Toray Industries, Inc. announced that using a proprietary composite spinning technology called NANODESIGN®, Toray Industries has created a new nylon textile, one that delivers high water repellency despite using a DWR treatment with a lower environmental cost.
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 two benefits:
- The construction enables the textile to use C6 water repellents, which are normally insufficient for outdoor sports and
- 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.
Fluorine-based water repellents used in the past do not easily decompose naturally because of its stable chemical structure. It also contains Perfluorooctanoic Acid (PFOA), (also known as C8), which could accumulate in the human body and remain in the natural environment. 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.
Toray plans to market the textile in fall 2020, as a material variation of the existing textile brands Airtastic®, ENTRANT® and Dermizax®. Leveraging the textile’s high water repellant properties, Toray will target the active outdoor sports and skiing markets, as well as athleisure.
In North America, Toray International America Inc. will provide the new textile.
