SmartBioFinish

Development of a textile finishing technology based on anchor peptides for water- and oil-repellent properties

Motivation

In the BIOTEXFUTURE innovation space, new bio-based textiles are being developed to transform textile value chains. To produce 100% biobased functional textiles, it is necessary to develop biofibres and biobased finishes. Especially in the area of hydrophobic and oleophobic properties, it is necessary to use bio-based materials to replace the currently used finishes based on per- and polyfluorinated alkyl compounds (PFAS). This is of great importance in view of the recent EU regulation (possible ban on around ten thousand PFAS due to their toxicity and harmfulness to the environment and health) health.

Aim

The aim of the SmartBioFinish project is to substitute PFAS in textile applications by developing 100% bio-based water and oil repellent finishes based on anchor peptides. The functionality of the water/oil-repellent finishes will be validated and demonstrated in two different applications: sports textiles and personal protective equipment (PPE).

APPROACH

The project will be conducted iteratively and in four main development steps, which include the development of the anchor peptide-based hydrophobic and oleophobic agents, the development and optimisation of the finishing formulations, the development of the finishing process technology, and the demonstration of the functional properties in relevant industrial applications.

At DWI – Leibniz Institute for Interactive Materials the development of the anchor peptide-based hydrophobic and oleophobic finishes takes place. Anchor peptides and bio-compounds will be tested regarding their water and oil repellence properties.

Using the above agents as base material, the finishing formulations and the finishing process technology will be developed and the optimised finishing formulations and an industrially viable finishing process technology will be developed by the Institute of Textile Technology (ITA). SCHÜLER & CO. K.G. will scale up the finishing process technologies developed by ITA for the end applications on the selected textile materials. Subsequently, the demonstrators are developed by adidas and Ibena, thus evaluating their technical and economical performance.
