Description

[Detailed description of the invention] Ru.

Conventionally, adhesive is printed in a pattern on washi paper using a gravure cylinder, etc., and then transfer foil, which has a vapor-deposited layer on gold but does not have an adhesive layer, is layered and transferred. It is known to prepare a strip to which a vapor-deposited layer is attached, and then slit it to insert gold and silver threads. It is also known that printing paste is printed in a pattern on a fabric, a metal vapor-deposited layer is attached to the patterned part of the printing paste in the same way as described above to form a band, and this is slit to cover with gold and silver thread. ing.

However, in the case of conventional patterned gold and silver thread, it is necessary to apply adhesive or printing paste in a pattern to Japanese paper or textiles.
This requires a gravure printing machine or a textile printing machine, which increases equipment costs.

Another problem is that it is difficult to change the delicate contrasting metallic luster pattern.

In view of the above-mentioned points, the present invention provides a patterned gold and silver thread having a metallic luster pattern with delicate contrast without requiring a step of applying adhesive or printing paste in a pattern.

That is, the present invention provides a belt-like article having a structure in which a coarse nonwoven fiber aggregate is thermally fused onto at least one side of a flexible base material, and a metal vapor-deposited layer is adhered to the fibers of the fiber aggregate. The present invention provides a patterned gold and silver thread which is a slit thread with a ratio of 9':l-.

Furthermore, the present invention provides a method in which a nonwoven fiber aggregate with a coarse texture and a transfer foil having a metal vapor deposited layer but not an adhesive layer are stacked in this order on at least one side of a flexible base material, and heated. A pattern characterized in that a fiber aggregate is heat-sealed onto a flexible base material by pressing, and a band-like product is formed in which a metal vapor-deposited layer is adhered to the fibers of the fiber aggregate, and then this is slit. The present invention provides a method for manufacturing gold and silver threads.

Next, the patterned gold and silver thread of the present invention will be explained based on the drawings. FIG. 1 is a partial plan view showing one embodiment of the patterned gold and silver thread of the present invention, and FIG. 2 is a partial enlarged sectional view thereof.

The gold and silver thread shown in Figures 1 and 2 has a coarse nonwoven fiber aggregate (2) heat-sealed on one side of a flexible base material (1), and the aggregate (2) is It has 6 configurations, in which a band-like material made of fibers (8) and a metal vapor-deposited layer (4) attached thereto is slit. (5) shows each Ht fiber (a) to which the metal vapor deposited layer (4) is attached.

The fiber (3), which originally had a substantially circular cross-sectional shape, becomes substantially rectangular due to heating and pressure during heat fusion, and the metal vapor deposited layer (4) is attached to the flat surface of the fiber (8). Excellent metallic luster.

In the patterned gold and silver thread of the present invention, the metal vapor deposition layer (4) is attached to each fiber of the nonwoven fabric-like fiber aggregate (2) with a coarse structure that is heat-sealed onto the base material (1). The aggregation of fibers (5) having such a metal vapor-deposited layer gives a unique metallic luster pattern with a disordered yet delicate contrast.

Furthermore, in the present invention, instead of applying adhesive or printing paste in a pattern on the base material as in the past, the nonwoven fiber aggregate (2) is simply layered on the base material (1) and thermally fused. This forms a pattern to which the metal vapor deposited layer (4) is attached, making it extremely easy to form a metallic luster pattern.

In the present invention, a flexible base material (1
) The fiber aggregates (2) may be heat-sealed on both sides of the fiber aggregate (2), and a number of post-arc vapor deposition layers (4) may be applied thereto to form a metallic luster pattern on both sides. Also, as shown in Figure 4,
A flexible base material (1') is formed by laminating a flexible base material (1) with an adhesive layer (6) interposed therebetween, and the gold h'↓ is coated on both sides of the flexible base material (1').
It is also possible to make the gloss inspection pattern clearer. Patterned gold and silver threads having such a structure are usually produced by preparing in advance a strip having a cross-sectional structure as shown in FIG. 2, and slitting the two-ply structure.

In addition, in order to improve the durability of the metal vapor deposited layer (4), an uncolored or colored transparent top is applied to the entire surface of the flexible base material (1) having the fiber aggregate (2) to which the metal vapor deposited layer (4) is attached. It is also possible to have a configuration in which a strip-shaped article provided with a coating layer is slit.

As the flexible base material (1), synthetic resin films, papers, woven fabrics, laminates thereof, etc. are used. As the synthetic resin film, any usual film such as polyester, acrylic resin, polyvinyl chloride, polyethylene, polyethylene, etc. can be used, and the thickness is about 2 to 100 μm.

Japanese paper, Western paper, synthetic paper, etc. are all used as paper, and the tsubo is 8 to 80 degrees. /rn2 is used. In particular, Japanese paper for gold and silver threads is preferably used. Woven fabrics include ordinary synthetic fiber cloth such as polyester fiber cloth, acrylic fiber cloth, rayon fiber cloth, vinylon fiber cloth, cotton cloth, etc.
Both semi-synthetic fiber cloth and natural fiber cloth can be used.

In the case of paper, one coated with a sealing resin may be used. As the flexible base material (1), a base material as described above with a metal vapor deposited layer provided on one or both sides thereof may be used.

The nonwoven fiber aggregate (2) is made of polyamide (for example, nylon-6, nylon-66, etc.) FlI fiber, polyolefin-modified polyamide fiber, polyester X +41,
It has a non-woven structure made of heat-sealable synthetic fibers such as acrylic fibers, polyurethane fibers, polyvinyl chloride fibers, and vinylon fibers, but when heat-sealed, the substrate (1) passes through the gaps between the fibers. It is better to have a rough structure so that it looks like a porcelain. From this point of view, it is made of fibers with a fineness of about 0.5 to 70 denier and a basis weight of 5 to 120 p/m W.
m degree is preferably used. The shape of the 1ffi surface of the fiber is not particularly limited, and any of circular, elliptical, rectangular, and other irregular shapes may be used.

As described above, in the present invention, the cross-sectional shape of the fibers does not matter because the fibers become flat when the fiber aggregate (2) is thermally fused. A specific example of the darning fiber aggregate (2) is, for example, Dynac LNS 0010.0011.
0012.0013.0 14.0015.0016.
0017.0018.0o19.0020 (All of the above examples include Kureha fiber (made from ceramic polyamide fiber).

In the present invention, a transfer foil is used to apply the metal vapor deposited layer (4) to the fiber (3) heat-sealed onto the base material (1).

This transfer foil has a metal vapor deposited layer (4) only on the fiber (3).
It does not have an adhesive layer to impart
The metal vapor deposited layer (4) is applied only to the portion of the fiber (3) by utilizing the thermal fusibility of the fiber (3). Examples of such transfer foils include those in which a metal vapor deposited layer is provided on a base film such as a polyester film via an aW type layer if necessary. An uncolored or colored resin coating layer which serves as a detail preservation layer for the metal vapor deposited layer after transfer may be interposed between the release layer and the metal vapor deposited layer. Metals for the metal vapor deposition layer include aluminum, silver, platinum, gold,
Any metal that can be deposited by vapor, such as nickel, copper, or titanium, can be used. These are made into a metal vapor deposited layer by a normal thin film forming method such as a vacuum deposition method, a sputtering method, or an ion blating method. The thickness of the metal vapor deposited layer is usually 60 to 150.
It is about mμ.

The patterned gold and silver thread of the present invention is produced by stacking the fiber aggregate (2) and the transfer foil on the flexible substrate (1) in this order, heating and pressurizing the fiber aggregate on the flexible base material (1). The body (2) is heat-sealed and the metal vapor deposited layer (4) is attached onto the fiber (8) by transfer using a transfer foil to form a band-like material.
It can be obtained by slitting it into a width of about mm. The above-mentioned method for producing a strip is advantageous because it allows the transfer foil to be transferred as well as the thermal fusion of the fiber aggregate (2).

In addition, the fiber aggregate (2) is first layered on the flexible base material (1), heated and pressed to coat it with heat n11, and then the transfer foil is layered on top of the fiber aggregate (2) and transferred again by heat and pressure to obtain a strip. Good too.

), θ→, and heat and pressurize there to thermally fuse the fiber aggregate (2) to the flexible base material (1) and perform the transfer, thereby forming the transfer foil (7') of the transfer foil. is wound onto a take-up roll (15), and the obtained strip (8) is wound onto a take-up roll (06). By slitting this strip (8), the gold and silver threads can be changed.

The patterned gold and silver thread of the present invention may be used as a flat foil thread as it is, or it may be used as a twisted gold and silver thread by round twisting it with other fiber threads, or by performing Hagoromo twisting, Tasuki twisting, etc. .

The patterned gold and silver thread of the present invention can be used for the same purposes as conventional gold and silver thread, but for example, it is used by weaving the patterned gold and silver thread into textiles. Specifically, when the base material is Japanese paper, it is used as double-sided thread for obi, Hikihaku base paper is used as Hikihaku for obi, and when the base material is film, it is used as twisted yarn for obi and Western clothing.

Next, the present invention will be explained with reference to Examples.
