Background

Automobile parts are used as the basis of the automobile industry, are necessary factors for supporting the continuous and healthy development of the automobile industry, particularly strong parts are needed to be used as supports when the existing autonomous automobile is developed actively, and the innovation of the parts generates strong thrust for the development of the whole automobile, which are complementary.

The price war that the whole car market is developing more and more is also being the profit of the silkworm food spare part trade, because the waste material that traditional processing produced is more, and the utilization ratio of raw materials for production is low, has increased manufacturing cost, consequently need study more economic and energy-conserving material and use for automobile parts on the basis of guaranteeing product strength.

Disclosure of Invention

The invention aims to provide a non-woven felt decorative part for a vehicle, which solves the problems of high raw material cost and incapability of recycling waste materials and is used for realizing the economic and energy-saving technical effect of automobile parts.

The invention is realized by the following technical scheme: the utility model provides a non-woven fabric felt decorative component for vehicle, includes the non-woven fabrics with the fibre netting of bi-component PET, the fibre includes the cortex fibre and wraps up the intrafibrous sandwich layer fibre of cortex, the sandwich layer fibre includes pure PET long fiber, the cortex fibre includes the feed back PET long fiber.

The invention adopts the bi-component PET fiber with low cost, the pure long PET fiber of the core layer can be recycled for a plurality of times, and the skin layer adopts the recycled PET long fiber, thereby realizing the effects of saving resources and reducing cost.

In order to better realize the invention, further, the mass ratio of the core layer fiber to the skin layer fiber is 1: 0.6-0.9.

In order to better implement the invention, further, the melting point of the core layer fiber is higher than that of the sheath layer fiber.

In order to better realize the invention, the melting point of the core layer fiber is 250-255 ℃, and the melting point of the skin layer fiber is 230-235 ℃.

In order to better realize the invention, the skin layer fibers are fused and bonded into a net by steam heating among the fibers.

In order to better implement the invention, the non-woven fabric felt is further used for decorative parts of vehicles, including cushions, carpets, steering wheel covers and roofs.

The invention has the beneficial effects that:

1. the non-woven fabric produced by using the pure PET and the recycled PET as the raw materials has the advantages of low cost and hundred percent recycling, so that the non-woven fabric has lower economic cost when being used as automobile parts.

2. Compared with other heating modes, the invention has the advantages of energy saving, environmental protection and lower cost by adopting steam heating during web formation heating.

Detailed Description

The invention relates to a non-woven felt decorative part for a vehicle, which comprises a non-woven fabric formed by a bi-component PET fiber in a net, wherein the fiber comprises a sheath fiber and a core fiber wrapped in the sheath fiber, the core fiber comprises a pure PET long fiber, the sheath fiber comprises a return PET long fiber, the cost of the adopted bi-component PET fiber is low, the pure long PET fiber of the core layer can be recycled for multiple times, and the return PET long fiber is adopted in the sheath, so that the effects of saving resources and reducing the cost can be realized.

Preferably, the mass ratio of the core layer fiber to the skin layer fiber is 1: 0.6-0.9.

In this embodiment, the melting point of the core layer fiber is higher than that of the sheath layer fiber, and after the sheath layer fiber is heated and melted, the two fibers are bonded into a web through the sheath layer fiber.

Preferably, the melting point of the core layer fiber is 250-255 ℃, the melting point of the skin layer fiber is 230-235 ℃, and the melting point of the skin layer fiber is lower than that of the core layer fiber, so that the skin layer fiber is melted and the core layer fiber is not melted during bonding, and then the two fibers are bonded together after the skin layer fiber is melted.

In this example, steam heating was used to melt bond the sheath fibers together into a web. The contact heating time is about 90 seconds, the process only needs about 11 seconds, the production efficiency is greatly improved, the energy is saved, and the production cost pressure is reduced.

In the present embodiment, the nonwoven fabric felt is used for decorative parts of a vehicle, including a seat cushion, a carpet, a steering wheel cover, and a roof, and can also be used as parts of a wheel cover, a floor shield, an engine shield, a battery shield, and the like of an automobile.

The following table shows the waste generated by the product (ELITE) and other products

At present, the glass fiber of the national standard can not be exposed, and the glass fiber is still in danger in the transportation process, but the strength of the glass fiber-free product is not enough, meanwhile, the glass fiber production can also generate great environmental pollution, the product of the scheme has no glass fiber waste, and can be recycled for 100% unlimited times, and in addition, PET is cheaper than PP, the material is light, so the advantage of the scheme on the cost price is obvious, and the effect of saving economy and energy for the production of automobile parts can be realized.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and all such changes or substitutions are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
