BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mud-removing mat excellent in anti-slip performance and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, various measures have been made to prevent slipping on a floor contact surface of a backing material for carpet or mat. For example, Japanese Utility Model Application Laid-Open No. 63-35636 and Japanese Utility Model Application Laid-Open No. 63-64841 disclose a plurality of small projections. In addition, the actual development Sho 63-1120
Japanese Patent No. 30 discloses a stack of net-shaped sheets. Further, Japanese Patent Laid-Open No. 3-45214 discloses a coil-shaped continuous fiber adhered in a random direction.

[0003]

However, in all of these prior arts, since the pre-cured carpet or mat is secondary processed, the manufacturing process is complicated. Next takes time. Further, materials and equipment for adhesion or welding, heating means, etc. are required, resulting in high cost and not necessarily satisfactory in terms of product durability. Therefore, an object of the present invention is to provide a mud-removing mat that solves such problems and an efficient manufacturing method thereof.

[0004]

In the mud-draining mat of the present invention, a surface layer of the mat is formed by a loop group of a large number of synthetic resin monofilaments, a back surface layer is formed on the lower surface of the surface layer, and the back surface layer is further formed. An anti-slip layer is integrally formed on the lower surface of the grid with a grid pattern, Roman letters, characters, or the like. Further, the method for producing a mud-dripping mat of the present invention, a large number of synthetic resin molten monofilaments are hung down, and a part of them is provided with a checkerboard-like groove on the circumferential surface, or a groove having a Roman character or a letter is formed. A small diameter loop is formed in the concave groove of the forming roll provided in a part to form an antislip layer with the rotation of the forming roll, and the other part of the monofilament is the antislip layer and the forming roll. To form a back surface layer in the form of a loop, and the rest of the monofilament is received on a water surface lower than the surface of the forming roll and has a larger diameter than the loop group on the back surface layer and an irregular tertiary A surface layer is formed by loops of original curves, and the loops are fusion-bonded to each other at intersections to form an integrated mat.

[0005]

The function of the mud-removing mat of the present invention is to include loop groups of the surface layer,
The distance between the back surface layer and the anti-slip layer provides flexibility and elasticity to provide a comfortable feel when walking and to collect mud. Moreover, the front surface layer, the rear surface layer, and the slip prevention layer are integrally formed, and the slip effect with good durability is maintained.

Further, in the method for producing a mud dropping mat of the present invention, since the molten monofilament extruded from the nozzle is given a complicated internal stress, the viscoelasticity of the molten monofilament causes it to cool and solidify within a time. It has the ability to transform from a straight line to a curved line in response to stress. In the present invention, the surface layer, the back layer and the anti-slip layer of the mat are formed by different methods depending on the required performance by utilizing the physical properties of the polymer. Then, since the mud wiped from the shoes at the time of use sinks from the gap between the loop groups of the front surface layer and the back surface layer of the mat and is collected without being scattered to the outside of the grid-shaped slip prevention layer, The mat can be easily removed by flipping it over, and the workability and efficiency of cleaning are good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is an extruder for melting a soft vinyl chloride resin, a spinning pack 2 is connected to the tip of the extruder, and nozzles (not shown) are arranged below the spinning pack 2 in a three-row arrangement. The monofilament rows F1 to F3 spun from these nozzles are drooped straight.
In the rows of these monofilaments, the frontward F1 forms the anti-slip layer S of the mat, the central F2 forms the rear surface layer L of the mat, and the rearward F3 forms the front surface layer A of the mat.

Reference numeral 3 denotes a row F1 of each of these monofilaments.
A forming roll for forming a loop in each of F3 to F3,
As shown in FIG. 2, a grid-shaped concave groove 4 or a concave groove 4'of Roman characters, letters, etc. is partially provided on the peripheral surface thereof. The forming roll 3 is installed below the spinning pack 2 and rotated in the direction of the arrow. Reference numeral 5 is a pressing roll installed to face the forming roll 3, and 6 is a guide roll of a mat fed from the pair of the forming roll 3 and the pressing roll 5, which is positioned and installed so that the mat can move vertically. And rotate it in the direction of the arrow. 7 is a delivery roll. Reference numeral 8 is a cooling water tank for accommodating the forming roll 3, the pressing roll 5 and the guide roll 6, and adjusts the water surface 9 of the cooling water so as to have a predetermined height below the nozzle surface.

Of the row of monofilaments fed from the spinning pack 2, F1 hangs down to form the molding roll 3
To form a continuous loop L1 in the form of a small circular ring, and is accumulated in the concave groove 4 or the concave groove 4'of Roman letters, letters, etc. provided on the peripheral surface of the forming roll 3, and adjacent loops are The slip preventing layers S are fused at the respective intersections and are formed in a grid pattern as a whole as the molding roll 3 rotates. A row of monofilaments F2 hangs down on the entire surface of the forming roll 3 including the anti-slip layer S thus formed, forming a loop L2, and the loop L2 and the intersection of the loop L1 of the anti-slip layer S are formed. After being fused, the intersections of the loops L2 of F2 are fused to form the back surface layer L, and are transferred to the water surface 9 in accordance with the rotation of the forming roll 3 in a state where they can be fused at high temperature.

On the other hand, a loop L3 larger than the loops L1 and L2 formed by the rows of monofilaments F1 and F2 that droop on the water surface 9 near this position and hang down on the water surface 9 is formed. These loops L3 overlap the loops L2 of the backing layer L and are fused at the intersections of each other to form the surface layer A of the mat. Then, it is transferred straight into water, and the loop L3 of the surface layer A is gradually cooled and deformed and fixed in water to form a three-dimensional complicated curved shape, and the sludge mat M having the shape shown in FIGS. 3 to 5 is formed. It is formed.

As shown in these figures, the loops L1 to L formed by the rows F1 to F3 of each monofilament.
As for the size of 3, the loop diameter becomes smaller as the length until each hanging distance reaches the forming roll 3 having a curved surface becomes smaller. Therefore, the loop diameter L1 of the slip prevention layer S becomes the minimum. The back surface layer L forms a loop L2 larger than the slip prevention layer S. Further, since the drooping distance of F3 forming the surface layer A is the water surface 9, the maximum loop diameter is formed. Then, by slightly changing the mounting height of the forming roll 3 and the height of the water surface 9, the size and shape of the loop diameters L1 to L3, and further the standing angle of the loop L3 of the surface layer A can be easily changed, Mats with different structures can be manufactured.

The mud-removing mat M constructed in this way is
Since the surface layer A forms a three-dimensional three-dimensional curve and the space portion 10 is formed between the back surface layer L and the slip prevention layer S, the cushioning property is excellent and the mud capturing performance is excellent.
The captured mud passes through the back surface layer L and drops, and falls and collects inside the slip prevention layer S having a grid-like checkerboard pattern.
Moreover, the mud accumulated as a checkerboard does not scatter to the outside of the mat M, and the surroundings are not polluted with mud.

[0013]

As described above, the mud dropping mat of the present invention has a composite structure in which the size and shape of the loop formed by the monofilament are different in the front surface layer, the back surface layer and the slip prevention layer. Since it has excellent mud trapping property and permeation settling property, the permeation settling mud does not stay in the grid-shaped anti-slip layer and is not scattered to the outside, and therefore the periphery of the mat is soiled with mud. There is no such thing. And the accumulated mud can be easily removed by flipping the mat,
The mud that adheres to the mat can be easily removed by hitting the mat or washing it lightly with water, and it can always be used in a clean state. Moreover, since the front surface layer, the back surface layer, and the slip prevention layer can be formed continuously and integrally, they can be manufactured at high productivity and at low cost, and by forming an integrated structure, they are excellent in strength and reliably prevent slipping. However, it can be used stably for a long period of time. Since a space is formed between the back surface layer of the mat and the anti-slip layer, it also has excellent cushioning properties.
