Herng Fa's system is especially noteworthy for its overall flexibility, as being the matching yarn and The 2 key yarns is often modified In keeping with particular client specifications.

Cooling and Location: After extrusion, the yarn is cooled to established the spandex layer. This action is very important for protecting the elasticity of your spandex.

Covered spandex yarn is actually a composite yarn that contains a spandex core wrapped with a number of levels of masking fibers.

Spandex can be a polymer; its macromolecular composition is designed up of repeating models (mars) denoted because of the x and n next to the parentheses during the construction. Each Spandex fiber will differ somewhat in size and composition based on the correct worth of x and n.

We don't sell, trade, or or else transfer to outside functions your Individually identifiable information and facts.

The essential function of these molecules is that they are long and versatile. This Element of the spandex fiber is responsible for its stretching attribute. One other pre-polymer utilised to create spandex can be a polymeric di-isocyanate. It is a shorter chain polymer, which has an isocyanate (-NCO) team on both of those finishes. The principal characteristic of this molecule is its rigidity. Within the fiber, this molecule offers strength.

Undergarments: Spandex is frequently used in the manufacture of undergarments, including bras, panties, and shapewear.
