DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4 showing an example of a pile material manufacturing process of the present invention. Note that FIGS. 1 to 4
In particular, this is an example for efficiently producing an elongated tape-shaped pile material 2. The pile fabric 3 is formed by forming a plurality of rows in which pile yarns 6 are planted on one base cloth 4. The drawing shows a step of forming the pile material 2 including the fixing portion 10 and the extruded layer 12 and then cutting the pile material for each pile row to obtain a tape-shaped pile material.

The pile material 2 of the present invention is, for example, shown in FIG.
As shown in (c), the pile fabric 3 formed by the base cloth 4, the pile yarn 6 planted on the base cloth 4, the pile yarn fixing portion 10, and the extrusion molding for coating the back surface of the base cloth 4. And a layer 12. The base fabric 4 of the pile material 3 used in the pile material 2 of the present invention can be used without any particular limitation on the material. However, the extruded layer 1
In view of the relationship with the resin forming the resin layer 2, it is necessary to form the resin layer with a resin fiber compatible with the resin used for the extrusion molding layer 12. For example, when a PP-based resin is selected as the material of the extruded layer, the fibers forming the base fabric 4 are:
Select a resin fiber compatible with the PP resin. In this case, examples of the resin fibers compatible with the PP resin include olefin fibers. Preferably, it is a PP fiber.

The pile yarn 6 can be used without any particular limitation on its material. As the pile yarn 6, it is preferable to use a polyamide-based fiber, a polyester-based fiber, an acrylic-based fiber, or the like having good wear resistance and resilience.
The material of the pile yarn 6 may be one type, or two or more types may be used in combination. In particular, the pile yarn 6 made of polyamide fiber is excellent in resilience and durability, so that the pile material is used as an airtight material for aluminum sashes, screen doors and shutters, or as a pile material for a brush material of a suction port of a vacuum cleaner. Suitable as a yarn. Also, the thickness of the pile yarn 6 can be used without any particular limitation. Pile yarn 6
Are planted in a bundle in the base cloth 4 by a conventionally known method. Basically, the pile 4 is planted so that a bundle of pile yarns 6 is hooked on the yarn (ground yarn) 4 a (weft yarn) constituting the base fabric 4. Therefore, the pile yarn 6
The planting base 8 is formed in a loop shape on the back surface (the surface on which the pile yarn is not raised) of the base cloth 4.

Thus, the pile fabric 3 is formed from the base cloth 4 and the pile yarn 8. The pile yarns 6 are usually planted in the pile fabric 3 at a uniform density on the surface of the base cloth 4. However, the pile material 2 to be obtained
The state of planting of the pile yarn 6 can be changed depending on the mode. For efficient production of the pile material, as shown in FIG. 2, if the pile material 2 to be obtained is an elongated tape, as shown in FIG. The pile yarns 6 can be planted in a line on the surface of the base cloth 4 so that a plurality of tape-shaped pile materials 2 can be obtained by cutting in the process.

A pile thread planting base 8 is formed on the surface of the pile fabric 3 thus formed on the side where the pile thread 6 is not raised. In order to form the pile thread fixing portion 10 on the pile thread planting base 8, an adhesive is applied to the pile thread planting base 8, and the pile thread planting base 8 is adhered and solidified in a bundle, or At the same time as the solidification, the pile yarn 6 is bonded and fixed to the base cloth 4 (see FIG. 1B). According to the pile yarn fixing portion 10, the pile yarn 6 can be fixed to the base cloth 4 irrespective of compatibility with the extruded layer 12. In order to effectively solidify and prevent the pile yarn planting base 8 from coming off, it is preferable to use an adhesive compatible with the pile yarn 6. Further, preferably, in addition to the compatibility with the pile yarn 6, the compatibility with the base fabric 4 and / or the compatibility with the extruded layer 12 is provided. When the adhesive has compatibility with the base cloth 4, the pile yarn planting base 8 is satisfactorily integrated with the base cloth 4 by the pile yarn fixing portion 10, and the adhesive is compatible with the extruded layer 12. If so, the pile yarn anchoring section 10 causes the pile yarn planting base 8 to be extruded.
It is well integrated. If the adhesive has compatibility with the base cloth 4 and the extrusion molding phase 12, the pile yarn fixing portion 1
With 0, the pile yarn planting base 8 is well integrated into both the base cloth 4 and the extruded phase 12. For example, when the pile yarn 6 is a polyamide fiber, the base cloth 4 is a PP fiber, and the extruded layer 12 is a PP resin,
The adhesive preferably has compatibility with the polyamide fiber, and more preferably has compatibility with the polyamide resin fiber and compatibility with the PP resin. In this case, the pile yarn fixing section 10 is favorably integrated with any of the pile yarn 6, the base cloth 4, and the extruded layer 12.

Examples of the adhesive for forming the pile thread fixing section 10 include acrylic, urethane, synthetic rubber, reactive synthetic resin, chlorinated polyethylene, chlorinated PP, and adhesive polyolefin. A system or the like can be used.

In order to apply the adhesive to the pile yarn planting base 8, various ordinary methods for applying an adhesive can be used. For example, the nozzle N for discharging the adhesive is moved on the fixed pile ground 3 to apply the adhesive to a necessary portion, or as shown in FIG. To fix the nozzle N and apply the adhesive in a line along the line-shaped pile yarn planting base 8. In the present invention, an adhesive may be selectively applied to the planting base 8,
The adhesive may be applied to a wider portion including the planting base 8, and furthermore, the adhesive may be applied to the entire surface of the base cloth 4 on the side where the planting base 8 is located. Further, in order to make the adhesive penetrate the pile yarn 6 quickly, it is preferable that the viscosity of the adhesive is 5 cps or more and 100 cps or less. If the viscosity is in this range, the pile yarn planting base 8
And then quickly penetrates the pile yarn 6. In addition, since the adhesive is quickly solidified, the extruded layer 12 can be stacked without any time.

Next, as shown in FIG. 1C, an extruded layer 12 is formed to cover the side of the base cloth 4 where the pile yarn planting base 8 is located. As the resin of the extruded layer 12,
A resin compatible with the base cloth 4 is selected. Thus, the extruded resin is satisfactorily integrated with the base cloth 4. Also,
The rigidity of the extruded layer 12 is favorably imparted to the pile material 2. Further, the extruded layer 12 preferably has compatibility with the adhesive. By providing such compatibility, the pile yarn fixing portion 10 can be satisfactorily integrated with the extruded layer 12. When the extruded layer 12 is formed, as shown in FIG. 4, just below the extrusion port P, the planting base side of the pile is placed at a speed corresponding to the extrusion speed of the resin layer extruded from the extrusion port P of the extruder. Move along the extrusion direction. Thereafter, the pile material 3 on which the extruded layer 12 is superimposed is pressed by a roller or the like to be integrated.

The pile material 2 having the extruded layer 12 formed thereon is prevented from coming off the pile yarn 6 by the pile thread fixing portion 10 and has a good integration with the base fabric 4. The rigidity is given to the base fabric side of the pile material 2. Since the pile material thus formed has rigidity on the base fabric side, the mounting workability is good. Also,
Since the pile yarn 6 is fixed by the pile yarn fixing portion 10 irrespective of the extrusion molding phase 12, the pile molding layer 1
The desired material is selected irrespective of the compatibility with the material constituting 2. Therefore, it is possible to provide an airtight material for an aluminum sash or a screen door, or a brush material for a vacuum cleaner.
