Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an integrated mat with a pattern for dust control (dust removal or dust prevention). To provide an integrated mat with a pattern, which has a clear pattern, has a stepped finish, and can stably maintain its state even under usage conditions.

(Prior art and its problems) Conventionally, in order to prevent dust attached to the soles of shoes from being brought indoors, dust-collecting pine has been installed at the entrances and entrances of offices, stores, residences, etc. etc., and are used. Some of this type of pine has designs on its surface, such as letters, pictures, marks, etc., which are separated by color from the background part. While this patterned mat is used while being repeatedly washed and regenerated, the pile threads in the back ground part and the pile threads in the pattern part become entangled with each other in the boundary area between the back ground part and the pattern part. , since the colors of the two threads are different, the color of the boundary area takes on an intermediate color, and as a result, the design gradually becomes blurred.

There is also a method of forming a pattern by making the pile threads in the background part and the pile threads in the pattern part the same color, and making only the outline part a different color from the background part. In this method, the outline part is tufted with pile yarn of a different color from the pile yarn of the background part, or the pile yarn of the outline part is dyed a different color, and the outline part is further colored with a different color. The contours are formed by electrostatic flocking of the fiber flock. However, even if the contour is formed by such a method, there is a drawback that the contour becomes unclear and the pattern gradually becomes blurred while the mat is in use.

The purpose of putting a pattern on a dust control mat is to give an impression of the store where the mat has been installed to people passing over the mat, to promote the store, or to attract attention.
When the design becomes blurred, the significance of the design is lost, and although the mat still has sufficient dust control performance, it loses its commercial value and shortens the life of the mat.

(Objective of the invention) The object of the invention is to provide a patterned integrated mat having a clear pattern.

Another object of the present invention is to provide a patterned integrated mat with a stepped finish and a high-class feel.

A further object of this invention is to maintain a clear pattern and consistent finish even when the patterned dust control mat is used under extremely harsh conditions such as repeated rentals, cleaning, and regeneration. The purpose is to provide a matte with a design.

(Structure of the invention) The present invention provides an integrated mat for dust control consisting of a base fabric, pile yarn tufted to the base fabric, and a rubber backing layer applied to the back side of the base fabric. The pattern is formed by a groove formed by partially pruning, and by pruning only the pile threads forming one side of the structure, only one side is inclined with respect to the base fabric surface. This is an integrated mat with a pattern.

(Operation and Effect of the Invention) As described above, in the integrated mat with a pattern of the present invention, a groove of a specific shape is formed on the mat surface, and the pattern is formed by the groove functioning as an outline part. Therefore, the pile threads in the grooves forming the contour part are of the same quality as the pile threads in the back ground part and the pattern part.
Even if they are the same color, it is important to observe them from a distance, as when laying the mat, and because the density and direction of the pile threads relative to the viewing direction are different between the outline, background, and pattern parts, only the outline is visible. The colors appear to be different, and the pattern area can be clearly distinguished from the background area. Furthermore, since the groove has a specific shape as described above, the density and direction of the pile threads in the contour part with respect to the observation direction vary depending on the location of the contour part, so it can be seen by observing from a distance. It looks like Mr. Dantsu. By dyeing the pile threads in the background, pattern and contour areas in various combinations of different colors, the above features can be further emphasized.

Furthermore, since the grooves are formed in a specific shape as described above, the integrated mat with the design of the present invention can be installed in passageways and entrances and is trampled on by many people. Even after repeated reproduction processing, the contours do not disappear, the pattern area and the background area are clearly distinguished, and the continuous finish is maintained.

Therefore, the patterned integrated mat of the present invention does not blur or disappear even after being rented, washed and regenerated many times, so unlike conventional patterned dusting mats, the patterned area does not become diluted. There is no disadvantage that the design part becomes meaningless due to deterioration or disappearance and the product life is shortened, and the product life as a patterned mat can be stably maintained until the physical life limit of the mat. play.

(Preferred embodiment of the invention) The invention will now be described with reference to the accompanying drawings.

Figure 1 shows one of the patterned integrated mats of the present invention.
FIG. 2 is a plan view showing a pattern portion of the embodiment, and FIG. 2 is a partial sectional view schematically showing a cross section taken along line A-A in FIG. 1.

In FIGS. 1 and 2, the base fabric 1 has tufted pile yarns in the back ground section, pile yarns 3 in the pattern section, and pile yarns 4 in the groove section, and the pile yarns 2 in the back ground section and the pile yarns in the pattern section. 3
The tips are trimmed to make the back ground part and the pattern part almost coplanar to form a matte surface. The back ground section pile yarn 2 and the pattern section pile yarn 3 are eventually distinguished by the formation of grooves 6, which will be described later, and are not distinguished before the formation of the grooves 6 and are the same type of pile yarn. Therefore, in a pattern different from that shown in FIG. 1, the back ground pile yarn 2 and the pattern pile yarn 3 may be continuous and cannot be distinguished.

On the back side of the base fabric 1, rubber latex is applied over the entire surface of the base fabric 1 and then vulcanized to form a rubber backing layer 5.

For pile yarns 2 and 3, the number of stitches of the pile yarn per 2.54 cm is S, the gauge number of the pile yarn per 2.54 cm is G, and the fineness of the pile yarn is expressed in denier as D.
Pile yarn density, which is a value expressed by the product of S・G・D, is 8000 to 1280000, preferably 20000 to
Tufted to be in the 300,000 range.
If the pile yarn density is smaller than the above range, the pattern created by forming the grooves will become unclear, and if it is larger than the above range, it will be difficult to form the grooves.

A part of the back ground pile yarn 2 and/or the pattern pile yarn 3 is trimmed to become a groove pile yarn 4 to form a groove 6. In the groove 6, only the pile yarn forming one side of the groove 6 is pruned, and only one side of the groove 6 is formed by the groove pile yarn 4, and the side opposite to the groove 6 is a background pile yarn that is not trimmed. It is formed by thread 2. Furthermore, the groove pile yarn 4 is shortest at a portion close to the side surface of the groove 6 formed by the back ground pile yarn 2, and longest at the open end of the groove 6. The side surfaces of the grooves 6 thus formed are trimmed so as to be inclined with respect to the surface of the base fabric. Maximum depth h of groove 6
is 30% of the length L from the base fabric surface of the pile yarn 3 in the pattern section
It is preferable that the width W of the opening end of the groove 6 is equal to the length L from the base fabric surface of the pattern pile yarn 3.
It is preferable that it is 0.5 to 2 times that of . Further, the side surfaces of the grooves 6 formed by the groove pile yarns 4 are preferably gently upwardly convex as shown in FIG. 2, but they may be flat or concave.
It may also be a waveform surface. The maximum depth h and the width W of the opening end of the groove 6 are related to each other,
Since it is also related to the shape of the sloped side surface of the groove 6, it is not appropriate to define it uniquely, but it is desirable to determine it in consideration of the desired pattern, the appearance of the mat, etc. Generally speaking, if the maximum depth h of the groove 6 is smaller than the above range, the contour part will become unclear and the pattern part will become unclear, and if the width W of the opening end of the groove 6 is larger than the above range. Even if the size is small, the pattern becomes unclear.

In the patterned integrated mat of the present invention, the background pile yarns 2, the pattern pile yarns 3, and the groove pile yarns 4 may all be of the same color, or they may be colored in different colors as appropriate. These pile yarns may be colored by tufting them onto the base fabric to match the desired pattern, or by tufting pile yarns of the same color over the entire surface of the base fabric and then coloring them in the desired color before or after forming the grooves. You can. Further, the entire pile yarn tufted to the base fabric may be colored in the same color, or the tip side of the pile yarn may be partially colored in another color without being colored.

As the base fabric 1, a woven fabric or non-woven fabric made of any synthetic fiber such as polyester is used, while as the pile yarns 2 and 3, crimp nylon fiber, crimped nylon fiber,
Synthetic fibers such as vinylon fibers and acrylic fibers, natural fibers such as cotton fibers, or blended fibers of two or more of these fibers are used. The pile length and area weight are
It may be within the range of mats conventionally used for the purpose of dust control (dust prevention, dust removal), and may generally have a pile length of 3 to 40 mm and a basis weight of 300 to 4000 g/m ² .

Rubbers used for bucking include acrylonitrile-butadiene copolymer rubber (NBR), styrene-butadiene copolymer rubber (SBR), chloroprene rubber, butadiene rubber, ethylene-propylene copolymer rubber, and ethylene-propylene-diene copolymer rubber. Examples include polymer rubber, isoprene rubber, isoptylene rubber, polyurethane, and the like.
These rubbers are applied in the form of latex to the entire back surface of the base fabric 1, dried, and then vulcanized to form a rubber backing layer.

Furthermore, if necessary, on the rubber backing layer, an unvulcanized product formed by blending a vulcanizing agent, a vulcanization accelerator, a pigment, a reinforcing agent, an extender, etc. known per se with the rubber as exemplified above. A rubber sheet is attached and vulcanized and cured, but alternatively, a rubber sheet obtained by vulcanizing and curing the above-mentioned unvulcanized rubber sheet alone can also be attached.

The grooves 6 having the above-mentioned shape are formed in a pattern matching the outline of a desired pattern on the thus formed dusting mat whose entire mat surface is planar and has no pattern.

As a method for forming the groove 6, for example, the following method can be adopted.

That is, the pile yarn is cut using a carving machine, the main part of which is shown in FIGS. 3 and 4, and grooves 6 of a desired shape are formed in a pattern that matches the outline of the desired design. let

FIG. 3 is a front view of a pile yarn cutting portion of one example of the carving machine, and FIG. 4 is a side view of the same portion.

In FIGS. 3 and 4, a fixed blade holder 52 is fixed to the cutting machine holder 51 with bolts 53, and a fixed blade 54 is attached to the fixed blade holder 52.
is fixed at an angle in the axial direction. Fixed blade 54
A movable blade 55 is rotatably attached to the fixed blade stand 52 by bolts 56 above. Movable blade 5
Reference numeral 5 denotes a presser foot 5 made of an elastic plate which is rotatably attached to the fixed blade stand 52 by bolts 56 and is fixed to the movable blade 55 at the end opposite to the cutting edge of the movable blade 55.
7, it is pressed against the fixed blade 54.
The fixed blade 54 and the movable blade 55 are combined to form scissors. The movable blade 55 is rotatably attached to one end of the rod 59 by a bolt 58 together with a presser foot 57 at the opposite end of the blade. The opposite end of rod 59 is rotatably attached to one end of rod 61 by bolt 60. The opposite end of the rod 61 is rotatably attached to an eccentric portion of the rotating plate 63 by a bolt 62. The rotary plate 63 is a motor (not shown) provided inside the cutting machine stand 51.
Since the movable blade 55, rod 59, and rod 61 are attached in the above structure, the cutting edge of the movable blade 55 can reciprocate as the rotary plate 63 rotates. do. The cutting machine stand 51 is attached to a carving machine main body (not shown), and the cutting machine stand 51 can be freely moved vertically and horizontally by operating the carving machine main body. The tip of the fixed blade 54 is buried in the mat surface of the mat, and by moving the cutting machine table 51 while sliding the movable blade 55, the pile yarn on the mat surface is cut and cut. As a result, a groove having an L-shaped cross section can be formed. By adjusting the amount of embedding of the tip of the fixed blade 54 into the pine surface, the maximum depth of the groove can be adjusted. By using the stand 52, the degree of inclination of the inclined side surface of the groove 6 can be adjusted.

Furthermore, by incorporating a computer having a graphic storage device into the carving machine main body, it is possible to automatically form grooves 6 that match any desired pattern. A groove 6 having a portion where the width and depth of the open end of the groove 6 change depending on the design.
However, by storing the contents in the computer in advance, it is possible to cut the pile yarn by slightly shifting the position, or change the amount of embedding of the blade edge to automatically form the yarn as desired. can.
Of course, it can also be operated manually.

The groove pile yarn 4 forming the groove 6 is shorter than the back ground pile yarn 2 and the pattern pile yarn 3, so the reflectance of light is different, and the outline of the pattern can be clearly distinguished and observed. However, if desired, after forming the grooves 6, the groove pile yarns 4 may be dyed in a color different from that of the background pile yarns to form colored contours.

The pile threads of the patterned dusting mat of the present invention have the effect of adsorbing and holding dust adhering to the soles of shoes etc. onto the pile threads by rubbing against the soles of shoes. In order to further enhance the dust adsorption and retention effect of the pile yarns, the pile yarns can be coated with or impregnated with a dust-adsorbing liquid. Examples of such a dust-adsorbing liquid include liquid paraffin,
Mineral oils, synthetic oils, or vegetable oils such as spindle oil, alkylbenzene oil, diester oil, and castor oil, as well as water-based dust adsorbents described in Japanese Patent Publication Nos. 53-10194 and 53-37471, may be mentioned. can.
