Diapers are essential products for modern childcare and special populations (such as incontinence patients, post-surgical patients, and people with mobility issues). Diaper topsheet is a crucial component of diapers as it directly contacts the baby’s skin. The choice of topsheet material directly affects the user’s experience.

The primary materials for modern diaper topsheets are Hot Air Nonwoven Fabric and Spunbond Nonwoven Fabric. So, which material provides a better experience for diaper users?

1. Manufacturing Process

Hot Air Nonwoven Fabric is produced by melting fiber materials at high temperatures and then bonding them together through a hot air system. This process creates a porous structure with excellent breathability and softness.

2. Characteristics

  • Softness: Hot Air Nonwoven Fabric is extremely soft, effectively reducing friction between the diaper and the baby’s skin, enhancing wearing comfort.
  • Breathability: Its porous structure provides good breathability, quickly expelling moisture and keeping the diaper interior dry.
  • Absorbency: This material also has excellent absorbency, quickly absorbing and locking in urine, preventing rewetting.
  • Eco-friendliness: Hot Air Nonwoven Fabric is typically made from environmentally friendly materials that contain no harmful chemicals, making it non-irritating to the baby’s skin.

3. Applications

Hot Air Nonwoven Fabric is widely used in high-end diaper products, especially suitable for babies and individuals with sensitive skin who require high softness and breathability.

Spunbond Nonwoven Fabric

1. Manufacturing Process

Spunbond Nonwoven Fabric is made by melting polymer chips at high temperatures and extruding them into continuous filaments, which are then bonded into fabric through mechanical embossing or thermal bonding. This process gives Spunbond Nonwoven Fabric high strength and durability.

2. Characteristics

  • Strength: Spunbond Nonwoven Fabric has high mechanical strength and abrasion resistance, able to withstand significant tension and friction without breaking.
  • Stability: This material maintains good stability when wet, resisting deformation or breakage.
  • Cost-effectiveness: Compared to Hot Air Nonwoven Fabric, Spunbond Nonwoven Fabric has lower production costs, making it more economical.
  • Water Resistance: Spunbond Nonwoven Fabric has some water resistance, effectively preventing external liquids from penetrating the diaper.

3. Applications

Spunbond Nonwoven Fabric is widely used in mid- to low-end diaper products, suitable for consumers who prioritize durability and cost control.

Comprehensive Comparison

Both Hot Air Nonwoven Fabric and Spunbond Nonwoven Fabric have their advantages and disadvantages. Hot Air Nonwoven Fabric excels in comfort, breathability, and absorbency, making it a preferred choice for parents seeking high comfort and breathability. In contrast, Spunbond Nonwoven Fabric is known for its strength and durability, better suited for active babies with less sensitive skin.

When choosing diapers, parents should consider the baby’s specific conditions and needs. If the baby has sensitive skin and prioritizes tactile sensation and breathability, it is recommended to choose diapers with a Hot Air Nonwoven Fabric topsheet. For babies with less sensitive skin who are more active, diapers with a Spunbond Nonwoven Fabric topsheet may be more suitable, ensuring flexibility and a snug fit without leakage.

Additionally, parents can distinguish between topsheet materials by touching and gently pulling them. Diapers with a Hot Air Nonwoven Fabric topsheet feel soft and comfortable, easily pulling out fibers. In contrast, Spunbond Nonwoven Fabric feels harder and is difficult to pull out in whole pieces. By using these simple identification methods, parents can more accurately choose diapers that suit their babies.
