Extensive consumer research shows freshness to be a high priority benefit for apparel segments, among men and women worldwide. XTRA-FRESH nylon fibers prevent bacterial growth, a major cause of body odor by using an Antimicrobial Masterbatch based on silver ions. Using the natural properties of silver, it is designed to provide permanent freshness and it is safe for humans and for the environment.


It prevents bacteria from colonizing the fabric without harming natural bacteria on the skin. Its activity is limited to the surface of the textile, keeping it free from bacteria and thus free from odors.

The additives are introduced during melt spinning process, which provides a strong resistance during all processes and allows a homogeneous incorporation of the silver additive into the polymer matrix and so, along the yarn.
