Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a tiled carpet and a one-time method for processing the same.

BACKGROUND ART In recent years, for carpets to be laid on the floor, it has been considered to cut the carpet into predetermined sizes and arrange them on the floor to form tiles.

Carpet tiles have the advantage that they are more convenient to transport than long carpets, and at the same time, they can be partially replaced in the event of damage during use, and they can be delivered in different colors. .

The carpet has a one-piece structure with a pile direction provided on the surface 101 of the base member, and a tile-shaped carpet is cut into a predetermined size from such a long carpet.

By the way, in cases where the surface pile surface is formed by loops, the parallel direction of the tile-like carpet and the loops may not necessarily be parallel to each other. It may be necessary to cut diagonally at the rising edge of the loop.

As shown above, when one end of the rising part of the loop is cut and cut diagonally, the twist of the yarn forming the loop returns from the cut end, forming a 16-shape. .

In this way, when the cut end of the raw yarn at the pile surface Q becomes cotton-like due to untwisting, the friction resistance strength around the surface of the tile-like carpet decreases significantly. Reasons why carpets fall off: If the yarn is untwisted at the cutting point, the edges of the tile-like carpet will become fluffy, significantly reducing its commercial value.

This invention was made in view of the above problems.
This is a small piece, cut out from a long and wide carpet 7':
A tile-shaped carpet that does not untwist the raw yarn at the edge of the pile surface of the tile-shaped carpet, has strong friction resistance at the edge of the pile surface, and can significantly improve the product value, and efficiently manufacture this carpet. The purpose is to provide a processing method that can be used.

The structure of the present invention is to cut the carpet into predetermined dimensions, apply heat and pressure to the periphery of the pile surface, and indent the cut end of the pile surface in a linear Q shape along the outer periphery. The part is fixed to the base part.

The present invention will be explained below based on the attached Example Q.

Fig. 1 shows an example of the cross-sectional shape of a tile-like carpet 1 cut out from a long and wide carpet to a predetermined size and shape. Form the surface Q of the base fabric 2 and the back base fabric 6.
In this order, 411t is formed.

The base member 5 is made of heat-melting material such as asphalt, coal tar, synthetic rubber, vinyl chloride, synthetic resin, etc.
The loop 3 is held firmly by adhesion to the back side of the base fabric 2,
Increases stability when laying tile carpet.
Therefore, it is preferable to form it relatively thickly.

The horizontal size and shape of the tile-like carpet 1 are, for example, 50 crn x 50 cm, 30 crn 1 x 30 cm.
The basic shape is a square like the letter M, but you can choose any shape you want, such as the shape you wear or the shape of a diamond.

However, the formation of the pile surface 4 is not limited to that shown in the drawings, but can be done by omitting the use of the base fabric 2 and directly embedding the lower part of the loop 3 into the base member 5 and hardening it. In addition to fixing with an adhesive, the pile surface 4 may be formed by needle punching using cut pile or nonwoven fabric.

A tile-shaped carpet cut into a specified size and shape)
1+ heat pressurization is applied along the cut periphery of 1 pile and 4 at an appropriate width, and as shown in FIG. form.

As shown in the figure, the pile surface 4 is shaped into a loop. In this case, the rising part at the cut edge of the roof yarn is
The upper surface (this part is compressed under pressure, and the part that receives this compression is heated (this melting M!l!L). This melted part 8 becomes flat and is heated from above the base fabric 2 to the base member 5 & this melting layer. In the case of a carpet without a base fabric, the base member 5 is directly molded.

The melting section 8 of the loop yarn has a heating temperature, a pressing force, and
The deformation of the loop thread count can be freely selected depending on the material used, and it is sufficient to deform it so that at least the cut end of the loop 3 is fixed on the base fabric 2 and does not become fuzzed.

By applying heat and pressure along the periphery of the 4 sides of the pile, the tile-like carpet I-IIL is finished in a single shape with the periphery of the pile face 4 surrounded by linear recesses 7, as shown in FIG.

In this recessed part 7, tiled carpets 1 are laid side by side.
In this case, it appears as an eye-like pattern on the base and forms a new pattern when it is laid.The width of the recessed part 7 can be selected arbitrarily, but it is formed to a width of about 145 mm, for example. is preferable.

As the means for heating and pressurizing the pile surface 4, in addition to a heater, high frequency heating or the like can be used.

As described above, according to the present invention, since it has the configuration as shown in "-", it has the following effects.

(1) The pile surface Q of the carpet was cut into a desired shape, and a pile concave portion was formed along the outer peripheral edge Q by heating and pressing. It can be deformed under pressure and placed on the base member, and no matter how the end of the pile surface is cut, the twist of the yarn will not come back from the cut end, and the cutting v ; The M part is no longer +MiS-like Q fluffy.

(2) Since the periphery of the pile surface is free of cotton-like fuzz, the tile-like carpet has a beautiful finish, and the product value can be greatly improved.

(31) Since the periphery of the pile surface is fixed on the base member, the +1liJ friction strength around the pile surface is increased.
2, 1++ Jkyu 1 improves 1:.

(41) Since the cut edge of the pile surface is fixed to the base part by heating and pressurizing, there is no occurrence of suture removal from the cut end of the pile yarn.

(51) Since the cutting edge of the pile surface is heated and pressurized by four people, even if the pile surface is formed into a loop, cutting can be performed regardless of the direction or arrangement of the loop.

(61) Since the recessed part surrounds the pile blood periphery of the tile-shaped carpet in a frame shape, the recessed part forms the base 1 when used for laying. It is possible to express a pattern of feelings.

(7) Since it is only necessary to heat and press the periphery of the pile surface, processing is extremely simple, and tubular products with commercial value can be produced efficiently.
