[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brilliant spun yarn using a metallic luster yarn, and a fiber product using the same. More specifically, it has a soft brilliant property and a soft texture. In addition, it is used for glittering spun yarns that are also excellent in antibacterial properties, and textile products using them, especially for products that come into direct contact with the skin, such as underwear, socks, pantyhose, towels, baby clothes, sweaters, and linings for clothes. Also, the present invention relates to a textile product which has no tingling sensation, is excellent in touch, and has soft luster and antibacterial properties.

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

Further, there is known a spun yarn in which a metallic luster yarn having a metal thin film layer formed on at least a plastic film is used as a core yarn and a short fiber is used as a sheath yarn. For example, JP 20
JP-A-00-54234 discloses a spun-twisted yarn in which a metallic luster yarn obtained by slitting a laminate including at least a base material and a metal thin film layer is used as a core yarn, and a short fiber group is used as a sheath yarn, and There is described a fabric in which a staple fiber group, which is a sheath yarn, is removed by opalizing the used fabric, and a core yarn is exposed at an arbitrary portion.

[0004]

However, the conventional flat gold silver yarns, twisted gold silver yarns, and fiber products using them have the following drawbacks. Since the conventional flat gold and silver threads and twisted gold and silver threads have many exposed parts of the gold and silver threads, they have a metallic luster and a glittering glittering property, and do not have a soft (calming) glittering property.
Therefore, the fiber products using the conventional flat gold and silver yarns and twisted gold and silver yarns also have a glittering glittering property, and a soft glittering property cannot be obtained. In addition, conventional flat gold silver threads and twisted gold silver threads have a hard texture as a whole, so in the case of textile products using them, such as underwear, socks, and towels, which come into direct contact with the skin, they touch the skin. There was a tingling sensation, and the so-called skin feel was uncomfortable.

Further, the spun-twisted yarn described in JP-A-2000-54234 and the cloth using the same have the following drawbacks. The spun-twisted yarn did not have brilliance at all because 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 tightly tightened, no gap is formed in the sheath yarn, and the sheath yarn in such a state is used for the metallic luster yarn. Since the core yarn is 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 glitter. Therefore,
As a matter of course, the cloth using the spun and twisted yarn does not have any glitter as it is. If it is attempted to bring out the luster in a fabric using spun and twisted yarns, the short yarn group that is the sheath yarn is removed by opal processing as described in the above publication to form the core yarn. It has to be revealed in an arbitrary portion, and in this case, the flashy glittering property appears only in the optional portion from which the short fiber group is removed, and the entire fabric does not have a soft glittering property. Even if the metallic glossy thread, which is the core thread, has an antibacterial property, it is completely covered with the sheath thread composed of the short fiber group, and the metallic glossy thread is not exposed at all, so the antibacterial property is not exhibited. Therefore, the fabric using it did not have any antibacterial property at all.

The present invention eliminates all of the above-mentioned drawbacks, and has a brilliant spun yarn having a soft brilliance, a soft texture and an excellent antibacterial property, and a fiber product using the brilliant spun yarn. The present invention provides a fiber product which has a soft glittering property, is excellent in touch, and has excellent antibacterial properties.

[0007]

(1) According to the present invention, in a spun yarn in which at least a metallic glossy yarn having a metal thin film layer formed on a plastic film is used as a core yarn and a short fiber is a sheath yarn, the core yarn is The glittering spun yarn is characterized in that the core yarn is not completely covered with the sheath yarn and the core yarn is exposed at random. (2) The present invention is the bright spinning fiber according to (1) above, 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 fiber product characterized by using the glittering spun yarn according to the above (1) or (2).

The glitter spun yarn of the present invention is a spun yarn 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 as a sheath yarn.
Since the core yarn is not completely covered with the sheath yarn and the core yarn is exposed randomly and appropriately, as a result, it has a soft glittering property. Therefore, the fiber product using the glitter spinning of the present invention also has a soft glitter property not in an arbitrary part of the fiber product but in the entire fiber product.

Further, since the glittering spun yarn of the present invention is a spun yarn in which the metallic luster yarn is the core yarn and the short fibers are the sheath yarn, it has a hard texture like conventional flat gold silver yarn and twisted gold silver yarn. Since it is soft, the textile product using the glittering spun yarn does not have a tingling sensation when it comes into contact with the skin, and has a so-called soft feel, so that underwear, socks, pantyhose, towels, baby clothes, sweaters, lining of clothes, etc. It can now be fully used for products that directly touch the skin like.

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

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The metallic luster yarn, which is the core yarn of the glittering spun yarn of the present invention, has a metal thin film layer formed on at least a plastic film. It also imparts antibacterial properties.

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

The thickness of the plastic film is 3 to 25.
μm is preferable, 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 luster 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 has a metallic luster when the metal thin film layer is formed using the metal, and for example, Al, Sn , Ni, Cr, Zn, Au, Ag, Cu and the like can be used, and particularly when the metal thin film layer is formed by using Ag or Cu having antibacterial properties, the glitter spinning is imparted with the glitter. Excellent antibacterial properties can also be imparted.

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

The metallic luster yarn, which is the core yarn of the glittering spun yarn of the present invention, has only to have a structure in which a metal thin film layer is formed on at least a plastic film, for example, a metal thin film layer is formed directly on one side of a plastic film. On the metal thin film layer for the purpose of surface protection and the like, a structure in which an anchor layer is formed between the plastic film and the metal thin film layer for the purpose of improving adhesion, heat resistance, corrosion resistance, etc. Examples thereof include a structure in which a top coat layer is formed, 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 topcoat layer for the purpose of improving antibacterial property, or a dye or a 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,
It may have a structure in which the metal thin film layer side is placed inside and is bonded with an adhesive or the like, or a structure in which this is combined with an anchor layer or a top coat layer as described above. The metallic luster yarn may be a slit yarn obtained by slitting various constituents having the above metallic luster, and is a twisted yarn obtained by twisting the slit yarn and another yarn. May be.

The short fibers forming the sheath yarn of the glittering spun yarn of the present invention have a role of covering the metallic luster yarn which is the core yarn and softening the texture of the glittering spun yarn, but the core yarn is completely It does not cover the core yarns at random, but appropriately exposes the core yarns, and plays the role of revealing the soft glittering property and antibacterial property of the glittering spun yarn.

The short fibers forming the sheath yarn are short fibers conventionally used in spun yarn, and are not particularly limited as long as they soften the texture of the glittering spun yarn, and include cotton yarn, wool yarn, hemp yarn, silk yarn, A single material such as soup or a mixture of these materials can be used.

The glittering spun yarn of the present invention can be obtained by spinning a metallic luster yarn as a core yarn and a roving short fiber as a sheath yarn. The thickness of the glitter 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 when converted to cotton count, A thickness of about 30 to 40 is more practical and preferable. During spinning of the glittering spun yarn, the entire glittering spun yarn is often twisted in order to improve the strength of the glittering spun yarn. At this time, the twisting conditions such as the number of twists are such that the twisting coefficient (a numerical value associated with the thickness of the yarn to be twisted and the number of twists), which is generally expressed as 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 the short fibers, the slit width and the mixing ratio of the metallic glossy yarn described later, the thickness of the glittering spun yarn, the type of the textile product using the glittering spun yarn, etc. It may be appropriately adjusted so as to be within the above range.

In the glittering spun yarn of the present invention, the metallic luster yarn which is the core yarn is not completely covered with the short fiber which is the sheath yarn, and the metallic luster yarn is randomly and moderately exposed from the short fiber. It is assumed that 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 tightly tightened state, and no gap is formed in the short fiber group. Since the metallic glossy yarn was completely covered with the fiber group, the metallic glossy yarn was completely covered, and as a result, the metallic glossy yarn was not exposed at all, whereas the glittering spun yarn of the present invention was used. The short fibers are in a sparse state, that is, the short fibers are loosely tightened.Therefore, a short and appropriate gap is created in the short fibers, and the short fibers in such a state cover the metallic luster thread. Therefore, the metallic glossy yarns are not completely covered, and as a result, the metallic glossy yarns are randomly and appropriately exposed from the gaps between the short fibers. By doing so, the glittering spun yarn of the present invention can obtain a soft glittering property, an antibacterial property, and a soft texture, and a textile product using the glittering spun yarn is also soft. It is possible to obtain glitter, antibacterial properties, and good touch. And
The glitter spun 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 luster yarn and the mixing ratio of the metallic luster yarn.

The thickness of the metallic glossy thread corresponds to the slit width of the metallic glossy thread. The slit width of the metallic luster thread is 0.19 (160 cut) to obtain the above features and effects.
0.13 mm (cut by 230) is preferable, and more preferably 0.17 (cut by 180) to 0.14 mm (cut by 220).
Is. If the slit width of the metallic glossy thread is smaller than 0.13 mm, thread breakage may occur during slitting of the metallic glossy thread or during spinning of the glitter spun yarn. When the slit width of the metallic glossy thread is wider than 0.19 mm, it becomes difficult to cover the metallic glossy thread which is the core thread with the short fiber which is the sheath thread in a well-balanced manner. At the time of weaving a textile product using, the metallic luster yarn is exposed linearly in the longitudinal direction at the locations of the glittering spun yarn, and as a result, the textile product using such glittering spun yarn feels soft to the touch. Is deteriorated and the designability is deteriorated, which is not preferable. This is because the slit yarn, which is a metallic luster yarn, has a flat shape, so that the metallic luster yarn and the sheath yarn that covers it are easily displaced. It becomes remarkable. Therefore, the slit width is 0.19 mm
If it is wider, the occurrence of the deviation between the metallic glossy thread and the sheath thread becomes remarkable, and the occurrence of the deviation cannot be prevented even by controlling the mixing ratio of the metallic glossy thread described in detail later.

Further, in order to obtain the above-mentioned features and effects of the glittering spun yarn and the fiber product using the same, it is necessary to control the slit width of the metallic glossy yarn and to control the mixing ratio of the metallic glossy yarn as described above. Control is needed. Here, the mixing ratio of the metallic glossy yarn means the weight% of the metallic glossy yarn in the glittering spun yarn. In order to obtain the above features and effects, the mixing ratio of the metallic glossy yarn is preferably in the range of 10 to 40%,
It is more preferable to set it in the range of 15 to 35%. When the mixing ratio of the metallic luster yarn is lower than 10%, the metallic luster yarn which is the core yarn is likely to be completely covered with the short fiber which is the sheath yarn, and as a result, the glittering spun yarn and the fiber product using the same. It is not preferable because the luster and the appearance of antibacterial properties are easily impaired. When the mixing ratio of the metallic glossy yarn is higher than 40%, it becomes difficult for the metallic glossy yarn as the core yarn to be sufficiently covered with the short fibers as the sheath yarn, and as a result, the glittering property of the glittering spun yarn becomes flicker. Or, the texture becomes hard, and in some cases, the spinning of the glittering spun yarn itself becomes difficult, which is not preferable. Further, a fiber product using the glittering spun yarn is also not preferable because the glittering property becomes flicker or the touch becomes poor. Therefore, the mixing ratio of metallic glossy yarn is
In order to obtain the soft brilliance, antibacterial property, and soft texture of the brilliant spun yarn, and to obtain the soft brilliance, antibacterial property, and good feel of the fiber product using the brilliant spun yarn, 10 Is preferably in the range of 40% to 15%
% Is more 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 fiber of the present invention and the fiber product using the same can be obtained for the first time.

The fiber product using the glittering spun yarn of the present invention has a soft glittering property to the entire fiber product, but it is of course possible to give a lustrous glittering property of metallic luster to an arbitrary portion. For example, if the short fiber of the sheath yarn is removed by opal processing etc. in a pattern pattern on an arbitrary part of the fiber product using the glittering spun yarn, a metal product is partially formed on the fiber product having a soft glittering property as a whole. A textile product with a glossy pattern and excellent decorativeness.
