Textile polymers and raw materials

Search line summary


The properties of natural and chemical fibres for textile application are studied. These properties refer to its microstructure and this is related to its physical, mechanical, thermal, chemical and sorption properties.

The most important have been the works relating to wool, cotton, viscous and other artificial and polyester fibres, polyamide, acrylic and polylactide as the most studied among synthetic fibres.

The change of microstructure and fibres properties has been studied with all the variables of their processing.

New techniques are also being developed for characterizing and adapting techniques already used with other fibres for the new fibrous polymers, mainly from new sources of natural fibres. Its suitability is studied and the appropriate treatments are made for its treatment in spinning, weaving, dyeing and finishing and also in the processes of non-woven textile structures.

The objective in this case is to achieve the prototypes design from new materials and characterize their properties in order to find new sources of raw materials for commercial application.

The functionalization of conventional and new technology materials, with various techniques, to obtain new properties is also studied (see the corresponding line of research).
