AI Technical Summary
When baby girls wear diapers, the distance between the urethra and the anus is close, and the urethra is short, making them more susceptible to contamination by bacteria in feces, which increases the risk of urinary tract infections. Existing diaper designs are not ideal, leading to the mixing and spread of urine and fecal matter.
A highly soft baby diaper has been designed with an innovative structure consisting of a urine-absorbing layer, a feces-absorbing layer, and a barrier layer. The urine-absorbing layer and the feces-absorbing layer are respectively composed of a mixture of superabsorbent resin and fluff pulp. The diversion layer and the skin-friendly surface layer quickly absorb urine, and the barrier layer is separated by flexible silicone and a waterproof film to prevent fecal liquid from seeping forward.
It effectively reduces the risk of urinary tract infections, keeps the front of the baby's skin dry, reduces cross-contamination and skin irritation, and ensures comfort and hygiene.

Abstract
Description
Technical Field
[0001] This application relates to the field of diaper technology, and in particular to a highly soft baby diaper. Background Technology
[0002] Baby diapers are portable care products specifically designed for infants and toddlers. They are highly absorbent, breathable, and soft, effectively keeping baby's skin dry and preventing diaper rash. Diapers are typically made of soft non-woven fabric and highly absorbent materials, and feature elastic waistbands, leak-proof side panels, and moisture indicators to fit the baby's body shape, making diaper changes convenient for parents.
[0003] Currently, due to the unique physiological structure of female infants wearing diapers, their urethra is close to their anus, and their urethra is short, making them highly susceptible to contamination from bacteria in feces (especially E. coli). If the absorbent area of the diaper is not designed properly, when the baby defecates, the liquid in the feces may be spread to the front of the diaper by the absorbent material and come into contact with the urethra or other areas, significantly increasing the risk of urinary tract infections and other inflammations. Therefore, a highly soft baby diaper has been designed to address the aforementioned problems. Utility Model Content
[0004] To address this problem, this application provides a highly soft baby diaper.
[0005] The high-softness baby diaper provided in this application adopts the following technical solution:
[0006] A highly soft baby diaper includes a bottom layer, a urine-absorbing layer fixedly connected to the upper front end of the bottom layer, a feces-absorbing layer fixedly connected to the lower front end of the bottom layer, and an isolation layer provided between the urine-absorbing layer and the feces-absorbing layer;
[0007] The urine-absorbing layer includes a first absorbent core, which is fixedly installed on the bottom layer. A guide layer is fixedly connected to the front of the first absorbent core, and a first surface layer is fixedly connected to the front of the guide layer.
[0008] The fecal suction layer includes a second absorbent core, which is fixedly installed on the bottom layer, and the front part of the second absorbent core is fixedly connected to the second surface layer.
[0009] Preferably, the bottom layer is made of a breathable and waterproof TPU film, and both the first absorbent core and the second absorbent core are made of a mixture of superabsorbent resin and fluff pulp.
[0010] Preferably, the flow guiding layer is made of polypropylene limiting material, and the first surface layer is made of low-grammage polyester material.
[0011] Preferably, the second surface layer is made of coarse nonwoven fabric.
[0012] Preferably, the isolation layer consists of a waterproof layer and a silicone layer, with the silicone layer installed on the bottom layer.
[0013] Preferably, a waterproof layer is installed on the silicone layer, the waterproof layer being higher than the urine-absorbing layer and the feces-absorbing layer, and the waterproof layer being made of flexible polyethylene film material.
[0014] Preferably, the upper end of the bottom layer is fixedly connected to an elastic band, both sides of the elastic band are fixedly connected to hook and loop fasteners, the lower end of the bottom layer is fixedly connected to a connecting soft band, and the back of the connecting soft band is fitted with a hook and loop fastener textured surface adapted to the hook and loop fasteners.
[0015] In summary, this application includes the following beneficial technical effects:
[0016] This invention effectively solves the risk of urinary tract infections in female infants caused by the mixing of urine and feces in traditional diapers through innovative design of the urine-absorbing layer, feces-absorbing layer, and isolation layer. The urine-absorbing layer, made of a mixture of highly absorbent resin and fluff pulp, combined with a diversion layer and a skin-friendly surface layer, quickly absorbs urine and locks in moisture, keeping the front dry. The feces-absorbing layer utilizes coarse non-woven fabric and a highly absorbent core to specifically absorb moisture from feces, reducing the spread of contamination. The isolation layer, composed of flexible silicone and a waterproof film, physically separates the urine-absorbing layer from the feces-absorbing layer, preventing fecal leakage. The overall structure conforms to the baby's body, providing comfortable and breathable wear, reducing cross-contamination and skin irritation, significantly lowering the risk of urinary tract infections, while ensuring good practicality and hygiene.

Detailed Implementation
[0020] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0021] This application discloses a highly soft baby diaper. (See also...) Figure 1-2A highly soft baby diaper includes a bottom layer 1, a urine-absorbing layer 2 fixedly connected to the upper front end of the bottom layer 1, a feces-absorbing layer 3 fixedly connected to the lower front end of the bottom layer 1, and an isolation layer 4 provided between the urine-absorbing layer 2 and the feces-absorbing layer 3.
[0022] The urine-absorbing layer 2 includes a primary absorbent core 21, which is fixedly installed on the bottom layer 1. A diversion layer 22 is fixedly connected to the front of the primary absorbent core 21, and a primary surface layer 23 is fixedly connected to the front of the diversion layer 22. The diversion layer 22 is made of polypropylene limiting material, which quickly disperses urine into the lower absorbent core to avoid local accumulation and backflow. The primary surface layer 23 is made of low-weight polyester material to ensure comfort in contact with the baby's skin, while also quickly draining urine.
[0023] The fecal suction layer 3 includes a second absorbent core 31, which is fixedly installed on the bottom layer 1. The front part of the second absorbent core 31 is fixedly connected to the second surface layer 32, which is made of coarse non-woven fabric.
[0024] The bottom layer 1 is made of a breathable and waterproof TPU membrane to prevent liquid from leaking out while maintaining breathability. The first absorbent core 21 and the second absorbent core 31 are both made of a mixture of highly absorbent resin and fluff pulp, which have super water absorption and water-locking capabilities while remaining thin and light.
[0025] The isolation layer 4 consists of a waterproof layer 42 and a silicone layer 41. The silicone layer 41 is installed on the bottom layer 1. The waterproof layer 42 is installed on the silicone layer 41. The waterproof layer 42 is higher than the urine-absorbing layer 2 and the feces-absorbing layer 3. The waterproof layer 42 is made of flexible polyethylene film material. The silicone layer 41 is a medical silicone layer, such as food-grade silicone, to increase softness and elasticity.
[0026] The upper end of the bottom layer 1 is fixedly connected to an elastic band 5, and both sides of the elastic band 5 are fixedly connected to hook and loop fasteners 6.
