Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to gold and silver threads for resist dyeing. More particularly, the present invention relates to gold and silver threads having excellent stain resistance against dyeing with disperse dyes and the like.

Conventionally, gold and silver threads with a one-ply configuration, which are formed by slitting a metal-deposited film in which a metal-deposited layer is provided on a base film such as L-Reester, and a top coat layer is provided on the metal-deposited layer, have been used. Two-ply gold and silver threads are known, which are made by laminating two sheets with the metal vapor-deposited layer on the inside and slitting them.

However, when such conventional gold and silver threads are woven and knitted with, for example, undyed polyester fibers and then dyed with disperse dyes, the gold and silver threads themselves are dyed because the surface of the gold and silver threads is a polyester film. When dyed, the silver thread becomes blue and the gold thread becomes green, and there is a problem in that the metallic luster of the gold and silver thread itself cannot be maintained. Furthermore, conventional gold and silver threads have the disadvantage that their surfaces are easily stained during other processing steps such as weight loss treatment during weaving and knitting.

However, as a result of extensive research in order to solve the above-mentioned problems with conventional gold and silver thread, the present inventor has found that it has excellent stain resistance against dyeing, and is also resistant to staining even with other types of fabrics. I succeeded in firing 11 gold and silver threads.

That is, in the present invention, the metal vapor deposited layer is provided on one side, two Tahes films are laminated with the metal vapor deposited layer on the outside through an adhesive layer, or the metal vapor deposited layer is provided on both sides of the base film. and a gold and silver thread for resist dyeing, characterized in that it is a slit thread of a laminate in which a fluororesin film or a polypropylene film is laminated on the metal vapor deposited layer via an adhesive layer.

The gold and silver thread of the present invention has a structure in which both sides of the conventional gold and silver thread are coated with a fluororesin film or a melipid pyrene film, and because both sides of the gold and silver thread are coated with such a special film, disperse dyes can be used. It has excellent stain resistance against staining by Therefore, when the gold and silver thread of the present invention is woven with, for example, undyed polyester SM and then dyed with a disperse dye, polyester I
Although the IjAIm part is dyed, the gold and silver thread part is not contaminated at all, and the effect is that the woven or knitted fabric retains its original excellent metallic luster. Therefore, it is extremely convenient because conventionally yarn-dyed fibers and metallic materials had to be woven and knitted, but can be piece-dyed on the woven and knitted fabric. Further, during each processing step at the time of weaving, for example, during weight reduction treatment using caustic soda, etc., there is an advantage that the surface is free from dirt and is smooth, making weaving and knitting easy.

Next, the present invention will be described in detail with reference to the drawings.

) is laminated with a fluororesin film or a polypropylene film (4).

The present invention aims to improve the stain resistance of gold and silver threads against dyeing using a polyester film as the conventional base film. Therefore, as the base film (1), a preester film such as polyethylene terephthalate is usually used. Other easily dyed films such as cellulose acetate, pre-cyclized vinyl,
Films such as polyvinylidene chloride are used as base films (
The present invention is also applicable to the case of use as 1). Although the base film (1) may be a non-stretched film, it is usually preferably used as an axially or double-stretched film, and its thickness is usually 2 to 25 P1, preferably 6 to 25 P1.
It is about 12μ.

Examples of the metal vapor deposited layer (2) include single metals such as silver, gold, niranal, lithium, platinum, palladium, indium, and aluminum, and non-deposited layers of alloys or mixtures of two or more of these metals. The formation method is not limited in any way, and any conventional method such as a vacuum evaporation method, a sputtering method, or an ion blating method can be employed.

As the deposited metal, silver is preferably used because of its nobility and excellent color. The thickness of the metal vapor deposited layer (2) is usually about 60 to 100 mm.

Undercoat layer (6) Provided if the adhesion between the Habase film (1) and the metal vapor deposited layer (2) is poor. Examples of the resin paint for the undercoat layer (6) include melamine resin, acrylic resin, and epoxy resin threads, and the thickness thereof is 710.6 to 16 mm.
It is about 5μ.

The top coat layer ()) is provided when a particularly durable gold and silver thread is desired, or when a metallic luster of various colors is desired, not limited to the metallic luster inherent to vapor-deposited metals. 0.0.0 using resin paints such as melamine resin, Kei-kishi resin, urethane resin, etc.
It is formed to a thickness of about 5 to 1.5P. For the latter purpose, the layer may be colored with a coloring agent such as a dye or a transparent pigment.

The adhesive layer (3) used when laminating two metallized films is not particularly limited as long as it has good water resistance and chemical resistance, such as epoxy-isocyanate-F system, pre-ester - Isocyanate-based adhesive steel is used, and its thickness is usually 1 to 2 degrees.

In the present invention, a fluororesin film or polypropylene film (4) is laminated on the outside of the base film (1) via a metal vapor deposition layer (g) and an adhesive layer (5). Examples of the fluororesin fill material include tetrafluoroethylene resin, tetrafluoride ethylene-ethylene copolymer resin, fluoride vinyl loop pyrene copolymer resin, trifluoride ethylene resin, vinylidene hexafluoride resin, Examples include films made of vinyl fluoride resin. The fluororesin film or polypropylene film may be an unstretched film, or a -axially or biaxially stretched film. When an unstretched film is used, there is an advantage that gold and silver threads with excellent texture and feel can be used. The thickness of the fluororesin film or polypropylene film is usually 6 to 2 EspQ degrees.

As the 7-bulk resin film or polypropylene film used in the present invention, one whose one side has been surface-treated to improve adhesion to the adhesive layer (6) is preferably used. Such surface treatment 3i]1m includes corona discharge treatment as common to both films, and treatment methods specific to fluororesin films include) treatment with a tetrahydrofuran solution of a liumona 7-talene complex compound, and a liquid ammonia solution of metallic sodium. Examples include methods of treating the surface of the film. The use of such a surface-treated film is advantageous because it has good adhesion to the adhesive layer (6) and can be used instead of gold and silver threads with excellent durability.

7 bulk resin film or polypropylene film (4
) for laminating the adhesive layer (6) is not particularly limited, and may be formed in the same manner as the adhesive jil (8), for example.

In the case of the gold and silver thread of the present invention shown in FIGS. ) on the outside through an adhesive layer (3), and then a fluororesin film or polypropylene film (4) is laminated on the metal vapor deposited layer (2) through a wI layer agent layer (5), or
Or (S) Before laminating the metallized film, a fluororesin film or polypropylene film (4) is laminated on the side of the metallized layer (2) via an adhesive layer (5), and then two sheets of this film are laminated. It can be obtained by laminating the base film (1) inside through an adhesive layer (8), and in the case shown in No. 654,
The laminate that can be obtained by laminating a metal vapor deposited layer (adhesive layer (6) and a fluororesin film or polypropylene film (4) in this order on both sides of the base film (1)) mic-
It can be obtained by slitting it into a width of 0.15 to 1 m1i degrees using a slitter or the like.

This slit yarn may be used as it is, but it may also be used as a twisted yarn by round twisting the core yarn, hagoromo twisting, or cross-twisting other yarns using the slit yarn as the core.

The gold and silver threads of the present invention include, for example, polyester fibers, polyester ether fibers, polyamide fibers, acrylic fibers,
Suitable for weaving and knitting together with fibers that can be dyed with disperse dyes, such as cellulose acetate fibers, recycled 11-su fibers, and cotton, to make woven and knitted fabrics, and even when such woven and knitted fabrics are dyed with disperse dyes, they are easily dyed. Since the base film (1) is arranged inside the metal vapor deposition layer (2) and is shielded by the metal vapor deposition layer (2), even if the base film (1)
Even if it is dyed, it is not visible to the outside, and the original metallic luster is retained.
