The virtually infinite relationship between length and diameter is a form factor that gives unique features to fibres that differentiates them both in terms of their physical and chemical properties and  adaptation to processes with high productive rates.

Fibres integrate a wide range of products of daily use, both in dispersed form and regularly oriented by textile processes. The potential for innovation at fibre level is broad with application in the most diverse activity sectors.

The Functional Fibres department aims the development, functionalization and production of unconventional fibres capable of performing specific functions in textile and non-textile structures with the ability to confer unique properties to products from several areas, such as medical area, clothing, composite materials, rope, civil construction, etc.

The development stages involved are: polymer formulation, spinning process and performance evaluation. Polymer compounding confers different properties to the materials, both by the addition of nanoparticles, and the combination of polymers and additives. The bi- or tri-component fibre production technology makes possible the combination of unique properties enabled either through the base polymer, the addition of specific compounds or the chemical finishing of the fibres.

Thus, it becomes possible to obtain devices in the form of fibre that change their characteristics by the action of external stimuli, such as light, pressure, among others.

Overall, functional fibres can be defined as a set of all components that go beyond aesthetics and decoration, allowing to obtain materials with innovative, efficient and intelligent features.

Its development represents the core of a technological progression that enables the industry to answer more easily to current and future market needs.
