Types Of Non-woven Fabrics

Non-woven fabrics are engineered materials made from fibers or filaments that are bonded together through mechanical, chemical, thermal, or solvent means rather than being woven together like traditional textiles. These fabrics have a wide range of applications due to their versatility, strength, and cost-effectiveness. Here are some common types of non-woven fabrics:

  1. Spunbond Non-wovens: These are made by extruding melted polymer fibers onto a conveyor where they are bonded by cooling. Spunbond non-wovens are strong and durable, often used in applications requiring high tensile strength, such as disposable medical gowns and drapes, as well as agricultural covers.
  2. Meltblown Non-wovens: Meltblown fabrics are produced by melting polymer granules and extruding them through tiny nozzles. The fibers are then blown by hot air onto a conveyor, creating a fine web of fibers. Meltblown fabrics are known for their filtration properties and are used in face masks, air filters, and oil sorbents.
  3. Needle-punched Non-wovens: These fabrics are created by mechanically entangling fibers using barbed needles. Needle-punched non-wovens are used in applications requiring strength and durability, such as automotive interior linings, carpet backing, and geotextiles for construction.
  4. Wet-laid Non-wovens: In wet-laid non-woven manufacturing, fibers are suspended in water, and a binder is added to form a fibrous mat. After water is removed, the material is bonded. These fabrics are used in specialty applications like battery separators and food packaging.
  5. Spunlace Non-wovens: Spunlace fabrics are made by mechanically entangling fibers using high-pressure water jets. They are soft and highly absorbent, making them suitable for applications like baby wipes, cleaning wipes, and medical dressings.
  6. Thermal-bonded Non-wovens: These fabrics are bonded together using heat. They are commonly used in disposable tablecloths, napkins, and dryer sheets.
  7. Airlaid Non-wovens: Airlaid non-wovens are produced by combining pulp fibers with air and a binder. They are used in absorbent products such as feminine hygiene products and disposable diapers.
  8. Composite Non-wovens: These are multi-layer non-woven fabrics that combine different types of non-woven materials or combine non-wovens with other materials like films or foams. They are used in products like surgical gowns with liquid-resistant barriers.
  9. Biodegradable Non-wovens: With increasing environmental concerns, some non-woven fabrics are designed to be biodegradable or made from natural fibers like cotton or bamboo to reduce their environmental impact.

Each type of non-woven fabric has unique properties and characteristics that make it suitable for specific applications. They offer advantages such as cost-effectiveness, versatility, and ease of manufacture, making them essential in a wide range of industries, including healthcare, agriculture, automotive, construction, and consumer goods.
