Classification of application of automotive laminated nonwoven materials
Automotive filter material For automotive filter materials, early researchers used wet non-woven fabrics, but their overall filtration performance was relatively low . The three-dimensional mesh structure endows needle punched nonwoven materials with high porosity (up to 70%~80%), high capacity, ...Read more -
What are the types of laminated nonwoven materials for automobiles?
Laminated nonwoven material Coating is a process in which a polymer melt is deposited onto a substrate through a coating machine, and then dried to form a protective film on the surface of the substrate. High polymer films are usually polyethylene, polypropylene, or polyester, and are divided int...Read more -
Non conforming non-woven fabric, are these problems occurring during production?
Many manufacturers produce non-woven fabrics that are always unqualified, sometimes with thin sides and thick middle, thin left side, or uneven softness and hardness. The main reason is that the following aspects are not done properly during the production process. Why does non-woven fabric have ...Read more -
