There is disclosed a process for making fibrous material which is particularly suitable for the manufacture of baler twine. The material is preferably made from polypropylene and is produced from film which is roll-embossed and fibrillated, the roll-embossing temperature being substantially lower than the conventional roll-embossing temperature. In the case of polypropylene film this is within the range 60.degree. C to 90.degree. C, preferably about 80.degree. C. As a result, the fibrous material has a high proportion of clusters of from 2 to 5 unseparated incipient filaments. Baler twine made from the material is economical to produce and has improved physical characteristics especially good strength combined with good knot retention ability.
