non woven fabric waterproof

This comprehensive guide explores the world of non woven fabric waterproof materials, covering their types, applications, benefits, and considerations for selection. We'll delve into the properties that make them waterproof, examine different waterproofing techniques, and offer practical advice for choosing the best option for your specific needs.

Types of Waterproof Non Woven Fabrics

Spunbond Non Woven Fabrics

Spunbond non woven fabric waterproof materials are created by bonding continuous filaments together. Their strength and durability make them suitable for applications requiring high tensile strength. Waterproofing is often achieved through lamination with a film or coating. Examples include those used in disposable medical garments or industrial applications requiring robust protection. The level of waterproofness can vary significantly depending on the chosen coating or lamination process.

Meltblown Non Woven Fabrics

Meltblown non woven fabric waterproof fabrics are produced by extruding molten polymer through tiny nozzles. This creates a highly porous structure, often used as a filtration layer in applications like face masks. When combined with other non-woven layers, or treated with a waterproof coating, meltblown fabrics can offer effective waterproofing. They are known for their softness and absorbency, making them a good choice for certain applications, but they may not offer the same durability as spunbond fabrics.

SMS Non Woven Fabrics

SMS fabrics (Spunbond-Meltblown-Spunbond) combine the benefits of both spunbond and meltblown layers. A meltblown layer is sandwiched between two spunbond layers, resulting in a material that is both strong and has good filtration properties. This makes SMS fabrics a versatile choice for applications requiring both strength and waterproofness, such as disposable wipes or hygiene products. The spunbond layers provide strength, while the meltblown layer aids in the barrier properties, which can be enhanced by additional waterproofing treatments.

Waterproofing Techniques for Non Woven Fabrics

Several techniques are used to achieve waterproofness in non woven fabrics:

• Coating: Applying a polymer coating, such as polyurethane or polyethylene, creates a waterproof barrier.
• Lamination: Bonding a waterproof film, such as polyethylene film, to the fabric provides excellent waterproofing.
• Treatment: Chemical treatments can alter the fabric's surface properties, making it more resistant to water penetration.

Choosing the Right Waterproof Non Woven Fabric

Selecting the right non woven fabric waterproof material depends on several factors:

• Intended Application: The intended use dictates the required level of waterproofness, strength, and breathability.
• Durability: Consider the level of wear and tear the material will endure.
• Cost: Different types of non woven fabrics and waterproofing techniques have varying costs.
• Environmental Considerations: Choose eco-friendly materials and processes whenever possible. Recycled or biodegradable options are becoming increasingly available.
