EcoCoat
The recycling of firmly bonded material systems is a major challenge. An example for this is the field of textile floor coverings, in which a wide variety of materials have to be combined to create different functionalities. The most common latex coating used to connect the materials hinders a high-quality recycling of the components polyamide, polyester and polypropylene after the use phase. The aim is therefore to develop a soluble bio-based coating system for textile floor coverings based on protein adhesion promoters and a degradable binder matrix based on pectin or lignin. In the development of the application and drying technology, particular importance is attached to industrial feasibility. During the use phase, the coating system should guarantee all necessary functions, and after use, it should be soluble by applying a trigger (e.g. extreme pH or temperature). The elaboration of a recycling concept including logistics, taking into account new business models for the products addressed here (e.g. leasing of the flooring), is an important basis for a sound and rapid transfer of the research results into practice. Main users of the research results are SMEs from the field of textile floor coverings, textile multi-material systems (home, automotive, technical textiles), coating, adhesives, biotechnology, represented in the PA by companies and associations.
