Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a dust control (dust removal or dust prevention) mat with a pattern. The present invention relates to a mat with a pattern whose pattern is clear even on the bottom and whose state can be stably maintained.

(Prior art and its problems) Conventionally, in order to prevent dust attached to the soles of shoes from being brought indoors, dust-collecting mats have been used at the entrances and entrances of offices, stores, residences, etc. It is installed and 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, and to draw attention to the store.
When the design becomes blurred, the significance of the design is lost, and even though the mat still has sufficient dust control performance, it loses its commercial value and shortens the life of the mat.

(Purpose of the invention) The purpose of the invention is to ensure that even if a dust control mat with a pattern is used under extremely harsh conditions such as repeated rentals, washing and regeneration, the pattern will be clearly displayed and will last forever. To provide a patterned mat whose condition can be stably maintained.

(Structure of the invention) The present invention provides a dust control mat consisting of a base fabric, pile yarns tufted to the base fabric, and a rubber backing layer applied to the back side of the base fabric, in which the pile yarns have a long length. The pile yarn is dyed in multiple colors in the horizontal direction, and a groove is formed by trimming a portion of the pile yarn until a dyed layer of a different color from the dyed layer on the end side of the pile yarn appears, and a groove is formed at the end of the pile yarn. This patterned mat is characterized in that the pattern is formed by a dyed layer on the side and a dyed layer at the bottom of the groove.

(Operation and Effect of the Invention) As described above, the patterned pine of the present invention has pile threads dyed in multiple colors in the length direction, and grooves are formed by trimming a part of the pile threads. At the bottom of this groove, a dyed layer of a different color from the dyed layer on the pile yarn end side appears, and the dyed layer on the pile yarn end side, that is, the surface dyed layer of matte, and the dyed layer on the base fabric side (one color and The design of the matte with the design of this invention is clear, and even under extremely harsh conditions of use such as repeated rentals and washing and reuse, the design remains unchanged. This state can be maintained clearly and stably forever.

In addition, in the patterned mat of the present invention, the pattern is composed only of the pile yarn itself, and the dyed layer on the base fabric side of the pile, which has a color different from the color of the surface dyed layer of the mat, is one part of the pile yarn. The design is created by pruning the area to form grooves, and the synergistic effect of the difference in color and the grooves makes the design even more stable. be.

Therefore, in the patterned mat of the present invention, the pattern does not become blurred or disappear even after being rented, washed and regenerated many times. There is no drawback that the design part becomes meaningless due to 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.

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

FIG. 1 is a plan view showing the pattern portion of one embodiment of the patterned mat of the present invention, and FIG.
FIG. 3 is a partial cross-sectional view schematically showing a cross section taken along line A-A in the figure.

In Figures 1 and 2, the base fabric 1 has a pile yarn 2 and groove pile yarns 3, 3' where a part of the pile yarn 2 is cut, and the tip of the pile yarn 2 is cut off. They are aligned and planar to form a mat surface. 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 4.

Pile yarn 2 is S・G when 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.・
The pile yarn density, which is the value expressed by the product of D, is 8000
It is tufted to a range of 1280,000 to 1280,000, preferably 20,000 to 300,000. 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.

The pile yarn 2 is dyed in two colors in a portion 2' on the side of the base fabric 1 and a portion 2'' on the end side of the pile yarn in its length direction.
The method of dyeing the yarn end part 2″ is as follows:
For example, after tufting white pile yarn to a base fabric and trimming the ends to form a tufted surface, the entire pile yarn 2 is dyed in the color of the base fabric side portion 2', or the base fabric side portion 2' is tufted in advance. The dyed pile yarn is tufted onto a base fabric and the ends are trimmed to form a tufted surface, and then the yarn end side portion 2'' of the pile yarn 2 is tufted with a color different from the base fabric side portion 2', preferably the base fabric. It is possible to adopt a method of dyeing a color darker than the color of the side portion 2'.The color of the yarn end side portion 2'' of the pile yarn 2 is not affected by the color of the base fabric side portion 2'. In order to dye the end portion of the yarn, it is preferable to dye it by textile printing. In addition, as another dyeing method, the entire pile yarn 2 is dyed in the color of the base fabric side portion 2', and the yarn end portion 2'' of the pile yarn is bleached,
A method may be adopted in which the yarn end portion 2'' is dyed in a lighter tone than the base fabric side portion 2'.

In the patterned mat of the present invention, a part of the pile yarn 2 dyed in two colors as described above is
The grooves 5 are formed by cutting until the base fabric side portion appears. The groove 5 has a substantially V-shaped cross section, and the side surface of the groove 5 is connected to the base fabric side portion 2'.
It is composed of a pile yarn 3' consisting of only a pile yarn 3' and a pile yarn 3 in which a part of the yarn end side portion 2'' remains,
The central part 5' of the groove 5 has the color of the base fabric side part 2', and both edge parts 5'' of the groove 5 have the color of the yarn end side part 2'', and the color of the groove 5
Since the groove 5 has a substantially V-shaped cross-sectional shape, the central portion 5' of the groove 5 is not covered by the pile yarn 3 or the pile yarn 2, and is therefore formed by the central portion 5'. The pattern displayed is clear, and the pattern can be stably maintained even when the patterned mat is used for a long period of time.

The cross-sectional shape of the groove 5 has a ratio h/L of the maximum depth h of the groove to the length L of the pile yarn 2 from the base fabric surface of 1.0 to
0.3, and the groove opening angle α is preferably
It is approximately V-shaped with an angle of 45 to 120 degrees, particularly preferably 60 to 90 degrees. Although the inclined portion of the cross-sectional shape of the groove 5 may be linear, it is not necessarily necessary to be linear, and may be an arcuate or wavy curve. Further, the bottom of the groove 5 may be pointed or rounded, and the cross-sectional shape of the groove 5 may be approximately U-shaped. If the cross-sectional shape of the groove 5 is not V-shaped, the angle formed by two straight lines connecting the center point of the bottom of the groove 5 and the opening end of the groove 5 perpendicularly above it is defined as the opening angle α of the groove. . If the above ratio h/L is smaller than 0.3, the contour portion, which is the groove 5, will become unclear, and the pattern portion will also become unclear.

The length p of the end portion 2'' of the pile yarn 2 is generally 20 to 50% of the length L of the pile yarn 2. However, the length p of the end portion 2'' of the pile yarn 2 is The size and shape of the groove 5, the thickness, length and density of the pile yarn 2,
It should be decided comprehensively based on the difference in color, density, etc. between the base fabric side portion 2' and the yarn end side portion 2'' of the pile yarn 2, and the desired pattern.

As the base fabric 1, a woven fabric or a non-woven fabric made of any synthetic fiber such as polyester is used.On the other hand, as the pile yarn 2, synthetic fiber such as crimped nylon fiber, vinylon fiber, acrylic fiber, cotton fiber, etc. Natural fibers or blended fibers of two or more of these are used. The pile length and area weight may be within the range of mats conventionally used for the purpose of dust control (dust prevention, dust removal), and generally may be a pile length of 3 to 40 mm and area weight of 300 to 4000 g/ ^m2 .

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 rubber. Examples include copolymer rubber, isoprene rubber, isobutylene rubber, and polyurethane.
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 may be attached and vulcanized and cured, or a rubber sheet obtained by vulcanizing and curing the above-mentioned unvulcanized rubber sheet alone may be adhered.

The grooves 5 having the shape described above are formed in a pattern corresponding to 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 grooves 5, 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. 4 and 5, and grooves 5 of a desired shape are formed so that the pattern matches the outline of the desired design. let

FIG. 4 is a front view of a pile yarn cutting portion of one example of the carving machine, and FIG. 5 is a side view of the same portion.

4 and 5, a fixed blade stand 52 is fixed to the cutting machine stand 51 with bolts 53, and the fixed blade stand 52 has two fixed blades 54, 54'.
are fixed so that the blade edges are aligned to form a V-shape and the blade surfaces are in the same direction. Fixed blade 54,5
4', movable blades 55, 55' are rotatably attached to a fixed blade stand 52 by bolts 56, 56', respectively. The movable blades 55, 55' are rotatably attached to the fixed blade stand 52 by bolts 56, 56', and are fixed to the movable blades 55, 55' at the ends opposite to the cutting edges of the movable blades 55, 55'. The fixed blade 54,
54'. The fixed blade 54 and the movable blade 55, and the fixed blade 54' and the movable blade 55' are combined to form scissors. Movable blade 5
5, 55' are the presser foot 57, at the opposite end of the cutting edge.
57', the rods 59 and 59' are rotatably attached to one end of the rods 59 and 59' by bolts 58 and 58'. The opposite ends of the rods 59, 59' are
It is rotatably attached to one end of rods 61, 61' by bolts 60, 60'. The opposite ends of the rods 61, 61' are connected to the bolts 62, 6
2', the rotary plates 63, 63' are rotatably attached to eccentric positions. Rotating plate 63,6
3' rotates at a constant speed or at variable speeds by a motor (not shown) provided inside the cutting machine stand 51;
Since the movable blades 55, 55', the rods 59, 59', and the rods 61, 61' are attached in the above structure, the movable blades 55, 55' are rotated as the rotating plates 63, 63' rotate. The cutting edge makes a reciprocating motion. 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. Fixed blade 5
The pile yarn on the mat surface is cut by moving the cutting machine table 51 while sliding the movable blades 55, 55' so that the ends of the mats 4 and 54' are buried in the mat surface of the mat. As a result, a groove having a V-shaped cross-section can be formed. The maximum depth of the groove can be adjusted by adjusting the amount of embedding of the tips of the fixed blades 54, 54' into the mat surface, and the attachment of the fixed blades 54 and 54' of the fixed blade stand 52 can be adjusted. By using fixed blade stands 52 with different angles, the opening angle α of the groove can be adjusted.

Further, by incorporating a computer having a graphic storage device into the carving machine main body, grooves 5 matching any desired pattern can be automatically formed. A groove 5 having a portion where the width and depth of the open end of the groove 5 change depending on the pattern.
However, by storing the contents in advance in the computer, you can cut the pile yarn by slightly shifting the position, or change the amount of embedding of the cutting edge to automatically form it freely. I can do it. Of course, it can also be operated manually.

In addition, the groove 5 in the patterned mat of the present invention
is a groove whose bottom surface is a plane substantially parallel to the base fabric 1, as shown in FIG. Good too. As is clear from the above explanation, the pile yarn 3' forming the bottom surface of the groove 5 is
All have the color of the base fabric side portion of the pile yarn 2.
Although the groove 5 is shown to be approximately rectangular in FIG. 3, it may also be square or inverted trapezoidal with an upward opening. Such grooves can be easily formed by using a clipper-type cutting member instead of the carving machine cutting member as shown in FIGS. 4 and 5, or by using a combination of the two. can do.

The pile threads of the patterned pine according to the present invention have the effect of adsorbing and holding dust adhering to the soles of shoes etc. on the pile threads by rubbing against the soles of shoes. In order to further enhance the dust adsorption and retention effect of the pile yarn, the pile yarn can be coated or impregnated with a dust-adsorbing liquid. Such dust-absorbing liquids include, for example, liquid paraffin, spindle oil, alkylbenzene oil, diester oil, mineral oil such as castor oil, synthetic oil, vegetable oil-based oils, and Japanese Patent Publication Nos. 53-10194 and 53-37471. Examples include aqueous dust adsorbents described in publications.
