FEFC®dwr, a nylon 66 product developed by FEFC, is completely PFC-free. This eco-friendly product, which boasts durable, water-repelling and water-resistant qualities with a fine texture, is currently being produced in partnership with multiple internationally renowned sports brands and seeing growth in popularity on the market.

Through material modification and production optimization, FEFC®dwr has achieved a water-proofing effect rivaling that of fabrics containing PFC and outperforming its counterparts in washability and durability. It has been used in a broad range of textile products, such as apparel for yoga, jogging and outdoor sports, as well as down jackets, women's underwear and high-end fashion. The polo shirt FEFC co-developed with Lululemon using FEFC®dwr has been introduced to the market in 2024, and additional collaborations with brand customers are underway. FEFC®dwr allows the downstream customers to bypass the use of water repellents, a practice that reduces energy and resource consumption. Meanwhile, as a PFC-free product, FEFC®dwr is protecting the environment from negative impacts.
