Background
When an infant is walking, a baby care provider wears a paper diaper or a paper diaper to prevent the infant from uncontrollable defecation. It is not usually replaced until the diaper or diaper is filled with urine or the baby defecates. This is often a long time, sometimes longer, due to special circumstances or carelessness of the caregiver, to replace or remove the diaper which has been filled with the baby's feces. The skin of the baby covered by the diaper cannot be exposed to the air for a long time, and the baby can be injured, for example, the baby can be subjected to diaper rash and the like. Therefore, the diaper is always very important for nursing the buttocks of infants, and the diaper or the diaper worn by the infants when walking needs to have very good comfortableness, air permeability and the function of preventing bacteria from growing, and has the function of health care for the buttocks of the infants.
The paper diaper can be regarded as special clothes with a liquid absorption and control function. The absorption area mainly comprises a surface coating layer (a surface layer and a flow guide layer), an absorption core layer and a bottom film from inside to outside.
It is generally required that the diaper can rapidly absorb and store urine, which is mainly determined by the liquid water absorption and control capability of the absorbent core layer of the diaper, and a super absorbent resin is generally used, which has super absorbent capacity, is not easy to lose water even under pressure, and has good water absorption and water retention properties. The surface coating layer is a layer directly contacted with the skin of the infant, so that the surface coating layer is required to be soft in hand feeling, light, thin and comfortable, and skin-friendly without stimulation. The surface coating layer is the first layer of the paper diaper to realize functions, and has the function of transferring liquid to the absorption core layer in a single direction, and common materials comprise hot air bonded non-woven fabric, polypropylene short fiber, spunlace non-woven fabric and the like. The basement membrane is used for preventing urine from seeping out, plays a role in isolation, and is required to have good waterproofness and stretch-tearing resistance, and the main materials of the basement membrane comprise a PE (polyethylene) conforming basement membrane, a hot-rolled non-woven material, a pp (polypropylene) breathable microporous membrane and the like.
In the process of using the paper diaper. This balance is broken because the diaper cover blocks the release of heat and moisture from the skin to the outside, shielding the skin from ambient air currents. In such warm and humid microclimates, the presence of urine, and even bowel movements by the infant, causes an increase in bacterial content, humidity, temperature, etc., and causes skin blockage, a series of reactions, resulting in the development of a rash. Generally, after humidity is increased in a microclimate, the moisture increase rate of the epidermis of an infant is reduced, so that the stratum corneum of the skin is overhydrated, namely, after the cells absorb too much water, the cells swell and are loosely connected with each other, the pH value of the skin surface is increased, and under the stimulation of urine and dilution and a higher pH value environment, the activities of biological enzymes and microorganisms are increased, so that the barrier function of the skin is finally damaged, and the skin is more easily damaged in the case of mechanical movement and friction.
The prior art makes a great deal of research on infant paper diapers and paper diapers, and CN104706471A discloses a skin-friendly and skin-friendly health-care infant paper diaper and a preparation method thereof, wherein the skin-friendly and skin-friendly health-care infant paper diaper comprises a skin-friendly layer, an absorption layer and a waterproof bottom layer, the skin-friendly layer is formed by attaching a soft cotton layer to the surface of non-woven fabric, skin care liquid is permeated and absorbed in the soft cotton layer, and the skin care liquid is composed of the following raw materials which are prepared according to the weight ratio, 4-8% of centella asiatica extract, 4-10% of ilex purpurea Hassk extract, 2-4% of lithospermum extract, 7-15% of aloe gel freeze-dried powder and the. The invention claims that the infant's red buttocks', eczema and allergy have special curative effects.
CN103349592A discloses a diaper with good water absorption performance, which comprises a surface coating layer, an absorption core layer and a bottom lining layer, wherein the absorption core layer contains dried and dehydrated biological cellulose micro powder. The biological cellulose micropowder contains: glycerin, natural vitamin E, aloe juice, lily extract, honeysuckle extract, chamomile extract and towel gourd juice.
CN2600081Y discloses a health care type baby moxa bellyband panty-shape diapers, the bellyband panty-shape diapers comprise two parts, upper portion is the bellyband that is used for the baby to protect the tripe, the lower part is panty-shape diapers, can adopt direct-connected type or split type between the two parts, be provided with moxa layer or moxa fibre layer in the inlayer of bellyband panty-shape diapers, wherein, the crotch portion of direct-connected type panty-shape diapers is the movable connection of easy split, set up into multilayer structure with split type panty-shape diapers, its inlayer is the non-woven fabrics layer, be equipped with moxa layer or moxa fibre layer near the non-woven fabrics layer additional, the skin is powerful absorbent fibre water conservancy diversion layer and polymer wood pulp layer that absorbs water.
However, in the prior art, much attention is paid to improvement on prevention of skin allergy, inhibition of bacterial growth and the like, no attention is paid to change of pH value in the use process of infant diapers or diapers, actually, human urine has a wide pH value, the purpose is to maintain the pH value of blood in a normal range of 7.3-7.4, the kidney of a human body can produce urine with the pH value of 4.5-8.5, the pH value of the skin surface is increased along with the increase of ammonia content in microclimate in the diapers, and in a higher pH value environment, the activity of biological enzyme and microorganism is increased, so that the skin barrier function is finally damaged, and the west safety is more easily damaged in the case of mechanical movement and friction. Therefore, it is desirable to provide a diaper or diaper that can control pH, inhibit harmful microorganisms and irritant enzyme activity, and support skin barrier function.
