<p>An improved synthetic twine and method of manufacturing same are disclosed. The synthetic twine comprises at least one longitudinally extending oriented synthetic ribbon which has been fibrillated to provide a net-like structure having fine fibril stems connected by finer fibril branches, and a synthetic binder in thin band form made of a material compatible with the synthetic ribbon. The synthetic binder is spirally wrapped around and fused to the synthetic ribbon. The method of making a twine comprises the steps of providing at least one longitudinally extending ribbon, orienting the synthetic ribbon and fibrillating the synthetic ribbon to provide a net-like structure having fine fibril stems connected by finer fibril branches. Thereafter, a synthetic binder in thin bank form is spirally wrapped and fused around the synthetic ribbon which has been oriented and fibrillated. Such a twine is more economical to produce, yet exhibits comparable characteristics to conventional synthetic twines, particularly in terms of knotting strength.</p> |
