product details
Introduce our products
Nonwoven insole board is a dense, high-performance structural substrate manufactured by needle-punching, thermo-bonding, and impregnating synthetic fiber matrices (primarily high-tenacity polyester and polypropylene fibers). Engineered to provide foundational torsional stability, structural integrity, and shape retention in medium-to-heavy footwear construction, this material delivers high stitch-tear strength ($\ge 65\text{ N}$), high flex cycle threshold ($\ge 100,000$ cycles without structural cracking), and superior moisture desorption. Solamni produces precision-calendered sheet goods and continuous roll options with strict thickness tolerance ($\pm 0.05\text{ mm}$) to optimize automated multi-ply die-cutting and welt-stitching operations.

Quality Control & Testing Standards
To eliminate midsole sagging, edge delamination, and moisture-induced softening in completed footwear, Solamni subjects every batch of nonwoven insole board to rigorous physical testing. Raw synthetic fibers are carded, needle-punched, and saturated with high-modulus latex binders before undergoing continuous multi-stage heated calendering to lock in density profile uniformity.

Every production run is monitored using automated thickness sensors across full sheet dimensions to ensure absolute alignment for automated die-stamping tools. In our internal laboratory, batch samples are subjected to:
- SATRA TM3 Flex Fatigue Testing: Tested beyond 100,000 continuous flex cycles under humid conditions to guarantee zero structural breaking or delamination along flex lines.
- Moisture Absorption & Desorption Cycles (SATRA TM31): Verified for rapid sweat absorption during wear and rapid drying without swelling or loss of stiffness during post-wear rest periods.
Industrial Application Scenarios
Solamni nonwoven insole boards are engineered for structural application across high-stress footwear categories:
Athletic & Performance Footwear
Formulated as lightweight, high-flexibility strobel insole boards and lasting boards providing structural stability under high impact and torsional forces.
Safety, Work & Military Boots
High-density $2.0\text{mm}-3.0\text{mm}$ boards engineered to accommodate steel or composite shanks, offering high puncture resistance and stitch-tear strength for Goodyear-welted and cement-constructed boots.
Casual & Dress Shoes
Calendered, smooth-finish insole boards providing shape retention, heel seat stability, and moisture management for men's and women's dress shoes.
