Tricot is a warp knit characterized by vertical wales on one side, and horizontal zigzags on the other. While the vertical wales are technically on the face, either side may be the face of the fabric in use.
Originally silk, and now mostly made of manufactured filament fibers (nylon or polyester), tricot has some horizontal give, little vertical give. It will not ravel or run. The name comes from the French tricoter, “to knit.”
Uses: Light to heavy in weight, tricot is used for lingerie, day and evening wear
