Spunlace nonwoven is a type of nonwoven fabric that is produced by entangling fibers using high-pressure water jets. This process creates a fabric with excellent softness, absorbency, and strength. Spunlace nonwovens are widely used in various applications, including wipes, medical textiles, hygiene products, and more.
Wood Pulp-Based Nonwovens:
Wood pulp-based nonwovens are materials that incorporate wood pulp fibers into nonwoven fabrics. Wood pulp fibers are known for their absorbency and biodegradability, making them suitable for applications where absorbent properties are essential. These nonwovens can be used in products like diapers, sanitary napkins, medical dressings, and cleaning wipes.
Physical Properties of Spunlace Nonwovens:
The physical properties of spunlace nonwovens, including wood pulp-based ones, can vary depending on factors such as fiber composition, production process parameters, and finishing treatments. Some common physical properties include:
Basis Weight: The weight of the fabric per unit area, typically measured in grams per square meter (gsm). It determines the thickness and density of the nonwoven.
Thickness: The distance between the two surfaces of the nonwoven material. It is usually measured in millimeters or micrometers.
Tensile Strength: The ability of the material to resist breaking when subjected to pulling forces. It is measured in force per unit width or area.
Absorbency: The capacity of the material to take up and hold fluids. Wood pulp fibers are known for their high absorbency.
Softness: The tactile comfort of the material. Spunlace nonwovens are often prized for their softness and gentle feel.
Bulkiness: The loft or thickness of the material, which affects its insulation properties.
Surface Texture: The texture of the material's surface, which can range from smooth to textured, depending on the manufacturing process.
Porosity and Air Permeability: The extent to which air and fluids can pass through the material. This property is important in applications like filtration.
Tear Resistance: The ability of the material to resist tearing forces.
Elasticity: The ability of the material to stretch and recover its original shape.
