TECHNICAL TEXTILE DYES AND FINISHES FROM THE VALORISATION OF NATURAL MATERIALS AND WASTES
APRONATEX 2
Motivation
In order to address the challenges faced by the textile sector and the consequences of its activity, the aim is to develop a legal framework that focuses on preventing the generation of wastewater and promoting the use of increasingly eco-sustainable reagents and compounds.
Environmental policies are becoming more restrictive regarding water usage. Along with the intent to protect the planet, there is a growing emphasis on ensuring that the reagents used in dyeing processes are less toxic to humans. This fosters innovation in sustainable textile dyeing and finishing processes using natural technical materials or waste, thereby enhancing the competitiveness of Spanish textile companies.
Objectives
- Improve extraction, dyeing, printing and pre-treatment processes for finishing with natural dyes.
- Research biotechnological processes to create new pigments/actives for textile applications.
- Research into the use of waste for textile finishing.
Value and competitive advantage
-
Use of natural and bio-based pigments that offer more sustainable solutions.
-
Extraction and dyeing processes with natural materials.
-
Bio-based alternatives to replace synthetic auxiliaries.
Obtained results
-
Development of formulas with natural pigments that have good lightfastness and intense colors.
-
Comparison of abrasion and washing fastness between bio-based and non-bio-based pastes, showing equivalent results.
-
Implementation of semi-industrial extraction and dyeing processes with natural materials, resulting in prototype garments.
-
Identification of over 50 bio-based alternatives to replace synthetic auxiliaries in various textile processes.
-
Development of water-repellent finishes with low PFAS content, achieving fabrics with less than 100 ppm total fluorine.
-
Dyeing with natural dyes in a jigger machine reduces GHG emissions and energy consumption by up to 30% compared to reactive dyes.
