Description

  The present invention relates to a stretchable metallic glossy yarn capable of maintaining a good and stable metallic luster even when stretched and a twisted yarn using the same.

  As a metallic luster yarn, a base film layer made of a plastic film such as a polyester film, a metal thin film layer formed on the surface of the base film layer by vacuum deposition using aluminum, pure silver or other metal, and the metal thin film layer Conventionally, flat foil yarns having a laminated structure consisting of a thin film protective layer formed on the surface and twisted yarns using the same are known, and these materials have a brilliant metallic luster on materials such as woven fabrics, knitted fabrics, embroidery items, and sewn items. Widely used for granting.

  However, in the case of the conventional metallic glossy yarn, once it is stretched, a number of irreversible cracks enter the metal thin film, and not only at the time of stretching but also after the cancellation of stretching, that is, in any state of expansion or contraction. However, since the metallic luster and glossiness are remarkably slowed down, it has been difficult to apply such metallic luster yarn to materials such as stretchable clothing, which is a rapidly growing clothing field.

  To solve the above problem, for example, in Japanese Patent Application Laid-Open No. 60-59146, an elastic yarn such as a polyurethane elastic fiber is wound around a glossy flat yarn such as a lame yarn, and then elastic elasticity of the elastic yarn is obtained. There has already been disclosed a decorative yarn to which the glossy flat yarn is contracted so as to be bent in a wave shape by contraction, and an elastic yarn is entangled therewith, thereby giving stretchability (Patent Document 1).

  Japanese Patent Application Laid-Open No. 10-1833 discloses a core yarn made of an elastic yarn such as polyurethane-based elastic fiber and wound with a foil yarn such as a gold-silver yarn or a lame yarn in one direction in a state where the core yarn is stretched to a certain length. And then twist the other yarn around it in the opposite direction, or wind the other yarn around the core yarn that is made by aligning the elastic yarn that has been stretched to a certain length and the foil yarn such as gold-silver yarn or lame yarn. Design yarn that can be stretched by forming a loop of foil thread such as gold-silver thread or lame thread around the elastic thread in a state where the elastic thread used as the core thread is unstretched Has already been disclosed (Patent Document 2).

  However, the conventionally known stretchable decorative yarn or the like has one of foil yarn such as gold-silver yarn and lame yarn and elastic yarn such as polyurethane elastic fiber as the other in order to ensure both metallic luster and stretchability. Because it is twisted by entanglement or winding, etc., even if it can exhibit its own unique texture, it is inevitable that there is a lack of metallic luster and glitter, there is also a sense of stiffness, because of those problems Applications were greatly limited.

  In view of the above problems, an object of the present invention is to provide a stretchable metallic glossy yarn that does not feel stiff and can maintain excellent metallic luster and glitter even when stretched and a twisted yarn using the same.

  The stretchable metallic glossy yarn according to the present invention includes a base film layer, a metal thin film layer formed on the surface of the base film layer, and a thin film protection formed on the surface of the metal thin film layer as described in claim 1. A metallic glossy thread including a laminated structure composed of layers, wherein the metal thin film layer is formed of a discontinuous metal thin film, and the base film layer and the thin film protective layer are transparent including other layer constituent members other than the above. It is characterized by having elasticity.

  The stretchable metallic luster yarn includes a transparent and stretchable base film layer, a metal thin film layer formed of a discontinuous metal thin film formed on the surface of the base film layer, and a transparent and stretchable metal film formed on the surface of the metal thin film layer. It is manufactured by cutting a metal thin film forming film containing a laminated structure composed of a stretchable thin film protective layer into a narrow width.

  As the layer configuration of the stretchable metallic luster yarn, various layer configurations including a laminated structure composed of a base film layer, a metal thin film layer, and a thin film protective layer can be implemented. As a layer configuration including one base film layer, for example, a normal layer configuration including a base film layer, a metal thin film layer formed on the surface of the base film layer, and a thin film protective layer formed on the surface of the metal thin film layer Alternatively, it is possible to adopt a layer configuration in which some aspects are modified within the range of the layer configuration. In order to give a colored metallic luster to the layer structure, a first colored layer is formed on the outer side of the base film layer in the layer structure, for example, as in claim 2, and the metal A layer configuration in which a second colored layer that also serves as a thin film protective layer is formed on the surface of the thin film layer, or a layer configuration in which some aspects are modified within the range of the layer configuration can be adopted. Instead of forming the first colored layer on the base film layer, the base film layer itself can be dyed as required.

  In addition, as the layer configuration of the stretchable metallic luster yarn, a layer configuration in which a metal thin film layer or the like is sandwiched between two base film layers as described in claim 3 can be adopted. As the layer configuration, for example, as described in claim 4, a layer configuration in which a second base film layer also serving as a thin film protective layer is formed on the surface of the metal thin film layer formed on the surface of the first base film layer, or It is possible to adopt a layer configuration in which some aspects are modified within the range of the layer configuration. Further, in order to give a colored metallic luster to the layer structure, for example, as described in claim 5, the first base film layer surface is provided with a first colored layer that also serves as a pretreatment undercoat layer. A layer configuration in which the second base film layer is formed via the second colored layer that also serves as a thin film protective layer on the surface of the metal thin film layer and a part of the aspect within the range of the layer configuration. A deformed layer structure can be employed. Instead of forming the first colored layer and the second colored layer, the first base film layer itself and the second base film layer itself can be dyed as required.

  Furthermore, as another layer configuration in which the metal thin film layer or the like is sandwiched between two base film layers, for example, as described in claim 6, a metal thin film layer is formed on the surface of the base film layer. Within the range of the layer configuration and the layer configuration in which the two sets of laminates are bonded together via the adhesive layer with the metal thin film layers inside, and the adhesive layer also serves as the thin film protective layer in each laminate.

  The metal thin film layer made of the discontinuous metal thin film has been conventionally known to have a non-conductive and radio wave reflecting property and a decorative effect to increase the gloss (Patent Documents 3 and 4). The present invention was completed by paying attention to the fact that this layer can flexibly follow and respond without causing cracks even when the base film layer expands and contracts, and can maintain excellent metallic luster and glitter. It is.

  As the base film layer, for example, a polyurethane-based transparent stretchable plastic film is suitably used as described in claim 10. The thin film protective layer, undercoat layer, colored layer and the like are transparent and stretchable from various resins such as alkyd resin, epoxy resin, polyurethane resin, acrylic resin, and paints such as rack varnish, oil varnish, lacquer, etc. Those having the following are appropriately selected.
