JPS60239575A - Production of water-permeating artificial lawn - Google Patents

Abstract

PURPOSE:A pile-type artificial lawn is coated with a plastic sol on its back surface and air is blown from the fore surface through to the back surface, before the solve hardens into gel to make through-holes on the sol clogging the meshes of the base, thus giving the titled artificial lawn. CONSTITUTION:The base cloth is piled with strings and coated with a plastic sol 3 on its back face. Then, before the sol becomes hard, air is sent at a rate, e.g., of 1-5m<3>/min from the front surface through to the back surface B to bore through-holes on the plastic sol clogging the knit or weaving meshes 3a, then the sol is gelatinized. The blown sol comes to the back surface so that it remains under the gel coating of the yarns to prevent the pile-falling.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing water-permeable artificial turf that is mainly laid outdoors, and particularly to a method for forming permeable channels.

(Prior art) Conventionally, artificial turf mainly used outdoors has been made by planting piles on a base fabric made of knitted or woven fabric, etc. Because it slips through the base fabric,
In order to fix Nosoil to the base fabric during the manufacturing process, plastic or rubber was generally applied.

However, the application of such a fixing material closes the stitches or textures of the base fabric, and as a result, the water permeability of artificial turf is significantly inhibited, so there has been a strong demand for countermeasures against this problem.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned circumstances.
Water-permeable artificial turf that fully achieves the purpose of preventing the tile from slipping through the base fabric, and has been devised to ensure the water permeability of artificial turf, which was previously inhibited by coating to prevent this. The present invention provides a method for manufacturing.

(Means for Solving the Problems) The method of the present invention provides a method of applying plastic resin to a predetermined thickness on the back side of an artificial turf material made by planting piles on a base fabric. + expression ≧

Air was blown from the front side to the back side of the Akane P original fabric to create perforations in the plastic sol that blocked the stitches or textures of the base fabric. Later, the sol is turned into a cell and perforations are formed in permeable channels to produce water-permeable artificial turf.

(Function) In the present invention, the plastic sol is applied to the back side of the raw fabric for artificial turf to a predetermined thickness, and air is blown from the front side of the raw fabric toward the back side. This method creates perforations in the sol covering the cross stitches or weaves, and blows air while the sol is flexible and does not become glued.
The amount of sol equivalent to the size of the holes moves to the bottom of the sol attached to the yarn, further helping to prevent the pile from being removed. It can increase the strength.

(Example) 1 The present invention will be described below based on an example with reference to the drawings.

FIG. 1 is a partial perspective view showing an example of a raw material for artificial turf 01 to which the present invention is applied. Normally, a plain woven fabric is often used as the base fabric 1, but other woven or knitted fabrics may also be used. A U-shaped /4' tile 2 is planted on the base fabric 1. FIG. 1 (11) is a schematic cross-sectional view of such a raw fabric. The pile 2 is supported by the warp or weft threads of the base fabric, but is not fixed to these threads.
It is planted on both the front and back sides of the base fabric so that it can be easily removed by pulling it by hand. For this reason, many efforts have been made to prevent this from happening.

Of these, the most frequently used method was to coat the back side 1a of the original fabric shown in No. 2 [9 (i) with Plasti and Kusol 3 to a predetermined thickness, as shown in (11) of the same figure. Layered pile 2
This is a method for preventing the film from slipping through, and methods such as pasting using a roll or dipping in a sol have been used for this application. However, even if this can prevent slippage, at the same time, the plastic sol covers the weave or stitch of the base fabric, and as a result, the first stitch of the weave is blocked and the water permeability of the artificial turf is lost. It was supposed to be punished.

In the present invention, after applying the plastic sol 3 to a predetermined thickness on the back side of the original fabric as shown in Fig. 2 (ii+), while the sol is still flexible without being glued, ), air is blown from the front side A to the back side B of the original fabric using a blower at a rate of, for example, 1 to 5 m3/min, and the stitches of the base fabric that are in contact with the air relatively strongly or After forming perforations 3a in the plastic sol covering the weave, the sol is glued and the perforations 3a are formed into permeable channels to obtain a water-permeable artificial turf material.In this case, the perforations are The dulls 3b in an amount equivalent to the size of the piles move around under the glue attached to the yarn, and the removal of the pile further facilitates prevention. ), when an elastic backing material 4 such as foamed plastic is attached, the binding strength is increased.

(Effects of the Invention) In this manner, the manufactured artificial turf material has the grooves 5, so that an artificial turf having extremely good drainage can be obtained.

Claims (1)

[Claims] A plastic sol is applied to a predetermined thickness on the back side of an artificial turf material made of a base fabric with piles planted on it, and while the sol is flexible and does not become a keratin, it is applied from the front side of the material material. Permeable artificial turf is produced by blowing air toward the back side to create perforations in the silastic sol that blocks the stitches or textures of the base fabric, and then dulling the sol to form perforations into permeable channels.
