Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a new artificial fur that has an iridescent color, has excellent color depth and gloss, and is highly aesthetically pleasing. .

[Problems with conventional technology]

Many attempts have been made to artificially obtain high-quality natural fur-like fabrics.

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, respectively.
Generally, the latter is set within a range of about 5 to 20 mm, and the former is set to be at least several mm longer than the latter, so that the two-layer structure is as clear 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 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. The relationship between the color of the stinging hair and fluff is as follows:
It is like the providence of the natural world, and is almost unchanging.

On the other hand, natural fur is made by using white mink fur or generally low-grade mink fur that has been bleached and dyed with black, etc., to achieve the same color as the ultra-high-quality mink mentioned above. There is also a product, but in this case, the color of the stinging hair and the fluff are the same color and the same concentration,
Generally, it is somewhat less beautiful and its commercial value is relatively low.

The relationship between the color of stinging hair and fluff in the field of natural fur is as described above. The result of intensive study on the relative relationship between the colors of prickly hair and downy hair, which can give new aesthetics and color appearances that have not been seen in conventional natural or artificial fur. , the present invention has been achieved.

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 an excellent sense of depth and luster, which is an extremely novel 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 a large number of long fibers and a nape consisting of short fibers, and the color of the part near the tip of the large number of long fibers is different from the color of the other part. The nap is composed of long fibers A, and other long fibers B having at least near the tips a color different from both the color near the tips of the long fibers A and the other parts. It features artificial fur.

[Explanation of configuration]

In the present invention, the different color in the long fiber A is a color that can be distinguished with the naked eye from the color in the vicinity of the tip of the long fiber A. Therefore, the different colors do not only refer to different hues such as a combination of red and green or a combination of blue and yellow, but also include the same hue but with differences in shading that can be discerned with the naked eye.

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) In the piece dyeing method, after the fabric is formed, it is immersed in a dye solution, dehydrated, and dried, and then a dye solution that becomes a different color is used to apply the tip of the nap of the fabric using the printing method. , drying, and coloring treatment method (2) Nine bundles of dyed 1 addition (a) Line up the fibers of a predetermined length, apply a dye solution that produces a different color to the center and both ends of the fibers, dry, A method of fixing the color and making a raised fabric using the thus dyed fibers (b) A fiber bundle of pre-dyed fibers is formed, and both ends are dyed in a different color from the central part of the fiber bundle. A method in which a dye solution is applied and a coloring treatment is performed, or a method in which a coloring treatment is performed while the bundle is immersed in this dye bath. A method of coloring the bundle while immersing it in a dye solution (3) As a yarn dyeing/piece dyeing method, after forming a fabric with pre-dyed fibers, using a dye solution that becomes a different color from the cough color, 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 long fibers used in the present invention are composed of fibers dyed as follows. In other words, there is a long fiber A in which the part near the tip and the rest 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 part, but the other part is the same color.It consists of a combination with long fiber B. thing.

or (2) A combination of long fibers B2 in which the color of the portion near the tip and the color of the other portions are both different from the color of A near the tip and the color of the other portion.

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

Or, ■ A long fiber B that is a different color from the above A, B, Bt.
3. B4 consists of a combination with...

etc.

When long fibers made of such a combination were evaluated with artificial fur using short fibers of the same color, the depth of color, sense of color, and aesthetics were superior 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 long 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, in each of the above-mentioned methods, except for method (2) (a), a dye solution is applied to the long fibers, or after dyeing, a dye solution that is substantially complementary to the long fibers is applied. 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 deeper color and gloss, any of the above-mentioned long fibers A, B, B, etc. It is preferable that the color brightness of the short fiber is smaller than the color brightness near the tip of the fiber, and it is preferable that the difference in brightness (ΔL value) is at least 0.5 or more, and more preferably, based on the findings of the present inventors. According to the above, it is best if the brightness difference (ΔL value) is 2.5 or more.

By creating a relative relationship between the brightness of both fibers,
Visually, the raised hair made of long fibers appears to cover up the raised hair made of short fibers, creating a high-quality, aesthetically pleasing product with an iridescent color, a stronger sense of color depth, and a glossy appearance. It is possible to obtain artificial fur that has a good feel and has a high commercial value.

Such artificial fur is obtained by making the lightness of the color of the short fibers smaller than the lightness of the part near the tip of the long fiber of at least one color among two or more types of long fibers of different colors. be. And, more preferably, long fibers A-B t , B z exhibiting various colors
It is preferable that the color near the tip of the short fibers is smaller than the brightness measured as a mixed fiber group in the mixed state forming the artificial fur, and at least the difference in brightness is is 0.5 or more, more preferably 2
．． It is preferable that the number is 5 or more.

In other words, even if the color brightness near the tips of one type of long fiber is smaller than the color brightness of the short fibers, the color brightness near the tips of other types of long fibers is greater than the color brightness of the short fibers. For example, by appropriately mixing and using these long fibers, the lightness of the color of the short fibers can be made smaller than the lightness of the color near the tips of the group of mixed long fibers. It is.

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

In addition, the lightness (L value) is determined by a color difference meter, and the color difference meter is a direct reading rechargeable color difference meter by Hunter according to J I 5-Z-8722 or a digital embellishment 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 brightness (L value) is expressed by a numerical value of θ ~ 100,
The larger the number of L values, the higher the lightness, that is, the brighter it is. Therefore, black has an L value close to 0, and white has an L value close to 0.
In the present invention, the L value near the tip of the long fiber and the L value of the short fiber are values measured according to JI 5-Z-8722, as described above. . That is, both values are values obtained by separately measuring each fiber after coloring.

The brightness of a portion near the tip of a long fiber is measured by cutting the portion. Therefore, when two or more types of long fibers are used as a mixture as in the present invention, it is necessary to cut off the portion near the tip of each and measure the brightness of each color separately. 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, it is desirable that the napped layer structure of the final product has a multi-ridged structure as shown in FIG. This is a cross-sectional view showing a large number of napped fibers 3 raised from a base fabric 2 to form an artificial fur fabric 1, which has a multi-ridged napped layer structure to emphasize the three-dimensional effect. It is.

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.
Long fibers for stinging hair (A, Bl, Bt'-...
) and a nap consisting of short fluff fibers (W). Figure 3 shows this long fiber (A,
Bt, Bz...) consisting of piloerection and short fibers (
This is a model representation of the piloerection consisting of W).

In other words, the raised hair consisting of long fibers in the present invention refers to 2
It corresponds to the prickly hairs of fur that has a layered structure, and is usually longer and thicker than fluff. In general, the hair is a standing hair that has the function of covering fluff, forming the appearance of fur, and giving the feel of fur. is 5 to 60 deniers, more preferably 20 to 50 deniers, and the average fiber length is 19 m.
m or more and 70 mm or less, more preferably 20 to 60 mm
fibers are used.

On the other hand, the piloe consisting of short fibers (W) corresponds to the fluff of fur with a two-layer structure, is shorter than the pilaf, and protects the piloerection and elasticity of the bristle, and has a cold protection function. Usually, the single fiber fineness is 0.1 to 5 deniers, more preferably 1 to 3 deniers, and the average fiber length is 50 mm or less, 5 m.
Fibers having a diameter of at least 100 mm, more preferably from 10 to 40 mm, are used. Here, the long fiber (A') is the short fiber (W
), it is preferable to use fibers that are several mm or longer, more preferably 5 mm or longer.

Examples of fibers for pricking and 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, cotton, linen, and wool fibers. Natural fibers and mixed fibers thereof can also be used.

In addition, in the artificial fur of the present invention, it is preferable that the tip of the raised hair is sharpened, and by adopting such a structure, the texture, feel, appearance, etc. can be improved by 7 layers. be able to. In this case, if we at least sharpen the brush strokes, the above effect can be achieved, but if we also sharpen the fluffy brush strokes, the air and feel will become even better. Flexible F
It becomes smooth. 4 Therefore, among the above-mentioned fibers, in terms of ease of sharpening the tip, polyester fibers such as polyethylene terephthalate (PET) and polystyrene phthalate (P,, B T ) are preferred. Fibers are desirable because they are easy to process and have excellent elasticity; In this case, it is preferable to select from the above synthetic fibers, but according to the findings of the present inventors, it is most preferable to use polyester-based synthetic fibers because they cause less stiffness in the napped fabric. In the present invention, when using synthetic fibers, it is necessary to use fibers that have been heat-treated after spinning and drawing, and straight fibers without crimping, or to sharpen them. It has excellent sexiness, beauty, softness, and firm feel, making it extremely suitable for pricking hair. It is desirable that the fluff has a low crimping degree of about 12 to 13% or less and a number of crimp lines of about 15 to 16 ridges/inch or less.

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

2 Processes The fur-like fabric obtained in this manner can be subjected to finishing processes such as banking, rebubbling, gagging, brushing, etc. as required. [Effects of the Invention] As described above, the present invention provides Erect hair consisting of fibers, and standing hair consisting of hair and short fibers? For long fibers that have two layers, at least 2' types of fibers with different colors in the vicinity of the tip and other parts are used, and furthermore, this different color is substantially a complementary color. In addition, there is a difference in brightness between 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 cut into corners, but also allows the color of each part to change depending on the viewing direction and angle, as well as the wearer's color when the fabric is tailored and worn. It looks vivid and different as it moves, giving it an iridescent color that gives it a novel aesthetic and a sense of luxury. Further, in a more preferred embodiment of the present invention in which the side fibers have the above-mentioned lightness difference relationship, further depth of color and glossiness are achieved, resulting in even higher aesthetics. .

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to Examples.

Example 1 (1) Sharpening power of filament fiber [polybutylene terephthalate stable (single yarn fineness 4

cm) were respectively immersed in a 40% caustic soda solution and treated at 105°C for 60 minutes. After treatment, decomposed products were removed by thorough washing with water. The obtained fibers have a good taper at both ends, and the fiber lengths are 29 mm, 27 mm, and 23 mm.
Met.

(2) Dyeing of fibers for stinging The above-mentioned sharpened bundle-shaped stable is oriented vertically,
Each piece was impregnated with dye solution I having the following treatment, and then turned sideways and the dye solution adhering to both ends was removed with water. The fiber bundle was immersed in a dye solution (1) prepared at a bath ratio of 1:5 with the same dye solution treatment as the dye solution (1), and placed in a high-pressure steamer for 130 minutes.
Color development treatment was performed at ℃ for 90 minutes.

After the color development treatment using 40 g/J of Blue FBL, the part was washed in a bundle in a well-known reduction washing bath by moving it up and down.

The long fibers for stinging hair dyed in this manner were dyed blue (A) and blue-green (B1) up to an average of 5 mm from both ends. Also, the middle part is (A),
(Bl) was also dyed pale reddish-purple.

To measure the brightness near the tip, we cut out the blue and blue-green parts of each nucleus. This cotton is measured separately using a digital color measurement color difference calculator model AUD-3CH-2 (manufactured by Suga Test Instruments).
The lightness was determined by putting 1 G into a cotton collection cell (diameter 35 mm, depth 5 mm). The brightness of the area near each tip measured in this way is 25.2 for (A) and 25.2 for (B,).
It was 0.5.

(3) Cotton ° (W) dark colored polyethylene telecrate stable (2dx20

After dyeing, the area was subjected to reduction cleaning, hot water, and water washing using a well-known method.

All of the cotton dyed in this way was dyed red. The brightness of this collected cotton was measured using the same method as in (2) and found to be 22.2.

(4) Manufacture of a fur-like pile fabric by blending short fibers for pricking (A, B+) and short fibers for fluff (W) to make pile yarn.

Prior to weaving, the following three types of pile yarns, E, F, and G, were made.

Short fibers for fluff 2dx16mm, the same color as (E) yarn fluff.

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 yarn, and the border between the ridges was a dark brown yarn with a width of (imm).

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.

(5) Evaluation As described in Table 1, the colors of the hair fibers near the tips of this artificial fur are different, blue (A) and blue (A).
, bluish-green (B,), or the other parts are (A)
, (Bl) are both pale reddish-purple. The brightness of the blue color in (A) is greater than that of the fluff fiber, but the brightness of the blue-green color in (B+) is smaller. However, when you mix blue and blue-green, you get something that approaches the lightness of fluff. Moreover, in (B,), the color of the portion near the tip and the color of the other portion are substantially complementary colors.

Such artificial fur is rich in color, and exhibits a so-called iridescent color that appears different depending on the viewing angle and direction. However, since the brightness of the prickly bristles was 0.3 greater than the lightness of the fluff, some fluff was visible between the prickly bristles, so the appearance quality could not be said to be excellent.

Example 2 (1) Wound 1" Cotton collection (A) and (Bl) dyed in Example 1 were used.

(2) Toyoko ■Senou The collected cotton dyed in Example 1 was used.

It is a zero-tier economy. The lightness of this mixed cotton was 24.7.

(4) Evaluation The colors of the prickles and fluff of this artificial fur are the same as in Example 1. However, by changing the ratio of hair fibers, the brightness was greater than that in Example 1.

In addition to the effects of Example 1, such artificial fur had improved color depth and luster because the prickly hairs appeared to be lifted from the fluff.

Example 3 (1) Fiber for pricking The collected cotton (A) and (Bl) dyed in Example 1 were used.

(2) Dyeing of fluff fiber (W) Dyeing was carried out using the same staples and under the same dyeing conditions as in Example 1. However, the dye treatment method is as follows.

(3) Hair II control 1 crawl It was manufactured using the same processing method as in Example 2.

(4) Evaluation The bristles of this artificial fur are the same as in Example 2.

However, because black was used for the fluff, the brightness of the two types of prickly hairs was greater than that of the fluff. Therefore, the difference in brightness between prickly hair and fluff is as much as 8.0.

In addition to the color of Example 2, in this artificial fur, the prickly hairs appeared to be completely lifted from the fluff, and as a result, the color depth and luster of the prickly hairs were further improved.

Example 4 (1) Dyeing of fiber for stinging hair Using the same stable as in Example 1, dyeing was carried out under the same dyeing conditions. However, the dye treatment method is as follows.

(2) Fiber for Fluff (W) The collected cotton used in Example 3 was used. However, stinging fibers (
The mixing ratio of A) and (B1) is 50% by weight each.

The lightness of this mixed cotton was 23.6.

(3) Evaluation As shown in Table 1, this artificial fur uses hairs of two different colors, and there are four sets of colors that are essentially complementary colors. That is, in each of the bristles, 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 black is used for the fluff, the difference in brightness between the color of the prickly hair and the color of the fluff is as much as 6.9.

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. It had a variety of colors that could not be seen in conventional products, giving it an excellent sense of luxury and aesthetics, giving it the appearance of an iridescent color.

(4) As shown in Table 1, the artificial fur graded 3 uses prickly hairs of three different colors, but there are only seven complementary colors.
There are also groups.

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

Comparative Example 1 (1) The loose hair-like staples sharpened in Example 1 were dyed in the same dyeing process as in Example 1 (3) using a high-pressure paddle dyeing machine for 120 min. Staining was carried out for 60 minutes at °C. However, the bath ratio is 1

(2) Fluff fiber (W) The east line of Example 1 was used.

(3) Manufacture of fur-like fabric It was manufactured using the same processing method as in Example 1.

(4) Evaluation The prickly hairs of this artificial fur have the same color in the vicinity of their tips 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.
