Embodiment Construction

[0038] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0039] The invention provides a method for manufacturing a hemp fiber automotive interior trim. The hemp fiber automotive interior trim is composed of hemp fiber and polypropylene fiber. The proportion of fibers used in the two materials is: jute fiber 45%, polypropylene fiber 55%. The production methods of two kinds of hemp fiber automotive interior parts are provided below.

[0040] Method 1: if figure 1 As shown, the packaged raw materials are opened and loosened, jute fibers and polypropylene fibers are mixed in the carding machine according to the proportion, and the fibers are formed into a net at the same time, and then needled into a felt by a needle punching machine, and the felted product is processed. Slicing process, first baked by hot air and bonded on the surface, the bak...

Abstract

The present invention relates to a fibrilia automobile inner decoration member and a method of manufacturing the same, the steps is that implementing a opening treatment to packaged raw material, mixing jute fiber and polypropylene fiber according to proportionality in a cotton opener, and fiber netting simultaneously; then needling to form a felt by a needle machine, and implementing a sliced sheet treatment to the product after felting; baking and heating the felt directly in a baking oven to bond the surface, the baking temperature is from 180 to 200 DEG C; then cold press molding by a product mold, finally manufacturing a finished product; or preparing the belt into a sheet material to store, then baking and heating the sheet material, and a corresponding product molding according to requirements.

Description

technical field [0001] The invention belongs to the field of manufacturing automotive interior parts, and relates to a hemp fiber automotive interior part and a production method thereof. Background technique [0002] Existing automotive interior products mostly use chemically synthesized materials (such as PP, ABS, etc.), which are limited in resources, non-renewable, consume a lot of energy, and pollute the environment during processing, while lightweight and environmental protection are The main direction of the development of automotive materials today, the application proportion of various materials in automobiles has undergone obvious changes, and the amount of composite materials will have a greater development. Among them, natural fiber composite materials are characterized by their unique environmental protection, affinity, and light weight. Advantages such as quality and low price are favored by automobile manufacturers, to meet the needs of environmental protectio...
