Triobal polyester is a multiple filament, twisted, high-sheen continuous fiber thread. It has the bright appearance of rayon or silk, but the advantages of a polyester fiber. Triangular shaped fibers reflect more light and give an attractive sparkle to textiles. Triobal polyester threads are made by spinning or twisting together shorter lengths of polyester fibers. This thread gives the look of a cotton thread, but has more elasticity, therefore does not cut into quality quilt shop cotton fabric.
