New polyamide textile

13.06.2019 A new polyamide textile that delivers high water repellency despite using a DWR treatment with a lower environmental cost has been created by the fiber and textile manufacturer Toray Industries Inc., Tokyo /Japan.

For this purpose, a proprietary composite spinning technology called Nanodesign is being used.
The textile’s structure has microscopic slits running lengthwise on the yarn. Water repelling treatments fill these slits below the outside diameter of the yarn, also making the treatment more abrasion-resistant. This results in 2 benefits:
-    the construction enables the textile to use C6 water repellents, which are normally insufficient for outdoor sports
-    the textile provides more resistance to abrasion, which is a leading contributor to diminishing DWR performance.
Despite the slits, the textile has the strength and abrasion-resistance of other yarns and is processed the same way.
Recent years have witnessed increasing environmental consciousness and there are growing needs for materials using water repellents with low environmental burden such as C6 water repellents do not contain PFOA.
