Manufacture of polyolefin fishing line

A process for making lines with monofilament characteristics from filaments made of gel spun polyolefins, said process comprising the steps of:

• twisting a plurality of yarns made from a gel spun polyolefin filaments into a line with a neutral net twist;
• exposing said line to a temperature within the range from about 150.degree. C. to about 155.degree. C. for a time sufficient to fuse at least a portion of adjacent filaments into a fishing line having end fraying characteristics similar to conventional monofilaments.

A process for making a fishing line by the step comprising:

• heating a yarn made with at least two gel spun polyolefin filaments exhibiting a molecular weight of at least 400,000 and that have been coated with a coating material that enhances fusion between said at least two said filaments to a temperature within the melting point range of said filaments for a time sufficient to soften and fuse surfaces of adjacent filaments whereby fused surfaces secure individual filaments together within said yarn.
