The sewn non-woven fabric, by changing and enhancing the texture and density of the sewn fabric on both sides, endows the product with strong tensile strength in both longitudinal and transverse directions, a relatively flat surface, good elasticity and stiffness, and a small elongation rate.

With the increasing diversity of people\'s aesthetic perspectives and the rising demand for aesthetics, the interior of a vehicle, as one of its most visually prominent components, naturally garners significant attention from consumers. The design and quality of a car\'s interior not only influence the overall comfort, operability, and aesthetics of the vehicle but also play a crucial role in determining its energy efficiency, safety, and environmental sustainability. XPE car seat insulation pads are composed of chemically cross-linked polyethylene foam materials. These are high-molecular foamed materials produced by blending polyethylene with various additives, incorporating chemical cross-linking agents and foaming agents. Synthetic resins are obtained through addition polymerization reactions, using addition polymerization resins as the base material, with different additives incorporated to meet specific requirements.

Glass Mat Reinforced Thermorplastic (GMT) was introduced in the mid-1960s and is one of the most actively developed composites in the world. This is a novel, energy-saving and lightweight composite material which is based on thermoplastic resin and reinforced by long glass fiber felt or continuous glass fiber felt. GMT has the advantage of material and process properties and can be produced on a large scale, so it plays a large role in replacing traditional materials.

Spunlace nonwovens, also known as spunlace nonwovens, have a unique manufacturing process. By accurately spraying high-pressure microstreams of water onto one or more layers of fiber webs, the fibers intertwine with each other under the impact of water

PP honeycomb panel is made of two thin panels firmly bonded on both sides of a thick honeycomb core material, also known as honeycomb sandwich structure. In addition, honeycomb panel also refers to a large number of cutoff waveguides welded together to form a cutoff waveguide array, forming a large open area, while preventing electromagnetic leakage of the panel.

Now many materials of car interior are made of non-woven fabric, such as car ceiling, car mat, car interior board decoration and so on are made of non-woven fabric, so as car interior, non-woven fabric needs to have the several requirements, we sum up four points to understand.

Dry and wet roof mechanical properties are basically similar, dry process has the advantages of high efficiency and environmental protection, dry roof sensory slightly full; Wet process requires two sets of molds, secondary molding, stable shape, high efficiency, wet process usually uses solvent based adhesive, production process emissions of a large number of organic solvents environmental protection is not as good as dry method.

Needle-punched non-woven fabric is a kind of nonwoven fabric, is the polymer compound cut into fragments, immediately in accordance with the whirlwind or mechanical equipment laid chemical fiber, and then through spines, needle-punched or hot reinforcement, and finally combed into nonwoven fabric.

EVA sheet is the most widely used soft foam material in any industry at home and abroad. It is widely used and related to the basic industries of the national economy.

The application of automobile interior mold is very extensive, we drive daily when we generally only care about the comfort of automobile interior, few people care about the processing and manufacturing of automobile interior mold.
