Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a non-waterproof bordered garment having heat-sensitive reversible discoloration.

(Prior Art and Problems) Various thermosensitive and reversible color-changing ink compositions that change color depending on temperature have been known and have been put to practical use in the fields of towels, toys, and the like.

Attempts have been made to apply this thermochromism phenomenon to textile products such as clothing, but even when a thermosensitive reversible color-changing ink composition is applied or printed on fabric, the light fastness is low and it is not practical. The inventors of the present invention have developed a heat-sensitive reversible color-changing sheet that has improved the above-mentioned problems.
Already proposed as 240587.

On the other hand, materials with heat-sensitive reversible discoloration have never been used as materials for trimming clothing.

(Means for Solving the Problems) The purpose of the present invention is to solve the above-mentioned problems and to provide a thermosensitive reversibly color-changing fringe garment that can stably exhibit thermochromism over a long period of time.

The heat-sensitive, reversibly color-changing, non-waterproof fringe garment of the present invention has the following configuration. That is, a fiber base layer (A layer), a synthetic resin layer (B layer) containing thermosensitive reversible color-changing ink encapsulated in microcapsules, and a synthetic resin layer (C layer) containing an ultraviolet absorber and/or an antioxidant. layer) and (A
A heat-sensitive device characterized in that a coated fabric, which is a laminated structure in which the following layers are laminated in the order of layer) / (layer C) / (layer B) / (layer C), is used for at least a part of the border decoration. It is a non-waterproof hem garment that changes color reversibly.

In the present invention, non-waterproof fringe clothing refers to ordinary men's wear, women's wear, children's wear, and casual wear, etc., including ski wear, windbreakers, raincoats, etc. that have been actively waterproofed. Waterproof clothing such as waterproof jackets is not included.

The fiber base material used in the present invention may be any sheet-like material containing fiber as an essential component.
For example, synthetic fibers such as polyamide and polyester,
Regenerated fibers such as rayon and acetate, cotton, wool,
Examples include woven fabrics, knitted fabrics, non-woven fabrics, etc. made of natural fibers such as silk. These base materials can also be used after being dyed or treated with water repellent treatment.

As the heat-sensitive reversible color-changing ink, any substance or composition that changes color reversibly depending on temperature can be used. For example, Japanese Patent Publication No. 51-35414,
Those described in Japanese Patent Publication No. 51-44708 and Japanese Patent Publication No. 57-76072 are used. In order to effectively exhibit the thermochromism phenomenon near room temperature, it is particularly preferable to use a material that changes color at -20 to 50°C. In the present invention, in order to improve light resistance to a level that poses no practical problems, it is essential to disperse these heat-sensitive reversible color-changing inks in a synthetic resin while encapsulating them in microcapsules. Furthermore, by encapsulating heat-sensitive reversible color-changing ink in microcapsules, it has become possible to develop multiple colors independently.

Specific examples of synthetic resins used in the present invention include polyurethane, polyacrylic ester, polymethacrylic ester, polyamide, polyester, ABS resin, polyvinyl chloride, polyolefin, polysulfone, ethylene-vinyl acetate copolymer, and polychlorinated Vinylidene, fluororesins, etc.

In this invention, the ultraviolet absorber and antioxidant are
Although each can be used alone, it is preferable to use both together. As the ultraviolet absorber, benzotriazole-based, oxalic acid amide-based, benzophenone-based, and hindered amide-based ones are preferred. Furthermore, as the antioxidant, hindered phenol type antioxidants are preferred.

These ultraviolet absorbers and antioxidants are preferably contained in the C layer in an amount of 0.01% by weight or more, particularly 0.1 to 7.0% by weight, although it depends on the synthetic resin used.
It is preferable that the content is % by weight.

As mentioned above, the heat-sensitive reversible color-changing fabric used in the bordered garment of the present invention has a four-layer laminated structure.
It is not necessarily necessary that the entire surface has this structure, but it is sufficient that a part of it has this structure. It is also possible to combine a normal fabric that does not have heat-sensitive reversible discoloration with a fabric that has heat-sensitive reversible discoloration to change the pattern from plain to patterned or from patterned to plain based on changes in temperature. It is. Even if the entire surface of the fabric is heat-sensitive and reversibly discolored, by partially providing a heat insulating layer on the inside, the fabric can change from a plain pattern to a patterned fabric or from a patterned fabric to a plain pattern as the temperature changes, in the same manner as above. is possible.

In addition, another method of forming the handle is
This can also be achieved by locally destroying the microcapsules using heat, pressure, etc., as described in No. 51-35414.

Since the heat-sensitive reversible color-changing ink used in the present invention is encapsulated in microcapsules, it is possible to change the color to various colors depending on each temperature range. For example, (1) Ink that changes from white to colorless at -10℃ (2) Ink that changes from yellow to colorless at 0℃ (3) Ink that changes from blue to colorless at 10℃ (4) Ink that changes from red to colorless at 20℃ When layer B is formed by mixing four types of heat-sensitive reversible color-changing inks, each of which is encapsulated in microcapsules, with a synthetic resin, the color changes to gray below -10°C, -10 to 0.
Black at ℃, purple at 0-10℃, red at 10-20℃, 20
It turns colorless at temperatures above ℃, allowing you to enjoy an extremely wide variety of color changes.

Further, in the thermosensitive reversible color-changing fabric, it is necessary to provide the C layer outside the B layer when viewed from either the front or the back in order to improve the light resistance.

The heat-sensitive reversible color-changing laminated structure used in the present invention can further improve water repellency and abrasion resistance by providing a separate protective layer as the outermost layer, if necessary. As the protective layer, a synthetic resin layer having abrasion resistance, such as vinyl chloride, polymethyl methacrylate, polymethacrylate ester, polyamide,
ABS resin, polyvinylidene chloride, etc. are preferred.
The thickness of each layer varies depending on the purpose of use, but layer B is 10
-40μ, and the C layer is about 3-20μ.

Further, depending on the purpose of use, a matting agent such as titanium oxide or silicon oxide may be added to the layer constituting the outermost layer in an amount of about 0.1 to 10% by weight based on the outermost layer.

In addition, if a transparent fiber base material is used and the base material side is the outer surface, it can have the function of protecting the coating layer, and has durability against external forces such as abrasion resistance, kneading resistance, and scratch resistance. It is preferable because the properties are improved.

The method for applying each layer of the heat-sensitive reversible color-changing laminated structure used in the present invention can be direct coating, transfer coating, gravure coating, etc., and the method for removing the solvent can be either wet or dry.

In the present invention, border decoration is synonymous with trimming, and examples thereof include piping.
Furthermore, the width of the border decoration can be set arbitrarily. For example, when performing pumping, the thickness is preferably about 2 to 8 mm.

In addition to the collar, the areas to be decorated include the sleeves, body length, and pocket openings.

When sewing a jacket with white taffeta made of nylon 70D with a moisture-permeable coating (registered trademark Entrant), the heat-sensitive reversible color-changing fabric obtained as described above was used for the border decoration. That is,
The collar is 8mm wide, and the body and sleeve lengths are 15mm wide with decorative stitching, and the inner pocket openings are welt-stitched. FIG. 1 shows the fringe part of the jacket.

In this fringe-decorated garment, the color of the hem-decorated portion reversibly changed from the white color of the base material to yellow due to the temperature difference. In addition, the light fastness was grade 4 or above in the JIS L0842 fade test, and the JIS K6328 kneading resistance test showed no abnormality even after 1000 times of 1 kg, making it sufficiently durable for practical use.

(Effects of the invention) The heat-sensitive reversible color-changing non-waterproof border-decorated garment of the present invention has the feature that the border part changes color due to temperature changes. It became possible to enjoy a variety of color changes due to temperature differences, which was not possible with traditional fringe clothing. Furthermore, by combining the colors of the fastener, the color of the stitching shim thread, and the color of the buttons, an even greater variety of colors can be created. These effects are exhibited in ordinary men's wear, women's wear, children's wear, and casual wear.
