The same technique used for making twine is also used to make thread, which is thinner, yarn, and rope, which is stronger and thicker, generally with three or more strands. Natural fibres used for making twine include wool, cotton, sisal, jute, hemp, henequen, paper, and coir. A variety of synthetic fibres are also used. Twine is a popular ...

Twine is a light string or strong thread composed of two or more smaller strands or yarns twisted, and then twisted together. More generally, the term can be applied to a cord. Natural fibres used for making twine include cotton, sisal, jute, hemp, henequen, and coir. A variety of synthetic fibres are also used.
In the absence of the metal ion, the same organic reactants produce different products. The term is mainly used in coordination chemistry. The template effects emphasizes the pre-organization provided by the coordination sphere, although the coordination modifies the electronic properties (acidity, electrophilicity, etc.) of ligands.

Synthetic baling twine tied around bales of hay. Baling twine or baler twine is a small diameter sisal or synthetic twine used to bind a quantity of fibrous material (notably hay or straw) into a more compact and easily-stacked form. [citation needed] Tensile strengths of single-ply baling twine range from 95 psi (0.66 MPa) to 325 psi (2.24 MPa ...
