Danish producer Trevira Neckelmann has signed an agreement with the Fabelta Ninove group in Belgium to work together on the development and production of new generation polypropylene yarns which will be marketed under the trade name PP-TEX. "Our aim is to supply texturised polypropylene yarns which offer the user a high degree of light fasteness, durability, low weight and recyclability," says Trevira Neckelmann.
