Feasibility of Automotive Soundproofing Material Production Line

Automotive soundproofing materials are an important component for improving interior noise and enhancing driving comfort. Currently, common automotive soundproofing material production lines in the market mainly include polyester (PET) fiber sound-absorbing materials and bicomponent sound-absorbing materials.

1. Polyester (PET) Fiber Sound-Absorbing Material

Web Formation: Carding process.
Bonding Method: Needle punching or thermal bonding.
Surface Treatment: Can be laminated or treated for waterproofing, fire resistance, or other functional enhancements.
Advantages:

(1) Eco-friendly: Made from recycled PET fibers (RPET), contributing to sustainability and aligning with green trends.

(2) Excellent sound absorption: Its porous internal structure provides high sound absorption, especially effective for mid-to-high-frequency noise.

2. Bicomponent (PP+PET) Sound-Absorbing Material

Web Formation: Combination of carding and spunbonding processes.
Bonding Method: Thermal bonding.
Surface Treatment: Can include sound-absorbing coatings or treatments for flame resistance and waterproofing.
Advantages:

(1) Cost-effective: Simplified production process with high efficiency.

(2) Customizable: The performance (soundproofing and insulation) can be tailored by adjusting the ratio of PET to PP fibers.

(3) Multifunctional: Offers soundproofing, insulation, and filtration in one material.

(4) Lightweight: Lightweight and loose structure, making it an excellent choice for automotive soundproofing.

Future Trends

1. Eco-friendliness and Sustainability: Both materials will see increased use of recycled fibers.

2. Application of High-Performance Materials: With advances in technology and higher customer demands, the bicomponent soundproofing materials will gain more competitiveness in high-end markets.
