Spunbond nonwoven fabric for diaper

Spunbond nonwoven fabric is an essential material for producing high-quality disposable diapers. It is a non-woven fabric that is made from thermoplastic polymers, which are bonded together through the spinning process. This material is widely used in the diaper industry due to its excellent breathability, high strength, and softness. In this article, we will explore how spunbond nonwoven fabric is used in the production of disposable diapers.

1. Spunbond Nonwoven Fabric as a Top Sheet

The top sheet of a disposable diaper is the layer that comes into contact with the baby's skin. It needs to be soft, comfortable, and breathable to prevent rashes and irritation. Spunbond nonwoven fabric is an ideal material for the top sheet due to its excellent breathability and softness. The fabric is made by bonding together fine filaments of polypropylene, which creates a porous structure that allows air to circulate freely. This helps to keep the baby's skin dry and cool, preventing rashes and other skin irritations.

2. Spunbond Nonwoven Fabric as an Absorbent Core

The absorbent core is the most crucial part of a disposable diaper. It is responsible for absorbing and retaining the baby's urine and feces, preventing leaks and keeping the skin dry. Spunbond nonwoven fabric is used in the absorbent core of a diaper to provide strength, stability, and permeability. The fabric is combined with super-absorbent polymers and wood pulp to create an absorbent mat, which is then wrapped in a non-woven tissue to form the core. The spunbond nonwoven fabric provides structural support, ensuring that the core remains intact even when wet.

3. Spunbond Nonwoven Fabric as a Back Sheet

The back sheet of a disposable diaper is the layer that faces away from the baby's skin. It is designed to prevent leaks and provide a waterproof barrier, ensuring that the baby's clothes and bedding remain dry. Spunbond nonwoven fabric is an ideal material for the back sheet due to its excellent strength, permeability, and water resistance. The fabric is combined with a layer of polyethylene film, which provides the waterproofing properties. The resulting back sheet is strong, durable, and resistant to tearing, ensuring that the diaper remains intact even when wet.

In conclusion, spunbond nonwoven fabric is an essential material for producing high-quality disposable diapers. It is used as a top sheet to provide breathability and softness, an absorbent core to provide stability and permeability, and a back sheet to provide strength and water resistance. Without this versatile material, disposable diapers would not be as comfortable, efficient, or effective in keeping babies clean and dry.
