Introduction to Non-Woven Fabrics
Non-woven fabric is composed of oriented or randomly arranged fibers and is recognized as a new generation of environmentally friendly materials. It is known for its moisture resistance, breathability, flexibility, lightweight structure, non-combustibility, easy decomposition, non-toxicity, non-irritation, rich colors, low cost, and recyclability.
Often made from polypropylene (PP) pellets, non-woven fabrics are produced through a continuous one-step process involving high-temperature melting, spinning, laying, and hot-pressing before winding. Though not woven like traditional textiles, these fabrics have the appearance and functional qualities of cloth. This versatility makes them suitable for various industries, including hygiene products and wet wipes packaging film, where material performance directly influences final product quality.
Main Production Processes of Non-Woven Fabrics
Spunbond
Spunbond is one of the most widely used non-woven production methods. Polyester, polypropylene, or other polymer chips are melted and extruded through a screw extruder. High-speed hot air stretches the melt stream from the spinneret, cooling and solidifying it rapidly to form fibers. These fibers are laid randomly on a mesh to create a web, which is then consolidated by hot rolling or needle punching.
Spunbond non-woven fabrics are known for their high strength and firm texture, making them ideal for disposable surgical gowns, protective clothing, and geotextiles. Their durability also supports the structural integrity of wet wipes packaging film, where strength and resistance to tearing are essential.
Meltblown
In the meltblown process, polymer melt is extruded from a spinneret and stretched by high-speed hot air to produce ultrafine fibers. These fibers condense in the air, forming a web that bonds either by self-adhesion or thermal bonding. Meltblown nonwovens are prized for their filtration efficiency and thermal insulation properties, commonly used in mask filters and thermal lining materials.
Spunlace (Hydroentanglement)
Spunlace uses high-pressure water jets to entangle fibers, producing a non-woven fabric that is soft and highly absorbent. This method yields materials ideal for hygiene applications such as wet wipes, facial masks, and medical gauze. The softness and absorbency of spunlace nonwovens make them a preferred choice for products housed in wet wipes packaging film, ensuring a comfortable and effective user experience.
Thermal-Bonded
Thermal-bonded nonwovens are made by heating the fiber web until fibers melt together, either using their melting point or with the help of adhesives. The result is a fabric with excellent strength, often used in insulation and filling materials.
Needle-Punched
In the needle-punched process, a carded fiber web is repeatedly pierced with barbed needles, mechanically entangling the fibers to create a durable non-woven fabric. Known for its high abrasion resistance, needle-punched fabric is widely used in carpets, filter media, and geotextiles.
Wetlaid
Wetlaid production involves dispersing fibers into a liquid to form a slurry, which is then deposited into a web and dried. This process can incorporate both natural and synthetic fibers, offering versatility in applications from specialty papers to technical non-woven products.
Choosing the Right Non-Woven for Wet Wipes
The choice between spunlace, airlaid, and other non-woven types depends on factors such as absorbency, softness, durability, and compatibility with wet wipes packaging film. For instance:
- Spunlace is favored for softness and skin comfort.
- Airlaid offers high absorbency and bulk for heavy-duty wipes.
- Spunbond provides durability for packaging or wipe reinforcement.
