Have you ever worn a disposable diaper, used a filter, or gone shopping with reusable shopping bags? If so, you’ve likely interacted with spun bond nonwoven fabrics without even knowing it. Spun bond nonwovens are versatile materials widely used in a variety of applications ranging from hygiene and personal care products to industrial filtration and construction materials. In this blog post, we’ll take a deeper look at what spun bond nonwoven fabrics are, how they’re produced, their properties, and common uses.

Spun bond non woven fabrics are manufactured through a process known as spun bonding. In this process, continuous polymer filaments are as extruded through a spinneret and drawn out onto a conveyor belt. As the filaments extruded, they cooled and drawn out simultaneously by winders, quenching towers, and rollers. This draws and orientates the filaments into long strands. The filaments are then as deposited in a randomly distributed overlapping web-like structure on the conveyor belt through mechanical drawing. They are then as bonded together, either through hot air, chemical bonding, or ultrasonic bonding to form a coherent nonwoven fabric.

The key advantage of spun bond nonwovens over other nonwoven processes

Itlike meltblowing or needle punching is that the continuous filaments retain their individual identity even after bonding. This results in nonwovens that are stronger, with higher tensile strength and tear resistance compared to other nonwoven processes. Spun bond fabrics also have very low densities, are uniform in structure and thickness, and are highly permeable to gases and liquids. Some key properties of spun bond nonwovens include:

• High strength and tear resistance
• Uniformity of structure/thickness
• Low density
• Good abrasion resistance
• Permeability to gases and liquids
• Soft hand or feel similar to woven fabrics
• Can be as produced in wide widths on continuous production lines

A wide variety of polymers can be as used to produce spun bond nonwovens including polypropylene (PP), polyester (PET), polyethylene (PE), nylon, and biodegradable polymers like polylactic acid (PLA). However, polypropylene is by far the most commonly used polymer due to its good mechanical properties, chemical resistance, low cost and recyclability. The properties of the resulting spun bond fabric can be as varied by adjusting processing parameters like spinneret design, throughput rate, filament diameter, bonding methods and bond pattern.

Nonwoven fabrics are engineered fabrics made from synthetic fibers bonded together by chemical, mechanical, heat or solvent treatment. They are mainly used for filtration, hygiene products, medical applications, geotextiles and more. Meltblown nonwovens are a type of nonwoven fabric made by extruding thermoplastic fibers that are blown by high-velocity air onto a conveyor belt. The fibers bond and entangle as they land to form a fine, breathable fabric. Meltblowing is one of the most effective technologies for creating top-quality filters. This blog post will provide an overview of meltblown machine nonwoven fabric and its manufacturing process and applications.

How Meltblown Nonwovens Are Made?

Meltblown nonwovens are made through a specialized extrusion process called meltblowing. Polymer resins, usually polypropylene or polyethylene, are first melted and then extruded through tiny nozzles surrounded by high velocity hot air. As the hot air blows onto the molten polymers coming out of the nozzles, it stretches them into micro and nanofibers, allowing the fibers to get extremely thin in diameter, typically ranging from 1 to 10 microns. The fibers are then laid randomly onto a moving belt to form a nonwoven web. The entanglement of the ultrafine fibers as they land and bond to each other results in a very dense barrier fabric.

The meltblowing process allows control over final fabric properties such as fiber diameter, basis weight, and pore size based on factors like the polymer viscosity, air flow rate, distance between the nozzle and the collecting belt, as well as belt speed. This high level of control allows the creation of tailored nonwovens for specific applications. Meltblown fabrics are known for their barrier properties, fine fiber filtration efficiency, absorption characteristics and high surface area.

Key Components Of A Meltblown Machine

The main components of a meltblown machine include:

• Extruder: Melts the polymer resin and pumps it at a constant rate to the meltblowing die.
• Meltblowing die: Having rows of tiny holes called nozzles or capillaries that the molten polymer extrudes through. High velocity hot air blows onto the polymer streams exiting the nozzles and attenuates them into microfibers.
• Web forming chamber: Where the fiber streams are blown by the high velocity air onto a perforated rotating drum or conveyor belt moving in front of the die. The fibers accumulate on the belt into a meltblown web.
• Bonding method: Can be thermal point bonding with heated calender rolls or hydroentanglement jets that need pressure for fibers to entangle. Provides fabric strength.
• Winding system: Winds the consolidated meltblown fabric into rolls.

Advantages Of Meltblown Nonwovens

Some key advantages of meltblown nonwovens include:

• Very fine fiber diameters, down to submicron sizes. This gives a large surface area.
• High level of filtration efficiency. The microfibers intercept tiny particles and prevent them from passing through the fabric. Meltblowns can remove particles down to 2-3 microns and some even smaller.
• Breathable barrier properties, allowing gas and water vapors to permeate while providing a barrier for liquids. Useful for surgical gowns.
• Good absorbency due to the small interfiber spaces that can hold liquid. Often used as oil absorbents.
• Lightweight fabric with a soft draping handfeel. Does not irritate skin.
• Versatile, cost-effective and can be tailored to many different applications.
• Continuous production method makes high volumes possible.

Applications Of Meltblown Nonwovens

Some of the main uses of meltblown nonwovens are:

• Surgical face masks – Protect against infectious particles thanks to the excellent filtration ability of meltblowns. Most masks have a meltblown middle layer sandwiched between spunbond or other nonwovens providing strength.
• Air filters – Remove airborne particles from air streams in applications like vacuum cleaners, air conditioners and automotives. The submicron diameter fibers catch fine particles.
• Industrial workwear – Apparel like coveralls, gowns and sleeves used where hazardous particle protection is needed.
• Oil absorbents – Can soak up oils and hydrocarbon liquids from spills on land or water. The fabric’s oleophilic but hydrophobic nature is ideal for oil clean-up.
• Battery separators – Prevent direct contact between the anode and cathode in batteries while allowing ion transfer. The microporous structure provides electrical insulation.
• Wipes – For medical, industrial, cosmetic and other wipes where low-linting and softness are desired.
• Hygiene products – Used in diapers to provide a breathable, leakage barrier. Also in feminine hygiene items.

Nonwoven fabrics have become indispensable materials in a wide range of industries from hygiene and medical to construction and agriculture. One of the most versatile and commonly used nonwoven fabrics is spunbond polypropylene, known as PP spunbond. This material offers beneficial properties that make it a top choice for many applications. In this blog post, we’ll explore what exactly PP spunbond fabric is, how it’s produced, its performance properties, and the many uses for this nonwoven textile.

What Is Spunbond Polypropylene Fabric?

Spunbond polypropylene, or PP spunbond, is a nonwoven fabric made from polypropylene filaments. To produce it, polypropylene plastic pellets are first melted and extruded through tiny nozzles to form continuous filaments. As the filaments are extruded, they are rapidly stretched and elongated using high-velocity air jets. The filaments are then deposited on a moving belt in a random pattern to form a web. The web is thermally bonded using heat and pressure to fuse the overlapping filaments. This creates a strong, breathable fabric without any knitting or weaving.

The spunbond process results in a fabric with excellent strength, flexibility, and stability. Polypropylene itself is known for its durability, hydrophobicity, chemical resistance, and affordability. These attributes make PP spunbond a versatile material for many different applications.
