XLA is high-tech elastic fiber made of cross linked, denaturized polyolefin raw materials which is very chemical stable. Its molecular microstructure, mainly by “C-C” and “C-H” single bonds, is as firm as that of hexahedral diamond carbon. It can withstand strong acid and alkali corrosion at room temperature for long time without being damaged. XLA is remarkable strong and stable, not easy to age or break as spandex does.
Performance advantage of XLA comes from its special molecular structure, not from additional post-processing. Because the advantage is innate characteristics of XLA, it is durable and stable. Therefore, XLA can withstand strong wool double mercerizing process to produce the woolen sweater feel like cashmere.
