Description

[Detailed description of the invention] 3 Detailed explanation of the invention [Industrial application field] The present invention relates to gold and silver thread for georgette.

[Conventional technology]

Conventionally, gold and silver threads for georgette are made of a film-like material made by sequentially forming an anchor coat layer, a metal vapor deposition layer, and, if necessary, a top coat layer on one side of a polyester film.
It is known that a laminated film is formed by slitting a laminated film that is laminated with the metal vapor deposited layer (or top coat layer) on the inside.

[Problem that the invention seeks to solve]

However, the conventional gold and silver thread for georgette has the following drawbacks.

(1) Since the outermost layer is a polyester film, it has poor flexibility as a gold and silver thread.

(2) The reduction rate in the weight reduction process for making georgette is limited to a maximum of about 18%, and the resulting georgette has poor texture.

(3) Polyester film is difficult to dye;
Only high-pressure staining can be applied. Naturally, normal pressure staining is impossible.

(4) When trying to use the slit yarn as a twisted yarn by round twisting it with other yarns 1. Since the slit yarn has poor flexibility as described above, it is difficult to twist the yarn.

(5) Even if you try to cut the thread into small pieces, the conventional method is 120 cuts (0,2
The limit is 52 mm width) to 130 cuts (0.233 mm width).

The object of the present invention is to eliminate the above-mentioned drawbacks of conventional gold and silver threads for georgettes and to provide gold and silver threads that can be used satisfactorily for georgettes.

[Means for solving problems]

In the present invention, a metal vapor deposited layer is provided on at least one side of a polyester film via an anchor coat layer, and a polyamide film is laminated on both sides of a film-like product with an adhesive layer provided thereon. The present invention relates to a gold and silver thread for georgette, characterized in that it is a slit thread of a laminated film having the following structure.

〔Example〕

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

FIG. 1 is a schematic partial sectional view showing one embodiment of the gold and silver thread for georgette according to the present invention.

In FIG. 1, (1) is a polyester film, on one side of which is provided a metal vapor deposited layer (3) via an anchor coat layer (2), and furthermore a top coat layer (4). A polyamide film 021 is laminated on both sides of the film-like material O0 via an adhesive layer 01).

As the polyester film (1) used in the present invention, a polyethylene terephthalate film is preferably used, and its thickness is about 5 to 35 mm. The polyester film (1) may be an unstretched film, but usually -
Axial or biaxially stretched films are preferably used.

Anchor coat layer (2) is polyester film (1)
There is no particular restriction as long as it improves the adhesion between the metal vapor deposited layer (3) and the metal vapor deposited layer (3) and has a sufficient protective effect on the metal vapor deposited layer (3). For example, melamine resin type, curable acrylic resin type,
Dry coating amount of resin paint such as epoxy resin 0.5-1
．． It is formed by coating at about 5 g/rrr.

The anchor coat layer (2) may be colored with dye, transparent pigment, etc. as appropriate.

Examples of the metal vapor deposition layer (3) include vapor deposition layers of single metals such as silver, gold, nickel, chromium, platinum, palladium, indium, and aluminum, and alloys or mixtures thereof. Any conventional method such as , sputtering method, or ion blating method may be employed. Its nobility as a vapor deposited metal,
Silver is particularly preferably used because of its excellent color and corrosion resistance. The thickness of the metal vapor deposited layer (3) is usually about 50 to 150 mμ.

The top coat layer (4) is not particularly limited as long as it has a sufficient protective effect for the metal vapor deposited layer (3). For example, it is formed by applying a resin paint such as urea resin, melamine resin, epoxy resin, or urethane resin in a dry coating amount of 0.5 to 1.5 g/1rd.

Usually the anchor coat layer (2), metal vapor deposition layer (3)
And the top coat layer (4) is a polyester film (
Although it is sufficient to form it on only one side of 1), it may be formed on both sides.

A polyamide film 02) is bonded to both sides of the film-like material 00) via the adhesive layer.

As the polyamide film side, films such as nylon-6, nylon-66, and nylon-12 can be used, and the thickness thereof is about 10 to 40. The polyamide film side may be a non-stretched film, but
Ordinary-axis or two-wheel stretched films are preferably used.

The equilibrium water absorption rate of polyamide film 02) is 0.5.
% or less (value at 70% R1+, same below),
It is preferable that the dimensional change rate due to water absorption is 0.25% or less (value after immersion in water at 20° C. for 150 hours, the same applies hereinafter). In addition, when the gold and silver thread of the present invention is mixed with polyester fiber and then dyed, it can withstand high pressure dyeing conditions.
Those having a melting point of 150°C or higher, preferably <170 to 178°C, are preferable. From this point of view, a nylon-12 film that can particularly satisfy these conditions is preferably used.

The polyamide film Oz preferably has its adhesive surface subjected to surface treatment such as corona discharge treatment in order to improve adhesiveness.

The adhesive used for the adhesive layer is not particularly limited as long as it has excellent water resistance and chemical resistance. For example, epoxy-isocyanate adhesives, polyester-isocyanate adhesives, etc. are used, and after drying The coating amount is about 1 to 3 g/g.

The thus obtained laminated film is slit into a width of about 15 to 1 mm to obtain slit threads.

In the present invention, since the outermost layer is a flexible polyamide film, 120-cut (0,252n+m width) to 1
Finely chopped threads of about 50 pieces (0.202 mm width) can be easily obtained.

The above-mentioned slit yarn may be used as a flat yarn as it is, but by taking advantage of its flexible properties, it can be twisted round into a core yarn, twisted into hagoromo (hagoromo), or twisted with other yarns using the slit yarn as a core. It may also be used as twisted yarn.

To make georgette using the gold and silver thread of the present invention, it is mixed with polyester fiber and subjected to weight reduction treatment. Since the gold and silver threads of the present invention can be subjected to weight loss treatment within a weight loss rate range of 5 to 35%, there is a wide range of weight loss processing, and the texture of the resulting georgette can be improved compared to the past.

The obtained georgette is subjected to a dyeing process.

In that case, both the gold and silver thread and the polyester fiber can be dyed by high-pressure dyeing, but the gold and silver thread is dyed more vividly than the conventional gold and silver thread for georgette, whose outermost layer is a polyester film. Additionally, only the gold and silver threads can be dyed by atmospheric pressure dyeing, but this is not possible with conventional gold and silver threads for georgettes.

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

Example 1 33 parts by weight of Hytaloid 2577D (Hitachi Chemical's packaging hardening acrylic resin) and 33.5 parts by weight of xylene were placed on one side of a 12-thick polyethylene terephthalate film.
A resin solution consisting of 33.5 parts by weight and 33.5 parts by weight of butanol was coated with a gravure coater at a dry coating amount of 0.8 g/rrr, dried to form an undercoat layer, and pure silver was vacuum-deposited thereon to a thickness of 500 people. A silver vapor deposition layer is formed, and on top of that, Melan 474-A (Hitachi Chemical ■

Apply a resin solution with a dry coating amount of 0.95 g/go,
It was dried to form a top coat layer.

On both sides of the film, 45 parts by weight of Takelac A-31O (polyester polyol resin manufactured by Takeda Pharmaceutical Company Ltd.), 5 parts by weight of Takenate A-3 (polyisocyanate resin manufactured by Takeda Pharmaceutical Company Ltd.), and 25 parts by weight of ethyl acetate. A dry coating amount of an adhesive solution consisting of 25 parts by weight and 25 parts by weight of methyl ethyl ketone was applied in an amount of 5 g/1rd, and a nylon-12 film (Daicel $ manufactured by Daicel Chemical Industries Ltd. The corona discharge treated surface of 7000) was laminated and left in a thermostat at 40° C. for 24 hours to cure.

Melting point: 172-178℃ Yield point strength: 450kg/cI# Equilibrium water absorption: 0.5% Water absorption dimensional change rate: 0.2% Moisture permeability: 75g / rrr / 24hr (25℃
) The obtained laminated film was microslit into 120 pieces (width 0.253 mm) to obtain silver threads.

This silver thread is mixed with polyester fiber thread (high count thread) to create a gray fabric, and this gray fabric is mixed with 40% sodium hydroxide.
The weight loss treatment was carried out under the conditions of g/I, 100° C., and 60 minutes, and a weight loss rate of 25% was obtained.

Next, acetic acid 1g/II, Monogen #170 (surfactant manufactured by Daiichi Kogyo Seiyaku ■) 0.5g/j? , Sumikaron Blue (disperse dye manufactured by Sumikagaku Kogyo ■) 3% ovf, 1
High-pressure dyeing was carried out at 3.0° C. for 60 minutes, followed by soaping to obtain raw georgette cloth.

The resulting georgette fabric was dyed a beautiful blue color in both the silver and polyester threads. The dyeing of this silver thread portion was more vivid than that of conventional gold and silver threads whose outermost layer was a polyester film. This georgette fabric also had an excellent texture that had never been seen before.

Example 2 The laminated film obtained in Example 1 was cut into 130 pieces (0,23
A twisted silver thread was obtained by twisting the micro-slit silver thread into a nylon core thread (150 denier) using a twisting machine.

This twisted silver yarn was mixed with polyester yarn in the same manner as in Example 1 to create a gray fabric, which was then hydrated with 40 g of thorium/
The weight loss treatment was carried out under the conditions of Ω, 100°C, and 60 minutes, and a weight loss rate of 30% was obtained.

Next, normally we would have dyed it using high pressure dyeing, but in order to dye just the silver thread to our liking, we used normal pressure dyeing.

Namely, acetic acid 1g/Ω, Aladdin D (surfactant manufactured by Daiichi Kogyo Seiyaku ■) 0.5g/ρ, Techilon Red 2B
(Acid dye manufactured by Ciba Geigy) 3% owf, 1.
Dyeing was carried out under atmospheric pressure at 00°C for 60 minutes, followed by soaping.

As a result, we were able to create a Georgette fabric in which only the silver threads were dyed a beautiful red, which was previously impossible. This georgette fabric also had excellent luster and texture.

〔Effect of the invention〕

By using a polyamide film as the outermost layer of the gold and silver thread for georgette, the following effects are achieved.

(1) Excellent flexibility as gold and silver thread.

(2) The weight loss rate in weight loss processing can be increased to a maximum of about 35%, and the texture of the resulting georgette is improved.

(3) It is easy to stain, and not only high pressure staining but also normal pressure staining is possible.

(4) Because it is flexible, it can be used as twisted yarn.

(5) It is possible to cut into smaller pieces than conventional ones.

(6) The gloss of the surface increases to give it a soft luster.
