Needle-punched nonwovens are a kind of dry nonwovens. Staple fibers are loosened, carded and laid into a web, which is then reinforced into cloth with a needle. The needle has a hook, the fiber web is repeatedly punctured, and the hook is strengthened to form needled nonwovens.

Automobile interior non-woven fabric to meet what standards

Non-woven fabrics have no warp and weft threads, cutting and sewing are very convenient, and light weight, easy to shape, loved by handcraft lovers. Because it is a kind of don\'t need to be formed by spinning weaving fabric, just short textile fiber or filament for directional or random arrangement

Sponge composite is by heating, pressure, with adhesive to the same or not the same material of two or multiple layers combined as a whole method. The method of forming and processing multi-layer sponge composite cloth with water-based adhesive under heating and pressure of the drum of foam composite machine.

Honeycomb panels are mainly used in the following products: 1. Car trunk cover Three layers of honeycomb panels can be used in the trunk cover, light weight, high strength, waterproof and heat insulation 2. Car, high-speed rail seat back Three-layer honeycomb panels can also be used for seat backrests, which play a role in heat and sound insulation 3. Car roof Two layers of honeycomb panel can be used to make interior decoration of automobile roof 4.Other Fields

Since the honeycomb is a porous discontinuous material, and the cross-sectional area of the solid part is small, the density of the honeycomb is also very small, so the finishing weight is light, and it meets the light weight requirements in aerospace design. Excellent compressive strength, good shear strength, light weight and low density.

The PP honeycomb panel is divided into three layers. The upper and lower are two thinner panels, and the middle is a layer of relatively thick honeycomb core material. Toxic and environmentally friendly, shock absorption and cold resistance, sound insulation and heat preservation, moisture and heat insulation
