Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a three-dimensional patterned foil yarn original fabric, and more particularly to a method for producing a three-dimensional patterned foil yarn original fabric in which the three-dimensional pattern exposed portion is present in the inner layer and the three-dimensional pattern is developed on the outer surface. Regarding

Since such a three-dimensional pattern of the foil thread fabric is expressed on the outer surface by the bulge of the foil thread fabric due to the three-dimensional pattern exposed portion existing in the inner layer portion, it has a rounded shape without edges. is doing. Therefore, the foil yarn obtained from such a raw material of the foil yarn is highly useful because it does not get caught in a shuttle or other fine yarn paths when it is woven into a woven fabric as a warp foil or a drawn foil.

[0003]

2. Description of the Related Art Conventionally, in the manufacture of a three-dimensional pattern foil thread fabric of the type described above, in order to allow the three-dimensional pattern exposed portion to exist in the inner layer portion, the raised portion as the three-dimensional pattern exposed portion is coated with resin or the like. Directly, a base material sheet applied to the sheet surface, and a base material sheet with a similar raised portion or without such raised portion,
The side of the bulge is inside and the method of laminating is used. According to this, when the foil yarn raw material is slit into a narrow width that requires the foil yarn to reduce the adhesive area, the peel strength of the raised portion for imparting the three-dimensionality of the pattern decreases. Thus, there is a problem that the three-dimensional pattern portion of the foil yarn has a strong tendency to be delaminated. In particular, when the foamed portion is filled in the raised portion, the peel strength is weaker, which is more inconvenient.

[0004]

The problem to be solved is the above-mentioned problem in the prior art.

That is, an object of the present invention is to develop a method for producing a three-dimensional pattern foil yarn original fabric of the three-dimensional pattern-exposing portion inner layer existence type which has no tendency of delamination even when the three-dimensional pattern-exposing portion is made of a foamed resin. is there.

[0006]

In order to solve the above-mentioned problems, the method for producing a three-dimensional pattern foil yarn original fabric of the present invention is a three-dimensional pattern in which the three-dimensional pattern exposed portion is present in the inner layer and the three-dimensional pattern is developed on the outer surface. A base material having a heat-fusible adhesive layer on one surface and a raised portion in a pattern as the three-dimensional pattern exposed portion on the surface of the adhesive layer in the production of a patterned foil yarn original fabric. Sheet, a base sheet with a heat-fusible adhesive layer on one side, or the base sheet and the base sheet of the former configuration, the heat-fusible adhesive layer is made the inside, heating, It is characterized by pressurizing and heat welding.

[0007]

As described above, in the present invention, the three-dimensional pattern exposed portion is present in the inner layer portion of the original foil yarn, each of them has a heat-fusible adhesive layer on one side, and both or one of them has the heat-meltable adhesive layer. A method of heat-pressing a base sheet and a base sheet having raised portions in a pattern on the surface of the adhesive adhesive layer, with the adhesive layers inside, heating and pressing I am taking it. According to this method, the patterned raised portion, which is the three-dimensional pattern exposed portion, is a laminate formed by heat-sealing the base material sheet and the base material sheet in a form wrapped from the entire periphery with the adhesive layer. The part corresponding to the patterned raised portion of the base sheet is in a state of being bonded to the adhesive layer.

Thus, according to the present invention, even when the three-dimensional pattern exposed portion is made of foamed resin, there is no tendency for delamination,
The three-dimensional pattern appearance part The embodiment of developing a method for manufacturing a three-dimensional pattern foil yarn raw material with an inner layer is achieved.

[0009]

The present invention will now be described with reference to the accompanying drawings which show embodiments of the present invention.

FIG. 1 (A) is a longitudinal sectional view showing an application example of a base sheet according to the present invention in the state of the following heat-welding,
FIG. 1B is a vertical sectional view showing a different application example of the base sheet according to the present invention under the same condition. FIG. 2 is a side view showing an example of heat welding specifications of the base material sheet according to the present invention.

In the figure, reference numeral 1 is a base sheet of a foil yarn, and the base sheet 1 is Japanese paper, plastic film, cloth (for example, artificial fiber cloth such as rayon, synthetic fiber cloth such as nylon and tetron, mixed fiber). A cloth, which is preferably coated with a resin, preferably a highly flexible resin, or wholly or at least impregnated in the surface layer portion thereof, or a cloth and a Japanese paper bonded together can be advantageously applied.

If necessary, an extremely thin heat-resistant plastic film (not shown) is attached as a protective layer on the surface of the base sheet 1 opposite to the heat-fusible adhesive layer 2 described below. To do.

The heat-sealable adhesive layer 2 is provided on one side of the substrate sheet 1.
And a ridge portion 3 is formed in a pattern on the surface of the adhesive layer 2 with an appropriate specification such as by resin coating.
A base sheet 1 and a base sheet 1 having the heat-fusible adhesive layer 2 formed on one side thereof are combined as a set [FIG. 1 (A)], or a base sheet 1 and a base sheet 1 having the same constitution as the former constitution. As a set [FIG. 1 (B)], the side of the heat-fusible adhesive layer 2 is placed inside, and an appropriate heating / pressurizing means, for example, at least one of them is a flexible roll such as rubber (hereinafter abbreviated as rubber roll). Yes) 4 '
Further, at least one of them is passed through the nip of the pinch roll 4 with a built-in heater, and the base material sheets 1 and 1 are heat-welded by the heat melting of the adhesive layer 2.

In FIGS. 1A and 1B, the set of the base material sheets 1 and 1 is shown in a state where the left end portion is heat-welded and the remaining portion is not heat-welded.

A base sheet 1 having a heat-fusible adhesive layer 2 on one side, and a base sheet 1 having a heat-fusible adhesive layer 2 on one side and further having a patterned raised portion 3 on the layer 2. In the case of heat-sealing the pair of No. 1 and No. 2, it is preferable that the base sheet 1 with the patterned raised portion 3 is on the rubber roll 4 ′ side when passing through the nip of the pinch roll 4. By doing so, the effect of developing the three-dimensional pattern 30 described later is more favorable.

When heat-welding a pair of base material sheets 1 and 1 each having a patterned raised portion 3, the patterned raised portions 3 of the base material sheet 1 are placed in mutually different relational positions, The set of substrate sheets may be passed through a pinch roll nip. By doing so, even if the degree of protrusion of the patterned raised portion 3 is large, when both the pinch rolls 4 are rubber rolls, the convex bulge of the raised portion 3 of the base sheet 1 to the outer surface side causes the base sheet. The entire set of 1s and 1s is well balanced.

As a heating means for heat-melting the adhesive layer 2, instead of applying a heater built-in type to the pinch roll 4, an infrared heater 5 arranged at a required position.
May be used.

In this way, the three-dimensional pattern foil yarn original fabric A in which the three-dimensional pattern 30 is developed on the outer surface by the pattern raised portion 3'which is the three-dimensional pattern exposed portion existing in the inner layer portion is obtained.

The obtained three-dimensional pattern 30 of the original foil yarn fabric A is as shown in FIG. 1 (A) when the combination of the base material sheets 1 and 1 has the patterned raised portion 3 only on one base material sheet. When the pattern-shaped raised portions 3 are present on both sides, both sides are developed as shown in FIG. 1 (B).

In the case where the three-dimensional pattern 30 is a single-sided development type foil yarn original fabric, if the pattern raised portion 3 has a different color from the base sheet 1, it can be seen from the backside of the foil yarn original fabric and the commercial value is lowered. It is preferable that the same color as that of the base material sheet is used, and that when the raised portion 3 is coated with a resin, a resin of the same color or colorless is filled.

When it is desired to obtain a foil yarn original fabric A having a three-dimensional pattern 30 on one side, the base sheet 1 having the patterned raised portion 3 is formed.
Even when the pair of base sheets 1 and 1 is passed through the nip of the pinch roll 4 with the one facing the iron roll side of the pinch roll 4, the three-dimensional pattern 30 has the base sheet side without the pattern raised portion 3. Express more strongly.

In the obtained three-dimensional pattern foil yarn original fabric A, the pattern-shaped raised portion 3'which is built in by the welding is wrapped around the entire circumference by the adhesive layer 2. A portion of the base sheet 1 corresponding to the raised portion 3 ′ is kept bonded to the adhesive layer 2. For this reason, even when the patterned raised portion 3 of the base material sheet 1 is made of foamed resin, the foil yarn obtained by slitting the foil yarn original fabric A into a narrow width tends to be delaminated at the three-dimensional pattern. There is no.

A laminated body obtained by integrally heat-bonding the base material sheets 1 and 1 is, if necessary, immediately after exiting the pinch roll 4,
The cooling roll 6 is circulated and cooled.

[0024]

As described above, the present invention is a method for producing a three-dimensional pattern foil yarn original fabric of the three-dimensional pattern exposed portion inner layer type, which has no tendency of delamination even when the three-dimensional pattern exposed portion is made of foamed resin. The manifestation of developing is achieved.
