DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretchable design yarn comprising a combination of an elastic yarn and a foil yarn.

[0002]

2. Description of the Related Art It has been considered that conventional foil yarns, such as gold and silver yarns and lame yarns, cannot be manufactured if they are stretched, because when they are stretched, the foils crack and lose their luster.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to make such a gold-silver thread or the like widely usable as a design thread having high elasticity for various uses.

[0004]

Means for Solving the Problems The designed yarn of the present invention comprises a)
An elastic yarn is used as a core yarn, and in a state where the core yarn is stretched to a certain length, a foil yarn is wound around the core yarn in one direction (twisting), and then another yarn (plain yarn) is turned in the opposite direction. Or b) in a state where the elastic yarn is stretched to a certain length and aligned with a foil yarn to form a core yarn, and another yarn is wound around this core yarn.

[0005] This product becomes a stretchable design yarn in which a foil yarn forms a loop around the elastic yarn in a state where the elastic yarn used as the core yarn is released.

It may be used in the form of a single yarn as it is, or may be used by twisting two or more yarns.
Good quality in any form such as race, lily yan, etc.
It can be used while maintaining elasticity. Therefore, according to the present invention, a supporter, a wristband, a leotard, a swimsuit, a sweater, a skirt, a hair band, and the like, which are rich in design and stretchability (fitness), can be easily manufactured.

[0007] In particular, it is preferable to use at least one of the design yarns a) and b) as a lily yarn (braided cord) {an elastic decorative cord}. This lilyarn can be used for hair bands, ribbons, wrapping bands and the like as it is or as a woven fabric.

As the elastic yarn serving as the core yarn of the design yarn, any of elastic yarns having rubber elasticity can be used. In particular, the material is not limited, but a yarn made of polyurethane fiber is usually used. Is preferred.

In general, the thickness of the elastic yarn is preferably about 7 to 1000 denier. If the thickness is less than 7 denier, the strength is weak, yarn breakage tends to occur, and twisting becomes difficult. On the other hand, if the thickness is larger than 1000 denier, the strength becomes too strong, and the feeling becomes poor. It is particularly preferred that it is about 10 to 300 denier.

[0010] Next, as the foil yarn used by winding such an elastic yarn in a stretched state, or by pulling it together, slit yarn of a colored or uncolored plastic film, flat foil yarn, or a combination of these. Any of the used twisted gold-silver yarns (for example, twisted gold-silver yarns such as haori twist, cross twist, round twist, bellows twist, entangle twist, etc.) can be used.

Although the thickness of the foil yarn is not particularly limited, slit yarn or flat foil yarn (hereinafter referred to as slit yarn, etc.)
Is generally used, a thickness of about 3 to 30 μm and a width of about 0.
It is easy to handle about 15 to 10 mm, especially thickness 7 to
It is preferable that the thickness is about 25 μm and the width is about 0.16 to 3.3 mm. If the thickness is less than 3 μm, it is too thin, and the slit yarn or the like is easily stretched at the time of twisting. Also, if the width is less than 0.15mm,
It is too thin, and slit yarns etc. are easy to stretch during twisting.
If it is wider than mm, it will be too wide and difficult to handle, and the hand will be bad.

Further, in the state where the elastic yarn is stretched, the yarn wound in the opposite direction from the top of the foil yarn wound around the elastic yarn, or the yarn wound around the core yarn in which the stretched elastic yarn and the foil yarn are aligned. Since it is for preventing the displacement of the foil yarn and at the same time restricting the elongation of the elastic yarn, the yarn is preferably substantially non-stretchable. The type of fiber may be any of natural fiber, semi-synthetic fiber, and synthetic fiber, and may be short fiber or long fiber, but usually, polyamide fiber, polyester fiber, acrylic fiber It is preferable to use fiber, rayon fiber and the like. In particular, use of long fibers is preferred.

In the twisting method, in the case of the design yarn of a), the foil yarn and other yarns are preferably wound in a state where the elastic yarn is stretched 1.1 to 5.0 times. If the elongation percentage is less than 1.1, twisting is difficult, and the loop formation of the foil yarn is not enough. Conversely, if it is greater than 5.0, the elongation percentage is too large, and twisting is also difficult. The loops of the foil yarn become too large and are easily caught and difficult to handle. Further, in the case of the design yarn of b), it is preferable that the elastic yarn is stretched to about 1.5 to 5.0 times, the foil yarn is aligned, and another yarn is wound thereon. In any case, the stretched state of the elastic yarn at the time of twisting is preferably about 1.5 to 3.5 times.

In the case of the design yarn of a), the number of windings (twisting number) of the foil yarn around the elastic yarn differs depending on the stretched state of the elastic yarn and the thickness of the elastic yarn or the foil yarn. In the state,
Usually, it is preferably 50 to 1500 T / M. When the number of times is less than 50 T / M or more than 1500 T / M, the number of loops formed by the foil yarn is too small or too large, and it is difficult for the loops to appear on average.
It is difficult to obtain products with good texture. A particularly preferred number of twists is 100
６００600 T / M.

Next, the number of windings (twisting number) of the other yarns wound in the opposite direction to the foil yarns from above the foil yarns in a state where the elastic yarns are stretched is 100 to 2000 T / M. Is preferred. If it is less than 100 T / M, it will not be reinforced, the foil thread will not be fixed, it will be easy to move in the longitudinal direction, and it will not be possible to obtain a good feeling. Conversely, 2000T / M
If the number is too large, the loops of the other yarns are too large, they are not fixed, easily move in the longitudinal direction, do not serve as reinforcement, and it is difficult to obtain a good feeling. A particularly preferred number of twists is 20
0 to 600 T / M. In addition, the number of twists of other yarns, which is useful for fixing the loop of the foil yarn, is usually equal to or more than the number of twists of the foil yarn, for example, preferably about 1 to 13 times the number of twists of the foil yarn, In particular, it is preferably about 1.2 to 5 times.

In the case of the design yarn of b), the number of twists of the other yarn wound around the core yarn composed of the elastic yarn in the stretched state and the foil yarn aligned with it is about 100 to 1000 T / M. preferable.

Generally, in any of the design yarns a) and b), the thickness of the foil yarn used together with the elastic yarn is the same as the thickness of the elastic yarn in the stretched state when the foil yarn is wound or aligned. On the other hand, it is preferably about 0.5 to 6 times in terms of denier. Also, the thickness of the other yarn wound from above,
The thickness is preferably about 0.5 to 10 times the thickness of the elastic yarn in the stretched state.

In the present invention, it is preferable to use such a design yarn as a knitted string or a lily yarn knitted with, for example, 2 to 10 needles. Although it may be produced in combination with other yarns such as cotton yarn, rayon yarn and acrylic yarn, it is preferable to produce the design yarn of the present invention alone from the viewpoint of both feeling and elasticity.

[0019]

Next, the present invention will be described in more detail with reference to examples. Example 1 A 70-denier elastic yarn (polyurethane yarn from Toray DuPont: Operon) stretched 2.5 times (the thickness of the yarn in the stretched state is approximately 28 denier), and a foil yarn of approximately 61 denier (with a thickness of approximately 28 denier). 50 on 12 μm thick polyester film
0.38 mm wide silver flat foil with a 0 mm thick aluminum vapor deposition layer and a 1.5 μm thick melamine resin protective layer)
Was twisted right at a twist of 200 T / M, and a 50-denier nylon yarn was twisted leftward at a twist of 400 T / M from above.
The stretched state of the elastic yarn was released to obtain a design yarn with high elasticity in which a loop of silver foil yarn was uniformly formed on the whole.

Example 2 A slit yarn having a thickness of 15 μm and a width of 0.25 mm made of a transparent nylon film was used as a foil yarn.
The design yarn of the present invention was produced in the same manner as in Example 1.

Example 3 The designed yarn obtained in Example 1 was produced into a two-needle liliyaan A and a four-needle liliyaan B. Both Lilyan A and B were elastic and rich in metallic luster. Lilyan A has a very soft feel, and can be woven and knitted to be used widely as various clothings, hair bands, and the like. Lilyan B was also woven and knitted and could be used widely, but could be used directly with good design as a highly elastic hair-clasping string or packaging band. In addition, it could be used efficiently as a narrow-width fabric and as a wristband and a supporter.

Example 4 The design yarn of Example 2 was produced in a four-needle lily yarn and dyed in various colors with an acid dye. As a result, good feeling, rich elasticity, rubber elastic cords of various colors are obtained, and by weaving the cords into narrow fabrics, rich in design,
An easy-to-handle and elastic ribbon tape was obtained.

Example 5 A 140-denier elastic yarn (polyurethane yarn from Toray DuPont: operon) stretched 3.5 times, and this was aligned with a foil yarn to form a core yarn. Was twisted to the right with a twist number of 300 T / M. The foil yarn is obtained by forming an anchor coat layer of a polyester resin on a nylon film having a thickness of 15 μm, and forming a tin vapor deposition layer having a thickness of 450 mm on the anchor coat layer.
The sheets were stuck together with a polyester resin-based adhesive with the tin evaporation layer inside, and a flat foil thread slit to a width of 0.38 mm was used. The product obtained in this manner is a stretchy design yarn in which the loop of silver foil yarn is formed uniformly over the whole in a state where the elastic yarn has been released, and like the design yarn of Example 1, As a stretchable lily yan or directly woven and knitted, it can be widely used for stretchable clothing and the like.

Example 6 A method similar to that of Example 1 was carried out except that a twisted gold-silver yarn obtained by twisting the flat foil yarn of Example 1 with a nylon yarn and a garment was used as the foil yarn. This product is a highly elastic design yarn in which silver foil thread loops are formed uniformly over the entire surface. It has a voluminous feel and is excellent in both cushioning and feeling as compared with the product of Example 1. Was.

[0025]

According to the present invention, it is possible to easily provide a lame yarn-like design yarn having high elasticity. This design yarn can be directly used for a part of the weaving and knitting structure to produce a body-fitting and easy-to-wear garment. In addition, the woven or knitted fabric or lace using the design yarn is very easy to handle as an elastic packaging material having excellent design properties and feeling, or as a hair band or various ribbons. The lily yarn made of the design yarn of the present invention is a soft and highly stretchable string whose surface is entirely covered with the tip of the loop of the foil yarn, and is designed for packaging or hair fastening. It can be used sexually. Also, by knitting or weaving the lily yarn in a lace shape, the product can be applied to a wide range of uses as a product having a better design and elasticity.
