For key sectors of the textile industry in Germany (sports, interior and automotive textiles), established, petroleum-based benchmark products made from polyethylene terephthalate (PET), or recycled PET were successfully recreated in the BioBase project using the biopolymers PA 4.10, PA 5.10, PA 10.10 and PA 12. The textile value chain was successfully traversed from the polymer to the textile surface. With the aim of developing bio-based alternatives from already available resources for textile applications and properties, the BioBase project takes up the vision of the BIOTEXFUTURE innovation area - the conversion of the textile value chain from petroleum-based to bio-based. The BioBase project was funded as part of the ‘National Research Strategy BioEconomy 2030’ in the BIOTEXFUTURE innovation space. An overview of the project results can be found in the sample catalogue, which is available for download on the project homepage.(https://biotexfuture.info/wp-content/uploads/2024/07/Musterkatalog-Biobase.pdf)

For this purpose, innovative bicomponent yarns with a core made of conventional polyamide 6 and a shell made of phosphorus-modified polyamide 6 were developed. The tufted textile floor coverings could be bonded using a hot melt adhesive, so that the wear layer and backing could be separated after usage. Based on the results of the Radiant Panel fire tests, the floor coverings developed in this way were able to achieve a fire class (Bfl-s1) suitable for official buildings. Two demonstrators were tested in a practical section and after three months of use, no change in appearance or delamination of the back could be detected. The wear layer and the backing were successfully separated using a hot calender.

Innovative helix yarns with a metal core and a corresponding acoustomechanical cleaning process were developed.
The helix yarns consist of a metal core surrounded by carpet yarns in a two-stage, counter-rotating reversing direction. In addition, a new type of pile fixation and backing coating was developed.
Suitable process control was determined for acoustomechanical cleaning. The helix yarn structure with metal yarn has a positive effect on the cleaning effect.
The findings were scaled up to a functional model and improvement approaches were formulated. The potential for a doubling of surface area performance and a significant reduction in the use of cleaning agents and water was identified.

What influence do yarns have on the acoustic effectiveness of textile surfaces in a room? How to test the acoustic effectiveness of yarns? Is it possible to specifically influence the acoustic effectiveness through the yarn construction?

The “Acoustic Yarns” project is addressing these and other exciting issues. Further insights can be found on the project homepage.
