The critical aspect of these molecules is that they are lengthy and versatile. This A part of the spandex fiber is chargeable for its stretching characteristic. Another pre-polymer applied to supply spandex is usually a polymeric di-isocyanate. This is a shorter chain polymer, which has an isocyanate (-NCO) team on both finishes. The principal attribute of this molecule is its rigidity. Within the fiber, this molecule gives power.
Double covered yarn encompasses a spandex Main that may be enveloped by two most important yarns twisted in reverse Instructions—one in the Z twist (clockwise) and the other within the S twist (counterclockwise). This twin-layer wrapping method not simply enhances the durability and elasticity of your yarn but additionally makes it possible for for various twist angles to generate various fabric hand feels.

Spandex Extrusion: Spandex is then extruded on to the core yarn. This process is performed in a heated surroundings in which the spandex is within a molten state, permitting it to adhere towards the core yarn.
2. During the chain extension reaction, the pre-polymer is reacted with an equivalent level of di-amine. It results in an answer which is diluted with a solvent to make the spinning Answer.
