The primary function of the bottom layer in diapers is to prevent urine from leaking out. Initially, diapers mainly used PE film as the bottom layer. However, as consumers’ demand for comfort has increased, the emergence of a composite bottom layer made of nonwoven fabric and PE film has become prevalent. The softness of the bottom layer is one of the key criteria by which consumers judge the softness of diapers. Therefore, in addition to being leak-proof, having minimal fluffing, and being strong, the bottom layer made of nonwoven fabric should also have a fabric-like soft touch and be durable.
The breathability of diapers, primarily influenced by the bottom film or the outermost layer of the diaper, is a crucial factor. Babies have delicate skin and poor sweat evaporation. If the diaper is not breathable, after the urine is absorbed, heat and moisture accumulate inside the diaper, which can cause the baby to feel hot and potentially lead to redness, swelling, or inflammation of the buttocks, commonly referred to as diaper rash. As a result, more and more consumers pay special attention to the breathability of baby diapers, making it one of the important factors in their selection.
Currently, spunbond nonwoven fabric is the main material for the bottom layer in diapers due to its low cost, good wear resistance, and its soft, thin properties. Hot air nonwoven fabric, known for its softness and fluffiness, has been increasingly used in the bottom layer of many diaper products in recent years. However, hot air nonwoven fabric is made of short fibers and does not hold its shape as well as spunbond nonwoven fabric, and tends to fluff up a bit more. But in recent years, there have been significant improvements in hot air nonwoven fabric. Hence, countries like China, Japan, Korea, and those in Europe and America predominantly use dual hot air materials.
Recently, Yibero has released a new pull-up diaper with an excellent cost-performance ratio. Both the bottom layer and the surface layer are made of spunbond nonwoven fabric. The waistband also features a bubble waist design. With its innovative design and cost-effective materials, this pull-up diaper is particularly suitable for markets in Africa, the Middle East, and other countries along the Belt and Road Initiative, as these countries have lower consumer spending power, making high cost-performance products more marketable.
