Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a patterned dusting (dust removal or dust prevention) mat, and more specifically, the present invention relates to a dusting (dust removal or dust prevention) mat with a pattern. The present invention also relates to a dusting mat with a pattern that has a clear pattern and can stably maintain its state.

(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 installed at the entrances and entrances of offices, stores, residences, etc. etc., and are used. Some mats of this type have designs such as letters, pictures, marks, etc. on the surface that are separated by color from the background. While this patterned mat is repeatedly washed and reused, the pile yarns in the background area and the pile yarns in the pattern area become entangled with each other in the boundary area between the background area and the pattern area. 1. Since the colors of the two threads are different, the color of the boundary area is 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 contour portion is tufted with pile yarn of a different color from the pile yarn of the background portion, or
The contour portion is formed by dyeing the pile yarns in the contour portion in different colors, and further by electrostatically flocking fiber flows 2 of different colors onto the contour portion. however,
Even if the contours are formed by such a method, there is a drawback that the contours become unclear and the design gradually becomes blurred during use of the mat.

The purpose of putting a pattern on a dusting mat is to give an impression of the store where the mat was installed to people passing by the market.
Since the purpose is to promote the store or to attract attention, if one pattern becomes blurred, the purpose of including the pattern is lost, even though the dusting performance is still sufficient.

This results in loss of commercial value and shortens the lifespan of the mat.

(Objective of the Invention) The object of the present invention is to ensure that even if a dusting mat with a pattern is used under extremely harsh conditions such as being repeatedly rented, washed and regenerated, the pattern will be clearly displayed and will last forever. To provide a dusting mat with a pattern whose condition can be stably maintained.

(Structure of the Invention) The present invention provides a dusting mat comprising a base fabric, pile yarns that are tufted into the base fabric and trimmed on a substantially flat surface, and a rubber parking layer applied to the back surface of the base fabric. In this case, the pile yarn in the base fabric is S, where the number of stitches per 2.54 cm is S, the gauge number of 2.54 cm dust is G, and the fineness of the pile yarn is D (denier). - Pile yarn density expressed as the product of G and D is 5o
By trimming a part of the pile threads on the surface of the mat, it has a substantially V-shaped cross-sectional shape, and the maximum depth of the groove/base fabric surface This dusting mat with a pattern is characterized in that grooves are formed such that the ratio of the lengths of the pile yarns is in the range of 1.0 to 0.3, and the pattern is formed by the grooves.

(Operations and Effects of the Invention) As described above, the patterned dusting mat of the present invention has pile yarns tufted with a pile yarn density within a specific range, and grooves of a specific shape are formed on the mat surface as the outline of the pattern. Since the pattern is formed by the grooves,
Even though the pile threads in the contour area are the same color and the same quality as the pile threads in the background and pattern areas, when observed from a distance, such as when the mat is being laid down, the contour areas are different from the pattern areas. appears to be a different color tone, the pattern area is clearly distinguished from the background area, and even after the mat has been trampled on by many people, and even after repeated cleaning and reprocessing of the mat. , the outline part does not disappear and the pattern part and the background part are clearly distinguished.

Therefore, in the guesting mat of the present invention, the design part does not become blurred or disappear even after being rented, washed and regenerated many times. Therefore, there is no point in providing the design part, and there is no disadvantage of shortening the product life.
The effect is that the product life of the patterned mat can be stably maintained up to the limit of the physical life of the mat.

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

FIG. 1 is a partial sectional view schematically showing a groove portion (outline portion) of an embodiment of the patterned dusting mat of the present invention. In FIG.

Is there pile thread in the background part of the base fabric L? , the pattern section pile yarn 3 and the groove section pile yarn 4 are tufted at the following pile yarn density. These pile yarns 2.3 and 4 are all of the same color and quality, and are all tactified with the same pile yarn density. The ends of the background section pile yarn 2 and the pattern section pile yarn 3 are trimmed so that the background section and the pattern section are substantially on the same plane to form a matte surface. The pile yarn density of each pile yarn above is indicated by the number of stitches of the pile yarn per 2.54 cm in S, the gauge number of the pile yarn at 2.54 cm in G, and the fineness of the pile yarn in denier units. is the value expressed by the product of S・G−D, and the pile yarn density is 8000 to 1280000.
, preferably in the range of 20,000 to 300,000. If the pile yarn density is less than 5ooo, the outline of the pattern created by groove formation becomes unclear, and if it is greater than 1,280,000, it becomes difficult to form grooves.

Rubber latex is applied to the entire surface of the base fabric 1 and then vulcanized to form a rubber backing layer 5 on the back surface of the base fabric 1.

At the boundary between the background part and the pattern part, a groove 6 having a substantially ■-shaped cross-section is formed by trimming a part of the pile yarn, and the pattern is constructed using the groove 6 as the outline part. . The cross-sectional shape of the groove 6 has a ratio h/L of the maximum depth h of the groove and the length L of the pile yarn 2 (3) from the base fabric surface to 1.
．． The opening angle α of the groove is preferably 45 to 120 degrees, particularly preferably 60 to 90 degrees. Although the sloped portion of the cross-sectional shape of the groove 6 may be linear, it does not necessarily have to be linear, and may be an arcuate or wavy curve. Also, the bottom of the groove 6 may be pointed or rounded,
The cross-sectional shape of the groove 6 may be close to a U-shape. If the cross-sectional shape of the groove 6 is not a 7-shape, there are two wires connecting the bottom center point of the groove 6 and the open end of the groove 6 vertically above it. Let the angle formed by the straight line be the opening angle α of the groove. The above ratio h
If /L is smaller than 0.3, the contour portion, which is full 6, will become unclear, and the pattern portion will also become unclear. Furthermore, if the opening angle α of the groove is smaller than 45 degrees, the outline will become unclear, and if the angle α is larger than 120 degrees, the outline will become too thick, and the background part and pattern part will become integrated. They tend to lose their sexuality and become unsightly.

As the base fabric 1, a woven fabric or non-woven fabric made of any synthetic material such as polyester is used, while as the pile yarns 2 and 3, synthetic fibers such as crimped nylon U&F, vinylon fiber, acrylic fiber, etc. are used. , natural M fiber such as cotton MRA, or a blend of two or more of these #A fibers. 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 the pile length is 3 to 40 mm and the mat weight is 300 to 4000 mm.
The basis weight may be g/m2.

Rubbers used for the backing include acrylonitrile-butadiene copolymer rubber (NBR), styrene-
Examples include butadiene copolymer rubber (SBR), chloroprene rubber, butadiene rubber, ethylene-propylene copolymer rubber, ethylene-propylene-diene copolymer rubber, invrene rubber, inbutylene 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 rubber sheet formed by blending a known vulcanizing agent, vulcanization accelerator, pigment, reinforcing agent, extender, etc. with the rubber as exemplified above is attached and cured by vulcanization, or It is also possible to adhere a rubber sheet obtained by vulcanizing and hardening an unvulcanized rubber sheet.

Grooves 6 having the above-mentioned shape are formed in a pattern matching the outline of a desired pattern on the pattern-free dusting mat whose entire mat surface is planar.

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 carping base whose main part is shown in FIGS. 2 and 3, and grooves 6 of a desired shape are formed so that the pattern matches the outline of the desired design. let

is attached to a carping machine main body (not shown), and the cutting machine stand 51 can be freely moved vertically and horizontally by operating the carping machine main body. The tips of the fixed blades 54, 54' are buried in the mat surface of the mat, and the pile yarn on the mat surface is cut by moving the cutting machine table 51 while sliding the movable blades 55, 55'. As a result, a groove having a figure-7 cross-sectional shape can be formed. Fixed blade 54゜5
The maximum depth of the groove can be adjusted by adjusting the amount of embedding of the tip of the blade 4' into the mat surface. By using the fixed blade stand 52, the opening angle α of the groove can be adjusted.

In addition, by incorporating a computer with a figure storage device into the carping machine body, it is possible to automatically form grooves 6 that match any desired pattern. Even if the groove 6 has a part where the depth changes, 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. It can be freely formed automatically.

Of course, it can also be operated manually.

The groove pile yarn 4 forming the groove 6 is shorter in length than the background pile yarn 2 and the pattern pile yarn 3, and has a pile yarn density within a specific range.
Although the light reflectance is different and the outline of the pattern can be clearly distinguished and explained, if desired, after forming the grooves 6, the groove pile yarn 4 may be dyed in a different color from the background pile yarn. , it is also possible to form colored contours.

The pile yarn of the patterned dusting mat of the present invention has the function of adsorbing and retaining dust adhering to the sole of the shoe by rubbing against the sole of the shoe. To further enhance the effect, the pile yarns can be coated or impregnated with a dust-absorbing liquid. Examples of such dust-absorbing liquids include liquid paraffin, spindle oil, alkylbenzene oil, diester oil, mineral oil such as castor oil, synthetic oil, vegetable oil, and Japanese Patent Publications Nos. 53-10194 and 53-37471.
Examples include the aqueous dust adsorbent described in Japanese Patent No.
