At Leedings, transparency and innovation drive our mission to deliver high-performance PET acoustic panels and polyester acoustic panels that redefine sustainability and quality. In this second installment of our Q&A series, we delve deeper into production processes, material calculations, and long-term durability—answering the technical questions architects, designers, and eco-conscious clients frequently ask.
Q5: How much chemical fiber can be produced from one PET bottle?
Recycling efficiency is central to our eco-friendly ethos. Here’s the breakdown:
A standard 13g PET bottle yields 10g of chemical fiber.
A larger 18g bottle produces 14.11g of fiber.
Calculation Formula:
Fiber Output = Bottle Weight (g) × 0.8 (material recovery rate) × 0.98 (processing loss)
This means 80-85% of each bottle is repurposed into acoustic panel fibers, minimizing waste while maximizing resource efficiency.
Why It Matters:
By transforming discarded bottles into sound-absorbing solutions, Leedings reduces plastic pollution and supports circular economies—one panel at a time.
Q6: Single-Sided vs. Double-Sided Ironing: What’s the Difference?
Production Process & Principles
Single-Sided Ironing: Only one surface is heat-pressed, creating a smooth finish on the front while leaving the back unrefined.
Double-Sided Ironing: Panels are initially thickened to ≥2mm, then compressed by 2mm during final hot pressing. This enhances flatness on both sides but introduces unique challenges.
Why Double-Sided Panels May Show “Scratches”:
During needling (a process that binds fibers), only the front side is trimmed, leaving the reverse slightly textured. While this may resemble scratches visually, the surface remains smooth to the touch.
Variations in raw material shrinkage rates can amplify this effect, but Leedings’ precision controls ensure minimal aesthetic impact.
Key Takeaway: Double-sided ironing prioritizes structural uniformity, ideal for applications where both sides of the panel are visible (e.g., freestanding partitions).
Q7: How Much Fiber Is Used Per Production Batch?
Leedings’ manufacturing process balances efficiency and quality:
Input: 120kg of fiber per machine load.
Output: 107kg of finished panels after three sequential loads.
Why This Ratio?
The three-stage loading ensures consistent fiber distribution and optimal panel density, critical for achieving uniform acoustic performance.
Q8: Will Polyester Panels Degrade Over Time? What Are the Size Tolerances?
Long-Term Durability
Leedings’ polyester acoustic panels are engineered for longevity:
Needling Process: Fibers are mechanically interlocked, preventing loosening unless exposed to temperatures >120°C.
Stability: No warping or softening under normal indoor conditions.
Size Tolerances
Standard Panels:
Length/Width: ±2mm
Diagonal (Catercorner): ±3mm
Large Panels (e.g., 3600mm):
Length/Width: ±5mm
Diagonal: Tolerance increases proportionally.
Customization Option: Specify positive or negative tolerance for projects requiring exact dimensions.
The Leedings Advantage: Precision Meets Sustainability
