations, requirements and needs according to the end applications. Application of nanofibre veils for high-performance filters.
Lines of Innovation:
Determinaciones específicas sobre Geocompuestos. A destacar, por su carácter novedoso, la evaluación de la permeabilidad de geocompuestos bentoníticos en aplicaciones de vertedero.
Thermal insulation studies carried out on garments, under critical wind, temperature and moisture conditions.
AITEX evaluates the Fire Reaction rating of all kinds of textile and construction materials, in accordance with the European Standard UNE EN 13501-1:2007.
This European Standard establishes 7 ratings: A1, A2, B, C, D, E and F; which define the contribution of a material to a fire, with A1 being the best possible rating. These ratings are complemented with two additional parameters:
- Smoke opaqueness: s1 (low), s2 and s3 (high).
- Dripping or falling of alight particles: d0 (none), d1 and d2 (dangerous)
A material is classified depending on its final application.
“made in Green” is both a certificate and a label which, by controlling product traceability, ensures:
- The absence of substances that are harmful to HEALTH
- Respect for the ENVIRONMENT
- Respect for the HUMAN RIGHTS OF WORKERS
