Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically to a diaper with good absorbency. Background Technology

[0002] Disposable diapers are a type of disposable hygiene product. Their core function is to absorb and lock in human urine and feces, keeping the skin dry. They are widely suitable for infants and incontinent individuals. Their core advantages are "convenience of use + leak prevention and skin protection," making them a replacement for traditional cloth diapers.

[0003] Currently, the amount of urine that ordinary disposable diapers can absorb is relatively fixed, so they need to be changed after one or two uses. When used at night, if the baby urinates frequently at night, the diaper may not be able to absorb it completely. In this case, the unabsorbed urine will come into direct contact with the baby's skin, which may lead to skin allergies and other problems, affecting the baby's sleep at night. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This utility model provides a technical solution: Referring to 1-3, in this embodiment, a diaper with good absorption effect includes: a wrapping cloth 1, which is made of SMS spunbond-meltblown-spunbond composite nonwoven fabric, which has both breathability and tensile strength; and a composite absorbent cloth 2, which is fixedly disposed on the wrapping cloth 1. The composite absorbent cloth 2 is a hot-air nonwoven fabric and is in contact with the baby's skin; and a plurality of separator cloths 3, which are evenly distributed inside the composite absorbent cloth 2. The separator cloths 3 are made of hydrophilic nonwoven fabric and divide the absorption area into multiple independent cavities. Absorbent through-hole 4 is formed through the bonding surface of the composite absorbent cloth 2; waterproof sleeve 5 is inserted into the absorbent through-hole 4. The waterproof sleeve 5 is a tubular structure made of PE film with a hydrophilic coating on the inner wall. The hydrophilic coating is polyethylene glycol modified acrylate, which guides the urine to flow downward and avoids side leakage, ensuring that the urine is delivered to the bottom absorbent material 8. The waterproof sleeve 5 penetrates several separator cloths 3; absorbent material 8 is filled inside the composite absorbent cloth 2. The absorbent material 8 is a mixture of superabsorbent polymer and fluff pulp. The absorbent material 8 is located between the composite absorbent cloth 2 and the separator cloths 3; return flow hole 7 is formed through the separator cloth 3 and is evenly distributed in the middle of the separator cloth 3 to ensure that the urine flows smoothly to the upper layer after the bottom layer is saturated.

[0017] It also includes: several support strips 9, which are fixedly set on the composite absorbent fabric 2. The surface of the support strips 9 is in contact with the skin. The support strips 9 are made of elastomer material. The support strips 9 are made of TPU elastomer with a semi-circular cross section. They are set parallel to the width direction of the composite absorbent fabric 2. The support strips 9 are fixed to the surface of the composite absorbent fabric 2 by hot melt adhesive. They can support the gap between the surface and the skin, improve breathability, and reduce moisture adhesion.

[0018] It also includes: elastic fabric 12, which is fixedly set at both ends of the wrapping fabric 1; wrapping strap 13, which is fixedly set on both sides of the elastic fabric 12. The elastic fabric 12 is made of spandex core-spun yarn non-woven fabric to ensure that the waistband fits the baby's waist without leaving marks; the wrapping strap 13 is made of spunbond non-woven fabric with rounded edges to avoid scratching the skin.

[0019] It also includes: a sub-hook and loop fastener 14, which is fixedly set on one side of two of the packing straps 13; and a female hook and loop fastener 15, which is fixedly set on the remaining packing straps 13. The sub-hook and loop fastener 14 is a hook and loop fastener, and the female hook and loop fastener 15 is a loop fastener. Both are made of PP material and are fixed to the packing straps 13 by ultrasonic heat pressing process to ensure that they are not easy to fall off after being pasted.

[0020] It also includes: a wrapping sheet 10, which is fixedly installed on both sides of the wrapping cloth 1. The wrapping sheet 10 is a composite non-woven fabric with folded edges on the inner side. It is fixed to the wrapping cloth 1 with hot melt adhesive and can wrap the baby's groin area to reduce the risk of urine leakage.

[0021] It also includes: a leak-proof band 11, which is fixedly installed on the wrapping cloth 1. The leak-proof band 11 is located on both sides of the composite absorbent cloth 2. The leak-proof band 11 is in contact with the skin. The leak-proof band 11 has a double-layer structure. The inner layer is a hydrophilic non-woven fabric, which has the characteristics of fast water absorption, efficient conduction and high water absorption ratio. It can quickly absorb the urine in contact and prevent side leakage. The outer layer is an elastic spandex fabric, which has the characteristics of high elasticity, high resilience and soft skin-friendly, which can improve comfort. The bottom is fixed to the wrapping cloth 1 by hot melt adhesive, and the top is a free edge, which naturally fits the groin. The leak-proof band 11 has high elasticity and will not produce obvious marks when stretched. At the same time, it can block side leakage of urine and further improve the leak-proof effect.

[0022] It also includes: absorbent cotton 6, which is filled inside the waterproof sleeve 5. The absorbent cotton 6 is made of high-loft degreased cotton. The bottom end of the absorbent cotton 6 is in contact with the absorbent material 8. After the absorbent cotton 6 comes into contact with urine, it will absorb the urine and quickly conduct it to the bottom absorbent material 8, avoiding urine from remaining on the composite absorbent cloth 2 for a long time and improving comfort. The absorption effect of the absorbent cotton 6 is less than that of the absorbent material 8, which ensures that the urine absorbed by the absorbent cotton 6 can be quickly absorbed by the absorbent material 8.

[0023] This invention provides a diaper with good absorbency, and its working principle is as follows: When using, unfold the diaper and, with the elastic fabric 12 and wrapping strap 13, attach the wrapping fabric 1 to the baby's waist. Secure it with the hook and loop fasteners 14 and 15, adjusting to the appropriate tightness. The wrapping sheet 10 and leak-proof strap 11 are then attached to the baby's groin and sides, respectively, providing all-around leak protection. When the baby urinates, the urine first contacts the surface of the composite absorbent fabric 2, quickly seeping into the waterproof sleeve 5 through the absorbent holes 4. The absorbent cotton 6 absorbs some of the urine and guides it towards the bottom absorbent material 8. The bottom absorbent material 8 quickly absorbs and expands, locking in moisture. Once the bottom absorbent material 8 is saturated, subsequent urine flows upwards through the return flow holes 7 on the separator fabric 3 to the unsaturated absorbent material 8, achieving layered absorption. Simultaneously, the support strip 9 supports the surface of the composite absorbent fabric 2, maintaining a gap between it and the baby's skin to promote air circulation and prevent direct contact between the saturated absorbent material 8 and the skin, keeping the skin dry. Even with frequent nighttime urination, this reduces the risk of skin allergies and improves the baby's sleep quality.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
