Enhancing Fire Safety and Aesthetic Quality of Curtain Fabrics with Flame Retardant Adhesive — Zhejiang Ruico Advanced Materials

Curtain fabrics play a vital role in interior decoration by enhancing visual appeal, providing privacy, and improving light control. However, they also present one of the highest fire risks in indoor environments due to their extensive surface area and frequent use of synthetic materials such as polyester. To address this challenge, Zhejiang Ruico Advanced Materials has developed a new generation of flame retardant adhesives specifically designed for curtain fabric applications — combining safety, performance, and sustainability in one solution.

1. The Need for Flame Retardant Solutions in Curtain Fabrics

In commercial and public spaces such as hotels, theaters, hospitals, and offices, curtain materials must comply with stringent fire safety regulations like NFPA 701 (USA), BS 5867 (UK), and DIN 4102 (Germany). Traditional flame retardant treatments often rely on direct chemical impregnation or surface spraying, which can negatively affect the softness, color fastness, and mechanical strength of the fabric.

Flame retardant adhesives offer a more advanced approach — they act as a functional binder that securely integrates flame retardant components into the textile structure, forming a protective coating or lamination layer. This ensures long-lasting fire resistance while preserving the original texture and drape of the curtain fabric.

2. Ruico’s Advanced Adhesive Technology

Zhejiang Ruico Advanced Materials has developed water-based flame retardant adhesive systems using acrylic and polyurethane emulsion technology, optimized for textile bonding and coating. The adhesives are formulated with phosphorus-nitrogen synergistic flame retardant systems and intumescent additives, providing a balanced combination of flame resistance, flexibility, and durability.

When exposed to heat or flame, the adhesive undergoes an intumescent reaction, expanding to form a stable, insulating char layer. This layer blocks oxygen supply and heat transfer, effectively delaying ignition and preventing the spread of fire. Compared with conventional halogenated systems, Ruico’s halogen-free adhesives release low smoke and non-toxic gases, meeting environmental standards such as REACH and RoHS.

3. Performance and Application Advantages

Ruico’s flame retardant adhesive offers several performance advantages:

• Excellent flame retardancy: Fabrics treated with Ruico adhesives achieve superior fire performance, passing vertical burn and limiting oxygen index tests.

• Soft hand feel: The flexible polymer backbone ensures that the treated curtains maintain a natural drape and comfortable texture.

• Durability: The adhesive forms a strong bond with fibers, ensuring resistance to washing, dry cleaning, and UV exposure.

• Low VOC & environmental compliance: As a water-based system, the adhesive contains no formaldehyde, plasticizers, or heavy metals.

• Versatile processing: Suitable for coating, lamination, or impregnation on various substrates including polyester, cotton blends, and nonwovens.

The product’s balanced physical and chemical performance allows it to integrate smoothly into textile finishing lines without requiring major process modifications.

4. Applications in Modern Interior Textiles

Ruico’s flame retardant adhesive is widely used for manufacturing curtains, draperies, stage backdrops, and decorative textiles used in public buildings and transportation interiors. It provides excellent adhesion between flame retardant films, fabrics, and liners, ensuring a durable composite structure.

For decorative curtains, the adhesive can also be combined with pigments or printing layers, achieving both aesthetic and safety functions. Its transparent film formation makes it ideal for maintaining vivid colors and delicate fabric textures.

5. Sustainable and Safe Fire Protection

Zhejiang Ruico emphasizes sustainable development throughout its material innovation process. The flame retardant adhesives are free from halogens, PBDEs, and formaldehyde — minimizing environmental impact while ensuring occupant safety. The low-VOC formulation improves indoor air quality, a key concern in hotels, schools, and healthcare facilities.

Moreover, Ruico’s R&D team continuously works on improving flame retardant efficiency while reducing coating weight, helping manufacturers achieve lightweight, resource-efficient, and cost-effective textile products.

6. Conclusion

With rising global attention on fire safety and green manufacturing, Ruico’s flame retardant adhesive for curtain fabrics stands out as a forward-looking solution that blends advanced polymer technology, superior safety performance, and environmental responsibility.

By choosing Ruico’s products, fabric manufacturers can achieve a perfect balance between flame resistance, aesthetics, and sustainability, ensuring safer and more beautiful living and working environments.
