Spandex Yarn
The first elastomer fibre was patented in 1959 under the name Lycra, and commercialisation began in 1962. At first Lycra fibre was used in medical stockings, because the manufacturing process was initially limited to high count fabrics. But it was clear from the very start that elastomers offered incredible potential. In 1964 a famous Italian stylist presented a Spandex swimwear fabric.
In the 1970s research in this field concentrated on obtaining higher thread counts, but it wasn’t until the early 1980s that elastomers made their appearance in the legwear market, giving tights and stockings unprecedented comfort and fit.
Spandex Yarn Used
LYCRA is never used alone, but is always used in combination with one or more natural or synthetic fibers to give the fabric elasticity, maintaining its look and primary feel. It can be used in varying amounts depending on the type of fabric or application, considering that 2% is sufficient to improve the quality of the product and enhance dynamism, drape and shape recovery properties.
Spandex Yarn Properties
Spandex can be used bare and requires no processing prior to incorporation into 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 to weave naked or covered spandex yarns within garments. This is the vanisé or electroplating technique where one yarn appears on the front of the fabric and the other yarn appears on the back of the fabric.
Spandex Yarn characteristic
It is usually used for alternating rows of knitted yarn. Finally, covered yarn can be used for each row—each thread knitted—for three-dimensional stretching.
Covered spandex is also used. Covering involves wrapping spandex in the main yarn of the nylon stocking, making spandex the core of the yarn.
Four processes are available for coverage:
- Monolayer: Nylon or other fibers are wound around spandex only once, with an average of 1,200-2,200 turns/meter. The higher the number of revolutions, the higher the quality.
- Double Wrap: Spandex yarn is wrapped in two layers of nylon or other fabric, one clockwise and the other counterclockwise. The average number of turns is 2,400 turns/meter, but in ultra-high-quality yarns this number can reach 3,000 turns per meter. It is used in the production of yarns for high-quality sheer tights.
- Air Overlay: Tension spandex and textured nylon are air jetted together, interweaving the nylon to the spandex core at intervals.
- Core-spun yarn: During the yarn-forming process, the spandex is covered by a layer of discontinuous fibers.
