Description

Sheet-like material that changes color when stretched

The present invention relates to a sheet-like material that changes color by stretching.

For example, it is an everyday experience that the color seen before wearing and the color seen when worn are different. This is thought to be because the original color appears to have become lighter as the fabric is pulled by the wearer's body shape and the area is expanded.

The inventor of the present case has a novel effect of color change if a sheet-like material that changes color according to the body shape when worn or changes color according to the shape when applied to interior goods is obtained. We have been developing with the idea that the materials shown can be obtained. This is because if a garment using such a material is worn, the same garment may appear different colors depending on the wearer having a different body shape or by changing the body shape of the wearer.

Therefore, when prior art was investigated, Japanese Utility Model Publication No. 5-85818 was found. It has the purpose of changing the color and pattern appearance of clothing and enhancing the added value of the appearance, and is composed of a multi-layer structure consisting of an outer surface with openings and a multi-colored lining. By changing the degree of expression from the opening, the color and pattern are changed. However, in a multilayer structure in which the outer material and the lining material are combined, the distance between the fabrics becomes non-uniform, and the problem is how to shift the material, and it cannot be said that manufacturing is easy.

In JP 2009-46794, a front side fabric composed of a mask and an opening window and a back side fabric separated into two colors are fixed by loosening with a connecting means such as a thread, so that the front side fabric and the back side fabric are relative to each other. The invention proposes that the color and the pattern visible from the table change. However, this invention also needs to be provided with an opening or a transparent window on the front side fabric, and it can be said that the invention is of the same idea as the utility model in the sense that the lining is expressed from the opening. In addition, in the structure in which the front side fabric and the back side fabric are fixed using slack using a thread or the like, problems such as the fixing force varies depending on the location or the thread breaks may occur.

The present invention has been made in view of the above points, and an object thereof is to provide a sheet-like material whose surface color changes depending on the body shape of the wearer and the shape of the object to be applied. Moreover, the other subject of this invention is providing the sheet-like raw material which has the novel effect which changes a color according to the unevenness | corrugation of what is applied.

In order to solve the above-described problems, the present invention provides a sheet-like material whose color changes due to stretching in the first element that appears mainly on the surface when no stretching force is applied, and in the same manner when the stretching force is not applied. The second element, which is covered with one element and hardly appears on the surface, is integrally combined. The first element and the second element are partially or entirely different in color and are subjected to an extension force. In the comparison between the case where no tension is applied and the case where an extension force is applied, a means is adopted in which the colors appearing on the surface appear differently.

In the sheet-like material of the present invention, when an extension force is applied, the proportion of the second element that is covered with the first element and hardly appears on the surface increases. The first element expands due to the extension force to create a gap, or the gap expands and the second element appears, or the ratio of the gap increases, resulting in different colors appearing on the surface.

The color of the first element and the second element is different in part or all. When only some of the colors are different, the different color portions appear on the surface as if they were patterns or marks. Further, when all the colors are different, the color appearing on the surface changes as a whole, but the change in the color changes according to the degree of expansion.

A configuration in which the first element and the second element both have a woven structure in which yarns are knitted and the surface of the first element is printed with ink of a color different from the fabric color is preferable in the present invention. The first element and the second element are combined together by a woven structure, and the difference between the first element and the second element is realized by a simple printing means called printing.

Furthermore, both the first element and the second element have a stretchable woven structure in which yarns are knitted so that the color distribution appearing on the surface differs depending on the difference between the degree of expansion and contraction. This is also a preferable configuration. That is, in the above configuration, only the color is changed by the expansion, but even if the color is changed after the expansion, the original color is changed by the contraction by the configuration as described above.

Therefore, the sheet-like material of the present invention has a more useful form by forming a stretchable fabric structure. For example, rib knitting (rubber knitting), knitting knitting, and the like are performed as a knitting method of a stretchable woven structure. The sheet-like material of the present invention can be produced by any known knitting method, but elastic rib knitting is suitable.

Further, the present invention is extendable, and is in a state where the first element mainly appears on the surface when no stretching force is applied, and is also covered with the first element and hardly appears on the surface when no stretching force is applied. The first element and the second element have different colors in part or all of the first element and the second element, and a comparison is made between when no extension force is applied and when an extension force is applied , The first element and the second element have a stretchable fabric structure in which yarns are knitted together, and the degree of extension. And a garment configured such that the distribution of colors appearing on the surface differs depending on the difference between the degree of shrinkage and the degree of shrinkage. Such clothing can show a difference in body shape as a change in color tone, and is useful for management of the body shape.

Since the present invention is configured and operates as described above, the color that appears on the surface when an extension force is applied appears differently, depending on the body shape of the person wearing and the shape of the object to be applied. Thus, the sheet-like material that can be seen on the surface can be provided. Moreover, according to this invention, the sheet-like raw material which has the novel effect which changes a color according to the unevenness | corrugation of what is applied can be provided.

An example of the sheet-like raw material which changes a color by extension | expansion based on this invention is shown, A is an end view which shows a textile structure, B is a top view. Similarly, the change of the color of the sheet-like material is schematically shown. A is an end view, and B is a plan view. It is explanatory drawing which shows the state before and behind which the color which appears on the surface differs in the sheet-like material similarly. Similarly, the usage example of the clothing using the sheet-like material of the present invention is shown, and A is an explanatory view showing a wearing state of a slim person and B is a wearing state of an obese person.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of a sheet-like material whose color is changed by stretching according to the present invention. 11 is a first element that can be stretched and appears mainly on the surface when no stretching force is applied, and 12 is similarly stretched. The second element is shown in a state that is possible and is not covered with the first element when it is not stretched.

In this embodiment, the first element 11 and the second element 12 together constitute a fabric having a stretchable fabric structure in which yarns are knitted. The woven structure is desirably a structure that can expand and contract both in the knitting direction and in a direction intersecting the knitting direction. However, particularly in the case of a fabric applied to clothing, it is desirable to have a structure that is more easily expanded and contracted in a direction in which it is expanded and contracted relatively frequently. Such a stretchable structure can be knitted by the above-described stretchable rib knitting, for example.

The material of the yarn used for weaving varies depending on the product formed by the sheet-like material. In the case of clothing, such as clothing for clothing similar to underwear, yarn made of nylon is suitable from the viewpoint of stretchability, stretchability, and the like. However, the yarn suitable for the sheet-like material of the present invention is not limited to the above, and various yarns such as nylon, cotton, and polyester can be used.

The first element 11 and the second element 12 are integrally combined as a result of being knitted by rib knitting. That is, the structure is different from the structure described in Patent Document 2 in which the front side fabric and the back side fabric are fixed by providing slack with a connecting means such as a thread. The first element 11 constituting the woven fabric structure appears mainly on the surface of the fabric when no tensile force is applied, and the second element 12 is likewise covered by the first element when no tensile force is applied. It is difficult to appear on the surface of the fabric.

FIG. 1 and FIG. 2 illustrate this state. FIG. 2 further shows a state in which the print surface 13 is formed on the surface of the first element 11 with ink of a color different from the fabric color. In FIG. 2, the printing of the first element 11 can be performed by a known printer using an arbitrary colored ink. The color of the second element 12 compared with this is the color of the fabric, that is, the color of the yarn used for knitting.

FIG. 3 shows the effect of expansion and contraction in the sheet-like material of the present invention having such a configuration. 3A and 3B show the same state as in FIGS. 2A and 2B, and the coloring of the print surface 13 of the first element 11 that mainly appears on the surface is conspicuous, and the color of the second element 12 is not conspicuous. As a result, the color of the entire sheet-like material becomes a color tone that is predominant from the color of the print surface 13 of the first element 11 (FIG. 3C).

When an extension force is applied to the sheet-like material, the interval between the first elements 11 increases, and the proportion of the second elements 12 that have been difficult to appear on the surface increases. This is an enlarged view of FIGS. 3A 'and B'. The proportion of the second element 12 changes in proportion to the magnitude of the extension force and is therefore continuous. Reference numeral 10 indicates a material surface in which coloring of the first element 11 appearing mainly on the surface is conspicuous, and 10 ′ indicates a material surface in a state in which the proportion occupied by the second element 12 is increased.

When the sheet-like material of the present invention configured as described above is used for clothes and worn by different body shapes, the second element 12 is strengthened in the developed part, and the first element 11 remains strong in the tightened part. Thus, the characteristics of the body shape are expressed by the color tone. In addition, in the case of the same person, even if the same clothes are worn, the color appears to change between obesity and slimming.

Such an effect is also useful as an underwear that informs the wearer of changes in body shape. An example of the underwear 14 to which the present invention is applied is shown in FIG. FIG. 4A shows a state worn when slimming, the color tone of the first element 11 is prioritized, and FIG. 4B shows an increase in priority of the color tone of the second element 12 when worn when obese. The above is an explanation of the body shape change by the same person, but the same applies to a case where a slim person and an obese person wear underwear 14 of the same size.

When using the sheet-like material of the present invention, the color of the second element 12 can be strengthened by stretching, or only the color of the first element 11 can appear on the surface by contraction. By applying such actions and effects, a novel and attractive dress can be made. Other than the above, for example, it is possible to make interior materials by forming a bag whose color tone changes depending on the amount of stored items, or a pattern whose color tone is changed by changing the degree of expansion and contraction in a plane, and has wide utility value. is there.

In general, it can be used as a material that helps self-management of rapidly changing pathological conditions such as edema and swelling and medical treatment by a doctor. For example, there is also an objective grasp of the degree of pressure when the bandage is wound, or use as a cloth or gauze for easily determining a sense of distance, and examples are as follows.
1. Application to maternity wear, etc. for pregnant women (you can feel the joy of growth).
2. Simplification and speed-up of symptom management with tights and socks for lower leg edema in patients with kidney disease etc.
3. Simplify and speed up symptom management of patients with liver disease, etc. by using ascites abdominal wrap or clothes (when it gets thicker, it is obvious).
4. Quantitative grasp of the degree of compression with a bandage, such as a patient who has received a wound (approximate compression can be controlled by color).
5. Tights for prevention of deep vein thrombosis patients (approx. Compression can be controlled by color).
6). Application to masks for pediatric diseases, etc. (It becomes possible to notice wearing properly so as to cover the whole.)
