Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a design yarn obtained by twisting a metal-deposited slit yarn having gloss and a spun yarn made of another fiber. More specifically, the present invention relates to a design yarn that can take various color tones and colors by dyeing.

[0002]

[Prior Art]

 Slit yarn (so-called lame yarn) made of metal vapor-deposited film has a beautiful luster and color tone, and has been used for a long time as a fiber material that imparts a different luster or different color effect to textile products.

[0003] Some of the lame yarns are uncolored ones in which the color of the vapor-deposited metal is expressed as it is, and some are colored after the metal vapor deposition. These lamé yarns are used as gold and silver design yarns by being mixed or twisted with other yarns as needed.

For example, a spun yarn (animal wool yarn) such as wool yarn and a lame yarn are combined and twisted to make a design yarn in which a portion having a metallic luster is scattered, and this is used as a knitted product such as a sweater. There is a way to finish it, and polyester film has been preferably used as the base material of this lame yarn.

When such a design yarn is manufactured from a dyed animal wool yarn and a lame yarn, the final product is finished by weaving and knitting without post-processing such as dyeing.

[0006] In the case of a design yarn produced from undyed animal wool yarn and lame yarn, it may be dyed and then finished into a final product, or dyed after finishing into a product such as a sweater. There is also the so-called product dyeing.

However, in any case, since the polyester lame yarn is not dyed by the atmospheric dyeing for dyeing animal wool, it has been used as a product to obtain a different color effect and a gold-silver thread effect. It was

[0008] Even when it is desired to make the lamé yarn in the design yarn a color tone of the same type as the animal wool yarn, the polyester lamellar yarn cannot be dyed at the same time as the animal wool yarn, so the lamellar yarn previously colored in that color tone is selected and used. I had no choice but to take the method.

[0009]

[Problems to be solved by the device]

 However, polyester lame yarns are not dyed by atmospheric dyeing for dyeing sweaters made from animal wool yarns. Therefore, in the conventional lame yarn mixed design yarns, the contrast between animal wool yarns and lame yarns is deeply emphasized, or It is often unsuitable for use as the ground yarn of products because the effect of discoloration is too strong, and rather, it has always been used for decorative patterns, and it is used as a ground yarn prepared design yarn that gives an elegant luster. It was often unsuitable for

In addition, there is a case where a yarn dyed lame yarn is used in order to make the color tone the same as that of the ground yarn, but since the film is undiluted or dyed, the cost is high, the color tone does not match, the color tone can be freely selected, and the marketability is improved. There was a defect such as damage.

Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and enables color adjustment without being constrained by the original color tone of lame yarn. Its main purpose is to provide a design yarn that is mixed with lame yarn and can make a difference.

That is, even if the lame yarn has a limited color or no coloring, it gives a lame yarn effect of a color tone matching the color of the animal wool of the base, or a lame yarn having a different color effect and a gold-silver effect. The purpose is to provide a design thread that can be adjusted.

Another object is to provide a designed yarn that can be dyed without deteriorating the yarn form.

[0014]

[Means for Solving the Problems]

 In order to achieve this object, the design yarn of the present invention comprises a spun yarn composed mainly of animal fiber and a slit yarn composed of a metallized polyamide film in a direction opposite to the twist direction of the spun yarn. It is characterized in that the spun yarn and the slit yarn are both twisted and dyed.

The spun yarn based on the design yarn of the present invention is a spun yarn mainly composed of animal hair fiber, for example, a spun yarn composed of only one kind of animal hair fiber such as wool, angora, cashmere and mohair. A spun yarn obtained by mixing a plurality of these animal hair fibers, and a mixed yarn obtained by mainly mixing these animal hair fibers with a small amount of another fiber such as polyamide fiber can be mentioned. This spun yarn may be used as a single yarn, or may be used as a double yarn, a triple twist, a four twist, and the like.

The lame thread used in the present invention is a thread obtained by cutting a metal vapor-deposited polyamide film, particularly preferably a multi-layered film having a metal vapor-deposited surface further covered with a polyamide film, into thin strips. Generally, it is called nylon lame thread. Hereinafter, this is referred to as nylon lame thread.

In general, this nylon lame yarn has a vapor-deposited layer of a metal such as aluminum, silver, or gold formed on a surface of a polyamide film as thin as 5 to 50 μm by a vacuum vapor deposition method. It is manufactured by cutting into a narrow width such as 1 to 1.0 mm and forming a slit thread.

In this manufacturing process, the metal-vapor-deposited polyamide film may be laminated with another polyamide film on the metal-vapor-deposited surface in order to improve the durability of the metal-vapor-deposited layer, and the purpose of the present invention. Preferred for dyeing lame yarns. The metal vapor-deposited polyamide film may be further laminated with another polyamide film on the surface opposite to the metal vapor-deposited surface.

The nylon lame yarn produced from the film having such a multilayer structure has a multilayer structure as shown in FIG. 2, for example. FIG. 2 shows a cross-sectional view of a nylon lame yarn from a three-layer film, which is laminated onto a metal vapor-deposited polyamide film layer (11) and its metal-deposited surfaces (12) and (12 '), respectively. And another polyimide film layer (13), (14).

Examples of the polyamide forming the base film include polyhexamethylene adipamide (nylon 66), poly ε-capramide (nylon 6), and polyamides containing these as the main components.

The spun yarn as a base and the nylon lame yarn are aligned and twisted, and the twisting direction is the twisting direction of the spun yarn (= the twisting direction in the case of a single yarn, the twisting direction in the case of a twin yarn, etc. It is necessary to reverse the direction of the upper twist. The ply twisting is preferably performed with the number of twists such that the twist (upper twist) of the spun yarn remains appropriately.

This twisting may be performed by a method in which spun yarn and nylon lame yarn are aligned and twisted. At that time, the yarns may be aligned without any difference in yarn length, or may be twisted by wall twist with a difference in yarn length. Alternatively, a spun yarn may be used as a core and covered with nylon lame yarn.

At the time of this twisting, other yarns such as polyamide filament yarn may be mixed as long as the yarn amount and the color tone of the final design yarn are not adversely affected.

The design yarn obtained by ply-twisting is dyed with a dye capable of dyeing both animal hair fiber and nylon lame yarn. The dye is preferably an acid dye, but may be another dye. The dyeing is preferably carried out using an acid dye of the type usually used for dyeing polyamide fibers and wool fibers and the dyeing conditions. Examples of the type of acid dye include acid dyes (in a narrow sense), metal complex salt dyes, and acid mordant dyes.

The dyeing may be yarn dyeing performed at the design yarn stage, or may be post-dying or product dyeing after dyeing after knitting or knitting or sewing.

The design yarn of the present invention obtained in this manner has a yarn constitution as schematically shown in FIG. FIG. 1 illustrates a design yarn obtained by ply twisting one spun yarn (1) of twin yarns and one nylon lame yarn (2).

[0027]

[Action]

 Since the design yarn of the present invention uses a nylon lame yarn having a polyamide film as a base material, the nylon lame yarn can be dyed simultaneously with the dyeing of the spun yarn of animal hair fiber which is the base of the design yarn.

Therefore, the color tone of the nylon lame yarn can be arbitrarily adjusted by dyeing. For example, by dyeing nylon lamellar yarn with a color tone similar to or similar to that of spun yarn, the glittering luster of the nylon lamellar yarn can be suppressed, and a product with a calm and elegant color tone can be obtained.

If a plurality of mixed dyes having different dyeing speeds are used in the same dyeing bath, nylon lame yarns and spun yarns are made different by utilizing the difference in dyeing speed between polyamide film and animal hair fiber. It is also possible to dye with a different color tone, and it is also possible to impart a different color effect by dyeing.

[0030]

【Example】

 [Example 1] As a spun yarn forming the base of the design yarn, a No. 32 wool worsted yarn obtained by twisting two No. 32 wool yarns twisted in the Z direction at 200 t / m in the S direction was used.

As the lame yarn, a 0.25 mm wide nylon lame yarn manufactured from a non-colored nylon 6 film (thickness 40 μm) having a three-layer structure in which an aluminum-deposited nylon 6 film is used. .

Each of the wool worsted yarn and the nylon lame yarn was aligned, and 170 t / m of Z twist was plied with a ring twister to produce a design yarn.

The obtained design yarn is scoured by the usual scouring method for wool spun yarn, dyed with an acid dye under the following dyeing conditions, and subjected to a fixing treatment, and then euling treatment according to the usual euling method for wool spun yarn. The dyed design yarn. (Composition of dye bath) "Polar Red NBH" (manufactured by Nippon Kayaku Co., Ltd.) 1.5% owf. "Scarlet FGW" (manufactured by Nippon Kayaku Co., Ltd.) 1.0% owf. "Alvegar A" (Manufactured by Sand Co., Ltd.) 0.5% owf. Acetic acid 1.0% owf. (Dyeing temperature condition) 50 ° C → temperature increase (30 minutes) → 100 ° C (30 minutes) → water washing (fix treatment condition) "Spacidol FW "(made by Morin Chemical Co., Ltd.) 3% owf.

With respect to the dyed design yarn, both the wool spun yarn and the nylon lame yarn were dyed in the same type of red color and had an elegant lame yarn effect.

When the obtained knitted design yarn was used as the ground yarn and a knitted flat knitted 7-gauge satin knitting machine was knitted by a usual method, the resulting sweater had no glittering luster of the original lame yarn. The product has a calm, elegant and elegant color tone and luster. [Comparative Example 1] The same procedure as in Example 1 was carried out except that a slit yarn having a width of 0.25 mm and made of a non-colored polyethylene terephthalate film (2 layers) having a thickness of 24 μm vapor-deposited on aluminum was used as the lame yarn. , A design yarn was manufactured and dyed.

In the design yarn obtained by dyeing, the wool spun yarn was dyed in a good color tone, but the lame yarn was not dyed at all.

When a sweater was knitted from this dyed design yarn, it was a product having a strong contrast between the wool spun yarn and the lame yarn, and having a dazzling gloss.

[0038]

[Effect of the device]

 Since the spun yarn and the lame yarn forming the base can have the same color tone by dyeing, the design yarn of the present invention can produce a subtle product tone.

Further, the one-bath dyeing makes it possible to make the lame yarn have a color tone that matches the color of the spun yarn as the base, so that the lame yarn can be used for general purposes.

Further, it is possible to make a design yarn having a different color effect by dyeing.

Furthermore, the yarn can be dyed without deteriorating the yarn form of the design yarn.

Therefore, the design yarn of the present invention can exhibit a wide range of different luster and different colors, and is therefore suitable for clothing products such as sweaters. In addition, since it can be dyed without deteriorating the yarn form, it can also be used as a pattern yarn for producing an overall pattern or point pattern by weaving and knitting.
