Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brilliant spinning yarn using a metallic luster yarn, and a textile product using the same. More particularly, the present invention has a soft brilliancy and a soft texture. Also used for bright spinning with excellent antibacterial properties, and textile products using it, especially products that directly touch the skin such as underwear, socks, pantyhose, towels, baby clothes, sweaters, lining of clothes, etc. Also, the present invention relates to a textile product which has no tingling sensation, has excellent touch, and has soft glitter and antibacterial properties.

[0002]

2. Description of the Related Art Conventionally, as a metallic luster yarn having a metallic luster, a metallic luster yarn obtained by slitting a laminate in which at least a metal thin film layer is formed on a plastic film, that is, a flat gold-silver yarn or a flat gold-silver yarn is used as another yarn. Twisted gold and silver yarns are known, and flat gold and silver yarns and fiber products using twisted gold and silver yarns are also used for various purposes.

[0003] Also, a spinning yarn is known in which at least a metallic luster yarn having a metal thin film layer formed on a plastic film is used as a core yarn and short fibers are used as a sheath yarn. For example, JP
JP-A-00-54234 discloses a spinning twisted yarn in which a metal glossy yarn obtained by slitting a laminate of at least a substrate and a metal thin film layer is used as a core yarn, and a short fiber group is used as a sheath yarn. There is described a fabric in which a short yarn group as a sheath yarn is removed from the used fabric by opal processing or the like, and a core yarn appears at an arbitrary portion.

[0004]

However, conventional flat gold silver yarn, twisted gold silver yarn, and fiber products using them have the following disadvantages. Conventional flat gold and silver yarns and twisted gold and silver yarns have many exposed portions of gold and silver yarns, so they have a brilliant glitter of metallic luster and do not have a soft (calm) glitter.
Therefore, fiber products using the conventional flat gold silver yarn or twisted gold silver yarn also have brilliant glitter, and soft glitter cannot be obtained. In addition, since conventional flat gold silver yarn and twisted gold silver yarn have a firm texture as a whole, in the case of textile products using them, such as underwear, socks, and towels that directly touch the skin, touch the skin. There was a tingling sensation and the so-called feel was bad.

[0005] Further, the spinning twisted yarn described in JP-A-2000-54234 and the fabric using the same have the following disadvantages. The spinning twisted yarn did not have any glitter since the core yarn, which is a metallic luster yarn, was completely covered with the sheath yarn composed of the short fiber group and the core yarn was not exposed at all.
More specifically, since the sheath yarn composed of the short fiber group is in a dense state, that is, the sheath yarn is in a tight state, no gap is formed in the sheath yarn. Since the core yarn was covered, the core yarn was completely covered with the sheath yarn, and as a result, the core yarn could not be exposed at all and could not have any glitter. Therefore,
The fabric using the spun twisted yarn has, of course, no luster at all. Assuming that the fabric using the spun cross-twisted yarn is to exhibit glitter, the core yarn is removed by removing the short yarn group which is a sheath yarn by opal processing or the like as described in the above publication. It must be revealed at an arbitrary portion, and in this case, only the arbitrary portion from which the short fiber group has been removed shows a brilliant glitter, and the fabric does not have a soft glitter. In addition, even if the metallic luster yarn, which is the core yarn, has antibacterial properties, it is completely covered with the sheath yarn composed of short fibers, and the metallic luster yarns are not exposed at all. It had no antimicrobial properties at all, and the fabric using it, of course, did not have any antibacterial properties.

SUMMARY OF THE INVENTION The present invention is intended to eliminate all of the above-mentioned disadvantages, and to provide a brilliant spun yarn having a soft brilliancy, a soft texture and an excellent antibacterial property, and a textile product using the same. The present invention is intended to provide a fiber product having soft glitter, excellent touch, and excellent antibacterial properties.

[0007]

Means for Solving the Problems (1) The present invention relates to a fine spinning yarn in which at least a metallic luster yarn formed by forming a metal thin film layer on a plastic film is used as a core yarn and a short fiber is used as a sheath yarn. It is a glittering spun yarn characterized in that it is not completely covered with a sheath yarn and a core yarn is randomly exposed. (2) The present invention is the glittering spinning yarn according to (1), wherein the metal thin film layer is an Ag thin film layer or a Cu thin film layer and has antibacterial properties. (3) The present invention is a textile product using the glittering spinning yarn according to (1) or (2).

[0008] The glittering spinning yarn of the present invention is a spinning yarn in which at least a metal luster yarn having a metal thin film layer formed on a plastic film is used as a core yarn and short fibers are used as a sheath yarn.
Since the core yarn is not completely covered with the sheath yarn, and the core yarn is randomly and appropriately exposed, as a result, it has a soft glitter. Therefore, a textile product using the glittering spinning yarn of the present invention also has soft glittering properties not in an arbitrary part of the textile product but in the entire textile product.

Further, since the glittering spinning yarn of the present invention is a spinning yarn using a metallic luster yarn as a core yarn and a short fiber as a sheath yarn, it has a firm texture like conventional flat gold silver yarn or twisted gold silver yarn. And soft, so that the textile products using the glittering spinning yarn do not have a tingling sensation when touching the skin and have a so-called soft touch, so that underwear, socks, pantyhose, towels, baby clothes, sweaters, lining of clothes, etc. It can be used satisfactorily for products that directly touch the skin like.

[0010] If the metallic thin film layer of the glittering spinning yarn of the present invention is formed of an Ag thin film layer or a Cu thin film layer, the glittering spinning yarn and a fiber product using the same have antibacterial properties. It will be excellent.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The metallic luster yarn serving as the core yarn of the glittering spun yarn of the present invention is one in which a metal thin film layer is formed on at least a plastic film. And antimicrobial properties.

The plastic film used for the metallic glossy yarn is not particularly limited as long as it is a plastic film used for the conventional metallic glossy yarn. For example, a polyethylene terephthalate film, a polyethylene film, a polypropylene film, a polyamide film and the like can be used.

The thickness of the plastic film is 3-25.
μm is preferred, and more preferably 6 to 12 μm.

The metal thin film layer formed on the plastic film of the metallic luster yarn has metallic luster, and as a result, imparts glitter to the glitter spinning yarn of the present invention.

The metal used for the metal thin film layer is not particularly limited as long as it satisfies that the metal has a metallic luster when the metal thin film layer is formed using the metal. , Ni, Cr, Zn, Au, Ag, Cu, etc. can be used. In particular, if the metal thin film layer is formed using antibacterial Ag or Cu, the glittering spinning yarn is provided with glittering properties, Excellent antibacterial properties can also be imparted.

As a method for forming the metal thin film layer, conventionally known methods such as a vacuum evaporation method, a sputtering method, an electron beam evaporation method, and an ion plating method can be used.

The metallic luster yarn serving as the core yarn of the glittering spinning yarn of the present invention only needs to have at least a structure in which a metal thin film layer is formed on a plastic film. For example, a metal thin film layer is formed directly on one surface of a plastic film. , A structure in which an anchor layer is formed between a plastic film and a metal thin film layer for the purpose of improving adhesion, heat resistance, corrosion resistance, etc .; And a structure in which both an anchor layer and a top coat layer are formed. Further, an antibacterial agent may be mixed in the anchor layer or the top coat layer for the purpose of improving antibacterial properties, or a dye or pigment may be mixed for the purpose of coloring. Further, a plastic film having a metal thin film layer formed on one side thereof, or a plastic film having a metal thin film layer formed on one side thereof and a plastic film,
A structure in which the metal thin film layer side is inside and the structure is bonded with an adhesive or the like, or a structure in which an anchor layer and a top coat layer are combined with the structure as described above may be used. The metal glossy yarn may be a slit yarn obtained by slitting various components having the above-described metal luster, and may be a twisted yarn obtained by twisting the slit yarn with another yarn. You may.

The short fibers forming the sheath yarn of the glittering spun yarn of the present invention have the role of coating the metallic luster yarn as the core yarn to soften the texture of the glittering spun yarn, but the core yarn is completely Instead, the core yarn is exposed at random and moderately, and plays a role of exhibiting soft glitter and antibacterial properties of glittering spun yarn.

The short fiber forming the sheath yarn is not particularly limited as long as it is a short fiber conventionally used for a spun yarn and can soften the texture of glittering spun yarn. Cotton yarn, wool yarn, hemp yarn, silk yarn, Soup or the like can be used alone or a mixture of these can be used.

The glittering spun yarn of the present invention can be obtained by spinning a metal luster yarn as a core yarn and a roving spun short fiber as a sheath yarn. The thickness of the glittering spinning yarn is not particularly limited and may be appropriately determined depending on the fiber product to be used, but when used for general fiber products, it is preferably 10 to 50 counts when converted to cotton count. A thickness of about 30 to 40 counts is more practical and preferable. When spinning a glittering spinning yarn, the glittering spinning yarn is often twisted as a whole to improve the strength of the glittering spinning yarn. At this time, the twist processing conditions such as the number of twists are such that the twist coefficient (a numerical value associated with the thickness of the twisted yarn and the number of twists), which generally indicates the strength of the twist, is 1.3 to 6.5. It is preferable to adjust so as to be in the range of, depending on the type of short fiber, the slit width and mixing ratio of the metallic glossy yarn described later, the thickness of the glittering spinning yarn, the type of fiber product using the glittering spinning yarn, etc. What is necessary is just to adjust suitably so that it may be in the said range.

In the glittering spun yarn of the present invention, the metallic glossy yarn as the core yarn is not completely covered with the short fibers as the sheath yarn, and the metallic glossy yarns are randomly and appropriately exposed from the short fibers. Shall be done. To explain this in more detail,
In the spun yarn described in JP-A-2000-54234, the short fiber group is in a dense state, that is, the short fiber group is in a tight state, and there is no gap in the short fiber group. Since the metallic luster yarn was covered with the fiber group, the luster yarn was completely covered, and as a result, the luster yarn was not exposed at all. Because the short fibers are in a sparse state, that is, the short fibers are loosely tightened, a random and appropriate gap is formed in the short fibers, and the metal fibers are covered with the short fibers in such a state. Therefore, the metallic glossy yarn is not completely covered, and as a result, the metallic glossy yarn is randomly and appropriately exposed from the gaps of the short fibers. By doing so, the glittering spun yarn of the present invention can obtain soft glittering properties, antibacterial properties, and a soft texture, and textile products using the glittering spun yarns also have a soft texture. Brightness, antibacterial properties, and good touch can be obtained. And
The glittering spinning yarn of the present invention and the fiber product using the same can obtain the above-mentioned features and effects by simultaneously controlling the thickness of the metallic glossy yarn and the mixing ratio of the metallic glossy yarn.

The thickness of the metallic luster yarn corresponds to the slit width of the metallic luster yarn. The slit width of the metallic luster yarn is 0.19 (160 cuts) or more in order to obtain the above-mentioned features and effects.
0.13 mm (230 cuts) is preferable, and 0.17 (180 cuts) to 0.14 mm (220 cuts) is more preferable.
It is. If the slit width of the metallic luster yarn is smaller than 0.13 mm, it is not preferable because the yarn breaks during slitting of the luster yarn or spinning of the glittering spinning yarn. If the slit width of the metallic luster yarn is wider than 0.19 mm, the core luster yarn becomes difficult to be covered with the sheath yarn as a short fiber in a well-balanced manner. During the weaving of textile products using woven fabrics, metallic luster yarns are linearly exposed in the length direction at various locations of glittering spinning yarns, and as a result, textile products using such glittering spinning yarns have a soft touch. This is not preferred because the quality of the film deteriorates and the design property deteriorates. This is because the shape of the slit yarn, which is the metallic luster yarn, is flat, so that the metallic luster yarn and the sheath yarn covering the same tend to shift. It becomes more remarkable. Therefore, the slit width is 0.19 mm
If the width is wider, the occurrence of a shift between the metallic glossy yarn and the sheath yarn becomes remarkable, and even if the mixing ratio of the metallic glossy yarn described later is controlled, the occurrence of the shift cannot be prevented.

Further, in order for the glittering spinning yarn and the fiber product using the same to obtain the above-mentioned features and effects, it is necessary to control the slit width of the metallic glossy yarn and simultaneously adjust the mixing ratio of the metallic glossy yarn as described above. Control is required. Here, the mixing ratio of the metallic glossy yarn means the weight percentage of the metallic glossy yarn in the glittering spinning yarn. In order to obtain the above features and effects, the mixing ratio of the metallic luster yarn is preferably in the range of 10 to 40%,
It is more preferable to set the range of 15 to 35%. When the mixing ratio of the metallic luster yarn is lower than 10%, the metallic luster yarn serving as the core yarn is more likely to be completely covered with the short fibers serving as the sheath yarn. As a result, the glittering spun yarn and textile products using the same This is not preferred because the appearance of brilliancy and antimicrobial properties is easily inhibited. If the mixing ratio of the metallic luster yarn is higher than 40%, the metallic luster yarn as the core yarn becomes difficult to be sufficiently covered with the short yarn as the sheath yarn, and as a result, the luster of the glittering spun yarn becomes brilliant. This is not preferable because the texture becomes hard and the glittering spinning itself becomes difficult in some cases. Further, textile products using glittering spinning are not preferred because glittering becomes brilliant or the skin feels worse. Therefore, the mixing ratio of the metallic luster yarn is
In order to obtain soft glitter, antibacterial properties and soft texture of glitter spinning, and to obtain soft glitter, antibacterial properties and good touch of textile products using glitter spinning, -40% is preferable, and 15-35%
% Is perfect. As described above, by simultaneously controlling the thickness of the metallic luster yarn and the mixing ratio of the metallic luster yarn, the glitter spinning yarn of the present invention and a fiber product using the same can be obtained for the first time.

The textile product using the glittering spinning yarn of the present invention has a soft glittering effect on the entire fiber product, but it is of course possible to apply a glittering glittering effect of metallic luster to any part. For example, if the short fibers of the sheath yarn are removed by opal processing or the like in a pattern pattern from an arbitrary part of the textile product using the glittering spinning, metal is added to a part of the textile product that has soft glitter on the whole. It becomes a textile product with a glossy design and excellent decorativeness.
