Abstract
The improved multifilament structure is a low denier, heat treated multifilament structure that provides for advantageous mechanical properties, including fray resistance, low shrinkage, high tensile strength and low elongation.
Claims17
The method of creating a fray resistant multi-filament structure comprising the steps of:
- Providing a multi-filament structure, the multi-filament structure comprising at least one yarn, the at least one yarn includes a plurality of filaments, each the plurality of filaments comprising a material;
- Twisting the plurality of filaments into a twists-per-inch to create a twisted multi-filament structure wherein the twists-per-inch (TPI) comprises a range of 20 TPI to 60 TPI;
- and
- Drawing the twisted multi-filament structure at a drawing temperature to bind a portion of the plurality of filaments to each other to create one or more unions along the length of the twisted multi-filament structure to form the fray resistant multi-filament structure.
