RESEARCH INTO THE PROCESS OF CREATING BIO-BASED PU COATINGS FOR APPLICATION IN THE TEXTILE SECTOR
BIOCOATEX
Motivations
In recent decades, over-reliance on petrochemicals has led to irreversible environmental pollution problems. In addition, their high cost and carbon-emissions trading have led to the partial or complete substitution of petrochemicals by solutions using renewable biomass processing.
In the textile sector, significant progress has been made in eco-design and the circular economy. Within the broad spectrum of existing eco-design tools, the use of bio-based or biodegradable materials is a proising option. Thus, the development and implementation of new biofibres, natural dyes and biopolymers and bioadhesives is a growing field of research.
This R&D project will address the development of sustainable leather-like solutions derived from the use of low environmental-impact polyurethane coatings.

Objectives
Development of sustainable polyurethane systems for textile coatings and to this end, specific lines of work will be addressed:
- Study of the formulation and application of partially bio-based polyurethane resins, derived from the partial or total substitution of petrochemical polyols present in the formulation by compounds derived from vegetable oils (e.g. castor oil, palm oil and limonene).
- Study of the formulation and application of polyurethane resins with biocidal characteristics derived from the use of active principles of plant origin.
- Study of the implementation of dyes of natural origin in the development of coloured bio-based resins and the validation of their fastness against different physical and/or chemical agents.
- Study of implementing micro-cellulose or other fillers of vegetable origin as an alternative to the mineral fillers (e.g. calcium carbonate) usually used to reduce the cost of formulations and to obtain better mechanical abrasion resistance.
Expected results

-
Synthesis of new polyurethane dispersions with a high content of renewable raw materials.
-
Laboratory scale applicability study of synthesised resins in textile coating processes.
-
Physico-mechanical and functional characterisation of the new sustainable polyurethane formulations developed and of the resulting simile-leather prototypes.
-
Preliminary environmental impact study to calculate the product’s carbon footprint.
-
Generation of scientific-technical knowledge for transfer to companies in the textile, chemical and biotechnological sectors.
