This exclusive elastic home of your spandex fibers is a immediate results of the material’s chemical composition. The fibers are made up of various polymer strands. These strands are made up of two types of segments: extended, amorphous segments and quick, rigid segments. Of their normal state, the amorphous segments Have a very random molecular structure. They intermingle and make the fibers comfortable. A few of the rigid portions of the polymers bond with each other and provides the fiber construction. Every time a force is applied to extend the fibers, the bonds in between the rigid sections are damaged, and also the amorphous segments straighten out.
As the answer passes with the spinneret, it transforms into fibers. Prior to solidification, these fibers are subjected to a heated nitrogen and solvent gasoline mix.

Spandex Extrusion: Spandex is then extruded onto the core yarn. This process is completed in the heated natural environment where by the spandex is in a molten state, permitting it to adhere to the Main yarn.
ACY combines filaments with a sequential compressed air click here jet and covers the internal elastic with air dots. SCY and DCY are made by mechanically wrapping the elastic Main with one or two outer filaments.
3. The Main yarn of Main spun yarn is wrapped outdoors because of the staple fibre, you can’t see the corn yarn with a very well-wrapped Main spun yarn.
When they are initially generated, spandex fibers are white. For that reason, colorants are extra to further improve their aesthetic look. Dispersed and acid dyes are typically employed. In the event the spandex fibers are interwoven with other fibers for example nylon or polyester, Specific dying approaches are essential.
