Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to artificial fur with an emphasis on luxury.

[Problems with conventional technology]

In general, natural fur, especially mink, which is highly regarded as a luxury item, is typically black, such as black grama mink, dark mink, and brown, such as dark brown mahogany mink, light brown Lunarain mink, etc. There are high-quality varieties such as pastel mink and white-gray varieties such as sapphire mink, and there are a wide variety of other varieties, but in all of these natural furs, the color composition of the prickly hair and fluff is the same. The prickly hair is dark in color, and the fluff is lighter in color. This relationship between the light and dark colors of stinging hair and downy hair is like a law of nature in animals, and is almost unchangeable.

On the other hand, many artificial furs have been proposed that aim to resemble natural fur, such as mink fur. A typical example is a raised fabric that has a two-layer structure of prickly wool and fluff. In general, when aiming for a natural mink look in such artificial fur, the length of the raised hair is 15 to 3 Qmm for the former and 5 to 2 Qmm for the latter.
Usually, the length is within a range of about 0 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. Furthermore, in order to resemble natural mink, this napped fabric had a dark colored prickly hair and a lighter colored fluff.

However, in the field of artificial fur, even though the aim is to create a natural fur look, the conventional napkin technology for artificial fur does not work.
Inevitably, the prickly hair and fluff's shape, piloerection properties,
It can be said that it is difficult to make all the density and condition of the standing hair exactly the same as that of natural fur, and even if only the color tone of these hairs and fluff is made similar, the appearance will be similar to that of natural fur. The fluff may appear to be floating between the hairs, and there may be a lack of presence of prickly hairs, or there may be a lack of depth of color, and for these reasons, there may be a lack of a piloereous layer in appearance. In the end, it was difficult to make the mink look as beautiful or luxurious as, or even better than, the high-quality mink variety.

In addition, it is difficult in production to make the prickly hair and fluff exactly the same as natural fur in all aspects such as the shape of the raised hair, the quality of the raised hair, the density of the raised hair, and the growth condition.

[Purpose of the invention]

The relationship between the color of prickly hair and fluff in the field of natural fur is as described above, but the present inventors have investigated the relative relationship between the colors of prickly hair and fluff that can make the artificial fur look most beautiful in the field of artificial fur. As a result of intensive study, the present invention was arrived at. In particular, since fur is a material that has a remarkable three-dimensionality due to its structure, the delicate relationship between the colors of the embroidered hair and fluff greatly affects the overall appearance, beauty, and sense of luxury of the product. It depends on the left and right.

In view of the above-mentioned points, an object of the present invention is to provide artificial fur with the appearance of raised hairs made of long fibers, excellent overall color depth and clarity, and gloss. To provide artificial fur with a sense of beauty and luxury comparable to or superior to natural fur.

[Structure of the invention]

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

That is, it is an artificial fur having a two-layered nap layer structure of a nap consisting of long fibers and a nap consisting of short fibers, wherein the short fibers contain at least one color having a substantially complementary color relationship.
It is characterized in that the piloerection is structured so as to include a set of tufts.

[Explanation of configuration]

In the present invention, the substantially complementary color relationship refers to the relationship between a certain specified color and a color that is opposed to this color in the color circle J (JIS-Z-8102) showing the complementary color relationship shown in FIG. Of course, this includes the colors on both sides of the color that is in the opposing relationship with this color. For example, if the specific color is "yellow", it includes "yellow", "blue-purple" opposite to "yellow", and "blue" and "purple" on both sides thereof.

When one or more sets of such substantially complementary colors are applied to short fibers, the artificial fur, which has raised hairs made of long fibers and raised hairs made of short fibers, takes on a different color depending on the direction from which it is viewed. You will be able to exert an iridescent effect.

In order to obtain artificial fur that has a deeper color and a luxurious feel, it is preferable that the difference in color brightness (ΔL value) between long fibers and short fibers is 0.5 or more, and that the short fibers The lightness (L value) is preferably smaller than the lightness (L value) of the long fibers, and more preferably, according to the findings of the present inventors, the lightness difference (ΔL value) is 2.5
Anything above that is best.

By creating a relative relationship between the brightness of both fibers,
Visually, the raised hair made of long fibers appears to cover the raised hair made of short fibers, and in addition to the iridescent color, the artificial fur has a stronger color depth and luster. It is.

The lightness (L value) is determined by a color difference meter, and as a color difference meter, Hunter's direct-reading photoelectric color difference meter according to JIS-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.

The lightness (L value) is expressed by a numerical value of 0 to 1 (10), and the larger the L value, the higher the lightness, that is, the brighter it is. Therefore, the L value of black is close to O, and the L value of white is close to 1 (10). In the present invention, the L value of long fibers and the L value of short fibers are values measured according to JIS-Z-8722, as described above. That is, both values are values measured separately for each fiber after coloring, and this may be a value measured in the state of raw cotton before forming artificial fur, or After the artificial fur is formed, the value may be determined by dividing the raised hair into those originally consisting of long fibers and those originally consisting of short fibers.

In the present invention, in order to enhance the three-dimensional effect, it is desirable that the final product has a multi-ridged structure as a raised layer structure, as shown in FIG. 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 l.
The three-dimensional effect should be emphasized (it has a multi-ridged nap layer structure. In other words, the structure shown in Fig. 1 has a distribution in the nap length of the nap fibers 3, so that the width P of one ridge can be A convex nape layer is formed, and by creating a difference in the length of the nape, the three-dimensional effect is emphasized.

The width P is preferably within the range of 3 to 10 cm.

The napped fibers 3 form a two-layer structure as shown in Fig. 2, with napped fibers consisting of long fibers (A) and napped fibers (B) consisting of short fibers.
) consists of piloerection. FIG. 3 shows a model of the napped hair made of long fibers (A) and the napped hair made of short fibers (B).

The raised hair made of long fibers (A) 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, stinging hair is a standing pile that has the function of covering fluff, forming the appearance of fur, and giving it the feel of fur.
It is preferable to have strong 1, elasticity, and appropriate fiber thickness.

That is, the fibers used have a single fiber fineness of 5 to 60 deniers, more preferably 20 to 50 deniers, and an average fiber length of 10 mm to 70 mm, more preferably 20 to 60 mm.

On the other hand, the piloe consisting of short fibers (B) 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 5 Qmm or less, 5 m.
Fibers having a diameter of at least 100 mm, more preferably from 10 to 40 mm, are used. Here, long fibers (A) are short fibers (B)
It is preferable to use fibers that are several mm or longer, more preferably 5 mm or longer.

In addition, in the present invention, fur fibers (A
) and (B) can be obtained by cutting pre-dyed fibers into predetermined lengths, or by dyeing fibers cut into predetermined lengths.

In addition, the dyeing of long fibers (A) and short fibers (B) is as follows:
This is done using a normal dyeing method so that the color relationships described above are achieved.

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. Examples of usable materials include natural fibers and mixed fibers.

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 made even better. In this case, at least the above effects can be achieved by sharpening at least the prickly-like naps, but if the fluff-like naps are also sharpened, the texture and feel will be softer and smoother. .

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 fluff fiber from the synthetic fibers mentioned above, but according to the findings of the present inventors, it is preferable to use polyester synthetic fiber. However, 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 hair with excellent appearance, soft feel, and is extremely suitable for pricking hair. The fluff is
It is desirable to have a low crimp of about 12 to 13% or less and a crimp number of about 15 to 16 ridges/inch 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 rate. The flat cross section is typically shown in Figure 4A.
The oblateness is the value expressed by the major axis/minor axis ratio, and in Figures 4 A and B, it is expressed as b / a, respectively. The value shown is the flatness.

The napping formation method includes, for example, a method in which dyed side fibers are mixed or blended at an appropriate weight ratio, and the side fibers are flocked into a woven fabric, knitted fabric, nonwoven fabric, etc., a method in which the side fibers are knitted into pile fabric, and a sliver knitting machine. A method of knitting a double fabric using a double loom, a method of obtaining a pile fabric by cutting the pile warp connecting the two fabrics with a knife after weaving it into a double fabric using a double loom, etc. Examples include methods described in Japanese Patent Publication No. 57-167434 and the like.

The mixing ratio of long fibers (A) and short fibers (B) is 10 to 90/90 long fibers (A)/short fibers (B) in terms of weight ratio.
~10, more preferably long fibers (A)/short fibers (
The ratio of B) is preferably 35-65/65-35.

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

〔Effect of the invention〕

As described above, the artificial fur of the present invention has two layers of raised fur, one consisting of long fibers and the other consisting of short fibers, and the colors of the short fibers are substantially complementary colors,
Preferably, the lightness (L value) of the short fibers is smaller than the lightness (L value) of the long fibers, so the long fibers for pricking hair stand out, and the depth of the color, sharpness, and luster are emphasized. It is possible to obtain artificial fur that has an excellent appearance and has an iridescent appearance due to the short fibers, which emphasizes the appearance of high-quality windows.

(4) Production of fur-like fabrics Short fibers for pricking (A) and short fibers for fluff (B1゜B2.)
A fur-like pile fabric was created by blending these together to create pile yarn. Prior to weaving, the pile yarn is 3 types E, F, and G shown below.
I made different kinds of things.

■Pile yarn (E): Short fiber for embroidery 40dX29mm, color blue.

Short fiber for fluff 2dX20mm, mixing ratio: Bl (red) 50% by weight, Bz (green) 50% by weight.

■Pile thread (F): Short fiber for pricking hair 40dX27mm, color is the same as (E) thread piling thread.

■Pile thread (G): Short fiber for pricking hair 40dX23mm, color is the same as (E) thread piling thread.

Short fibers for fluff 2dX16mm, the mixing ratio is the same as above (■).

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-layered structure with dome-shaped raised hairs forming a layered portion, as shown in FIG.

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 boundary between the ridges was a 6 mm wide dark brown yarn.

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 extending in the width direction, and on the back side, dark brown ground texture portions 5 with a width of 6 mm formed streaks on the dark brown main texture portion.

(Leaving space below next summer) (5) Myo'' This artificial fur is made of red fluff B, as shown in Table 1.
and green fluff B2 have a substantially complementary color relationship. Artificial fur made from such fluff had an iridescent color depending on the direction and angle of viewing. However, since the difference in brightness between the prickly hairs and the fluff is as small as 0.8, the fluff appears to be slightly lifted from between the blue prickly hairs.

Example 2 (1) Fiber for stinging hair (A) The same cotton collection as in Example 1 was used.

Its concentration is high. Further, as shown in Table 1, the brightness is 3.4 smaller than that of stinging hair. This type of artificial fur has an iridescent appearance, and
The blue prickly hairs looked like they were standing out from the fluff, and the color had an excellent sense of depth and luster.

When this artificial fur was worn as clothing, the blue color of the stinging fur was emphasized as described above.
The colors appear different depending on the viewing angle and direction of the clothing, or the movement of the wearer, and the amount of light rays reflected in various parts also differs, making it look like an iridescent color, which is completely different from conventional clothing. It was an artificial fur with an unparalleled sense of luxury.
