BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a skin for a car floor carpet,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin for a car floor carpet, and more particularly, to a skin structure for a car floor carpet having excellent absorption performance.

Generally, a floor carpet dl that performs a function of sound absorption and the like is provided on the floor of the vehicle, that is, on the floor, while making the inside of the vehicle look good.

Such floor carpets are provided to cover the upper surface of the vehicle body floor including the area around the seat so as to cover the body parts welded to the vehicle body, It is one.

In addition, it is mainly used for shutting off heat transmitted from the engine, or absorbing or shielding noise or vibration appropriately.

1, the floor carpet is manufactured by adhering the skin portion 110 and the lower pad portion 120, which are formed of a single layer coated with the normal latex, on the adhesive layer 130, which is an intermediate layer, do. As shown in FIG. 2 and Korean Patent Laid-Open Publication No. 10-2006-0134559, the conventional skin portion is generally coated with a polyethylene film layer 220 at the bottom of the monolayer 210. However, when the skin coated with the polyethylene film is bonded to the pad, the adhesive force is weak, and if the polyethylene skin film is used for a long period of time, it tends to separate and can not exhibit a sufficient sound absorbing performance.

That is, the polyethylene coating is intended to achieve a complete sound insulation structure, and the sound absorption performance is insufficient.

Korean Patent Publication No. 10-2006-0134559

3, the structure of the skin for a car floor carpet of the present invention will be described in detail.

The skin for a car floor carpet of the present invention comprises a backing layer 330 made of a felt felt, a polyester ventilation control layer (not shown) bonded to the backing layer 330 by needle punching on the backing layer 330 320 and an upper artificial layer 310 bonded to the ventilation control layer 310.

The upper end monolayer 310 of the present invention is applicable to both latex-coated fabric and latex-free fabrics patented by the present applicant in 2016.

The ventilation control layer 320 is formed of polyester, for example, a polyethylene terephthalate (PET) film, and the ventilation control layer 320 is formed with a ventilation hole 321 by needle punching with the lower backing layer 330 . The lower backing layer 330 layer is formed by felt produced by needle punching. Therefore, the file of the layer of the lower backing layer 330 comes to the vent hole 321.

The PET film used for the ventilation control layer 320 has two layers, a supporting layer having a melting point of 200 degrees or more, which is not melted at the time of molding, and a bonding layer having a melting point of 110 to 160 degrees, Lt; / RTI > In the absence of a supporting layer having a high melting point, it is difficult to dissolve in the molding cavity and serve as a ventilation control layer. In the case where only the supporting layer is provided, bonding strength is lowered because it is bonded only by needle punching after molding.

The main reason why the conventional PE coating was applied is to supplement the rigidity because the molding shape of the floor carpet fabric should be maintained after molding. In the present invention, the backing layer 330 plays a role of reinforcing rigidity. The backing layer 330 comprises a sacrificial layer and 10 to 50 weight percent of a low melting point polyester. The conventional PE coating provides a complete sound insulation structure, but the backing layer 330 of the present invention improves the sound absorption performance with the porous nonwoven fabric.

When a latex-free fabric is applied to the far-end layer 310, it is possible to provide a 100% polyester recycled floor carpet skin.

Fig. 4 shows the manufacturing process of the present invention.

First, a backing layer is formed by a needle punching process 410 in a downward direction. And a polyester film formed in two layers is inserted thereon. The polyester film is formed of a general polyester film on top and an adhesive layer on the bottom as shown. A needle punching 420 is performed in the above direction to form perforations in the polyester film. The film is laminated 430 by a calendar roll.

Spraying PET powder onto the film, laminating it with the outer layer using a thermosetting oven (440), cooling (450) and cutting (460) using a chill roll.

5 is a photograph of the surface of the ventilation control layer formed in a state in which the backing layer and the ventilation control layer are laminated in the joining step 430. [ 5A shows a case where the needle density is 12st / cm 2, and FIG. 5B shows a case where the needle density is 8st / cm 2.

6, there is shown a photograph of a laminate 440 of the ventilation control layer and the single layer. As can be seen from FIG. 6A, the backing layer file is protruded through the air holes of the ventilation control layer, and the adhesive strength can be improved when the adhesive powder is sprayed by these files as shown in FIG. 6B.

The present invention will now be described in more detail by way of examples,

Comparative Example 1

The fabric coated with latex (weight 740 gsm) was coated with PE at 250 gsm. A specimen with a weight of 1890 gsm was made by bonding 900 gsm pad. The absorption sound performance was measured and shown in FIGS. 7 and 8. FIG. The peel strength between the farthest layer and the film layer was measured, but the adhesion between the hot melt and the film was not achieved, and the bonding strength was remarkably decreased, and the peel strength measurement was impossible.

Example 1

The PET film was needle punched with a needle felt of 350 gsm at a needle density of 8 st / cm 2 and a thickness of 11 mm, PET powder was sprayed onto the film, and a thermosetting oven was used to laminate the fabric with latex-coated fibers (weight: 650 gsm) Pads were bonded and a specimen having a weight of 1850 gsm was prepared. The absorption sound performance was measured and shown in FIGS. 7 and 8. FIG.

Example 2

The PET film was needle-punched with a needle span of 12 g / cm2 and a thickness of 12 mm on a 350 gsm hand made felt, PET powder was sprayed onto the film, and a thermosetting oven was used to laminate the latex coated fabric (weight 650 gsm) Pads were bonded and a specimen having a weight of 1850 gsm was prepared. The absorption sound performance was measured and shown in FIGS. 7 and 8. FIG. The peel strength between the fabric layer and the film layer was measured and the peel strength was 1.5 Kg.f / inch.

Comparative Example 2

550gms of PET felt was sprayed with 200gms of weight and bonded with latex coated fabric (weight 650gsm) using a thermosetting oven and attached with 900gsm of plush pads to make specimens weighing 1850gsm. The absorption sound performance was measured and shown in FIGS. 7 and 8. FIG.

Comparative Example 3

450gms of felt felt was sprayed with PET powder and laminated with a latex coated fabric (400gsm weight) using a thermosetting oven and bonded with 900gsm of plush pad to make a specimen of 1750gsm in weight. The absorption sound performance was measured and shown in FIGS. 7 and 8. FIG.

As can be seen from the results of FIGS. 7 and 8, when the conventional PE coated fabric is used, the sound insulating performance is excellent but the sound absorbing performance is deteriorated due to complete sound insulation. On the contrary, the structure having the ventilation control layer made of the powder of Comparative Example 2 As in Comparative Example 3, a completely sound-absorbing structure having only a backing layer and no ventilation control layer is excellent in sound absorption performance but has a disadvantage in that sound insulation performance is poor.

In the embodiment of the present invention, it is possible to provide a carpet for a car floor that is excellent in both sound absorption performance and sound insulation performance.

Also, unlike the conventional case where the pads are directly bonded to the film, the backing layer pile up by the punching improves the bonding strength with the farthest layer, so that the durability is excellent.
