Conclusions
Diphosphonite introduced into fibre wastes from the manufacture of polypropylene fibre has a multifunctional action:
-
it improves pigment dispersion;
-
it raises the light resistance of cord fibre and stability of properties in processing and storage;
-
it improves the service properties of carpet articles: strength, bulk elasticity, and resistance to abrasion.
