A typical manufactured polyester yarn filament is about 3 to 6 denier. While Micro Filament yarns have very fine filaments and the grade of each filament is less than one denier.
The presence of very fine fibers in the manufactured yarns has created extraordinary features such as the high flexibility of the yarns and the soft feel of the goods. The hanging ability of the fabric produced is excellent and they also have good thermal insulation properties.
Sirang company has made it possible to melt and produce microfilament POY thread in the range of 40-750 detex grade, and sometimes the grade of each filament reaches 0.5 denier.
