One of the closing system part of diapers---side tape It is very important for whether it is easy for parents and babies to put on and take off the diaper, whether the baby wears diapers to affect the activity. The diaper is designed with side tape in order to make it easy for infants to wear the diaper, and to open or re-wear the diaper after inspection. Side tape is many small and even hooks (hook side)on one side, and a lot of pile loops on the other side (loop side). The distribution of small hooks and pile loops on the side tape is even. The two straps are aligned and gently squeezed to create a adhesive force. Side tape is used for wearing, connecting or opening diapers. It has the advantages of convenient inspection and quick recovery, and the Side tape can be used repeatedly. Good Side tape is made of specialized PP(polypropylene) raw material, it has no adverse effect on the infant's skin. There are three main types of diapers: zigzag diapers, waist stick diapers and pants diapers. Waist sticker diapers have side tape on both sides of the diaper, the design is three-dimensional, can wrap the baby's butt. Most of the diapers on the market are waist stick diapers. The waist stick diaper ensures that the diaper fits the baby's waist better, and will not shift, loosen or fall off even if the baby changes the body position. Good quality diapers, the side tape can be used many times, constantly adjusted to the appropriate size, so that the diaper will not loose or tight will not cause side leakage. Like Sinbao diapers, with good viscosity of the side tape, and designed with a soft elastic waist. It can make the baby feel comfortable and natural, but also can enhance leak proof. If the baby's mother uses a care product such as oil, powder or body wash, these care products may touch the adhesive position and reduce its adhesion. Therefore, when wear diapers, try to ensure that the hands are dry and clean, according to the baby's waist, put the buckle(side tape ) on both sides , aligned with the waist stick part and then stick well.
Read MoreDiapers’ three-dimensional leg cuffs----anti-leakage leg cuff Another important part of the diaper is the three-dimensional leg cuff. The main materials of leg cuff are non-woven fabric, spandex (also known as lycra, which is a kind of elastic fiber) and hot melt adhesive. The leg cuff is put the spandex warp between two layers of non-woven fabric and use hot melt adhesive to adhesive them together. Spandex is safe in diapers, which are wrapped in non-woven material that does not come into direct contact with your baby's skin. The three-dimensional leg cuff is also called the anti-leakage leg cuff, which is the frilly that stands up on the inner thigh. It can make the diaper close to the baby's thigh and effectively prevent the waste from leaking out along the gap between the thigh and the diaper. Because the leg cuff is soft and elastic, it can not only prevent leakage and reduces rashes, but also match your baby's flexible movement. At present, most diapers on the market contain 2 layers of spandex. In the case of the same elasticity and tightness, the baby wearing only 1 layer of spandex diaper will feel tight on the thigh. But using two layers of spandex will give you the desired effect: leak-proof and don’t feel tight. When the size of the diaper is too large, the spandex is not stretched or stretched too little, resulting in the leg cuff can not be closely wrapped around the baby's butt, which is prone to urine leakage. When the size is too small, the spandex is stretched too much, the baby may feel tight on the thigh and waist and it may cause rashes due to the friction and not breathable. Suggestions for Xinbao diapers: 1. Choose diapers suitable for your baby's body according to his/her weight, waist and height. Different brands may define the size differently, so be sure to look at the size when shopping. 2. When putting on the diaper, help the leg cuff of the pleated part of the diaper with your fingers to make it stand up, so as to effectively prevent leakage. 3. After wearing diapers, mothers had better use their hands to rub a circle along the root of the baby's thighs to ensure that the frill is not folded inward and stuck on the baby's legs, so as not to affect the leak-proof effect. 4. Buy regular products to prevent the baby from allergies, or diapers are not breathable and other problems. To observe more, it proved the diapers is too big if the diapers are very loose when the baby crawling and walking.
Read MoreBack sheet ---the water resistant outer layer of diapers Marion O’Brien Donovan, She was one of the most prolific female inventors of her time and she had received 20 patents in total for her inventions. Donovan was inducted into the National Inventors Hall of Fame in 2015. In the past, infant after used cloth diapers, which could easily cause diaper rash. Marion Donovan, a mother, took the plunge and cut a shower curtain into pieces, then used buttons instead of pins to create a waterproof diaper cover. At first the manufacturers were not interested in her invention, but she did not give up and continued to work hard on her invention. Eventually she received funding for her product and began manufacturing and selling it, which soon became a huge hit. Donovan’s invention leak-proof waterproof diapers that changed sanitary products forever. The back sheet is the water-resistant outer layer of the diaper. It can prevent liquids from passing through the diaper and leaking into the baby’s clothes or surrounding environment. The main raw material of the back sheet is polyethylene film(PE film) also called permeable micro-porous film and composite bottom film. The bottom film looks like a plastic film, actually it's a breathable micro-pore film. The micro-pore is the most critical part, because the minimum diameter of a water drop is 20µm, and the diameter of a water vapor molecule is 0.0004µm. The micro-pore diameter is in between those two diameters. In this way, it is breathable and impermeable to water. Sinbao back sheet PE film is one kind of hydrophobic film. It allows water vapor and air (but not liquids) to pass through, it’s with good air permeability and would keep baby skin dry and comfortable.
Read MoreThe details of one of baby diaper’s raw material ---ADL ADL is the abbreviation of Acquisition Distribution Layer. ADL is the second layer of the diaper and it’s the non-woven material between the top sheet and the absorbent core layer. ADL creates low-density voids under the surface layer. The function is to accelerate the penetration and diffusion of liquid into the absorbent core layer (fluff pulp+SAP) and reduce the liquid infiltration. The ADL layer can ensure the uniform distribution of liquid, so that it is not easy to breakage, clumping, deformation, and reduce the contact between urine and the skin. The progress of the penetration and diffusion of liquid: When the liquid comes to the top sheet, it’s absorbed by the top sheet. And penetrate into the ADL. Under the action of pressure and gravity, the liquid is diverted into the absorption core for storage, preventing contact between the liquid and the skin, and reducing leakage of the liquid. It provides a dry and comfortable environment for the baby. Baby’s skin health has improved because these polymers lock moisture away where it cannot irritate skin. The severity and frequency of diaper rash has declined dramatically. In the early days, spun-bond non-woven or perforated membranes were mainly used as ADL, but in recent years, breathable bonded non-woven are mainly used as ADL. To improve the visual effect, the ADL has different colors.
Read MoreMedical non-woven fabric Medical non-woven fabric is used in the labor ward scrub, surgical sheet, table cover, isolation gown, surgical cap, shoe cover, bedding, sterilizing wrap, wound care product and others. Surgical sheet and surgical gown are the largest portion of non-woven fabric in the medical field, accounting for more than 50% of non-woven consumption. Non-woven fabric continue to be favored by the medical industry because non-woven products are generally superior to textile products in terms of the property of comfort, barrier and pollution resistance. With the COVID-19 pandemic sweeping the world in 2020, the demand for personal protective equipment (PPE) has soared, which undoubtedly testifies to the value of non-woven fabrics. Looking ahead, the increasing aging of the global population, infection prevention and the prevalence of chronic diseases will be some of the major growth for the medical non-woven fabric market. Sinbao hydrophilic non-woven fabric, hydrophobic non-woven fabric and spunlace non-woven fabric,.etc. will met your meet in some way, please feel free to contact us.
Read MoreOne of diaper’s main part---top sheet Diapers contain many parts, one of it is top sheet which has a close contact with the baby’s or adult’s skin. The top sheet is soft and it allows the liquid flow to the ADL layer and pass through quickly into the absorbent core. The common raw material of top sheet is Polypropylene. And Polypropylene is made from plastic resins. The top sheet of diaper is hot-air non-woven sheet or spunlace non-woven sheet after Polypropylene goes through the mechanically, chemically, or thermally bonded. Sinbao’s top sheet can be divided into two sheets: hydrophilic non-woven sheet and hydrophobic non-woven sheet. The part of hydrophilic sheet is SSS(spunlace-spunlace-spunlace)layer normally, because it has close connection with baby’s and adult’s skin so it’s soft and the function of it is to transfer the liquid to the absorbent core. The part of hydrophobic sheet is the leakage part of the crotch and the leg cuffs. Due to the material of the top sheet, it can protect the skin from over hydration and reduce irritation.
