Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an elegant artificial skin having an iridescent color.

[Problems with conventional technology]

In recent years, many attempts have been made to artificially obtain high-quality natural fur-like fabrics.

Fur-like fabrics, whether natural or artificial, have a nape structure with a unique three-dimensionality due to a large number of densely grown napes of a certain length.

When the fabric is made into clothing such as coats and jackets and is worn, the dense naps and the three-dimensionality caused by the naps are caused by the wearer's work and even the wind blowing. It is possible to produce subtle and vivid changes in color shading and gloss in appearance, as well as light movements and changes (swaying, fluttering) of a large number of piloerections and piloerection layers. This clothing product brings an elegant beauty and sense of value that is rich in luxury and aesthetics.

The luxury, rarity, and elegance of high-quality natural fur are due in part to the fact that the many beautiful pils and pils layers can move and change naturally and lightly, resulting in a subtle overall appearance. It is recognized that this is caused by changes in the shading of the upper color and changes in gloss.

In this way, whether natural or artificial, fur or fur-like fabrics can be said to have a raised structure with a unique three-dimensionality.On the other hand, when it comes to color, natural fur In particular, mink fur, which is hailed as a luxury item, comes in a wide variety of colors and varieties, including black, dark brown, light brown, and white-gray.These natural furs are not limited to mink. , In general, what is the color of the piloerection that forms the outer layer of the piloerection layer? Farming, on the other hand, the color of the raised hair on the inner layer, which inevitably becomes visible as the wearer works as described in section 2 or when the wind blows, is the same as above. It is the same color as the upright hair that makes up the outer layer, but is lighter or brighter than that color. However, such color difference relationships result in subtle changes in color shading and gloss in the overall appearance, as described in Section 2.

On the other hand, natural fur, which is generally low-grade natural fur that has been treated with white or bleached fur, is dyed in natural-like colors such as black, or bright colors that are not found in natural products. Fur is also present, but in this case, both the outer layer and the inner layer of the piloerection layer are of the same color and density, and -i-wise, they have the same elegance as mentioned above. It is inferior and has low commercial value.

In the case of conventional artificial products, the color of the napped fibers is only an imitation or a substitute for natural products, even if some effort has been made to make it look even slightly better (such as by using a special dyeing method for the napped fibers). In the end, the aim was to make it the same as natural products, and it must be said that the color reproduction of natural products and the same level of single color range as natural dyed products. It was a level of technology that could not be achieved, and it was also the immediate technical goal.

[Purpose of the invention]

Under the above-mentioned conventional technology, the present inventors have developed artificial fur that has reached a certain high level in terms of the piloerection layer structure, the density of the pilaf, and the condition of growth, compared to conventional natural or artificial fur. As a result of intensive research aimed at providing artificial fur with novel aesthetics and elegant color appearance, we have arrived at the artificial fur of the present invention, which has never been seen before. Out.

In particular, since the fabric structure is intended to have a fur-like appearance, the fabric structure has a remarkable three-dimensionality, so by making the color of the napped hair unique, the aesthetics of the product, the overall appearance, and the sense of luxury that can be obtained. It has a surprisingly large effect on elegance and rarity.

From this perspective, the purpose of the present invention is to provide a completely new artificial fur that makes it possible to discover a new sense of value that is extremely aesthetically rich and different from the beauty of high-quality natural fur. When this artificial fur or this artificial fur is made into clothing and worn, the color of the raised hair on each part of the clothing will vary vividly depending on the viewing direction and angle, and as the wearer moves. The aim is to provide artificial fur that is new and elegant and has an iridescent color that has not been seen before, and is full of rarity and luxury.

[Structure of the invention]

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

That is, the artificial fur is made up of a large number of napped fibers, and the color of the portion near the tip of the fibers constituting the napped fibers,
It is characterized in that the colors in the other parts of the fiber have a substantially complementary color relationship.

[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 in a opposing relationship to this color in the ``Complementary Color Relationship Indicating Complementary Color Relationship (JIS Z-8102)'' shown in Figure 4. Of course, this also includes the colors on both sides of the color that is in opposition to this color.For example, if a specific color is "yellow", this "yellow", "blue-purple" that is opposite to this "yellow", and both of them are also included. Also includes the neighboring colors "blue" and "purple".

When colors that are essentially complementary colors are applied to the areas near the tips of the fibers that make up the nap and the other parts, the artificial fur made of the fibers that make up the nap will have different colors depending on the viewing direction and angle. It becomes possible to exhibit an iridescent color effect.

Methods for imparting colors that are substantially complementary colors to the portion near the tip of the fibers constituting the nap and other portions include a piece-dying method, a yarn-dying method, and a yarn-dying/piece-dying method.

(1) As for post-dyeability, after the fabric is formed, it is immersed in a dye solution, dehydrated, and dried, and the leading edge of the fabric is printed using a dye solution that has a substantially complementary color relationship. Method of coating, drying, and coloring treatment (2) The yarn dyeing method includes (a) aligning fibers of a predetermined length and applying a dye solution with substantially complementary colors to the center and both ends of the fibers; Drying, color fixation, and method of making a raised fabric using the dyed fibers (b) Forming a fiber bundle of pre-dyed fibers, and forming a fiber bundle at both ends that is substantially the same as the color of the central part of the fiber bundle. A method of applying a dye solution that has a complementary color relationship and performing a color development process, or a method of performing a color development process while immersed in this dye bath (c) A dye solution is applied to an undyed fiber bundle, and then this color is applied. A method of developing color while immersed in a dye solution that has a substantially complementary color relationship +31 9eD There is a method in which the leading end of the fabric is coated using a printing method, dried, and colored.

In the present invention, in order to enhance the three-dimensional effect, it is desirable that the final product has a three-dimensional layered structure with a multi-ridged structure, as shown in FIG. In other words, 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, emphasizing 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. At this time P
The width is preferably within the range of 3 to 10 cm. FIG. 2 shows a model of this napped fiber 3, and the napped fiber 3 is dyed so that the tip portion a and the other portions are substantially complementary colors.

In the present invention, the fibers that form naps are fibers that have the function of forming the appearance of fur and giving the feel of fur, and are preferably elastic and have appropriate fiber thickness and length. .

That is, the single fiber fineness is 0.1 to 60 denier, more preferably 1 to 50 denier, and the fiber length is 5 to 60 mm.
More preferably, fibers having a diameter of 10 to 40 mm may be used.

Examples of fibers that make up the nap include polyester,
Synthetic fibers such as polyamide and polyacrylic, recycled fibers such as rayon, cotton wool, and cupro, semi-synthetic fibers such as acetate, natural fibers such as cotton, linen, and wool, and mixed fibers of these are listed as possible. It will be done. Among such fibers, polyester fibers are preferred because they have excellent elasticity.

In addition, in the present invention, when using fibers made of synthetic fibers, it is preferable to use fibers that have been heat-treated after spinning and drawing, straight fibers without crimping, or to be sharpened. It can be made into a fiber with excellent properties, beauty, and softness, making it extremely suitable as a fiber for napping.

The napping formation method includes, for example, a method in which fibers of a predetermined length are placed on a fabric body such as a woven fabric, knitted fabric, or nonwoven fabric and flocked by needle punching, a method in which the fibers are knitted into a pile knitted fabric, a method in which the fibers are knitted using a sliver knitting machine, A method of obtaining a pile fabric by cutting the pile warp connecting two fabrics with a knife after weaving into a double fabric using a double 8ti machine, that is, JP-A No. 57-61739 or JP-A No. Showa 5
Examples include the method described in Publication No. 7-167434 and the like.

The fur-like structure obtained in this way can be subjected to post-processing such as backing, lazing, brushing, etc., if necessary.

〔Effect of the invention〕

In the present invention, as shown in L, the color of the tip of the fiber constituting the nap and the color of the other parts are substantially complementary colors, so that the part near the tip of the nap, Because the other parts can be identified individually, not only do they appear vivid and colorful as the wearer moves and the pilasters and piloes move, but even a single-layer pilaster structure can have a deep multi-layered pilaster. It looks like a superstructure, and when the fabric is tailored and worn, the color of each part looks different depending on the direction and angle of viewing.It has an iridescent color and a luxurious feel. This is the result.
