[0001] The utility model relates to the technical field of fiber fabric materials, in particular to a wood pulp fiber fabric material for automobile interiors. Background Technique

[0002] Automotive Interior mainly refers to automotive products used for internal modification of automobiles, covering all aspects inside the automobile. For example, automobile steering wheel covers, automobile seat cushions, automobile floor mats, automobile pendants, interior ornaments, storage boxes, etc. are all automotive interior products. What we call automotive interior in China is actually "Interiors System" in English. Since these automotive parts have a certain decorative function, the current common translation in the industry is "automotive interior". However, from the English "Interiors", we can know that these parts not only have a decorative function, but also have very rich functional, safety, and engineering attributes.

[0003] The research on automotive interiors has also been a key research focus in recent years. Several major automotive suppliers have successively carried out patent layouts in the field of automotive interiors. Generally speaking, automotive interior materials are generally composites of polypropylene and / or polyester and hemp fibers. However, there is still room for improvement in the structural strength and flexural strength of this composite material. Content of the Utility Model
