Spandex can be used bare, with no processing before inclusion in the hosiery and Spandex fabrics. A simple Spandex thread is added (woven into) to the structure created by the main flat or textured thread. Another production technique is knitting bare or covered Spandex yarn within the garment. This is the vanisé or plated technique, where one yarn appears on the front and the other on the back of the back of the fabric.

It is generally used in alternate rows of knit yarn. Finally, the covered yarn can be used in every row - in every thread of the knit - for three dimensional stretch.

Covered Spandex is also used. The covering involves wrapping the Spandex in the main yarn in the nylon hosiery, so that the Spandex becomes the yarn core.  

Four processes can be used for covering:

Single covered: the nylon or other fibre is wrapped in a spiral around the Spandex once only with an average of 1,200-2,200 turns/metre. The more turns, the higher the quality.

Double covered: the Spandex yarn is wrapped in two layers of nylon or other fabric, one clockwise and the other anticlockwise. The average number of turns is 2,400 turns/metre, but this number can reach 3,000 per metre in ultra-high quality yarns. It is used in yarn intended for the production of high quality sheer tights.

Air covered: Spandex in tension and texturised nylon are passed together through a jet of air, interlacing the nylon at intervals to Spandex core.

Core-spun: during the yarning process the Spandex is covered with a coating of discontiunuous fibres.
