From the Sector

NC State University is a core partner in the BRIDGES Engine initiative backed by the US National Science Foundation, with up to $160 million available over ten years. A central focus is the development of miscanthus and switchgrass as feedstocks for biobased products.

The plant fibres are intended for applications including automotive, construction and packaging. NC State will contribute techno-economic assessment, sustainability analysis and processing expertise to convert agricultural feedstocks into fibre materials suitable for industrial use.

For technical textiles, the initiative is particularly relevant because it goes beyond laboratory-scale material development and aims to build supply chains, processing capacity and regional markets in parallel.

Avient is introducing Dyneema SK80, a new HMPE fibre grade for mooring lines and offshore applications. According to the company, the fibre was engineered at polymer level to deliver at least twice the durability and fatigue resistance of Dyneema SK78 in demanding mooring applications.

The technological emphasis is therefore less on headline tensile strength than on service life under cyclic loading. In mooring systems, repeated load cycles, abrasion, bending stress and environmental exposure are major failure drivers. Improved fatigue resistance can therefore have a direct effect on maintenance intervals, operational safety and lifecycle costs.

The new fibre will be presented at SMM in Hamburg in early September. For Textination, the development is relevant because high-performance fibres are increasingly being positioned not only through weight and strength advantages, but through durability, reliability and the total cost of technical textile systems.
