Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a non-slip carpet.

[0002]

2. Description of the Related Art In general, carpets are rugs made of felt, woven fabric, non-woven fabric and the like, and are used for floors of buildings such as houses and buildings, floors of vehicles such as automobiles, and the like.

[0003] Depending on the material of the carpet and the material of the floor on which it is laid, it is likely that the carpet will slide on the floor.

In order to prevent this, a lining made of a synthetic resin is provided on the carpet, and a projection is formed on the lining to increase the surface area with the floor surface, thereby increasing friction and suppressing slippage. Have been done.

[0005]

However, when the carpet starts to slide when the protrusions are provided on the above-mentioned lining,
The contact portion between the carpet and the floor is likely to be only the top of the protrusion, and the contact area with the floor is rather reduced, so that slippage may be promoted.

In particular, when a carpet having a synthetic resin lining is additionally laid on a floor on which a carpet is already laid, such as an automobile, the synthetic resin projection of the lining has a certain size. Therefore, it is not easily entangled with the raised portions of the carpet pile or cut pile laid on the floor. For this reason, when the carpet having the synthetic resin lining starts to slide, only the tip of the raised portion and the tip of the projection come into contact with each other, and the contact area with the floor is reduced, and sliding is promoted.

[0007] Therefore, an object of the present invention is to solve the problem that when another carpet is laid on a carpet already laid on the floor,
The purpose is to increase the friction between the two carpets and suppress slippage.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method of forming a thermoplastic resin sheet extruded from an extruder and rolling the same together along the back of the carpet when rolling the sheet. In the method for manufacturing a carpet having a lining, during the rolling, the surface of the thermoplastic resin sheet opposite to the surface along which the carpet runs, together with the back surface of the sheet in which short rigid fibers are raised on the front surface, It is characterized by rolling.

Further, the tip of the rigid fiber can be curved in a hook shape.

If the short rigid fibers of the sheet provided on the lining of the carpet having a lining made of thermoplastic resin enter the carpet already laid on the floor surface, and if the ends of the rigid fibers are curved, the floor will already be covered. The entanglement with the pile or cut pile of the raised portion of the carpet laid on the surface increases the frictional resistance between the two. For this reason, slippage between the two can be suppressed.

In addition, in both carpets, since the short rigid fibers of the sheet are only intruded into the raised portion of the carpet on the floor side or are entangled with each other, the carpet having a lining made of a thermoplastic resin can be easily peeled off. Can be.

Embodiments of the present invention will be described below with reference to the drawings.

The method for producing a carpet having a non-slip thermoplastic resin lining according to the present invention (hereinafter referred to as "the carpet according to the present invention") is as shown in FIG. 1 or FIG. Then, the thermoplastic resin sheet 3 is extruded from the T-die 2 attached to the tip of the extruder 1.
The thermoplastic resin sheet 3 that has just been extruded is at a temperature higher than the glass transition point of the thermoplastic resin, and is passed through the rolling rollers 4 so that the thickness is adjusted and cooling is performed. The above thermoplastic resin sheet 3
Are rolled together with the back side of the carpet 5 when rolling through the rolling rollers 4.

Further, at the time of the above-mentioned rolling, a sheet (hereinafter, referred to as a “rigid fiber containing sheet”) in which short rigid fibers are raised on the surface of the thermoplastic resin sheet 3 opposite to the surface along which the carpet 5 extends. Are rolled together along the back surface of the sheet. That is, as shown in FIG. 1, each surface of the high-temperature thermoplastic resin sheet 3 extruded from the T die 2
The back surface of the carpet 5 and the back surface of the above-mentioned rigid fiber-containing sheet 6 are rolled along the rolling roller 4 at the same time.

During this rolling, the resin of the thermoplastic resin sheet 3 permeates between the fibers of the carpet 5, and the carpet 5 and the thermoplastic resin sheet 3 are integrated. by this,
A lining made of thermoplastic resin can be attached to the carpet 5.

Further, at the time of this rolling, the thermoplastic resin sheet 3
Resin seeps between the fibers of the cloth of the above-mentioned rigid fiber containing sheet 6, and the rigid fiber containing sheet 6 and the thermoplastic resin sheet 3 are integrated. Thereby, the rigid fiber containing sheet 6 can be attached to the lining of the carpet 5.

The thermoplastic resin used for the thermoplastic resin sheet 3 may be any resin as long as it has thermoplasticity, but a resin having flexibility when formed into a sheet is preferred. This is because the carpet according to the present invention is detachable from the carpet already laid on the floor, and therefore, it is preferable that the carpet can be rolled up and stored when it is removed.

As shown in FIG. 3, the rigid fiber-containing sheet 6 is composed of short rigid fibers 7 and a fabric portion 8.
Is a sheet in which the rigid fibers 7 are fixed to the fabric portion 8 while standing up from the fabric portion 8. The rigid fibers 7 are made of hard fibers such as polyester, polypropylene, and nylon. The fabric portion 8 may be any material that can fix the rigid fibers 7, such as a woven fabric or a nonwoven fabric, and at the same time, the resin of the thermoplastic resin sheet 3 can permeate. As a method of fixing the rigid fiber 7 to the fabric portion 8, the rigid fiber 7
Various methods can be adopted, such as a method of sewing the material into the cloth portion 8, a method of implanting the material, and a method of heat fusion.

The shape of the rigid fiber 7 may be a straight straight line or a curved line. Also,
The tip may be curved like a hook. Above rigid fiber 7
Is curved, the portion where the tip of the rigid fiber 7 is fixed to the cloth portion 8, that is, the relationship between the fixed portion and
Based on the direction perpendicular to the cloth portion 8, the rigid fiber 7
The angle between the line connecting the tip of
Is preferable, and 0 to 30 ° is more preferable. The angle is 0
Is preferable because it means that the rigid fibers 7 are linear. On the other hand, if the angle exceeds 60 °, it may be difficult to enter between the fibers of the carpet already laid on the floor.

The rigid fiber-containing sheet 6 in which the rigid fibers 7 are straight or curved enters between the fibers of the carpet already laid on the floor. Therefore, when the carpet according to the present invention is laid on the carpet already laid on the floor, side slip can be prevented. Further, by lifting the carpet according to the present invention, the carpet already laid on the floor can be easily removed without damaging it.

As the rigid fiber-containing sheet 6, a sheet in which the tip of the rigid fiber 7 is curved in a hook shape and the surface of the cloth portion 8 is densely formed can be used. This sheet is a sheet used for a so-called hook-and-loop fastener. The hook-and-loop fastener sheet is entangled with the raised portion of the carpet already laid on the floor by the hook-shaped rigid fibers on the surface thereof, so that the carpet according to the present invention can be fixed on the carpet already laid on the floor. . Moreover, removal can be easily performed by peeling off the carpet according to the present invention.

The rigid fiber-containing sheet 6 does not have to be provided on the entire back surface of the carpet according to the present invention. For this reason, a tape-shaped rigid fiber-containing sheet 6 having a certain width may be used. As shown in FIG. 2, if the tape-shaped rigid fiber-containing sheets 6 are arranged at predetermined intervals and are rolled by the rolling roll 4, as shown in FIGS. The carpet according to the present invention provided with the sheet 6 can be obtained.

Further, when the above-mentioned sheet for hook-and-loop fastener 6 'is used as the rigid fiber-containing sheet 6, the sheet for hook-and-loop fastener is provided on a part of the back surface as shown in FIGS. A carpet according to the present invention provided with 6 ′ can be obtained.

The interval between the rigid fiber-containing sheets 6 is determined in consideration of the use and place of use of the carpet according to the present invention. What is necessary is just to select so that it may exist in the shape.

By using the above-mentioned rigid fiber-containing sheet 6 as a slip-preventing sheet, the carpet 5, the thermoplastic resin sheet 3 and the rigid-fiber-containing sheet 6 have at least a three-layer structure in this order. A non-slip carpet according to the present invention is obtained.

The carpet 5 includes felt, woven fabric,
A general term for cloth rugs such as nonwoven fabrics, also called carpets.
Any of them can be used. However, the main body should just be what can permeate the resin of the thermoplastic resin sheet 3, such as a woven fabric, a nonwoven fabric, and felt.

The obtained carpet according to the present invention comprises:
As shown in FIG. 5, by impregnating the resin of the thermoplastic resin sheet 3, the carpet 5 and the rigid fiber-containing sheet 6 are integrated with each other, so that the sewing and the adhesive for joining these are unnecessary. In addition, since it is manufactured at a time by the above method, the manufacturing process is simplified.

The carpet according to the invention is laid on a carpet already laid on the floor. The carpet already laid on the floor needs to be a carpet that has room for the rigid fibers 7 because the rigid fibers 7 of the rigid fiber-containing sheet 6 of the carpet according to the present invention enter. In addition, when the hook-and-loop fastener sheet 6 ′ is used as the rigid fiber-containing sheet 6, it must be a carpet having a raised portion because it is entangled with the hook. Examples of the raised portion include piles, cut piles, and upright fibers when the carpet body is made of felt.

[0029]

According to the present invention, a rigid fiber-containing sheet can be provided on a carpet without sewing or application of an adhesive, and can be easily manufactured.

Further, since the fixing is performed using the rigid fiber-containing sheet, the displacement of the carpet according to the present invention is prevented, and the carpet is easily detached.

In particular, when the rigid fibers of the rigid fiber-containing sheet are linear, if the rigid fibers are laid on a carpet already laid on the floor, the rigid fibers enter the carpet already laid on the floor, and according to the present invention. Carpet displacement is prevented. Also, the carpet already laid on the floor can be easily attached and detached without damaging it.

Further, when the rigid fibers of the rigid fiber-containing sheet are hook-shaped, if the rigid fibers are laid on a carpet already laid on the floor, the rigid fibers are entangled with the napped portions of the carpet already laid on the floor. The displacement of the carpet according to the invention is prevented. It is also easy to attach and detach.

When the carpet according to the present invention is used as a carpet mat for an automobile, the carpet can be prevented from being displaced, so that dirt in the car can be minimized and safety during driving is improved.
