Baby Diaper is a diaper or nappy that allows the user to defecate without staining sheets or clothing without using a toilet. A dry diaper will keep the baby sleeping through the night. It is important to note that when the diaper becomes wet or dirty, it should be replaced in time.
Baby diapers are made from a combination of materials designed to provide absorption, comfort, and containment of waste. The specific materials can vary among different diaper brands.
Baby Diapers generally consist of three main parts: outer shell, absorbent core layer, inner layer, fastening tabs, elastic, and waistband and leg cuffs.
Polyethylene (PE) or Polypropylene (PP): The outer layer is typically made of a waterproof material, often polyethylene or polypropylene, to prevent leaks and keep moisture inside.
Nowadays, PE bottom film is rarely used, PE bottom film is not breathable, and now it is generally spunbonded non-woven bottom film more, which belongs to the mid-range configuration, the relative breathability and comfort of non-woven fabric, and the hot air bottom film is more high-end, which is softer and more breathable than the spunbonded non-woven bottom film.
The materials are generally included: Printing PE back sheet, Non-print PE back sheet, Cloth-like printing back sheet, Breathable cloth-like printing back sheet, Breathable air through cloth-like printing back sheet.

SAP (Super Absorbent Polymer): This is a key component of the absorbent core. SAP is a highly absorbent material that can hold many times its weight in liquid, helping to keep the baby dry.
Fluff Pulp: Derived from wood pulp, fluff pulp is another absorbent material used in diapers. It helps to distribute and hold the liquid.
Polypropylene or Polyethylene: The inner layer that comes into contact with the baby's skin is often made of a soft, non-woven material like polypropylene or polyethylene. This layer allows liquids to pass through to the absorbent core while keeping the baby's skin relatively dry.
These materials are generally included:
Spun-bonded non-woven fabric surface, Spun-bonded small pearl non-woven fabric surface, Air through non-woven fabric surface, Double layers pear no-woven fabric surface, Hot-rolled non-woven fabric Surface, Super soft and super white non-woven fabric surface.

Polyethylene or Polypropylene: The tabs that fasten the diaper around the baby's waist are typically made of a plastic material.
Polyurethane or Spandex: Elastic materials are used in the waistbands and leg cuffs to provide a snug fit. Polyurethane or spandex are common choices for elastic components.
Polypropylene or Polyethylene with Elastic Components: These parts are often reinforced with elastic materials to provide a secure and comfortable fit.
It's important to note that diaper manufacturers may use variations of these materials, and some may incorporate additional features such as wetness indicators, lotions, or fragrances.
Additionally, there has been an increasing trend in the development of eco-friendly diapers that use more sustainable materials and fewer chemicals.
