DTY microfilament is one of the products of the SIRANG CO-operative company
(The largest producer of various types of polyester and polypropylene threads)
Here you will get familiar about this type of fiber and its production process:

Polyester drawn textured yarn (DTY) microfilament

Compared to other textured yarns, DTY microfilament has a higher number of filaments and its filament measure is less than one Denier.

These filaments are finer than natural silk leading to the soft handle of the fabrics.


The small diameter of the micro filaments declined the flexural resistance of the yarn, hence incrementing the flexibility of the fabric leading to its proper hangability. Its excellent water absorption is another feature of this yarn that will cause appropriate colorability of the yarn and fabrics, resulting in proper sweat absorption.
