What is the difference between spunbond and spunlace?

Spunbond and spunlace are two different nonwoven fabric manufacturing processes that result in fabrics with distinct characteristics. Here are the main differences between spunbond and spunlace fabrics:

Manufacturing Process:

Spunbond: Spunbond fabric is produced by extruding continuous filaments of a polymer, such as polypropylene, directly onto a conveyor belt. These filaments are then bonded together by heat and pressure to form a fabric.

Spunlace: Spunlace fabric is made by entangling fibers of a variety of materials using high-pressure water jets. This process does not involve any chemical binders or adhesives.

Texture and Feel:

Spunbond: Spunbond fabrics are relatively stiff and have a smooth texture. They are often used in applications where strength and durability are important.

Spunlace: Spunlace fabrics are softer and more cloth-like in texture compared to spunbond fabrics. They are often used in applications where a soft feel is desired, such as in wipes and medical fabrics.

Strength and Durability:

Spunbond: Spunbond fabrics tend to be stronger and more durable than spunlace fabrics due to the way the fibers are bonded together during the manufacturing process.

Spunlace: Spunlace fabrics are softer and more drapeable but may be less strong and durable compared to spunbond fabrics.

Absorbency:

Spunbond: Spunbond fabrics are not very absorbent due to the way the fibers are arranged and bonded together.

Spunlace: Spunlace fabrics have higher absorbency levels because of the entangled fiber structure, making them suitable for applications where absorbency is important, such as wipes.

Applications:

Spunbond: Spunbond fabrics are commonly used in applications such as geotextiles, agriculture, hygiene products, and packaging.

Spunlace: Spunlace fabrics are often used in wipes, medical textiles, personal care products, and other applications where a soft feel and high absorbency are desired.

In summary, spunbond fabrics are known for their strength and durability, while spunlace fabrics are valued for their softness, absorbency, and textile-like feel. The choice between the two depends on the specific requirements of the intended application.
