Ratio of your part elements is answerable for providing distinct traits to the fibers. Therefore the ratio is strictly managed. The perfect ratio of glycol to di-isocyanate could be 1:two.

Perform rigorous high quality Management and inspections through the production process to make sure items meet up with specification necessities.

Pre-polymer is then reacted further more, in many different strategies, and drawn out to make a protracted fiber. The most often made use of process is the answer dry spinning that makes in excess of 90% of the planet’s spandex fibers.

Compatibility: When Mixing with other fibers, the chemical compatibility involving spandex and the opposite fibers is very important to guarantee the general security of The material.

2. Within the chain extension reaction, the pre-polymer is reacted with an equivalent degree of di-amine. It results in a solution that is diluted with a solvent to supply the spinning Resolution.
