A spiral or corkscrew yarn is a plied yarn that displays a characteristic smooth spiraling of one component around other. Following figure shows the basic structure, which is straightforward, and except in the differing lengths of the two yarns involved, very similar to the structure of marl yarn. Indeed, just like marl yarn shown also in the following Figure, it can be produced relatively simply on a double frame or under the ring spinning system. It is more textural in appearance than marl, and the finer counts may also appear in some of the laces used in lingerie.
