Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a novel artificial fur having an iridescent color, rich in color depth and luster, and extremely aesthetically pleasing. It is something.

゛　[Problems with conventional technology] ・Artificially made from high-quality natural fur-like fabric.

Many attempts have been made to obtain this.

In general, when aiming for a natural mink look in such artificial fur, it is normal to have a two-layered structure of raised hair, which has a prickly-like appearance and a fluffy-like effect. The length of the former is 15 to 30 mm'
,, Set the latter to be within the range of about 5 to 20 mm, and set the former to be at least several mm longer than the latter,
Generally, it is made to exhibit a two-layer structure as clearly as possible.

In this way, whether natural or artificial, fur or fur-like fabrics have a raised structure with unique three-dimensionality.On the other hand, when it comes to color, natural mink fur,
Among them, those that are hailed as having an extremely high edge height include black grama mink and dark mink.
There are a wide variety of colors and varieties of mink, such as dark brown mahogany mink, light brown Lunarain mink and pastel mink, and sapphire mink, which are white-gray. In both cases, the color composition of the stinging hair and fluff is such that the stinging hair is dark in color, and the fluff color is substantially the same color as the stinging hair and is lighter than it. This relationship between the colors of the stinging hair and the downy hair is like a law of nature, and is almost unchangeable.

On the other hand, white mink fur or generally low-grade mink fur that has been bleached is used and dyed with black, etc., to achieve the same color as the ultra-high-grade mink mentioned above. Natural fur products also exist, but in these cases the prickly hair and fluff are the same color and have the same density, and are generally less beautiful and have a relatively low commercial value. □ The relationship between the color of stinging hair and fluff in the field of natural fur is as described above, but the present inventors have investigated With artificial fur, which has now reached a certain level, we have conducted intensive studies on the relative relationship between the colors of prickly hair and downy hair, which can provide a new aesthetic and color appearance not seen in conventional natural or artificial fur. As a result, we have arrived at the present invention.

In particular, since the aim is to create a fur-like appearance, the fabric structure has a remarkable three-dimensionality, so the delicate relative relationship between the colors of the embroidered hair and fluff will determine the aesthetics, overall appearance, and quality of the product. It has a surprising amount of influence on people's feelings and sense of scarcity and value.

[Purpose of the invention]

From the above-mentioned viewpoint, the purpose of the present invention is to provide a completely new artificial fur that can create a new sense of value that is extremely aesthetically rich, which is different from the beauty of high-grade mink species. Not only can the prickly hair and fluff be distinguished by color, but also when this artificial fur or this artificial fur is made into clothing, etc., the color of each part of the clothing can be changed depending on the viewing direction and angle. It has an iridescent color that looks vividly different depending on the wearer's movements, and it also has excellent color depth and gloss, which is an extremely new and unprecedented product. The aim is to provide artificial fur that is aesthetically pleasing and luxurious.

[Structure of the invention]

The artificial fur of the present invention, which achieves the above-mentioned objects, has the following configuration.

That is, it has a nape layer structure of at least two layers: a nape consisting of many long fibers and a nape consisting of short fibers, and the many short fibers have a different color between the part near the tip and the other part. The nap is composed of short fibers A, and other short fibers B having at least near the tips a color different from both the color near the tips of the short fibers A and the other parts. It features artificial fur.

[Explanation of configuration]

The term "different color in the short fiber A" as used in the present invention refers to a color in which the color of the portion near the tip of the short fiber A and the color of the other portion can be distinguished with the naked eye. Therefore, the term "different colors" refers not only to different hues such as a combination of red and green or a combination of blue and yellow, but also includes hues that have a difference in shade that can be discerned with the naked eye, even if they are the same hue.

The method of imparting such a unique color to the area near the tips of the fibers that make up the nap and other areas is as follows:
There are piece dyeing methods, yarn dyeing methods, and yarn dyeing/piece dyeing methods.

(1) After the fabric is formed, it is immersed in a dye solution, dehydrated, and dried.Then, the tip of the nap of the fabric is printed using a dye solution that has a different color. Method of coating, drying, and coloring treatment using the method (2) Iritoki Shitsudankokei (a) Line up fibers of a predetermined length and apply a dye solution that produces a different color to the center and both ends of the fibers. , drying, fixing the color, and making a raised fabric using the dyed fibers (b) Forming a fiber bundle of pre-dyed fibers, and adding a color different from the color of the central part of the fiber bundle to both ends of the fiber bundle. A method of applying a dye liquor to give a coloring treatment, or a method of applying a coloring treatment to the bundle while immersing it in this dye liquor tank (c) A method of applying a dye liquor to an undyed fiber bundle, and then applying this color A method of coloring the bundle by immersing it in a dye solution that produces a different color (3) The dyeing method involves forming a fabric with pre-dyed fibers and then using a dye solution that produces a different color from the dye. There is a method in which the tip of the nap of the fabric is coated by a printing method, dried, and colored.

In this way, by changing the concentration and blending ratio of the dye used near the tip of the fiber and the dye used in other areas, the color of the tip can be freely changed. The short fibers used in the present invention are composed of fibers dyed as follows. In other words, there is a short fiber A in which the part near the tip and the other part are different colors,
Furthermore, ■ The color of the part near the tip is different from both the color near the tip of A and the color of the other parts, but the other parts are the same color.It is made of a combination with short fiber B1. .

Or, (2) A combination of short fibers B2 in which the color of the part near the tip and the color of the other part are different from both the color of A near the tip and the color of the other part.

Furthermore, or ■ Consists of a combination of the above A, B+, and Bz.

Or, (2) a combination of the above A, B+, Bz and short fibers Bz, Ba, etc. having a different color.

etc.

When short fibers made of such a combination were evaluated with artificial fur using long fibers of the same color, the depth of color, sense of color, and aesthetics became better from ■ to ■.

Furthermore, if the color of the area near the tip and the color of the other area are different colors that are substantially complementary colors, an iridescent color will be added in addition to the depth of the color described above. Here, in the present invention, the relationship of substantially complementary colors means "
In the color scheme J (JIS-Z-8102), which shows complementary color relationships, it includes not only a specified color and the colors that are in the opposing relationship with this color, but also the colors on both sides of the colors that are in the opposing relationship with this color. shall be held. For example, if a specific color is "yellow", this "yellow" and the "blue-purple" that opposes this "yellow"
Also includes "blue" and "purple" on both sides.

When colors that are essentially complementary colors are applied to the parts near the tips of short fibers and other parts, the artificial fur, which has raised hair made of long fibers and raised hair made of short fibers, will look different depending on the viewing direction. It becomes possible to exhibit an iridescent effect.

The method of dyeing so as to have a substantially complementary color relationship is a method of dyeing according to the method of imparting different colors. However, each of the above-mentioned methods, except for method (2) (a), involves applying a dye liquor to short fibers, or applying a dye liquor having a substantially complementary color to the short fibers after dyeing. Therefore, it mixes with the previously applied or dyed color,
It may be difficult to dye the area near the tip and other areas in substantially complementary colors. In order to eliminate such color mixing, it is preferable to adopt the following method. In other words, (1) law.

In the (2) @ method, the (2) (c) method, and the (3) method, the dye solution used first is a dye that is reductively decolorized. The dye liquor used later uses a reducing agent and a reduction-resistant dye. In addition, in (2) (c) law:
It is also possible to adopt a method in which the dye liquor adhering to both ends of the fiber bundle is washed with water and then immersed in the subsequent dye liquor.

In the present invention, in order to obtain a high-quality artificial fur with a deeper color and rich luster, the vicinity of the tip of any of the short fibers A, Bs, Bz... It is preferable that the color brightness of the long fiber is smaller than the color brightness of the long fiber, and the difference in brightness (ΔL value) is at least 0.5.
It is preferable that the above difference be present, and more preferably, according to the findings of the present inventors, it is best if the above-mentioned brightness difference (ΔL value) is 2.5 or more.

By creating a relative relationship between the brightness of both fibers,
Visually, the effect is that the raised hair made of long fibers appears to cover the raised hair made of short fibers well.

By configuring it in this way, the depth and luster of the color in the overall appearance increases, and in addition,
When the wearer moves or when the wind blows, not only the long raised pilings, but also the short raised pilings, appear rich in color, giving the wearer an iridescent look. This artificial fur has an extremely aesthetically pleasing up-pillar layer that appears to change color with the movement of the skin or the breeze.

Artificial fur that has many of these effects is made by making the lightness of the color near the tip of at least one of the two or more types of short fibers of different colors smaller than the lightness of the color of the long fibers. Well, you can get it. And, more preferably, short fibers A, Bt, B exhibiting various colors.
The lightness of the color near the tip of the long fiber is greater than the lightness measured as a mixed fiber group in the mixed state forming the artificial fur.

It is preferable that the difference in brightness is at least 0.5 or more, more preferably 2.5 or more. In other words, even if the color brightness near the tip of one type of short fiber is greater than the color brightness of the long fiber, the color brightness near the tip of another type of short fiber is smaller than the color brightness of the long fiber. For example, by appropriately mixing and using these short fibers, the color brightness of the long fibers can be made greater than the color brightness near the tips of the group of mixed short fibers. It is.

Most preferably, the lightness of the color near the tips of all the short fibers used is smaller than the lightness of the color of the long fibers.

The lightness (L value) is determined by a color difference meter, and examples of the color difference meter include Hunter's direct-reading photoelectric color difference meter according to J I 5-Z-8722 or the digital color measurement color difference calculator AUD-3CH- Type 2 (manufactured by Suga Test Instruments) is available, and the brightness can be determined by the L value.

Such lightness (L value) is expressed as a numerical value from 0 to 100,
The larger the number of L values, the higher the brightness, that is, the brighter it is. Therefore, the L value of black is close to 0 (and the L value of white is close to 0).
The value will be close to 100. In the present invention, the L value of the long fiber and the L value of the portion near the tip of the short fiber are values measured according to JIS-Z-8722, as described above. That is, both values are values obtained by separately measuring each fiber after coloring.

In the measurement of brightness, long fibers can be measured by the method described above. However, since the color of short fibers is different between the part near the tip and the other part, the brightness of the short fiber is measured after cutting the part near the tip. Therefore, when a mixture of two or more long fibers is used as in the present invention, in order to determine the brightness of each color by cutting off the portion near the tip of each fiber, it is necessary to measure each color separately. In addition, in order to determine the brightness in a mixed state, the portion near the cut tip is mixed at a weight ratio that matches the mixing ratio, and then measured.

In the present invention, in order to enhance the three-dimensional effect, the final product is
As shown in FIG. 1, it is desirable that the napped layer structure has a multi-ridged structure. That is, FIG. 1 is a cross-sectional view taken in a direction perpendicular to the direction of the raised pile, and shows that a large number of raised fibers 3 are raised from the base fabric 2 to form the artificial fur fabric 1, which emphasizes the three-dimensional effect. It has a multi-ridged nape layer structure.

In other words, the structure shown in FIG. 1 forms a convex nap layer with one ridge width P by having a distribution in the nap length of the nap fibers 3. By making it lean, the three-dimensional effect is emphasized. This part of the napped fibers 3 forms a two-layer structure as shown in Figure 2.
It is composed of raised hair consisting of long fibers (G) for pricking and raised hair consisting of short fibers (A, Bg, B3...) for fluff. Figure 3 shows the nape consisting of long fibers (G) and short fibers (A, Bs).

This is a model representation of the piloerection consisting of B2...).

That is, the raised hair made of long fibers (G) in the present invention corresponds to the prickly hair of fur having a two-layer structure, and is usually longer and thicker than fluff.

In general, prickly hair is a standing fluff that covers fluff, forms the appearance of fur, and has the function of imparting the feel of fur, and is preferably strong, elastic, and with an appropriate fiber thickness. That is, the single fiber fineness is 5 to 60 deniers, more preferably 20 to 60 deniers.
Fibers having a denier of 50 denier and an average fiber length of 10 mm or more and 70 mm or less, more preferably 20 to 60 mm are used.

On the other hand, the piloe consisting of short fibers corresponds to the fluff of fur with a two-layer structure, and is shorter than the piloere, which protects the piloerection and elasticity of the bristle, and has a cold protection function. Fibers having a single fiber fineness of 0°1 to 5 denier, more preferably 1 to 3 denier, and an average fiber length of 50 mm or less to 5 mm or more, more preferably 10 to 4 Qmm are used. Here, the long fibers are preferably several mm or more, more preferably 5 mm or more longer than the short fibers.

Fibers for hair cutting and fibers for fluff include synthetic fibers such as polyester, polyamide, and polyacrylic; recycled fibers such as rayon, cotton wool, and cupro; semi-synthetic fibers such as acetate; and cotton, hemp, and wool. Natural fibers and mixed fibers thereof can be used.

In addition, in the artificial fur of the present invention, it is preferable that the raised hairs have sharpened tips, and by adopting such a structure, the texture, feel, appearance, etc. can be made even better. . In this case, the above effect can be achieved by sharpening at least the prickly nape, but if the fluffy nape is also sharpened, the texture and feel will be softer and smoother. becomes.

Therefore, among the above fibers, polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) are preferred in terms of ease of sharpening the tip.
It can be said that polyester-based synthetic fibers such as the following are desirable because they can be easily sharpened and have excellent elasticity.

In addition, when considering durability, processability, and ease of handling, it is preferable to select the fiber for fluff from the above synthetic fibers, but according to the findings of the present inventors, polyester-based synthetic fibers are used. This is the most preferable one since it causes less settling of the napped layer.

In the present invention, when using synthetic fibers, it is important to use fibers that have been heat-treated after spinning and drawing, straight fibers without crimping, or sharpened fibers to improve the straightness of the naps. It can be made into products with excellent appearance and soft feel, and is extremely suitable for use as pricking hair. The fluff has a crimp degree of 12 to 13% or less, and a number of Ken lines of 15 to 16.
It is desirable to have low crimp, on the order of inches or less.

In the present invention, it is preferable that the long fibers constituting the napped hair have a flattened cross section with a degree of flatness of 1.5 or more. It is possible to make the presence of prickly-like raised hairs good without significantly increasing or deteriorating the roughness and hardness of the hair or the usage ratio. The flattened cross section typically refers to the ellipse shown in Figure 5A or the flattened cross section shown in Figure 5B, and the flatness is the value expressed by the ratio of major axis to minor axis. In FIGS. 5A and 5B, the value represented by b/a is the flatness.

The napping formation method includes, for example, mixing or blending two dyed fibers in an appropriate weight ratio to create a woven fabric,
A method of flocking these two fibers into knitted fabrics, non-woven fabrics, etc., a method of knitting into a pile knitted fabric, a method of knitting with a sliver knitting machine, a method of weaving a double woven fabric with a double loom and then connecting the two woven fabrics. Examples include a method of obtaining a pile fabric by cutting the pile warp yarns with a knife, that is, a method described in JP-A-57-61739 or JP-A-57-167434.

The mixing ratio of long fibers and short fibers is long fiber/short fiber in weight ratio.
The ratio of short fibers is preferably 10 to 90/90 to 10, more preferably 35 to 65/65 to 35 of long fibers/short fibers.

The fur-like fabric thus obtained can be subjected to post-processing such as backing, lazing, brushing, etc., if necessary.

〔Effect of the invention〕

As described above, the present invention has two layers of napped hair made of long fibers and napped hair made of short fibers. At least two different colors are used, and furthermore, these different colors are substantially complementary colors, and moreover, a difference in brightness is created in the vicinity of the tips of the long fibers and the short fibers.

This not only allows the long fibers for embroidery and the short fibers for fluff to be separated by color, but also changes the color of each part when the fabric is tailored and worn, depending on the viewing direction and angle. It looks vivid and different as it moves, giving it an iridescent color that gives it a novel aesthetic and a sense of luxury. In addition, a more preferred embodiment of the present invention in which the two fibers have the above-mentioned lightness difference relationship achieves even greater depth of color and gloss, and is more aesthetically pleasing. Become.

The blending ratio of short fibers for pricking/short fibers for fluff is 40 in both cases.
/60% by weight.

During weaving, due to the pile yarn arrangement design during warping, the pile yarn (E) forms a raised center part with a width of 7 mm on the product, while on the left and right of it, (E) and (F)
The mixed raised part, (F) raised raised part, the mixed raised raised part of (F) and (G), and the raised raised part of (G) each have a width of 7 mm in this order, and one ridge is 63 mm wide, giving a gentle appearance. The aim was to create a multi-ridged structure as shown in Figure 2, which forms a dome-shaped layer of raised hair.

Furthermore, the material for the ground warp threads that form the ground texture is PET.
Weaving was carried out using long fibers, the main structure was a dark brown acidic material, and the portions forming the boundaries between the ridges were 5 mm wide and a dark brown acidic material was used.

After weaving, the back side of the greige fabric is coated with polyurethane resin, the fibers are opened, and the pile fabric obtained by handling the pile fabric has a gentle dome-like nap distribution with a ridge pitch of 6.3 cm, as shown in the schematic model in Figure 1. It had a multi-ridged structure in the width direction, and on the back side, a dark brown base texture part 5 with a width of 6 mm formed streaks on the dark brown main base texture part.

(Margins below this page) (5) As shown in Table 1, the artificial fur in this post is blue (A) and bluish green (Bl).
), or the other parts are (A), (Bl)
Both are pale reddish-purple in color.

The brightness of the portion near the tip of (A) is greater than the brightness of the filament fiber, but the brightness of (B,) is smaller. However, when the two fluffs were mixed together at a rate of 50%, it was possible to achieve a lightness close to that of fibers for pricking hair. Moreover, in (B1), the portion near the tip and the other portions have a substantially complementary color relationship.

This kind of artificial fur is rich in color and exhibits a so-called iridescent color, which appears to vary depending on the viewing angle and direction. However, since the brightness of the prickly hairs and the fluff are almost the same, some fluff can be seen between the prickly hairs, so the appearance quality cannot be said to be excellent.

That is, in each fluff, the color of the portion near the tip and the color of the other portion are substantially complementary colors. Furthermore, the portion near the tip and the other portions have a substantially complementary color relationship. Moreover, because the bristles are blue, the difference in brightness between the color of the bristles and the fluff is as much as 3.3.

As with Example 3, such artificial fur has excellent depth and luster in the color of the stinging hair, and furthermore, it exhibits a richer iridescent color. there were.

When this artificial fur is worn as clothing, as mentioned above, the color appears different depending on the viewing angle and direction of the clothing, or the movement of the wearer, and the amount of light reflected from various parts also differs.

40gzlThe area around the tip/other parts from both ends of the short cotton fibers dyed in this way up to an average of 6mm is (A) red/blue, (Bl) bluish green/pale red, ( B2) was stained yellow-red/pale blue-green. The brightness near the tip of each line was 24.2.22.4.26.5, respectively.

(3) The above ll11λ1 was manufactured using the same processing method as in Example 1. However, the fluff fibers (A, BI+Bz) are 20% by weight, respectively.
A mixture of 70% and 10% was used.

The brightness of the east line thus mixed was 23.2 as measured in accordance with Example 1 (4).

(4), LJ! L As described in Table 1, this artificial fur uses fluff consisting of three different colors, but there are seven sets of colors that are essentially complementary colors.

In such artificial fur, the iridescent tone was more emphasized than the color of Example 4.

Comparative example 1 (11 plates The east line dyed in Example 3 was used.

(2) Minami Hosen Fouza Bunke Negative Excluding the multiple bundles of paper in Example 1, the defibrated staples were dyed in a package dyeing machine using the same dyeing process as the fiber for pricking at 130°C for 60 min. Stained for minutes. However, the bath ratio was 1Nia, and the dye processing method was as follows.

(al Fiber for fluff (A) The same dyes as dye liquid ■ for (A) in Example 1, blue, orange, and lupine at 2.0%, 10%, and 0.10%, respectively.
, h, f, were used.

Mountain) Fiber for fluff (B,) The same dyes as in dye solution (B) for (Bl) in Example 1, 0.8% blue and yellow, were used at 0.8% and 1.0%, respectively.

Both ends and the middle part of the cotton dyed in this way were the same color, with (A) being dyed blue and (B1) being dyed bluish-green. The brightness of this east line is 20.1
(A), 24.6 (Bl).

(3) Fur Star Yanryu ■Production Manufactured using the same processing method as in Example 1. However, the mixing ratio of short fibers is 90% by weight for (A) and 10% by weight for (B,).
Weight%.

(4) Hill: The fluff of this artificial fur has the same color in the vicinity of its tip and in other parts. Moreover, since blue and blue-green are not substantially complementary colors, they do not exhibit an iridescent color. Since the lightness of the fluff was greater than the brightness of the prickly hairs, the fluff stood out between the prickles, resulting in poor appearance quality.

Comparative example 2 (11) Dan Y The collected cotton dyed in Example 4 was used.

(2) Kimo Hosenou ■ Bundle The same staples as in Comparative Example 1 were dyed under the same dyeing conditions.

However, the dye treatment is as follows.

(a) Fiber for fluff (A) The same dyes as in dye liquor I for (B,) of Example 3, orange and lupine were used at 1.35%, 3.15% o, w and f, respectively.

(b) Fiber for fluff (B,) The same dye liquor as for (B,) of Comparative Example 1 was used.

(C) Fiber for fluff (B2) The same dyes as in dye solution (B2) in Example 5, orange and red were used at 6%, 3% o, w, and f, respectively.

Both ends and the middle part of the cotton thus dyed were the same color, and were dyed red (A), blue-green (B1), and yellow-red (B2), respectively.

The brightness of the area near each tip is 24.2.24.6, respectively.
．． It was 28.2.

(3) Gyokuhide Monsakugo ■l-made by the same processing method as in Example 1. However, each cotton collection used was a mixture of 30%, 40%, and 30% by weight, respectively.

(4) Evaluation As with Comparative Example 1, each fluff of this artificial fur has the same color in the vicinity of the tip and in the other parts. In these fluffs, red and blue-green, and blue-green and yellow-red are substantially complementary colors.

Although such artificial fur exhibited an iridescent color, the degree of the color was inferior to that of the product of the present invention.
