Abstract

The invention provides a producing method for a car interior carpet. The carpet produced through the producing method is of an integral structure, the performance indexes such as sound absorption, heat insulation, attractiveness, individuation, dust prevention, easy cleaning and comfort sense of touch of the carpet of a driving cab reach the three-level international advanced level, the design requirements of environment protection, attractiveness and comfortableness and sound insulation and heat insulation of the car driving cab are met; a pneumatic pre-feeding device is adopted in the blister packaging procedure, the thickness of foam leather of a large-sized surface and a large-stretching part of a product is ensured, the whole quality of the product is improved, consistency of the quality of the product is ensured, the producing efficiency is greatly improved, the labor intensity is reduced, and the producing cost is reduced substantially; sound-insulation and heat-insulation felts are pressed and attached, not only is the sound-insulation and heat-insulation performance of the product improved, but also the appearance of the product is smooth and attractive, the sense of touch is comfort; and no harmful substances is generated in the whole producing process of the product, and the product is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of automotive interior accessories, and in particular relates to a production method of an automotive interior carpet. Background technique [0002] Automotive interior parts are generally installed inside the cab to beautify the cab environment, sound-absorbing, heat-insulating and dust-proof. With people's higher requirements for the environment of the car cab, environmental protection, beauty, comfort and personalization are the basic requirements for car interior parts. In the prior art, automobile carpets are all produced by foaming technology and spliced ​​in multiple pieces. The sound-absorbing and heat-insulating performance cannot be significantly improved, the dust-proof effect is poor, it is not easy to clean and affect the overall appearance, and the production cost is relatively high. The environment cannot be improved. Contents of the invention [0003] In order to solve the above problems,...
