Description

Detailed Description of the Invention [Technical Field] The present invention relates to a novel film for gold and silver threads, and more specifically, it has excellent durability and is particularly suitable for scouring, bleaching, and
This film relates to a film for gold and silver threads that is durable against post-processing treatments such as dyeing, has a heat ray blocking function, and provides a cooling sensation on clothing.

[Prior Art] Conventionally, metallized films or films for gold and silver threads have been known, which are formed by vapor-depositing aluminum on a thermoplastic resin film and forming a protective resin layer thereon.

[Problems to be Solved by the Invention] However, in the film for gold and silver thread in which aluminum is vapor-deposited on a thermoplastic resin film and a protective resin layer is formed on the thermoplastic resin film in the conventional example described in 2, the aluminum vapor-deposited layer is exposed in the cross section. Because of this, its durability is significantly inferior. For example, wool products are generally dyed using strong acid as an auxiliary agent, so washing with water is insufficient and the acid tends to remain in the wool.For products with residual acid, use the gold and silver thread film mentioned above. If a product with residual acid is stored in contact with a product using the film for gold and silver thread, the thin aluminum layer may be gradually eroded, although the degree of progress may vary depending on temperature and humidity. In the end, the metallic luster completely disappears.

In addition, when performing subsequent layer treatments such as scouring, bleaching, and dyeing on the woven fabric using the film for gold and silver thread in the conventional example, the aluminum vapor-deposited layer is easily attacked by chemicals such as acids, alkalis, and aphrodisiacs. If the post-processing is carried out under normal post-processing conditions, the aluminum vapor deposited layer will disappear or be eroded and the metallic luster will disappear, so there are restrictions on the types of acids, alkalis, bleaches, etc., and there are restrictions on the concentration, temperature, processing time, etc. of the processing solution. conditions or restrictions. For this reason, the gold and silver threads made from the film for gold and silver threads and the fibers that can be woven and knitted in the conventional cases of serious crimes are limited, and are limited to fibers such as nylon, rayon, acrylic, and acetate, and wool, silk, cotton, and polyester cannot be used. There were a lot of things that weren't there.

As described above, the range of use of the film for gold and silver threads in the conventional example is extremely limited.

In view of the above-mentioned conventional problems, the present invention has excellent durability, and is particularly durable for post-processing such as scouring, bleaching, and dyeing applied to a knitted fabric, and furthermore, has excellent durability against heat rays! An object of the present invention is to provide a film for gold and silver threads that also has an ffr function and provides a cooling sensation on clothing.

[Means for Solving the Problems] The film for gold and silver thread of the present invention is a film for gold and silver thread that is cut into narrow widths and used for gold and silver thread, in which a thin film of stainless steel is applied to at least one piece +r+i I- of a polyethylene terephthalate film. It is characterized by the fact that it was formed.

[Function] The polyethylene terephthalate film used in the present invention has excellent weather resistance and abrasion resistance, and can be dyed with polyester by high-pressure dyeing or carrier dyeing using disperse dyeing agent 1, which is normally used for dyeing polyester. It has the property of being dyed like fiber. In addition, it has excellent vapor deposition suitability when depositing a thin film of stainless steel, and the resulting film for gold and silver threads and/or woven or knitted fabrics can be subjected to post-processing treatments such as high-pressure dyeing with disperse dyes, carrier dyeing, scouring, and bleaching. Due to the synergistic effect with the stainless steel thin film, the condition 11, in which the metallic luster disappears, which was observed in the film for gold and silver thread in the conventional example, is eliminated.

The stainless steel thin film used in the present invention has significantly better durability than the film for gold and silver thread in the conventional example, in which aluminum is vapor-deposited. In addition, when a single knitted fabric is subjected to post-processing treatments such as scouring, bleaching, and dyeing, the thin stainless steel film is not attacked by chemicals such as acid, alkali, or bleach, and the stainless steel thin film disappears or is not attacked. It does not lose its metallic luster, so acid,
There are no restrictions on the use of alkaline agents, bleach, etc., and there are no restrictions on the concentration, temperature, processing time, etc. of the processing solution! 1; The setting is also arbitrary, a, and therefore there is no restriction on the fibers to be woven and knitted with the gold and silver threads made of the film for gold and silver threads of the present invention, and in addition to fibers such as nylon, rayon, acrylic, acetate, etc. Another advantage is that fibers such as silk, cotton, and polyester can also be used.

[Example] Next, the film for gold and silver threads of the present invention will be explained based on side I:A.

1 to 5 are schematic partial cross-sectional views showing examples of the film for gold and silver threads of the present invention, and the one shown in FIG. 18. ! I! ! 2(2) shows the basic structure of the film for gold and silver threads of the present invention, which is a laminated metallized film, and those shown in FIGS. 2 to 5 are other embodiments of the film for gold and silver threads of the present invention. ff, In Figure 0 showing the configuration of the example, (1) is a polyethylene terephthalate film (1), and (2) is a stainless steel Ni II (2) provided on the surface of the polyethylene terephthalate film (1). (3) is a protective resin layer (3) provided on the surface of a stainless steel thin film (2), (
A) is an adhesive layer (2) for bonding metallized films to each other or to other films, and is a protective resin film (51).

The polyethylene terephthalate film (1) used in the present invention is not particularly limited, but is usually 6 to 511-
A thickness of approximately 100 ml is used. If the thickness is less than 6 μs, it will be too soft and sickle will occur, the metallized film will be uneven, and product loss will increase, making it impractical. On the other hand, if the thickness exceeds 50 μs, the metal will have poor flexibility and become hard. Since it becomes a chemical film, even if the gold and silver threads are slit, the hardness will not be resolved, and the resulting F threads will become hard, impairing the texture of clothing, so it is not practical.

In addition, polyethylene terephthalate film (1) has
Hairline processing, matte processing, etc. may be applied to either or both of the front and back surfaces.

The stainless steel thin film used for the stainless steel thin film (2) provided on the polyethylene terephthalate film (1) may be, for example, one made by vapor-depositing low carbon stainless steel, particularly low carbon, 17 to 19% chromium. (
Stainless steel containing 7 to 12% nickel is vapor-deposited with a color that matches people's aesthetic sensibilities and an excellent metallic feel.

In addition, gold and silver thread films and gold and silver threads obtained by a synergistic effect with polyethylene terephthalate film have extremely excellent durability and are preferably used because they have an excellent heat ray shielding WR function.

If the chromium content is less than 17%, corrosion resistance is poor, especially for wool dyeing,
It is not practical because it cannot withstand acid treatments such as cotton bleaching, and on the other hand, if the chromium content exceeds 19%, the color becomes dark and ■
First, internal stress increases and cracks are likely to occur, making it impractical. Also, if nickel is less than 7%, chromium is 1%.
If it exceeds 9% nickel, the color tone becomes dark, internal stress increases, and cracks are more likely to occur, making it impractical. On the other hand, if it exceeds 12% nickel, chromium 17
Corrosion resistance is poor as in the case of less than %, especially when dyeing.

It is not practical because it cannot withstand acid treatment such as hfdp white.

In particular, the stainless steel thin film (2) provided on the polyethylene terephthalate film L is made by vapor-depositing the stainless steel, and its thickness is not particularly limited, but it is preferably about 30 to 20 n-. Thickness: 3 On
If the thickness is less than s, the metallic luster is insufficient and it is too thin, resulting in low corrosion resistance and impractical.
Even if it exceeds 00n-, the metallic luster and corrosion resistance are sufficient, but it is not practical because it is inferior in economical efficiency.

In the specification of this application, does evaporation mean vacuum evaporation? J: Ordinary metals (such as sputtering method and ion blating method)
It means forming a thin film by a thin film forming method such as (including alloys and metal compounds, hereinafter the same).

Furthermore, since the stainless steel thin film (2) itself provided on the surface of the polyethylene terephthalate film (1) has weak mechanical strength and is easily damaged by friction, a protective resin layer is placed on the surface of the stainless steel thin film (2). (It may be possible to provide a turbidity, but there are no particular restrictions on its thickness. It is preferably in the range of 0.5 to 5 μs. The thickness is 0.5 μs.
If the thickness is less than 7A, the protective effect is small and it is not practical as a protective resin layer.On the other hand, if the thickness exceeds 5μs, there is no change in the effect, but it is not economical, and furthermore, the flexibility of the entire sheet is impaired, so it is not practical. There is no.

As the resin coating for forming the protective resin layer (3), a coating made of, for example, a thermoplastic resin, a thermosetting resin, an electron beam curable resin, or an ultraviolet curable resin is used, such as an acrylic resin. system, styrene resin system,
Acrylic-styrene copolymer, vinyl chloride resin, vinyl acetate resin.

Vinyl chloride-vinyl acetate copolymer, polyamide resin system,
Polyvinyl-butyral copolymer, polycarbonate resin system, nitrocellulose resin system.

From China or mixtures such as cellulose acetate resin system, urethane resin system, urine resin system, melamine resin system, urea-melamine resin system, epoxy resin system, alkyd resin system, amino alkyd resin system, rosin modified maleic acid resin, etc. Examples include resin paints.

The protective resin layer (2) can be formed by applying the resin paint for forming the protective resin layer (3) using various methods such as roll coating, gravure coating, reverse coating, spray coating, dip coating, etc. Applied by general coating υ, and dried (
In the case of 8 curable resins, electron beam curable resins, ultraviolet curable resins, etc., this can be done by curing), or by laminating a pre-formed synthetic resin film (c). I can do it.

Alternatively, instead of forming the protective resin layer (3), or a polyethylene terephthalate film (11) on which the protective resin layer (3) is formed, a stainless steel thin film (2) is formed on one side.
The two metallized films formed thereon may be bonded together with the thin film (2) side facing inside through the adhesive layer (a).

The adhesive layer (2) is formed of an adhesive that does not impair adhesiveness, flexibility, and texture. Such Jt-1i
The agent is required to have excellent adhesion to the stainless steel thin film (2) and/or the protective resin layer (3). Adhesives that meet these requirements include ethylene-vinyl acetate-based adhesives, KU-based polypropylene-based adhesives,
Single or blended adhesives such as vinyl chloride-vinyl acetate, acrylic, acrylic-vinyl chloride-vinyl acetate, and polyester-isocyanate are used.
Particularly preferred are polyester-isocyanate adhesives. The lamination method is preferably carried out continuously using a roll method, for example, from the viewpoint of economy and productivity.The thickness of the VL nursing layer is not particularly limited, but is usually in the range of 0.5 to 5 μs, more preferably in the range of 1 to 1 μs. It is selected from a range of 3 μs. If the thickness is less than 0.5 .mu.s, a sufficient adhesive effect cannot be obtained, while if the adhesive layer exceeds 5 .mu.s, the adhesive layer becomes too thick and the texture is impaired, and the drying speed becomes slow, resulting in ineffectiveness. Moreover, the original adhesive strength cannot be obtained, and problems such as residual solvents occur. Furthermore, the adhesive forming the adhesive layer may be suitably colored with a colorant in advance.

The +Ni synthetic resin film (2) is not particularly limited and may be appropriately selected from those used in ordinary films for gold and silver threads, or preferably the same as the polyethylene terephthalate film (1).
