Abstract
A flat yarn wherein fibers composing a yarn are bonded to each other substantially in a side-by-side manner to form a tape-like flat body and the flat body has a plurality of gear-crimped portions across a width thereof. There may be a plurality of reverse points at which front and back surfaces of the yarn replace each other. The points are twisted in the same direction and positioned at random intervals from each other. The gear-crimped portions are arranged randomly in the lengthwise direction of the yarn. The fibers composing the yarn are bonded to each other in an intermittent manner in the lengthwise direction of the yarn. A fabric made from the flat yarn has an aesthetic appearance and soft touch as well as good crease resistance. A method of production for the same is also provided.
