Classification of Nonwoven Fabric

 In this age of virus and bacteria, who doesn't use wet wipes? It's handy, safe, and easy to dismiss.  It is commonly commercialized for babies' hygienic care. However, disposable wet wipes have spun its way to almost all of your cleaning essentials like adult makeup remover and household wipes disinfectant.


Admit it! It's very convenient to use and you can store it anywhere. Just pull out a sheet or two if you need to clean a speck of water or dirt, then toss it in the trash after use. These moist towelettes have features like that of a tissue paper and fabric cloth. The cloth-like material of wet wipes is from a spunlace nonwoven fabric.



What is Nonwoven Fabric?
Nonwoven fabric is a type of fabric material made from short and long fibers bonded together by chemical, mechanical, heat, or solvent treatment, not by weaving and knitting.  The textiles are synthetic polymer-based products that provide strength and versatility of fibers.
  
The largest manufacturers of nonwovens base on the region are North America, Europe, the Asia Pacific like China, Middle East & Africa, and South America.  And due to high medical needs, the global nonwoven market industry is projected to reach USD 49380 million by 2026, from USD 39480 million in 2020, at a CAGR of 3.8% during 2021-2026.

Classification of the nonwoven fabric is based on technology and production process:
•Spun-lace nonwoven fabric        
•Heat nonwoven fabric
•Pulp air-laid nonwoven fabric
•Wet nonwoven fabrics
•Spun-bond nonwoven fabrics
•Melt blown nonwoven fabrics
•Acupuncture nonwoven fabrics
•Stitching nonwoven fabric
 
People might not know about nonwovens, but consumer product is widely used in a variety of application and daily commodities such as:
• Apparel
• Automotive
• Construction
• Consumer products
• Electronics
• Filtration
• Furnishings/Bedding
• Geotextiles Product
• Hygiene
• Medical and Healthcare
• Packaging
 
Raw materials and manufacturing process
Raw materials in nonwoven fabric are Polyester (PET) & Polypropylene (PP), Viscose (Rayon in USA) & Tencel, wood pulp, and cotton. The most common fiber combination for spunlace in wet wipes applications is PET and Viscose.
 
Below are nonwoven manufacturing steps in forming a fibrous web, the technology of entangling or bonding the fibers in the web to impart mechanical integrity to the structure, and finishing/converting the fabric to impart some new and unique properties to the material specifies.
 
Web bonding
Needle punching is a process of bonding nonwoven web structures mechanically interlocking the fibers through the web. Barbed needles, mounted on a board, punch fibers into the web and then are withdrawn, leaving fibers entangled.
 
Stitch bonding is a consolidating fiber web with knitting components with or without yarn to interlock the fibers.
 
Thermal bonding is the process of using heat to bond or stabilize a web structure that consists of thermoplastic fiber.
 
Chemical bonding is the process of bonding a web employing a chemical and one of the most common bonding methods. The chemical binder is applied to the web and is cured.
 
Hydro entanglement is a process of using fluid forces to lock the fibers together.
 
Finishing and converting
Finishing and converting is the last operational contact performed on the fabric before it is delivered to the customer. After completing the material, it is usually cut to the width the customer specifies. We can offer big rolls and rolls for small packages.

The Development of Hydroentanglement (Spunlace) Nonwoven Fabric

Image
  lifekeepup.com                                                            Spunlace   is also known as hydroentanglement or hydro-jet. The jet spraying method uses high-speed and high-pressure water to impact the fiber web. This principle was developed by Dupont and Chicopee back in the late 1950s and early 1960s. It was a relatively new nonwoven processing technology in the 20th century.   Fiber, the product does not use adhesives, does not lint, does not shed, the product is hygroscopic, soft, high strength, and feels good.   Hydroentanglement Process Like the process principle of needle-punched,  spunlace nonwoven fabrics  use high-pressure water flow to form a "water needle," acting like acupuncture.   The web is fed into a r...
