Abstract

<P>PROBLEM TO BE SOLVED: To obtain tinsel so designed that even if a fabric made by weaving the tinsel and synthetic fiber such as of polyester together is dyed with a disperse dye at high temperatures and pressures, only the synthetic fiber is dyed while the tinsel itself is not, thus both hue and metallic gloss inherent in the tinsel can be sustained. <P>SOLUTION: The tinsel is obtained by microslitting a vapor deposition film that is made by laminating plastic film as the substrate with at least metallized layer with a metal or metal oxide deposited and protective layer comprising a silicone resin having polysilane skeleton and/or polysiloxane skeleton; wherein, the protective layer is situated on the outermost layer of one side or both sides of the vapor deposition film. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a gold-silver thread. Specifically, for example, even if a whole woven fabric formed by weaving synthetic fibers and gold-silver threads together is dyed, only the synthetic fibers are dyed at that time. Relates to a hard-to-dye gold and silver thread characterized by not being dyed together.

  Conventionally, gold and silver threads have been used in various fabrics such as clothes and clothing in order to enrich the design and aesthetics. As gold and silver threads used in this way, synthetic resin films are used. A flat foil gold-silver thread with a thin slit made of a metal vapor-deposited film with a metal film such as aluminum or silver deposited on the surface and a thermosetting resin as a main component on the surface, or this flat A twisted gold-silver thread obtained by twisting a foil gold-silver thread and an arbitrary thread is widely used. Fabrics rich in aesthetics are made by weaving these gold and silver threads and synthetic fibers such as polyester fibers together.

  However, when the entire fabric is dyed with a disperse dye to further add design and aesthetics to a fabric woven with gold and silver yarn and synthetic fibers as described above, the surface of the gold and silver yarn is a polyester film. Therefore, not only the synthetic fiber is dyed, but also the gold and silver thread is dyed, and as a result, the original purpose of obtaining the beauty effect by the gold and silver thread cannot be achieved, which is a problem. For example, when dyed with a blue disperse dye, the silver thread portion becomes blue and the gold thread portion becomes green, and the hue and luster derived from the original gold and silver thread are lost, which is a problem.

  Therefore, in order to solve such a problem, for example, Patent Document 1 proposes a gold-silver thread provided with a urethane fluoride resin coating layer as an outermost layer. This consists of preparing two base films with metal vapor deposition layers, and then bonding the two base films together with an adhesive layer with the metal film vapor deposition layers on the base films facing each other. In addition, it is configured such that a fluorinated urethane resin coating is formed on the base film. By adopting such a configuration, when a woven gold / silver yarn and synthetic fiber as described above are dyed with a disperse dye, the fluorinated urethane resin film is protected even if the gold / silver yarn is exposed to the disperse dye. Since it acts as a layer, the gold-silver thread is not dyed with disperse dyes, and therefore, the metallic luster of the gold-silver thread can be maintained.

JP 58-13734 A

  However, in the case of the invention described in Patent Document 1, since the fluorinated urethane resin itself is very expensive, if it is carried out as described, the cost required for its production is very high. Therefore, it is impossible to make the price suitable for the gold and silver thread to be actually used. As a result, it is not practical and is a problem. In addition, since the film thickness of the fluororesin resin coating itself is thin, the contamination by the disperse dye cannot be completely stopped in practice, and as a result, it is not practical and problematic.

  Therefore, it is conceivable to use a fluororesin film as the base film, but even in this case, the fluororesin film itself is still expensive, has poor processability, and has poor adhesion to the deposited layer. Therefore, it is not realistic to use this actively. Although it is conceivable to use a polypropylene film as the base film, the workability of the polypropylene film itself is still poor, and the adhesion with the vapor deposition layer is also weak. And since it does not have heat resistance, it is impossible to dye a woven fabric using gold and silver yarns with this film as a base material at high temperature and high pressure. From the viewpoint of processability alone, it is possible to use a polyethylene naphthalate film, but the problem of difficulty of dyeing, which is difficult to dye even if gold-silver yarn is produced by a conventional method using this film, is not solved. It was.

  The present invention has been made in view of such problems, and its purpose is to be dyed with various post dyes such as direct dyes, acid dyes, cationic dyes, vat dyes, reactive dyes, disperse dyes, etc. However, even if a woven fabric in which a synthetic fiber such as polyester and a gold-silver thread are woven together is dyed with a disperse dye at high temperature and high pressure, the synthetic fiber It is possible to keep the original hue and metallic luster unique to the original gold-silver thread, i.e., the gold-silver thread having difficulty in dyeing, which can be dyed after dyeing. Is to provide.

  In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention includes a metal vapor deposition layer obtained by vapor-depositing at least one of or both of a metal and a metal oxide on a plastic film as a base material, and polysilane. A gold-silver thread obtained by microslit a deposited film formed by laminating a protective layer containing a silicon resin having either or both of a skeleton and a polysiloxane skeleton, wherein the protective layer is the deposited film It is located in the outermost layer of the one side or both sides of this.

  The invention according to claim 2 of the present invention is a vapor deposition film obtained by laminating a metal vapor deposition layer formed by vapor-depositing at least one of a metal and a metal oxide on one side of a plastic film as a base material, It is obtained by sticking two vapor-deposited films and micro-slit a laminate formed by laminating a protective layer containing a silicon resin having either or both of a polysilane skeleton and a polysiloxane skeleton on the surface. It is characterized by.

  The invention according to claim 3 of the present invention is the gold-silver yarn according to claim 1 or claim 2, wherein the silicon resin is either or both of a silane-based condensate and a siloxane-based condensate. Features.

Any one or more metals in the metal group consisting of nickel, indium, palladium, or any one or more oxides obtained by oxidizing the metal group, or the metal group One or a plurality of metals and one or a plurality of oxides obtained by oxidizing the metal group are vapor-deposited.

  As described above, in the case of the gold-silver thread according to the present invention, the outermost layer is provided with a protective layer containing a silicon resin having a polysilane skeleton or a polysiloxane skeleton, and this protective layer is a barrier against dyeing with a dye. Therefore, it is possible to obtain a gold-silver yarn that is not dyed even by various post-dyeing actions, that is, a gold-silver yarn that is difficult to dye. And even if post-dyeing the woven fabric using the gold-silver yarn according to the present invention, the gold-silver yarn is not dyed, so that the glitter, softness, hue and gloss of the gold-silver yarn are not impaired at all.

Embodiments of the present invention will be described below. The embodiment shown here is merely an example, and is not necessarily limited to this embodiment.
(Embodiment 1)
The gold and silver thread according to the present invention will be described as a first embodiment.

Conceivable. Furthermore, it is also conceivable to freely select and use a plurality of the above-mentioned metals and metal oxides. If necessary, it is only necessary that the obtained gold and silver thread looks gold or silver due to its metallic luster.

  Next, the protective layer will be described. This protective layer is made of a silicon resin having either or both of a polysilane skeleton and a polysiloxane skeleton. When such a resin is used, the layer obtained is As a result, it becomes a dense and hard-cured cured film. As a result, even if it is dyed with various post-dyeing dyes, etc., it is not dyed by such dyes, and also acts as a barrier film. If such a protective layer is provided on the surface on the contact side, it can also be used as a protective layer for the metal vapor deposition layer. Further, as will be described later, if a specific silicon resin is used, it is possible to obtain an environment-friendly gold and silver thread.

  The silicon resin forming the protective layer is not particularly limited as long as it is a substance that can achieve the above-mentioned effects and achieve the purpose. For example, either a silane condensate or a siloxane condensate or It may be both, or may be one or more of alkoxysilane, silazane, organopolysiloxane, silicone alkyd, silicone polyester, silicone epoxy, melamine modified silicone, phenol silicone, It can also be considered. Above all, by selectively using silicon resins such as alkoxysilanes, silazanes, organopolysiloxanes, silicone alkyds, silicone polyesters, and silicone epoxies, non-formalin compatible gold and silver threads can be provided, that is, from the viewpoint of environmental problems It can be preferable.

  Further, although not described in detail here, known substances such as slip agents, leveling agents, colloidal silica, acrylic-modified silica particles, ultraviolet absorbers, antibacterial agents, dyes, pigments, etc., are used depending on the purpose and necessity of the protective layer. , May be appropriately selected and added.

  The vapor deposition film for forming the gold and silver thread according to the present embodiment is configured to use at least the above-described substances. In addition to this, for example, an anchor coat layer or a top coat layer with a known substance by a known technique It may be possible to provide the above in advance, or the implementation may be carried out. However, further explanation thereof will be omitted here.

Next, a method for producing the gold and silver thread according to the present embodiment using each member described above will be described. First, a polyester film having a thickness of 12 μm is prepared as a plastic film serving as a base material, and aluminum is deposited on both sides thereof. Let About the method used when making it vapor-deposit, you may be a conventionally well-known method like a vacuum evaporation method, sputtering method, etc., for example.

  Next, a paint containing silicon resin is applied as a protective layer to the respective surfaces of the aluminum layers laminated on both sides of the plastic film. As described above, the silicon resin in this case may be a silicon resin containing either or both of a polysilane skeleton and a polysiloxane skeleton, and may be a specific one as described above.

  Further, the coating material containing the silicon resin is not particularly limited, and the specific compounding substance and the ratio thereof are not particularly limited. Here, 60 parts of silicone alkyd, 30 parts of alkoxysilane, colloidal silica are used. A paint having a blending ratio of 1 part and 1 part of pigment is used. The method of applying the paint may be a conventionally known method such as gravure coating or reverse coating. The thickness of the applied coating layer, that is, the protective layer is preferably 0.5 μm or more and 5.0 μm or less. When the thickness is less than 0.5 μm, the effect as the protective layer is not exhibited, and when the thickness exceeds 5.0 μm, the thickness of the entire gold-silver thread is increased and the flexibility is lost. Here, the thickness was set to 2.0 μm.

  And the gold-silver thread which concerns on this Embodiment is obtained by carrying out the micro slit of the vapor deposition film obtained in this way by a conventionally well-known method. In addition, although the case where the metal vapor deposition layer and the protective layer were laminated | stacked on both surfaces of the plastic film used as a base material here was demonstrated, for example, a metal vapor deposition layer and a protective layer are laminated | stacked only on the single side | surface of a plastic film, and a metal vapor deposition layer The protective film may be laminated on the surface of the plastic film on the side on which no film is laminated. However, even in this case, a gold and silver thread can be obtained in the same manner as described above, and thus further detailed description is omitted here.

  In this way, a coating containing a silicon resin having a polysilane skeleton or a polysiloxane skeleton is applied to the outermost layer, and a protective layer that is not easily contaminated is formed on the outermost surface, thereby making the gold-silver yarn having incompatibility Is obtained. In addition, a gold agent obtained by appropriately selecting and adding slip agents, leveling agents, colloidal silica, acrylic-modified silica particles, ultraviolet absorbers, antibacterial agents, dyes, pigments, and the like in the paint. This makes it possible to improve processing suitability in silver yarn, to make coloring a preference, and to provide functionality. Furthermore, since the gold-silver yarn according to the present embodiment uses only one plastic film as a base material, the thickness of the entire gold-silver yarn obtained can be reduced, and thus the gold-silver yarn that is lightweight and excellent in texture. It becomes possible.

It should be noted that any other conventionally known material may be used as the anchor coat layer, and as described above, the anchor coat layer may be omitted.

  Next, silver is deposited on the surface of the anchor coat layer. This vapor deposition is performed in the same manner as in the case of vapor deposition of aluminum described in the first embodiment. And a topcoat layer is provided by apply | coating a thermosetting acrylic resin to the surface of a silver vapor deposition layer. The technique used in this case may be a conventionally known technique such as a gravure coating method or a reverse coating method. It should be noted that a top coat layer made of a conventionally known material other than this may be used, and it is also conceivable to omit the top coat layer as described above.

  Next, two vapor-deposited films obtained are prepared and bonded together so that the respective topcoat layers face each other to form one laminate. When attaching two vapor deposition films, you may use well-known adhesives, such as a polyester adhesive agent, for example.

  Subsequently, the coating material containing a silicon resin is apply | coated with respect to the outermost surface in the both sides of the obtained laminated body. The paint used at this time is the same as that described in the first embodiment, and the thickness thereof is also the same.

  And the gold-silver thread which concerns on this Embodiment is obtained by carrying out the micro slit of the obtained vapor deposition film by a conventionally well-known method.

  With the gold and silver thread thus obtained, it is possible to obtain a gold and silver thread excellent in fastness by using two plastic films.

  In addition, although prepared two sheets of vapor deposition film provided with the composition of polyester film / anchor coat layer / silver vapor deposition layer / top coat layer here, the top coat layers were stuck so as to face each other to obtain a laminate, For example, it is possible to obtain a laminated body by sticking so that polyester films face each other, or to obtain a laminated body by sticking such that a polyester film and a top coat layer face each other. However, in any case, only the surface to be attached is different, and other than that is the same as the above description, so the description in these cases is omitted here.
