Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car mat,

The present invention relates to an automotive mat, and more particularly, to a method for manufacturing an automobile mat, in which a portion of fibers of a nonwoven fabric layer is inserted into a fixing portion using a needle puncher, The present invention relates to a car mat.

At the bottom of the vehicle, mats are installed to prevent contamination by soil or foreign matter on the occupant's shoes and to facilitate cleaning. The conventional automobile mat has a structure in which the fixed portion, the nonwoven fabric layer and the carpet layer are stacked in order from the lower side.

The fixing portion is for preventing the automobile mat from slipping due to the shaking of the vehicle or the movement of the occupant after the automobile mat is mounted on the floor of the vehicle.

The conventional fixing part is formed of PVC (polyvinyl chloride) or rubber having a predetermined frictional force, and a plurality of embossed support protrusions are formed at a predetermined interval therebetween. However, the PVC not only generates harmful toxic substances and environmental hormones to the human body, but also has a problem that a specific strong smell is left in the vehicle for a long time to give a bad feeling to passengers. In addition, since PVC discharges environmental pollutants such as dioxin at the time of incineration, the use of indoor materials is gradually regulated.

In addition, in the structure in which the fixing portion has the supporting protrusion, slippage may occur unlike the case where the supporting protrusion is worn by frequent friction with the vehicle floor when the automobile mat is used for a long time. In addition, in order to improve the slip prevention effect, the support protuberance may be pointed. In this case, the support protuberances may scratch the floor of the vehicle, thereby causing a problem that the floor of the vehicle is damaged.

On the other hand, although a separate position fixing hole is formed on the mat and a fixing member is protrudingly formed on the floor of the vehicle so as to be inserted into the position fixing hole, this structure is not only complicated in the manufacturing process, There are disadvantages.

In order to solve these problems, a car mat having a fixing portion formed by a double raschel method is disclosed in Patent Publication No. 2014-0042412. The double lacquer has a structure in which a thin support layer is provided on both sides and a plurality of thin synthetic resin connection chambers are attached to the center portion. According to the prior art document, when the connecting chambers of the double lacels are vertically cut to use as the fixing portion, not only the manufacturing process is simple but also the cushion feeling and slip prevention effect of the mat can be improved, It is possible to solve the problem that the floor of the vehicle is damaged.

However, since the conventional double lacquer and the mat having the nonwoven fabric layer use an adhesive on the attachment surface when the fixing portion and the nonwoven fabric layer are bonded, the problem of harmful to the human body and polluting the environment still remains.

In the conventional mat, the adhesive is applied to the contact surface between the fixing portion and the nonwoven fabric layer, and then the adhesive is applied by the compression heating method. At this time, since the laminate of the fixing portion and the nonwoven fabric layer is pressed by the heating roller, So that it is warped in one direction or inclined directionality along the rotation / movement direction of the heating roller.

Therefore, when the mat is not completely fixed to one direction due to such a directionality, a phenomenon occurs in which the mat is pushed in the corresponding direction due to the shaking of the vehicle or the movement of the occupant. It may interfere with the accelerator or cause accidents to the car.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the following embodiments. In addition, to include an element throughout the specification does not exclude other elements unless specifically stated otherwise, but may include other elements.

In the present embodiment, for convenience of explanation, the direction in which the carpet layer is located upward is defined as the lower side and the direction in which the fixing portion is positioned is defined as the lower side in Fig. 1, Define the forward direction as the forward direction.

FIG. 1 is a perspective view schematically showing a car mat according to a first embodiment of the present invention, and FIG. 2 is a sectional view taken on line A-A 'of FIG.

Referring to Figs. 1 and 2, the automobile mat 1 of the present embodiment includes a fixing portion 30; A nonwoven fabric layer 20; And a carpet layer (10); .

The fixing part 30 constitutes the lower part of the automotive mat 1 and includes a supporting layer 31 and a plurality of non-slip protrusions 32 protruding from the bottom surface of the supporting layer 31. At this time, the fixing portion 30 can be manufactured using a double rachel.

The slip prevention protrusion 32 serves to fix the automobile mat 1 in any direction in accordance with the movement of the vehicle or the shaking of the vehicle when the automotive mat 1 is mounted on the floor of the vehicle. Since the non-slip protuberances 32 of the present embodiment are randomly protruded without a certain direction, even if the time after installation is accumulated on the floor of the vehicle, the slip phenomenon does not occur in any one direction. At this time, the non-slip projections 32 may preferably have a length of 1 to 5 mm in order to optimize the non-slip effect and the cushioning feeling. When the length of the slip prevention protrusion 32 is less than 1 mm, the elasticity is restored to a slower recovery, and the feeling of the cushion of the mat may be reduced. When the length of the slip prevention protrusion 32 exceeds 5 mm, The non-slip effect can be lost.

The nonwoven fabric layer (20) is disposed on the upper surface of the support layer (31) of the fixing portion (30). The nonwoven fabric is formed into a felt shape by arranging the fibers in a negative direction (indefinite direction) without joining the woven fabric process. The nonwoven fabric layer 20 of the present embodiment is formed such that a part of the fibers are inserted into the supporting layer 31 of the fixing portion 30 to be entangled with the fibers of the supporting layer 31, And the fixing portion 30 can be engaged with each other.

The nonwoven fabric layer 20 may preferably be made of PET fiber and more preferably a polylactide fiber having a relatively low denier relative to the fibers constituting the support layer 31 of the fixing portion 30. In this case, In this case, the fibers of the nonwoven fabric layer 20 can be easily inserted into the support layer 31 and the effect of tangling with each other can be improved.

For example, the nonwoven fabric layer 20 may contain 30 to 70% of polyester fibers of 1.5 to 3 denier and 7 to 15 denier polyester fibers, respectively. In this case, The binding force between the fixing portion 30 and the nonwoven fabric layer 20 can be improved while being more effectively entangled with the fibers.

The carpet layer 10 constitutes the upper part of the car mat 10 and is frictionally coupled to the upper surface of the nonwoven layer 20. [ At this time, an adhesive layer 40 made of, for example, PE (polyethylene) may be interposed between the carpet layer 10 and the nonwoven fabric layer 20. Further, the carpet layer 10 can be produced according to various designs and preferences, and the carpet layer 10 of the present invention does not limit specific fibers.

3 is a cross-sectional view schematically showing a car mat according to a second embodiment of the present invention.

Referring to FIG. 3, the nonwoven fabric layer 20 of the present embodiment includes a lower nonwoven fabric 21 and an upper nonwoven fabric 22 that is seamed on the upper surface of the lower nonwoven fabric 21.

The lower nonwoven fabric 21 is disposed on the upper surface of the support layer 31 of the fixing portion 30 and is made of a thin and soft first polyester fiber having a relatively low denier relative to the fibers constituting the support layer 31 of the fixing portion 30 It can be made compact. The first polyester fibers of the lower nonwoven fabric 21 are entangled with the fibers constituting the support layer 31 of the ascending and descending fixing portion 30 of the needle puncher in the below- 30 to each other.

The upper nonwoven fabric 22 may be disposed on the upper surface of the lower nonwoven fabric 21 and may comprise a second, higher and harder second polyester fiber relative to the first polyester fiber of the lower nonwoven fabric 21. If the entire nonwoven fabric layer 20 is made only of fibers having a low denier as in the first embodiment, the mat of the automobile becomes complicated and it is difficult to maintain the shape of the mat, and the strength may be lowered as a whole. In the second embodiment, the upper nonwoven fabric 22 made of thick fibers constitutes the upper portion of the nonwoven fabric layer 20, so that the surface of the automobile mat 1 is hardened and the function of maintaining the shape of the mat is improved have.

In this embodiment, a part of the first polyester fibers of the lower nonwoven fabric 21 is inserted into the support layer 31 of the fixing portion 30 to be entangled with the fibers of the support layer 31, The nonwoven fabric 21 and the supporting layer 31 of the fixing portion 30 can be coupled to each other so as to be caulked. In addition, some of the first polyester fibers of the lower nonwoven fabric 21 are inserted into the upper nonwoven fabric 22 and are entangled with the second polyester fibers to bond the lower nonwoven fabric 21 and the upper nonwoven fabric 22.

As described above, since the automotive mat of the present embodiment does not perform the compression heating and fixing, the connecting chambers 32 of the fixing portion 30 do not have the directionality, so that when the vehicle mat is installed on the floor of the vehicle, There is an effect that can be maintained.

Hereinafter, a method for manufacturing the automotive mat of the present invention will be described. Here, the automobile mat is applied to the structure of the second embodiment of Fig. 3, but it goes without saying that the structure of the first embodiment of Figs. 1 and 2 may be similarly applied.

4A and 4B, a known double lacelle manufacturing apparatus is used, and a plurality of connection chambers 330 are disposed between a pair of supporting layers 310 and 320 facing each other to form a double lacelle 300 And the connection chamber 330 of the double lacelle 300 is vertically cut along the imaginary cutting line C to manufacture the fixing portion 30. [ At this time, the connection chambers 330 are formed as a plurality of non-slip protrusions 32 protruding in a length of 1 to 5 mm on one surface of the support layer 31 of the fixing portion 30. [ In addition, the slip prevention protrusion 32 of the present embodiment is excellent in the slip prevention effect when the floor is mounted, even though it is not in the form of a hook, so that the bottom of the vehicle can be prevented from being damaged when the mat with the conventional hook type support protrusion is detached. The thus fabricated fixing portion 30 is wound on a fixed-portion supplying roll for a post-process.

5 to 6B, the nonwoven fabric layer 20 is disposed on the upper surface of the support layer 31. Next, The fixing portion 30 is continuously supplied from the fixed portion supplying roll 110 and the nonwoven fabric layer 20 is continuously supplied so as to cover the upper surface of the supporting portion 31 of the fixing portion 30. [ The nonwoven fabric layer 20 may be wound on a separate nonwoven fabric layer supply roll (not shown) if necessary, and the nonwoven fabric layer 20 may be coalesced on the upper surface of the lower nonwoven fabric 21 and the lower non- And an upper nonwoven fabric layer (22).

At this time, since the fixing portion 30 of the fixing portion 30 of the fixing portion 30 is wound in the form of the first roll, there is a possibility that the non-slippery protrusions 32 are tangled or aggregated when loosened and supplied. In this embodiment, at least one slack roller 121, 122 may be provided on the path through which the fixing portion 30 is supplied, if necessary. In this embodiment, two relaxation rollers are shown as an example, but one or more relaxation rollers may be arranged as needed. The relaxation rollers 121 and 122 spread out the plurality of non-slip protrusions 32 formed on one surface of the support layer 31 before the fixing portion 30 is supplied to the bottom surface of the nonwoven fabric layer 20, .

Next, the stacked body of the fixing portion 30 and the nonwoven fabric layer 20 is transferred to the needle puncher 200 side. 6A and 6B, the needle puncher 200 includes a support 211, a plurality of needles 212 protruding from the bottom of the support 211, at least one needle 212 formed on each needle 212, (Not shown).

7, for example, the needle 212 has a flat wing 213, and the wing 213 may have a tapered shape such that the lower end is pointed. The locking protrusion 215 may be formed in a part of the wing portion 213 by cutting a groove 214 having a predetermined depth so as to be upwardly inclined so that the upper portion divided by the groove 214 becomes a locking protrusion 215 have. The needle puncher 200 constructed as described above is repeatedly raised and lowered when the laminate passes under the needle puncher 200 so that the needles 212 and sharp portions of the lower ends of the wing portions 213 are pushed up from the nonwoven fabric layer 20, (31).

At this time, when the needle puncher 200 descends, some of the polyester fibers of the nonwoven fabric layer 20 are caught by the engagement protrusions 215 of the needles 212 and pulled into the support layer 31, The polyester fibers of the nonwoven fabric layer 20 inserted into the nonwoven fabric layer 20 are tangled with the fibers of the supporting layer 31 to bond the nonwoven fabric layer 20 and the fixing portion 30 to each other.

The nonwoven fabric layer 20 may be formed of polyester fibers of relatively low denier relative to the fibers of the support layer 31 so that some of the polyester fibers of the nonwoven fabric layer 20 are inserted into the fibers of the support layer 31 The bonding force between the nonwoven fabric layer 20 and the supporting layer 31 can be further improved.

In the present embodiment, the lower nonwoven fabric 21 of the nonwoven fabric layer 20 is formed of a first polyester fiber having a low denier with respect to the fibers of the support layer 31, and the upper nonwoven fabric 22 is formed of the lower nonwoven fabric 31, Lt; / RTI > of the second polyester fiber of the tandem type.

When the needle puncher 200 is lowered on the upper nonwoven fabric 22, a part of the first polyester fibers is pulled by the hooking protrusion 215 of the needle 212 and inserted into the support layer 31, and the needle puncher 200 The action of inserting the first polyester fibers into the upper nonwoven fabric 22 is repeated while the lower first nonwoven fabric 21 is hooked on the lower portion of the groove 214 and the first polyester fibers of the lower non- The upper nonwoven fabric 22, the lower nonwoven fabric 21 and the fixing portion 31 are bonded to each other with the fibers of the upper nonwoven fabric 31 and the second polyester fibers of the upper nonwoven fabric 22, respectively.

The needle puncher 200 includes a plurality of unit punchers 200 whose lengths of the needles 212 and the engagement protrusions 215 are gradually reduced along the conveying direction of the laminate composed of the nonwoven fabric layer 20 and the fixing portions 30, ≪ / RTI > At this time, the tightness of the needle puncher 200 may be gradually decreased along the conveying direction of the laminate, so that the bonding force between the nonwoven fabric layer 20 and the fixing portion 30 can be further improved.

In this embodiment, the needle puncher 200 may be composed of first to third unit punchers 210, 220, and 230 arranged along the conveying direction of the stacked body. However, this is an embodiment, and the needle puncher 200 may be composed of two unit punchers or four or more unit punchers if necessary.
