The project has completed Action 1 where data from textile companies wastes was recapitulated. Now we are working on action 2in the application of the wet laid technologie for using textile wastes in developing non wovens and also Action 3 using the non wovens produced to develop composites with good isolation properties.

During the first year of the project a summary of the current state of the most representative companies in the textile subsectors related to the revaluation of waste was compiled. Visits were carried out to selected spinning and weaving companies, and a questionnaire with relevant information relating to the management of solid waste was completed after each visit. This gave an overall picture of the current situation regarding the revaluation of textile waste solids, as well as enabling a classification of solid textile waste on a by-business basis to be created to help determine solid textile-waste generation by textile companies within the surveyed group.

Once the stage was completed the definition, selection and characterisation of the properties of textile waste was undertaken. Characterisation tests include morphological and chemical determination by employing standard analytical methods, for example, optical and electron microscopy, FT-IR, GC-MS, LC-MS. After the characterisation was complete, specific textile waste was selected to be used in a wet-laid process in order to obtain reinforcements for composites.

Afterwards, we have performed a definition, selection and characterization of the properties of the textile solid wastes. The characterization tests comprises morphologic and chemical determination through the employment of standar analytic methodologies, for example opticla microscopy and electrons,  FT-IR, GC-MS, LC-MS, etc. After the characterization, we have selected the especific textile wastes to be applied in the wet-laid process with the aim to obtain composites reinforcements.

During the second year, we have worked in the application of wet-laid for obtaining textile reinforcement applicable in the composites sector, considering the waste fibers as useful raw material and using them as reinforcement fibres in composite materials.

Before the production of composite materials, characterization tests have been performed, i.e. microscopy and mechanical properties studies, determination of the moisture absorption capacity…We have obtained three non-woven structures produced in a semi-industrial way derived from solid textile wastes that could be applied as reinforcement of composite materials.

We also studied the selection of polymeric matrix materials and additives for the LFT-D process and also we have already made some pilot tests with non-wovens. We have selected, as well, materials for the core and matrix for the sandwich technique and we have produced some samples that have been characterized regarding its behavior against fire and the acoustic isolation properties.

We have also organized a networking event in Valencia where 14 LIFE projects were presented and also the final dissemination and networking event that took place on the 18th October in the K Düsseldorf fair.
