Microban International launches PFAS-free water-resistant textile technology

Microban International, globally recognized for its leadership in antimicrobial and odor control technologies, has unveiled a groundbreaking portfolio of PFAS- and PFOS-free water-resistant textile finishes. Branded as H₂O Shield, this new line marks Microban’s strategic expansion into water-resistant solutions and underscores its commitment to environmentally responsible innovation.

As global scrutiny of per- and polyfluoroalkyl substances (PFAS) intensifies, Microban’s H₂O Shield offers a timely and vital alternative. PFAS, including PFOS, are widely used synthetic chemicals known for their environmental persistence and potential health risks. In response to growing consumer demand and regulatory pressure, brands across industries are increasingly seeking PFAS-free alternatives. Microban’s new technology is designed to meet this need without compromising performance.

A Tailored Portfolio for Diverse Textile Needs

The H₂O Shield portfolio features four distinct water-repellent formulations, each engineered to address specific performance requirements and aesthetic challenges across a wide range of textile applications:

• WR1000: Ideal for general water repellency in low-contact applications such as shower curtains, tents, and awnings.
• WR1001: Optimized for moisture-wicking and sweat resistance, targeting high-performance apparel like running gear, ski jackets, and workout clothing.
• WR1002: Specifically formulated to reduce chalking and color shifts on dark fabrics prone to wear, such as outdoor gear and gloves.
• WR1003: Enhances tear resistance and reduces seam slippage, making it ideal for rugged applications like backpacks and heavy-duty tents.

To further enhance adaptability, Microban offers WR-P, an optional pretreatment that extends compatibility to challenging fabrics. WR-P allows manufacturers to reduce the required dosage of water-repellent agents by 15–20% while improving wash durability—a critical factor in long-term textile performance.

Proven Performance, Sustainable Solution

The H₂O Shield technology delivers exceptional water resistance, consistently achieving ratings of 80 or higher on the AATCC TM22 spray repellency test. Equally notable is the finish’s durability through 20+ home launderings, ensuring extended protection without environmental trade-offs.

Importantly, the finishes are applied using standard wet processing techniques, such as pad baths and exhaust cycles, making the transition seamless for textile manufacturers and brands already equipped with conventional finishing infrastructure.

Integrated Functionality and Brand Support

In a move that further distinguishes the H₂O Shield portfolio, Microban has designed the finishes to integrate effortlessly with its existing antimicrobial and odor control technologies. This integrated approach enables manufacturers to deliver multi-functional textiles that meet evolving consumer expectations for sustainability, hygiene, and performance.

Microban provides a unique turnkey support structure, assisting our partners in combining finishing technologies while ensuring compliance and compatibility. Partners can also leverage our technical and testing support and trusted brand names. This synergy allows brands to deliver multi-functional performance with tailored solutions, protecting and extending the overall life of textile goods and delivering what consumers desire.
