Top Sheet Raw Material for Baby Diaper and Sanitary Napkin—non-woven fabrics
Non Woven Fabric or Non woven cloth is composed of directional or random fibers. It is a new generation of environmentally friendly materials.
The benefits of Non woven fabric include moisture-proof, breathable, flexible, light, non-burning, easy to decompose, non-toxic, non-irritating, rich in color, low in price, and recycled.
It is called non woven cloth because of its appearance and certain characteristics.
According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic and so on. Different ingredients bring distinct non-woven styles.
Why use non-woven fabrics as perforated air through top layer raw material for sanitary napkins and diapers?
Non-woven diapers are basically non-woven top sheets. Breathable non-woven fabrics can improve the air permeability inside the diaper. Steam can flow out of the diaper to discharge moisture and heat in time, effectively reducing the chance of diaper rash. It is soft and non-woven. It is comfortable and does not irritate the skin.
The layer of adult sanitary napkins is also non-woven fabric, but the non-woven diapers must be softer than sanitary napkins and more suitable for the baby's skin.
20.47% of users will pay great attention to the breathability of diapers when they buy baby diapers. The sweat glands of the baby's skin have very small sweat holes, and the skin temperature is not well controlled. For example, if the permeability of the diaper is not good when the heat and moisture collect on the diaper, easily baby will feel stuffy and further more diaper rash will be caused.
Due to the hot and humid environment in the diaper when urine is produced, from a professional point of view, the so-called breathability is actually water vapor permeability, which can be expressed by water vapor transmission rate (g/cm2·24h).
The bottom film, the outermost layer of the diaper, is usually the main factor for the breathability of the diaper, and it should be the skin-friendly layer. Because of the difference between water droplets (minimum diameter 20μm) and water vapor molecules (diameter 0.0004m), the nonwoven material used in the base film is waterproof and breathable.
The top sheet is the main raw diaper material of baby diapers, and it is also a very important part. It is in direct contact with the baby, so the comfort of the top sheet will also directly affect the baby.
Generally, the surface layer of a good diaper is hot air through nonwoven fabric, while spun-bonded non woven fabric is the mostly used in manufacturing medical industry.
It is understood that the baby diapers are heated and moisturized when they are worn. The microfiber hot-air non-woven fabric technology can play a better role in ventilation, and can effectively relieve the stuffy and humid environment of the baby's butt, greatly reducing the possibility of red butt, while feeling the basement membrane is softer, achieving better baby skin contact with zero friction.
