PROTEX

Research and digitization of processes for obtaining eco-sustainable coatings for textiles.

 

CONSORTIUM:

  • ENSO
  • CETIM

 

OBJECTIVE:

PROTEX main objective is focused on obtaining new eco-sustainable coatings based on cellulose micro/nanofibers with antimicrobial, antiviral and/or hydrophobic functionalities for their application in textiles, mainly in sanitary and protective textiles. All this, under the premise of a digitalized process that allows online control of the quality of each stage developed to obtain the new bio-based coatings, as well as to study the implementation of the process at industrial level.

2021 ANNUITY PROGRESS:
During this year, CETIM has conducted a bibliographic search for the design of a system to obtain in-situ measurements of the parameters that are indicative of the quality of nanofibers. Afterwards, photonic equipment was selected for the construction of a test bench to carry out the first experiments with the selected parameters (viscosity and transmittance). Finally, the 3D modeling of the Digital Twin of the complete process was carried out, starting the work of parameterization of the same.

 

2022 ANNUITY PROGRESS:
In the second milestone, after having validated the photonic technologies in experimental laboratory set-up, CETIM has developed an integrated measurement system with light source, detector, optical fiber and external coating with high temperature 3D printing, creating a probe suitable for use in the continuous process. On the other hand, a customized software for remote control of energy consumption has been developed. As far as the Digital Twin is concerned, the parameterization started in 2021 has been completed and the export of data to a cloud platform has been designed to ensure access by users.

 

2023 ANNUITY PROGRESS:
During the PROTEX Project 2023 annuity, sensor system has been optimised with the transmittance probe miniaturisation thanks to integration of lighter, more resistant and easier to handle fibre optics. We have worked to improve automatic data acquisition and the website was created to make data more accessible to employees. In the coating study task, different characterisation techniques have been tested to better adapt to the coatings control at different stages. As for digital twins and predictive algorithms use, in this last year, efforts were focused on data analysis to reduce the number of steps in the homogeniser, which is the most electricity-consuming element of the process.

 

 

 

FUNDING:
This project is funded by the Agencia Gallega de Innovación under the 2021 call of the CONECTA COVID grant program. The grants awarded under this program have been funded by the Fondo Europeo de Desarrollo Regional (FEDER) under the FEDER Galicia 2014-2020 operational program as part of the Union’s response to the COVID-19 pandemic. The project is supported by the Vicepresidencia Primera y Consellería de Economía, Industria e Innovación.
