Spandex covered yarn, also called lycra spandex yarn or elastic covered yarn, is a novel type of textile substance that combines the elasticity of spandex yarn (generally known as elastane or Lycra) with the power and texture of other Main yarn components( a hundred% polyester or one hundred% nylon).
A substandard or 2nd-quality spandex yarn might be run correctly into a yarn covering software. This process will typically go over the imperfection of your denier variation in the elastomeric yarn.
The final developments in the fibers have been worked out independently by scientists at Du Pont and also the U.S. Rubber Company. Du Pont utilized the brand identify Lycra and started whole scale manufacture in 1962. These are at this time the globe leader inside the production of spandex fibers.

The core spandex is covered to a superb extent plus the Main exposure is much less, and because the outer wrapped filaments are wrapped with reverse spiral angles symmetrically round the Main filaments, the elasticity of your wrapped yarn is well balanced and may typically be processed from the afterwards process without shaping procedure, but the processing cost of double wrapped yarn is higher.
