Line is made of either natural or synthetic fibers twisted into yarns and grouped together to form strands. To form the line, the strands are twisted, plaited or braided together to form the final product.
How the lines are twisted together determines its "lay." Line can be right or left lay, and it is usually plain laid, plaited or double braided depending upon the intended use of the line.
Plain laid line is made of three strands twisted to the left or the right, but the most plain laid lines are right laid. Plain laid lines are also called "three strand" line.
Plaited line is made of eight strands. Four strands are twisted to the left and four to the right which are then paired and worked like a four strand braid.
Braided line is usually made from three strands braided together and comes in different construction types such as hollow-braided, stuffer-braided, solid-braided and double braided. The most common type of braided line is double braided nylon.
The construction of the line, along with the material used to make the line, determines the strength of the line and its various uses.
