Improving the sound insulation of automobiles with pore size control technology for wet non-woven fabrics.

In the automotive industry, sound absorption performance is required to enhance the comfort of the vehicle interior. In particular, reducing noise such as road noise and engine sounds is important for improving customer satisfaction. Insufficient sound absorption performance can lead to difficulties in conversation and feelings of fatigue inside the vehicle. Our pore size control technology achieves effective sound absorption performance by optimizing the pore size of wet non-woven fabrics. 【Application Scenes】 - Interior materials of the vehicle (dashboard, trim, etc.) - Engine room - Underfloor carpet 【Effects of Implementation】 - Reduction of in-vehicle noise - Improvement of comfort - Increase in customer satisfaction
