JPH0892834A - Twisted tinsel - Google Patents

Abstract

PURPOSE: To obtain a twisted tinsel without difference between the obverse and reverse side of flat foil yarn, having moderate mechanical strength, twistable with no concern about turning upside down of the flat foil yarn and/or its breakage even in a high-speed twister as well as conventional one, causing no corrosion of the metal deposition layer, free from luster unevenness, and excellent in touch feeling. CONSTITUTION: Firstly, a laminate is prepared by laminating one side of a synthetic resin film of 6-9μm thick such as of polyethylene terephthalate or nylon with a metal deposition layer and a corrosin-proofing coating layer in this order. Second, this laminate is further laminated with another synthetic resin film of 6-9μm thick such as of polyethylene terephthalate or nylon through an adhesive layer by layering the corrosion-proofing coating layer inside. Third, the resultant laminate film are slit in narrow width to form into flat foil yarns. Finally, these flat foil yarns are twisted with any filament yarns to obtain the objective twisted tinsel.

Metal such as aluminum or silver is vapor-deposited on one side of a synthetic resin film, and a corrosion-deposited coating layer containing a thermosetting resin as a main component is provided on the metal vapor-deposited film. There was a twisted gold and silver thread in which a foil thread was twisted with an arbitrary thread. The basic structure of the flat foil yarn used for this is as follows: (a) Synthetic resin film / metal vapor deposition layer / corrosion prevention coating when viewed from the outside when wound around the outer periphery of the core yarn like a bellows twist. Layer, (b) colored resin coating layer / synthetic resin film / metal vapor deposition layer / corrosion prevention coating layer, (c) synthetic resin film / colored resin coating layer / metal vapor deposition layer / corrosion prevention coating layer,

る腐食防止効果が期待できなかった。Therefore, these conventional flat foil yarns have a difference in gloss and color between the front and back. Therefore, when these conventional flat foil threads are wound around the outer periphery of an arbitrary core thread to form a twisted gold and silver thread,
The flat-foil yarn was partially turned inside out, resulting in uneven luster and color, and we could not make a product that looked good. In addition, when conventional flat foil yarn is twisted into gold and silver by using a high-speed twisting machine, defects such as the synthetic resin film itself (such as fish eyes) and pinholes due to splash of evaporation material during metal deposition, etc. The flat foil yarn was frequently cut at the defective portion of. The corrosion-preventing coating layer usually has a thickness of 0.5 to 2 μm, but it is inferior in extensibility to a synthetic resin film, so that it is easily cracked by pulling with a twisting machine and sufficient metal vapor deposition is obtained. The anticorrosion effect on the layer could not be expected.

When it is used for the above, it does not have sufficient strength against rubbing, and it often happens that not only the coloring / corrosion preventing coating layer but also the metal vapor deposition layer rubs off.

る。Therefore, in the present invention, various drawbacks of the twisted gold and silver yarn according to the above-mentioned prior art are caused, that is, the conventional flat foil yarn has gloss and color difference between front and back. When the flat foil yarn is wound around the outer periphery of any core yarn to form a twisted gold and silver yarn, the flat foil yarn is partially turned over,
There is a drawback that unevenness in gloss and color makes it impossible to make a good-looking product, and when twisted with any yarn, the unevenness of gloss and color on the front and back of the flat foil yarn is not noticeable. In addition, when the flat foil yarn is twisted with a high-speed twisting machine to be twisted gold and silver yarn, the defect portion of the synthetic resin film itself (fish eye, etc.) or the defect portion such as pinhole due to splash of evaporation material during metal deposition However, the flat foil yarn is often cut to reduce workability, and the corrosion-preventive coating layer is inferior in extensibility to the synthetic resin film. In addition to the drawback that the effect of preventing corrosion on the layer cannot be expected, in addition, in the case of the above-mentioned (d) colored / corrosion-preventive coating layer / metal vapor deposition layer / synthetic resin film, the colored / corrosion-preventing coating layer is a twisted gold / silver yarn. Since it is the outermost layer, it does not have sufficient strength against rubbing when used for textiles, etc., and it is possible to solve the drawback that not only the coloring and corrosion preventing coating layer but also the metal vapor deposition layer is rubbed off. This is an issue.

On the other hand, a film having a thickness of more than 9 μm is not preferable because the synthetic resin film has a strong property and becomes a rigid twisted gold-silver yarn, which is soft and impairs the supple texture.

Therefore, there is a concern that the flat foil yarn may be turned over or the flat foil may be broken not only in the conventional twisting machine but also in the high-speed twisting machine. Without twisting, the twisted yarn can be processed, the vapor-deposited metal layer is not corroded, there is no uneven gloss, and the texture is excellent.
