  The inventor of the present invention has a tendency that the thermal sensing time of the thermal sensation article containing the thermal sensation agent tends to be longer than that of the exothermic article containing the heat generating agent (for example, iron powder). In addition to the fact that the wearer is easy to feel itching, the thermal sensation article containing the warming agent has a condition of the wearer's skin (for example, the wearer's skin) compared to the exothermic article containing the exothermic agent (for example, iron powder) I found that there is a difference in how to feel the warmth depending on the degree of dryness of the skin. For example, when the wearer's skin is moistened with water, it is easier to maintain the swollen state of the stratum corneum of the wearer's skin, compared to when the wearer's skin is dry, The warming solution is likely to reach the TRP channel mainly present in keratinocytes (keratinocytes), so it is easy to feel the warming (the heat sensing time is short).

  Therefore, by providing the on-demand property to the thermal sensation article of the present disclosure, the wearer presses the portion overlapping the thermal sensation area of the thermal sensation article in the thickness direction of the thermal sensation article, thereby providing The warm feeling solution is released, and the warm feeling solution which has passed through the liquid permeable sheet reaches the wearer's skin and can be given a warm feeling by the wearer than before it is pushed in, and the wearer feels warmth You will be able to adjust.

  As a liquid-permeable sheet having lipophilicity, a material constituting the liquid-permeable sheet is treated with a lipophilic agent known in the art (for example, a lipophilic agent is coated, a lipophilic agent) Can be formed by As the above-mentioned lipophilic agent, fatty acid ester (for example, triglyceride), hydrocarbon (for example, linear hydrocarbon) is mentioned.

When the liquid-permeable sheet of the thermal sensation article of the present disclosure is a fabric, the on-demand property is imparted to the thermal sensation article of the present disclosure, the liquid-permeable sheet is preferably 0.005 to 0.060 g / It has a fiber density of cm ³ , more preferably 0.010 to 0.050 g / cm ³ , and more preferably 0.020 to 0.040 g / cm ³ . By adjusting the fiber density between the liquid-permeable sheet and the intermediate sheet, the warm-feeling article can have on-demand properties.
The measuring method of the said fiber density is mentioned later.

When the liquid-permeable sheet of the thermal sensation article of the present disclosure is a fabric, when the thermal sensation article of the present disclosure is provided with on-demand properties, the liquid-permeable sheet has a thickness of 30 g / cm ² when loaded. Preferably, it is 70% or less, more preferably 60% or less, and still more preferably 50% or less of the thickness under a load of 3 g / cm ² . By doing so, when the wearer pushes the thermal sensation article in the thickness direction, the liquid-permeable sheet is easily crushed, and the thermal sensation solution held by the liquid-permeable sheet is brought into contact with the wearer's skin As a result, the on-demand property of the thermal sensation article is improved.

When the liquid-permeable sheet of the thermal sensation article of the present disclosure is a fabric, when on-demand properties are imparted to the thermal sensation article of the present disclosure, the liquid-permeable sheet has a thickness of 10 g / cm ² when loaded. The thickness at a load of 3 g / cm ² is preferably 70% or more, more preferably 80% or more, and still more preferably 90% or more. By doing so, it becomes difficult for the liquid permeable sheet to be crushed under applied pressure such as clothing, and the applied pressure makes it difficult for the warm feeling solution held by the liquid permeable sheet to come into contact with the skin of the wearer, and consequently the warm feeling article It becomes easy to improve on demand.

Herein, the thicknesses at 30 g / cm ² , 10 g / cm ² and 3 g / cm ² load are measured as follows.

Then, the moisture of the wearer's sweat causes the stratum corneum of the wearer's skin to swell with moisture, making it easy for the warming solution to reach TRP channels mainly present in keratinocytes (keratinocytes). As a result, the heat sensing time becomes short, and it becomes difficult for the wearer to feel stagnation in the heat sensing time.
In addition, even when the liquid-permeable sheet contains a heat storage material or a far infrared radiation material, the wearer can easily sweat, and the moisture of the wearer's sweat causes the stratum corneum of the wearer's skin to be moist Swelling and warming solutions are likely to reach TRP channels mainly present in keratinocytes (keratinocytes).

By doing so, moisture, water vapor and the like present on the warm feeling area and the wearer's skin in contact with the warm feeling area permeate through the liquid impermeable sheet and are hardly discharged out of the warm feeling article. The stratum corneum of the skin is easily retained in a swollen state with water, and the warming solution is likely to reach TRP channels mainly present in keratinocytes (keratinocytes). As a result, the heat sensing time becomes short, and it becomes difficult for the wearer to feel stagnation in the heat sensing time.
