Yuhzimu Defining High-Quality Nonwoven Carpet Primary Backing

What is Yuhzimu? The BICO Technology

Yuhzimu is not a standard spunbond or needle-punched nonwoven. Its superiority lies in its unique patented manufacturing process that produces a BICO (BICOmponent) nonwoven fabric.

• The filaments themselves are engineered as bicomponent fibers, typically with a core-sheath structure:
• The core is usually made of a strong, resilient polymer like polyester, providing the backbone and dimensional stability.
• The outer sheath is made of a lower-melting-point polymer, most often polyamide (nylon).

This ingenious construction is the source of Yuzhimu's exceptional properties. During production, heat is applied, causing the nylon sheath to soften and melt slightly. As the web of filaments cools, the sheaths bond firmly to one another at each filament intersection. This creates a monolithic, thermally bonded fabric that is incredibly strong and uniform.

Yuzhimu carpet primary backing features:

1. Tuft stabilization: Securing yarns during tufting and preventing fiber slippage, with superior stitch lock for sharp pattern definition ​
2. Dimensional stability: Resisting contraction, expansion, or curling under temperature/humidity fluctuations ​
3. Performance enhancement: Imparting tear resistance, noise reduction, and durability, especially in high-traffic areas

Yuzhimu carpet primary backing advantages:

1. Unmatched Dimensional Stability

The dense, thermally bonded matrix of filaments resists stretching and shrinking far better than many alternative backings. This ensures that carpets made with Yuzhimu lie flat, resist buckling, and maintain their fit over time, even under heavy rolling loads in commercial settings. This is a critical factor in preventing costly installation failures.

2. Superior Tuft Bind (Pull-out Strength)

This is arguably Yuzhimu's most celebrated feature. The thermally bonded web creates a dense, fibrous, and highly textured surface. When the latex adhesive is applied during the lamination of the secondary backing, it penetrates deep into this complex structure, mechanically locking the yarn tufts in place. The result is an exceptionally high tuft bind, meaning the carpet pile is extremely resistant to being pulled out, which is a key indicator of long-term durability.

3. Excellent Puncture Resistance and Tuffing Performance

Yuzhimu's robust structure provides a consistent and durable surface for high-speed tufting needles. It resists tearing and puncturing during the manufacturing process, allowing for clean tuft formation and high production speeds with minimal downtime. Its consistency eliminates the risk of defects like "grinning" (where the backing becomes visible between tufts).
