BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a dye for producing a body temperature-sensitive discoloration garment of the present invention and a method for producing a body temperature-sensitive discoloration garment using the same.
Fig. 2 and Fig. 3 show an embodiment of the body temperature sensitive discoloration garment manufactured by the present invention. Fig.
4 is a view showing another embodiment of the body temperature sensitive discoloration garment manufactured by the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The dyes for the manufacture of thermosensitive discoloration garments of the present invention comprise 5 to 10% by weight of a sensitizing dye, 84 to 90% by weight of water, 1 to 9% by weight of a fixing agent, and 0.1 to 5% by weight of a thickener, based on the total weight of the dye.

The thermosensitive dye is a water-soluble thermochromic pigment having no hydrophilic and hydrophobic groups in the molecule and having no affinity with fibers.

The thermochromic pigment is a pigment whose color changes as the molecular structure changes according to the temperature. The principle is that the molecular structure of a thermochromic pigment reacts to the ambient temperature and changes its molecular structure. When the molecular structure changes, the distribution of electrons surrounding the molecule changes naturally. The color of the material depends on the distribution of electrons. Because the molecule absorbs light of a specific color depending on the electron distribution, the change in the molecular structure soon appears as discoloration.

The thermochromic pigment is a reversible temperature discolorant pigment that changes color according to changes in external temperature and returns to its original color when it returns to its original temperature. In addition, the temperature-sensitive pigment preferably has a basic color when the set temperature is not reached, and is preferably for a high-temperature milky white color when the set temperature is reached.

Preferably, the thermochromic pigment is a mixture of at least two of a thermochromic pigment reacting at 35 ° C or higher, a thermochromic pigment reacting at 37 ° C or higher, a thermochromic pigment reacting at 38 ° C or higher, or a thermochromic pigment reacting at 40 ° C or higher.

Examples of the thermochromic pigment that reacts at 35 ° C or higher include black, magenta, red, and yellow thermochromic pigments, and the thermochromic pigment that reacts at 37 ° C or higher include thermochromic pigments such as black and yellow, There are thermochromic pigments such as blue, blue, and pink, and thermochromic pigments such as blue, orange, red and yellow which react at 40 ° C or higher.

For example, the mixing of the sensitizing pigment may be performed by mixing the yellow sensitizing pigment among the sensitizing pigments reacting at 35 ° C. or higher and the blue sensitizing pigment among the sensitizing pigment reacting at 38 ° C. or higher.

In this case, a green color mixture of yellow and blue appears at a temperature below 35 ° C., and a blue color appears when the temperature is below 35 ° C. and below 38 ° C., and when the temperature is 38 ° C., the blue color disappears and becomes milky white.

The thermochromic pigment is preferably in the form of a microcapsule or a slurry.

The microcapsule type is excellent in the ability to stick to the fabric material, so that even when the clothes are washed, the discoloration function is not lost.

The thermochromic pigment is odorless and harmless to the human body, so it can be applied to infant clothes.

The sensitizing pigment is mixed with a dispersing agent and distilled water and milled to produce a nanomolecule, which is converted into a thermal dye. Thermal dye is water-soluble and therefore has affinity with fiber.

Since the thermochromic pigment does not dissolve in water, it contains a dispersant to improve its solubility, and is finely crushed and milled to disperse evenly in water. The thermochromic pigment must be sufficiently dissolved in water to enable the expression of a dark color.

Water is distilled water. Although water contains tap water, surface water and ground water, they contain a lot of impurities such as calcium, magnesium, iron, solid, organic, acid, and alkali. It is preferable to use distilled water containing no impurities.

The dispersing agent enables the dye to be stably dispersed in water when the thermosensitive pigment is mixed with water. The dispersant disperses the thermochromic pigment which is not soluble in water in a state close to the colloid.

Surfactants may be used instead of dispersants.

The thermosensitive dye is preferably prepared from nanoparticles by mixing 20 to 50% by weight of a thermosensitive pigment, 0.05 to 5% by weight of a dispersant, and distilled water.

If the thermochromic pigment is contained in an amount of less than 20% by weight based on the total weight of the thermosensitive dye, the effect of color development is insufficient, and if it exceeds 50% by weight, uniform dispersion in distilled water is difficult.

When the dispersing agent is contained in an amount of less than 0.05% by weight based on the total weight of the thermosensitive dye, the dispersing effect is insufficient. When the dispersing agent is more than 5% by weight, the formulation of the thermosensitive dye is unstable and is not efficient.

The thermosensitive dye is contained in an amount of 5 to 10% by weight based on the total weight of dyes for fabricating thermosensitive discoloration clothes.

When the thermosensitive dye is contained in an amount of less than 5% by weight, it is difficult to obtain a clear color upon dyeing. When the thermosensitive dye is used in an amount exceeding 10 parts by weight, the content of other components is relatively small.

The water component is contained in an amount of 84 to 90% by weight based on the total weight of the dyes for fabricating the body temperature sensitive discoloration clothes. The water component is preferably a water component having a gel viscosity and viscosity of the transparent rubber component. That is, the water component means a transparent gel of a rubber component.

The water component is intended to impart viscosity to the dye.

If the water content is less than 84% by weight, the effect is insufficient. If the water content is more than 90% by weight, the relative content of the thermal dye and other components is decreased, and it is difficult to obtain a clear color in dyeing, .

The fixing agent is contained in an amount of 1 to 9% by weight based on the total weight of the dyestuff for fabricating the thermosensitive discoloration clothes. Preferably, the fixing agent is included at 5 wt%.

The fixing agent chemically binds the dye to the fabric material so that the dyeing can be carried out well. It is preferable that the fixing agent is a fiber fixing agent or a crosslinking agent for printing.

For example, the fixing agent may be at least one selected from the group consisting of sodium carbonate, heavy chromium, potassium oxygen, and a binder.

If the fixing agent is contained in an amount of less than 1% by weight based on the total weight of the dye, the dye may not chemically bond to the material of the raw material. If the amount exceeds 9% by weight, the dyeing may not be uniform and unevenness may occur in the raw material.

The thickening agent comprises 0.1 to 5% by weight based on the total weight of the dyestuff for fabricating the thermosensitive discoloration clothes. Preferably, the thickener is included in an amount of 1% by weight.

The thickener is for controlling the viscosity of the dye. The thickening agent is preferably a fiber thickening agent, or a thickening agent for printing.

The thickener contributes to impart a viscosity such that the dye is not spilled and the dye is cleanly removed by squeegee.

If the viscosity of the dye is low, the dye may flow down during dyeing, making it impossible to work. When the viscosity is high, the sharpness of the color is enhanced. However, the dyeing may be difficult to squeeze and the dye may adhere to the fabric material.

The dyeing process utilizes prints, and printing involves scraping off the dye on the screen and squeegeeing the dye, unlike dipping, which dips the fabric into the dye container. Therefore, it is important to maintain a proper viscosity since the dyeing process becomes impossible when the liquid state of a dilute viscosity such as the dye of the infiltration occurs.

When the thickener is contained in an amount of less than 0.1% by weight based on the total weight of the dye, it is difficult to obtain the viscosity of the dye and it is difficult to obtain a clear color, and when it exceeds 5% by weight, the viscosity is high and the dyeing process becomes difficult.

If the viscosity of the dye is high, the dye does not naturally penetrate into the fabric material, so the dye can not be dyed in the entire fabric material, and only the surface can be dyed, causing problems in uniform dyeing and difficulty in squeezing.

The dyes for fabricating thermosensitive discoloration garments contain 5 to 10% by weight of a thermosensitive pigment as a water-soluble thermosensitive dye, 84 to 90% by weight of a viscous gel component of a transparent rubber component, 1 to 9% by weight of a fixing agent, 0.1 to 5% by weight.

The manufactured dyes for fabricating body temperature sensitive discoloration garments can be printed on fabrics and dried to produce discoloration garments for detecting body temperature.

The dyes for fabricating the thermosensitive discoloration garment can be printed on the whole of the fabric material and can be printed on the fabric part to form a pattern on the fabric material.

The fabric material is preferably cotton or polyester or a mixture thereof.

In addition, the fabric material may be in the form of a garment made for infants. In this case, the dyes for fabricating the body temperature discolorable garment are printed and dried to form patterns on the clothes for infants, thereby producing the body temperature sensitive discoloration clothes.

Detecting body temperature When dyeing garments for the manufacture of clothing, it is desirable to print the dyes at a place where the body temperature changes rapidly when the baby has an abnormality in the body to form a pattern. For example, it can be printed by forming a pattern on at least one part of the infant's chest, armpit, or neck.

The print can be printed on the fabric material using the automatic screen printing machine. Detection of body temperature by printing Dye for garment manufacture is attached to fabric material.

The print includes a process of applying a dye on the screen and scraping it with a squeegee so that the dyeing is evenly applied to the fabric material.

Drying is the detection of body temperature discoloration. It is absorbed by the hot air drying, drying by radiant heat using infrared ray, and the high frequency wave, by charging the cloth material printed with dye for clothing into a closed drying chamber and sending hot air to evaporate moisture. Or by high-frequency drying in which heat is used to dry the substrate.

The drying is preferably carried out at a temperature of 120 to 140 DEG C for 10 to 30 minutes.

Detection of body temperature by drying Dyes for clothes fabrication are fixed on the fabric material.

Detection of body temperature by primary drying Deterioration Detection of body temperature by passage of hot air through 90 ~ 110 ℃ of dyed fabrics to which clothes dyeing dyes have been fixed. Secondary drying to fix dyes for clothing fabrics more firmly can do. Then, the discoloration function is not lost even if the cloth material is washed by improving the ability of the dye for clothes manufacturing to stick to the fabric material.

The solution stability, durability and fixation of dyes for fabricating discoloration of body temperature were tested and shown in Table 1 below.

Hereinafter, the operation of the present invention will be described with reference to Examples and other Examples.

[Example]

As shown in FIG. 1, a thermosensitive dye, a dispersant, and distilled water are mixed to prepare a thermosensitive dye. The thermosensitive dye was mixed with a water component, a fixing agent and a thickening agent to prepare a dye for discoloration clothing.

Specifically, 40 parts by weight of a thermosensitive pigment, 2 parts by weight of a dispersant, and 58 parts by weight of distilled water were mixed and diluted (milled) to prepare a thermosensitive dye of a nanomolecule. By weight of a water component, 5% by weight of a fiber fixing agent and 1% by weight of a fiber thickener. The blending proceeded at room temperature.

In the production of thermochromic dyes, the temperature-sensitive pigment has a yellow color at less than 35 ° C., a yellow color temperature of 35 ° C. which becomes soft milky white when the yellow color disappears at more than 35 ° C., a blue color at less than 38 ° C., The milky white 38 &lt; 0 &gt; C blue sensitizing pigment was mixed.

Sensitive dyeing clothing fabric prepared by blending a thermosensitive dye, a gel viscosity of a transparent rubber component, a viscous water component, a fiber fixing agent, and a fiber thickener, was dyed in such a manner as to print on a fabric material.

The material of the fabric was made of cotton material for infants.

After the dyeing, the clothes were dried through primary and secondary drying to obtain a body temperature sensitive discoloration garment.

The drying was carried out at a temperature of 130 DEG C for 20 minutes and then for a secondary drying to pass through a passage through which hot air at 90 DEG C was supplied.

The manufactured body temperature sensitive discoloration garment is identified in Figs. 2 and 3.

As shown in FIG. 2 and FIG. 3, when the temperature-sensitive pigment of 35 ° C. yellow and 38 ° C. blue is mixed, the yellow color disappears at the current temperature of 35 ° C. or 37 ° C., only the blue color is displayed, The blue color disappears and becomes milky white.

Therefore, when the body temperature is 38 ° C, the color of the clothes or the patterns drawn on the clothes disappear, so that the state of the body can be easily recognized.

When the temperature is lower than 35 ° C, both yellow and blue are displayed, and green appears.

The fabricated body temperature sensing discoloration clothes were washed five times and then tested for discoloration according to body temperature.

As a result of the experiment, the function of discoloration was maintained in three stages according to the body temperature of the infant even after washing five times. This is because the use of a fixing agent and drying two times after the dyeing, the dyestuff for fabricating the discoloration garment firmly adhered to the fabric material, preventing the heat-sensitive pigment from being damaged or lose the discoloration function during washing.

The body temperature detecting discoloration clothes manufactured by the above-described process can immediately recognize and respond quickly to sudden abnormal symptoms such as fever when the baby, infant, and child wear it.

In addition, the body temperature discoloration clothes can be applied to patient clothes such as elderly nursing care hospitals and general hospitals to monitor health status from time to time.
