Further, instead of the stretchable sheet, a rubber thread as a holding member may be provided.

  The front waistline portion and the rear waistline portion are each provided with a high heat retention region R1 and a low heat retention region R2 having a heat retention rate lower than that of the high heat retention region. The high heat retention region R1 is a region having a heat retention rate of 29% or more and 60% or less. FIG. 1 shows the high heat retention region R1 and the low heat retention region R2 with different oblique lines.

  The high heat retaining region R1 is disposed in a portion of the front waistline that hits the wearer's abdomen, a portion of the front waistline that hits the wearer's buttocks, and a portion of the rear waistline that hits the base of the buttocks. The low heat retention region R2 is a portion of the front waistline that overlaps with the absorbent main body, a portion of the rear waistline that overlaps with the absorbent main body, and a portion of the rear waistline that is behind the absorbent main body and corresponds to the buttocks. It is arrange | positioned in the site | part behind the area | region.

  The high heat retention region is configured to have a relatively high heat retention rate by disposing an elastic sheet, or is configured to have a relatively high heat retention rate by disposing a sheet material having a hygroscopic heat generating material. The sheet material having the heat storage and heat insulation material is arranged to have a relatively high heat insulation rate, or the sheet material having the far infrared radiation material is arranged to have a relatively high temperature insulation rate. Or In the disposable diaper of the present embodiment, at least one of the first stretchable sheet 71, the second stretchable sheet 72, the first non-stretchable sheet 73, and the second non-stretchable sheet 74 is a moisture-absorbing heat generating material, a heat storage and heat retention. It is configured to include at least one of a material and a far infrared radiation material.

  Examples of the far-infrared radiation material include alumina-based ceramics, zirconium-based ceramics, and silicon-based ceramics that efficiently radiate far-infrared rays in a low temperature range of 20 to 40 ° C. The wearer can be warmed by emitting far-infrared rays from the far-infrared emitting material.

  As the hygroscopic heat generating material, for example, acrylate fiber and wool are used. As other moisture-absorbing heat generating materials, cupra, rayon, etc. are conceivable, and these materials can be used instead of ex or wool. Moreover, long fibers may be used instead of blended yarns, and fiber materials such as nonwoven fabrics and textiles may be used. The hygroscopic exothermic material increases heat generation and warms the wearer.

  The heat storage and heat retaining material is a highly efficient substance that absorbs a specific wavelength of sunlight and converts it into heat energy. Specifically, zirconium can be exemplified.

  The heat retention rate in the present invention can be measured as follows.

  (1) KES-F7 precision rapid thermophysical property measuring device manufactured by Kato Tech Co., Ltd. Thermolab II is prepared, and the room temperature is adjusted to 20 ° C. and the humidity is adjusted to 60% RH.

  (2) When measuring the heat retention rate of the disposable diaper, centering on the center of the excretory opening contact area, the direction perpendicular to the longitudinal direction (hereinafter referred to as the direction perpendicular to the longitudinal direction) is simply “ Cut a 12 cm sample (sometimes referred to as “orthogonal direction”).

  (3) The sample is attached to the sample frame attached to Thermolab II with double-sided tape.

In the case of disposable diapers, the sample is affixed to the sample frame according to the normal procedure of the measuring device, and then the sample is placed on the shorts with double-sided tape so that the sample comes to the center of the sample frame. paste.

  (4) In Thermolab II, the wind speed of the wind tunnel is set to 30 cm / second, and the temperature of BT-Box is set to 30 ° C.

  (5) The amount of heat Qd required to keep the temperature of the sample frame on which the sample is attached at 30 ° C. is measured.

  (6) Measure the amount of heat Q0 required to keep the temperature of the sample frame at 30 ° C. in the absence of a sample. In the case of disposable diapers, the amount of heat Q0 was measured with only the sample frame placed on the BT-Box, and in the case of a sanitary napkin, the sample frame with shorts attached was placed on the BT-Box. The amount of heat Q0 is measured in the state.

  (7) The heat retention rate is calculated according to the following equation (1).

Thermal insulation rate (%) = 100 × (Q0−Qd) / Q0 formula (1)
When the disposable diaper configured in this way is attached to the wearer, the high heat retaining region R1 of the front waistline portion hits the wearer's stomach and buttocks, and the wearer's stomach and buttocks can be warmed. Moreover, the low heat retention area | region R2 of a back waist part hits a wearer's buttocks, and can wear a wearer's stomach and buttocks. On the other hand, since the low heat retention area | region R2 is provided in the part which hits a wearer's inseam, it can suppress that an inseam is heated too much.

(2) Actions / effects For example, the wearer can feel the warmth of the mother when held by the mother, but the wearer loses the warmth when laid on a bed, etc. I can't. However, when there is a high heat retention region having a heat retention rate within a predetermined range, and the high heat retention region is held by the wearer's body by the holding member, the part corresponding to the high heat retention region is separated from the mother or the like Even so, infants can easily experience the warmth of their mothers and the like. Furthermore, the baby's own body temperature can be positively maintained and a heat retaining effect can be exhibited.

  By providing the high heat retention region and the low heat retention region together, the wearer can easily feel that a part (high heat retention region) is kept warm even when the wearer is away from the warmth of the mother. Accordingly, even when the mother is away from the mother or the like, a state in which the mother's warmth remains can be realized in a pseudo manner, and it is easy to maintain a comfortable sleep of the infant.

  Moreover, when a heat retention rate is made too high in the disposable diaper having an absorbent body, there is a risk of stuffiness. However, discomfort is less likely to occur by disposing a region having low heat retention, and discomfort due to excessive heat accumulation is less likely to occur by setting the heat retention rate lower than 60%.

  Further, as a result of various verifications by the present applicant, it was found that the heat of the diaper is easily retained when the heat retention rate of the high heat retention region R1 is 29% or more.

  In addition, as a result of intensive studies by the applicant, infants are likely to settle down and sleep well when their abdomen is kept warm by placing a futon on the abdomen or a mother's hands on the abdomen. all right. The disposable diaper according to the present embodiment can keep warm the part that hits the wearer's abdomen by the high heat-retaining region R1. Therefore, it becomes possible for the infant to settle down and sleep.

  The high heat retention area | region is arrange | positioned in the site | part which hits a wearer's buttocks in a waist part. Therefore, a wearer's buttocks can be warmed locally. The buttocks have a relatively large amount of blood flow, and can warm the trunk effectively by warming the buttocks. On the other hand, since the low heat retention area | region is provided, it can suppress heating the whole site | part covered with the disposable diaper excessively.

  Since the sheet material in the high heat retention region includes moisture-absorbing heat-generating fibers or far-infrared fibers, it is possible to increase the amount of heat generated at the portion that hits the sheet material. Since the high heat retention region R1 can be provided by the material of the sheet material that constitutes the exterior body, it can be easily configured as compared with a mode in which other members constituting the high heat retention region R1 are provided.

  In the disposable diaper, a first elastic sheet 71, a second elastic sheet 72, a front leg elastic member 81F, and a rear leg elastic member 81R as holding members are provided so as to overlap the high heat retaining region R1. Therefore, the high heat retention area | region R1 can be closely_contact | adhered to a wearer's body with the said holding member, and a wearer's abdomen and buttocks can be warmed locally.
