Description

  The present invention relates to a laminate used by being integrated with clothing, and particularly relates to the development of a laminate capable of experiencing a cool feeling.

  In recent years, various contrivances have been made to lower the perceived temperature of people wearing sportswear, jerseys, clothing such as summer underwear and pajamas. For example, shirts with pockets for cooling agents (cooling agents) to relieve heat, cool clothing that can provide a cool effect by using fabric with good heat dissipation, and a cool effect can be obtained by including moisture. There are clothes using fiber structures to which sugar alcohol is adhered with good durability, and the effect of lowering the temperature of sensation is realized by various methods. Specific examples of clothing using these technologies are shown below.

-Shirts with coolant pockets: Cooling agents by providing pockets for storing coolant (cooling agents) in the neck and underarms of shirts, etc., in order to relieve heat caused by rising body temperature during hot summer months. Has disclosed a garment (Patent Document 1) that allows the user to experience coolness by cooling the subcutaneous blood vessel.

・ Cool sensation clothing: For clothing such as T-shirts, the use of fabrics with good heat dissipation as a heat countermeasure reduces the sensed temperature, and elderly people whose body temperature regulation ability is significantly reduced are affected by cooling. In order to prevent too cold (too cold), a cool sensation garment (Patent Document 2) is disclosed that uses a fabric having good heat dissipation only in a part of the chest, etc., in which the sweating function is not lowered with age.

-Fiber structure: By forming a film containing sugar alcohol and inorganic particles having an average particle diameter of 5 to 400 nm on the fiber surface, an excellent cool feeling and washing durability can be imparted to the fiber structure. It has been disclosed that a cool feeling can be experienced by using it in clothing (Patent Document 3).

JP 2013-32603 A JP-A-11-247011 JP 2007-70744 A

  However, although a cool feeling can be experienced by the above-described method, for example, in a shirt with a coolant pocket (Patent Document 1), a cool feeling cannot be obtained without a cooling agent. In addition, the cool clothing (Patent Document 2) uses a fabric with good heat dissipation, which is partly different from the base fabric, so it takes time and cost significantly for mass production compared to general clothing. For example, when it is used for a school-designated jersey or uniform, it affects many people.

  On the other hand, the above-mentioned problems can be solved by adding a function that allows a cool sensation to be applied to a laminate that can be printed and pasted on general clothing, but conventionally a laminate for clothing has been applied to clothing. When printing or pasting, it is common to create a film with excellent wear and water resistance on the color layer (the surface of the laminate) to increase the fastness to washing, stretching and cracking. Is. In such a structure, the laminated body contains moisture such as moisture in the air and sweat of people wearing clothes, so that the function that can provide a cool feeling effect is naturally a film with excellent water resistance. Because it is blocked, it cannot be realized.

  And, like the above fiber structure (Patent Document 3), it is possible to simply use a fiber to which sugar alcohol having a cool feeling function is attached for clothing, but although it has good washing durability, for example, Although it is suitable for use in bedding, etc., when it is used in clothing that must be washed after wearing, there is a possibility that the cool sensation will fall off due to excessive washing, and the cool sensation effect may be reduced. Even if a film with excellent water resistance is applied in the same way as a conventional laminate for clothing to improve the washing resistance, as described above, it can not contain moisture and can obtain a cool feeling effect. I can't. In addition, according to the investigations by the present inventors, a laminate for clothing having a function of lowering the temperature at which the skin is touched by containing moisture has not been developed so far.

  Therefore, the present inventors focused on a laminate for clothing that can be easily printed and retrofitted to conventional clothing, and the laminate has a function of allowing a cool feeling to be experienced when it contains moisture, and The present inventors have found that the above-mentioned problems can be solved by forming a film capable of maintaining washing resistance, and have developed the present invention.

  The present invention has been made in view of the above-described problems of the prior art, and the purpose of the present invention is to provide a cool feeling when the laminate contains moisture after printing or pasting the laminate to clothing, And it is providing the cool feeling laminated body which also maintains the fastness with respect to washing and expansion / contraction.

  In FIG. 1, sectional drawing of the cool feeling laminated body 10 regarding this invention is shown. As shown in FIG. 1, the cool laminate 10 according to the present invention includes three layers, and includes a surface layer 11, an intermediate layer 12, and an adhesive layer 13. Further, the surface layer 11 and the intermediate layer 12 each have a cooling agent 14, and depending on the case, the surface layer 11 and the intermediate layer 12 may have only the intermediate layer 12 or only the surface layer 11. The surface layer 11 plays a role as a color layer, and a general fluorescent agent, paint, dye, aluminum powder, aluminum paste, pearl powder, or the like can be used as the color material. The intermediate layer 12 serves as a backup layer (assisting as a color layer or assisting a cool feeling function) that functionally assists the surface layer 11. It is particularly preferable that the mid layer 12 as the backup layer contains the cooling agent 14. Moreover, although illustration is abbreviate | omitted, you may include a deodorizer in both or any one of the surface layer 11 and the intermediate | middle layer 12. FIG.

<Thermosetting resin>
The thermosetting resin here refers to a resin that cures by causing a crosslinking reaction by heating the initial polymer. Therefore, the thermosetting resin has a property that it does not soften even if it is heated again after the crosslinking reaction (after heating). Examples of the thermosetting resin include urethane resin (PU), epoxy resin (EP), phenol resin (PF), urea resin (UF), melamine resin (MF), unsaturated polyester resin (UP), silicon resin ( SI). Among these, urethane resin (PU) is particularly preferable from the viewpoints of compatibility with the cooling sensation agent and the powdery thermoplastic resin, cost, and the like. In addition, the said thermosetting resin is not limited to single, and may use 2 or more types together.

<Thermoplastic resin>
A thermoplastic resin is not a structure that crosslinks between polymers like a thermosetting resin, but is softened and plasticized by heating above a certain temperature (100 ° C. to 300 ° C.), and solidifies when cooled. Represents resin. Examples of the thermoplastic resin include polyurethane resin (TPU), ABS resin (ABS), polyamide (PA), polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PC), and polyacetal (POM). , Polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), polyether sulfone (PES), polyphenylene ether (PPE), polysulfone (PSF), polyvinyl chloride (PVC), polyether ether ketone ( PEEK) and liquid crystal polymer (LCP). Among them, polyurethane resin (TPU) is particularly preferable from the viewpoint of resin characteristics and cost. In addition, the said thermoplastic resin is not limited to independent, You may use 2 or more types together.

<One-part resin>
The one-component resin represents a resin that absorbs moisture in the air, or evaporates and dries to cause a crosslinking reaction to cure. Accordingly, the one-component resin has a property that it does not soften again after the crosslinking reaction. Examples of the one-component resin include a moisture curable resin and an evaporative drying resin. Among these, evaporative drying type resins are particularly preferable from the viewpoint of resin characteristics and cost. The one-component resin is not limited to a single type, and two or more types may be used in combination.

<Cooling agent>
The sugar alcohol contained in the cool sensation agent only needs to have a cool feeling effect by containing moisture, and examples thereof include xylitol, sorbitol, mannitol, erythritol, maltitol, lactitol, glycerol and the like. Of these sugar alcohols, xylitol or erythritol is particularly preferable from the viewpoint of endothermic properties and stable supply.

<Crosslinking agent>
The cross-linking agent in the present invention refers to a substance that causes a cross-linking reaction with a polymer resin under certain conditions. Curing of the resin after the crosslinking reaction can be adjusted by the amount of the crosslinking agent. In the present invention, it is preferable to use a polyisocyanate, particularly a blocked isocyanate, as the crosslinking agent.

Adhesive Layer The adhesive layer 13 in the present invention only needs to exhibit an adhesive action for attaching the cool feeling laminate 10 to the garment 1, and a commercially available adhesive or the like can also be used.
However, the cool-feel laminate 10 needs to have chemical resistance to the load during washing and the detergent used during washing, and the adhesive layer 13 is preferably made of a thermoplastic material or a hot melt material.
Furthermore, among the thermoplastic materials, from the viewpoint of compatibility with the resin layer 11 or the intermediate layer 12, a urethane-based resin is preferable for the adhesive layer 13, and it is particularly preferable to use a thermoplastic polyurethane-based resin.

EXAMPLES Hereinafter, although an Example demonstrates this invention further more concretely, unless it exceeds the meaning of this invention, it is not limited to the following Examples at all.
First, the cool feeling effect by the cool agent used for a cool feeling laminated body was confirmed.

(Confirmation of cool sensation effect by cool sensation agent)
The cool sensation laminate according to the present invention obtains a cool sensation effect by utilizing the characteristics of sugar alcohols such as xylitol and erythritol. Therefore, the cool feeling effect by sugar alcohol was confirmed under the following conditions.
・ Test method Two specimens are put together, four sides are sewn together to make a test piece, and a thermocouple type temperature sensor is inserted in the center of the test piece. About 0.2 ml of water is dropped into the center of the test piece in an atmosphere of about 36 ° C., and the temperature of the wet part is measured for 10 minutes. Here, the processed product is a dough containing sugar alcohol, and the unprocessed product is a dough not containing sugar alcohol.

・ Environmental conditions Room temperature: 36 ± 2 ℃
Humidity: 60 ± 4% RH
Water temperature: 36 ° C
Thermometer: Thermocouple type temperature sensor

[Table 1]

420 27.8 32.1
480 27.9 32.1
540 27.8 32.1
600 27.7 32.1

  As shown in Table 1, it can be seen that there is a clear temperature difference in the measured temperature between the processed product (dough containing sugar alcohol) and the unprocessed product (dough not containing sugar alcohol). The temperature difference gradually increases after 120 seconds, and a temperature difference of about 4 ° C. occurs after 180 seconds, and this state is maintained until 600 seconds. Thus, it has been found that the use of a sugar alcohol such as xylitol or erythritol as a cool sensation agent provides a certain cool feel effect by containing moisture.

(Confirmation of deodorizing effect by deodorant)
The cool feeling laminated body which concerns on this invention can obtain a deodorizing effect using an adsorption | suction effect | action by putting a deodorizing agent like silver zeolite into a cool feeling laminated body with a cooling agent. Therefore, the deodorizing effect by silver zeolite was confirmed under the following conditions.
* Based on the instrument analysis manual of the Textile Evaluation Technology Council.
Test Method (A) Gas Chromatograph Method The odor component solution is dropped into a 500 mL Erlenmeyer flask containing the test piece, sealed, and then measured for 2 hours after standing.

Deodorant: Silver zeolite Initial gas concentration: Isovaleric acid About 38ppm
Measurement time: 2 hours later Sample size: 50 cm ²

[Table 2]
Sample reduction rate (%)
Isovaleric acid
Cool feeling laminate 92

  As shown in Table 2, with isovaleric acid used as an odor component, a large deodorizing effect (decrease rate) with a reduction rate of about 90% or more could be obtained. Thus, by using silver zeolite as a deodorant, it was possible to obtain a good deodorization effect due to physical adsorption and chemical action. Here, it is expected that the deodorizing effect due to the adsorption action is lost when it is saturated. However, the odor actually felt by humans is very low in concentration and takes time to reach saturation. That is, the deodorizing effect lasts for a long time.

Next, the evaluation method used in the present Example of the cool feeling laminated body which concerns on this invention is demonstrated.

As shown in Table 3 above, it can be seen that Example 1, Example 3, and Example 5 have an excellent cool feeling effect. Moreover, although Example 2 and Example 4 have acquired the stable cool feeling effect, it turns out that there are few cool feeling effects compared with Example 1, Example 3, and Example 5. FIG. This is because Example 2 has a smaller amount of the cool sensation agent compared to Example 1, Example 3, and Example 5. From this, the cool effect obtained by the influence of the amount of the cool sensation agent changes. I understood. In Example 4, a 10% cross-linking agent was added to the thermoplastic resin, and the film was formed by heat treatment. However, since it is a suitable film that can contain moisture, a cool feeling effect can be obtained. It was.
In Example 3, the cool sensation laminate was produced by printing directly on the fabric, but the same cool sensation effect as in Example 1 was obtained, there was almost no difference in the cool sensation effect depending on the production method, and a stable effect was obtained. Obtained.
On the other hand, in Comparative Example 1 and Comparative Example 2, although the temperature dropped temporarily due to the dripping of water, the temperature immediately rose and almost no cool feeling effect could be obtained. This is because Comparative Example 1 uses a resin in which 20% of a crosslinking agent is added to a thermoplastic resin, so that the surface is completely coated, and moisture does not reach xylitol and erythritol, which are cooling sensations. Therefore, it turns out that the cool feeling effect is not acquired. Moreover, since the xylitol and erythritol which are cooling agents are not put into the resin mixture in the comparative example 2, it is anticipated that the cooling effect is not obtained even if moisture is contained in the cooling laminate. From this, it is understood that the cool feeling effect is obtained only when the cool feeling agent is contained.

  According to the test result of the cool sensation effect, it was stable only when the resin of the specific composition and the thermosetting resin and the powdered thermoplastic resin were mixed, and the cool sensation agent was included in the resin layer. It has been found that a cool feeling effect can be obtained.

Overall Evaluation Good Good Good Good Good
○: Indicates that the same cool feeling effect is obtained after washing as before washing.
X: The cool feeling effect before washing after washing is hardly obtained.

As shown in Table 4 above, Examples 1 to 5 have good cool feelings even when the number of times of washing is 5 or 10 and the state where no washing is performed (when the number of times of washing is 0). It can be seen that the effect is obtained and the washing resistance is excellent. This indicates that the washing resistance and the wear resistance (fastness) of the cool-sensitive laminate are firmly maintained by curing (coating) due to the effects of heat treatment, humidity, and drying. In general, it is said that a cool sensation fabric in which a cool sensation process is applied to the fabric tends to cause the cool sensation to flow down little by little every time it is washed, resulting in a weakening of the cool sensation effect.
On the other hand, it can be seen from the test results that the resin layer of the present invention has the same washing resistance as that of a conventional laminate in which a surface layer is provided with a film having excellent water resistance.

(Recovery of cool effect and deodorant effect)
As described above, it has been found that the cool feeling laminate according to the present invention has a cool feeling effect and also maintains the washing resistance. Moreover, it turned out that a deodorizing effect is simultaneously obtained with a cool feeling effect by putting a deodorizer into a cool feeling laminated body. Here, the functional durability (recovery of cool feeling effect and deodorizing effect) of the cool feeling laminate according to the present invention will be described using the following test results.

First, a test on recovery of the cool feeling effect of the cool feeling laminate according to the present invention was performed.
In this test, before washing (cool feeling laminate before washing) is a cool feeling laminate already in a moisture absorbing state, and after washing (cool feeling laminate after washing) is equivalent to the above-described washing resistance test. It is the cool feeling laminated body which passed through the washing and drying process.

・ Test method Two specimens are put together, four sides are sewn together to make a test piece, and a thermocouple type temperature sensor is inserted in the center of the test piece. About 0.2 ml of water is dropped into the center of the test piece in an atmosphere of about 36 ° C., and the temperature of the wet part is measured for 10 minutes. Here, the processed product is a dough containing sugar alcohol, and the unprocessed product is a dough not containing sugar alcohol.

・ Environmental conditions Room temperature: 36 ± 2 ℃
Humidity: 60 ± 4% RH
Water temperature: 36 ° C
Thermometer: Thermocouple type temperature sensor

  As shown in Table 5 above, the cool-feel laminate before washing dropped water in the same manner as the unprocessed product, but the temperature dropped temporarily, but the temperature immediately rose, and almost no cool-feel effect was obtained. I couldn't get it. On the other hand, it can be seen that the cool feeling laminate after washing has an excellent cool feeling effect. That is, it can be said that the cool feeling effect is recovered by adding a washing / drying process to the cool feeling laminate before washing which is already in a hygroscopic state in the same manner as general clothing. Therefore, the cool feeling laminate according to the present invention can obtain a good cool feeling effect any number of times.

Next, the recovery of the deodorizing effect by the cool laminate according to the present invention containing a deodorant such as silver zeolite was confirmed.
In this test, before washing is a cool feeling laminate that has already adsorbed odor components, and after washing is a cool feeling laminate that has undergone a washing / drying process equivalent to the washing resistance test. .
Moreover, the following test method is based on the instrument analysis implementation manual of the fiber evaluation technical meeting.

Test method (B) Detector tube method 3 L of odor gas is sealed in a sampling bag containing a test piece, and the gas concentration after standing for 2 hours is measured with a detector tube.

Deodorant: Silver zeolite Initial gas concentration: Ammonia 100ppm
Acetic acid 30ppm
Measurement time: 2 hours later Sample size: 100 cm ²

[Table 6]
Sample reduction rate (%)
Ammonia Acetic acid
Cool feeling laminate (before washing) 61 88
Cool feeling laminate (after washing) 88 96

  As shown in Table 6, with respect to ammonia as an odor, the decrease rate of odor was 61% in the cool feeling laminate before washing, whereas the decrease rate was 88% in the cool feeling laminate after washing. You can see that it has recovered (increased). Similarly, for acetic acid as an odor, the decrease rate was 88% in the cool feeling laminate before washing, whereas the decrease rate was recovered (increased) to 96% in the cool feeling laminate after washing. I can see that That is, similarly to the recovery of the cool feeling effect described above, by performing washing and drying, recovery of the deodorizing effect can be expected, and the cool feeling laminate of the present invention can maintain the deodorizing effect many times. .

As described above, the cool sensation laminate of the present invention can be easily printed and affixed to clothing, has a cool sensation effect due to moisture in the air, etc., and maintains washing resistance, and further allows the user to It also has the desired design properties. Moreover, the cool feeling laminated body of this invention can also be affixed on the inner side of clothes, and in this case, it is possible to obtain clothes capable of providing a cool feeling effect without changing the design of conventional clothes.
Furthermore, as above-mentioned, by adding a deodorizer to the cool feeling laminated body of this invention, a deodorizing effect can be obtained simultaneously with a cool feeling effect. That is, by adding a deodorant to the above Examples 1 to 5, it is possible to obtain a cool feeling laminate capable of simultaneously solving the two problems of measures against cool feeling such as a hot summer day and measures against deodorization. And the cool feeling laminated body of this invention can maintain a favorable cool feeling effect and a deodorizing effect by washing and drying.

  The cool sensation laminate according to the present invention can be easily formed on clothing such as sportswear, jerseys, uniforms, T-shirts, shirts, pajamas, tank tops, camisole, underwear by printing or thermocompression bonding, In addition, since the cool laminate includes moisture such as moisture in the air and sweat that could not be realized with a conventional laminate for clothing, a person wearing clothing has a function of experiencing a cool feeling. At the same time, it has the characteristics of maintaining fastness such as wear resistance and water resistance.
