Embodiment 1

[0027] In this embodiment, the functional powder layer 32 in the heating element 3 in the disposable absorbent article is a mixture of iron powder, activated carbon powder, vermiculite powder, deionized water, water-absorbing resin, and sodium chloride. Among them, the content of iron powder is 56wt%, activated carbon powder 12wt%, vermiculite powder 12wt%, deionized water 18wt%, water absorbent resin 1wt%, sodium chloride 1wt%.

[0028] The principle of the reaction is oxygen absorption corrosion between iron powder and oxygen in the air and deionized water (or distilled water). Negative electrode: Fe-2e - → Fe 2+ ; Positive pole: O 2 +2H 2 O+4e - →4OH - . Total reaction: (1), 2Fe+O 2 +2H 2 O→2Fe(OH) 2 ;(2), 4Fe(OH) 2 +2H 2 O+O 2 →4Fe(OH) 3 ↓; (3), 2Fe(OH) 3 → Fe2O3 + 3H2O; after balancing the equations (1), (2), (3), the equations are: (4), 4Fe+3O 2 →2 Fe 2 o 3 . The enthalpy variable calculated by equation (4) is △H=-3296.8KJ<0, that is, the reaction bet...

Embodiment 2

[0035]In this embodiment, the functional powder layer 32 in the heating element 3 of the disposable absorbent article is a mixture of iron powder, activated carbon powder, vermiculite powder, deionized water / distilled water, water-absorbing resin, and sodium chloride. In the powder layer, the content of iron powder is 56wt%, activated carbon powder 12wt%, vermiculite powder 12wt%, deionized water 18wt%, water absorbent resin 1wt%, sodium chloride 1wt%.

[0036] According to the test method of the warm palace heating element 3 of the present invention, the test results of the warm palace heating element 3 of this embodiment are as follows: the heating time at 40°C is 25min (minutes), the duration at 40°C is 1h (hour), and the duration at 35°C is 11h (hours), the highest temperature is 40°C, and the average temperature is 40°C. In this embodiment, increasing the amount of water will slow down the heating rate, lower the heating temperature, and prolong the heating time.

Embodiment 3

[0038] In this embodiment, the functional powder layer in the warm palace heating element 3 in the disposable absorbent article is a mixture of iron powder, activated carbon powder, vermiculite powder, deionized water / distilled water, water-absorbent resin, and sodium chloride. In the layer, the content of iron powder is 50wt%, activated carbon powder 12wt%, vermiculite powder 20wt%, deionized water 16wt%, water absorbent resin 1wt%, sodium chloride 1wt%.

[0039] According to the test method of the heating element 3 of the present invention, the test results of the heating element 3 of this embodiment are as follows: the heating time at 40°C is 10 minutes (minutes), the duration at 40°C is 4 hours (hours), and the duration at 35°C is 7h (hours), the highest temperature is 52.8°C, and the average temperature is 46.4°C. The proportion of iron powder and water remains unchanged, but the proportion of vermiculite increases, the maximum temperature increases, the heating speed is ...

Abstract

The invention relates to a disposable absorbing article comprising an absorbing body, an outer cover layer and a uterus warming heating body. The outer cover layer is jointed to one side, away from an absorbing core, of a liquid-tight bottom layer of the absorbing body. The absorbing article is provided with a front waist area, a rear waist area and a crotch area, the front and rear waist areas are hermetically jointed together at the relative transverse side edges to form a side edge seal portion to form a waist opening and a pair of leg openings, the uterus warming heating body is jointed to one side, away from the skin of a wearer, of an outer cover piece of the front waist area, the uterus warming heating body is provided with a heating body and an oxygen insulation film cover layer, the heating body is provided with an oxygen insulation film cover layer, a functional powder layer and a breathable nonwoven fabric layer, one side of the breathable nonwoven fabric layer is covered with the oxygen insulation film cover layer, and the periphery of the oxygen insulation film cover layer is jointed to the periphery of the heating body of the uterus warming heating body.

Description

technical field [0001] The invention relates to a disposable absorbent article used by women during menstruation, in particular to a disposable absorbent article capable of alleviating women's menstrual dysmenorrhea. Background technique [0002] In the field of disposable absorbent articles, especially those for women's menstrual use, typically comprise a liquid-permeable topsheet material, a liquid-impermeable backsheet material, and an absorbent layer positioned between the topsheet material and the backsheet material. Disposable absorbent articles are generally used to absorb and contain the wearer's excrement such as menstrual blood, urine and other excrements. The absorbent layer is used to collect and store the excrement of the wearer. The absorbent layer usually includes a fiber batt or fiber web composed of thermoplastic fibers, separated wood pulp fibers, and loose and fluffed hydrophilic cellulose fibers. Microparticles, granules, flakes or fibers of superabsorbe...
