Nonwoven fabrics have become an essential part of our daily lives, from the surgical masks we wear to protect ourselves from COVID-19 to the filters in our air purifiers. These fabrics are versatile, durable, and easy to manufacture. One of the critical components in the production of nonwoven fabrics is the meltblown machine, which converts thermoplastic materials into meltblown fibers.

With the proper equipment, meltblown nonwoven machinery can produce consistent fabrics for a variety of filters, barrier materials, medical & hygiene products and more.

The Key Machine Types Used For Meltblown Nonwoven Fabric Production Are:

• Extruders:
  Polymer resin is melted and extruded through tiny spinneret dies containing several hundred tiny holes to produce many molten polymer threads simultaneously.
• Airblowing Systems:
  High-velocity hot air is blown against the extruded polymer threads, which attenuates and draws the threads into fine fibers between 5 and 15 micrometers in diameter. This blown air also deposits the fibers in a random fashion onto a conveyor belt.
• Conveyor Systems:
  The conveyor belt below the fiber-forming zone collects the randomly deposited meltblown fibers and moves them forward for further processing.
• Bonder Units:
  The loose nonwoven web passes between heated calendar rolls that bond fiber intersections to give the fabric integrity and strength. Additional web treatments may also be applied.
• Winder:
  The finished meltblown nonwoven web is wound into large rolls for storage, transport and further converting.

The core machine types used for spunbond nonwoven fabric production are:

Spinneret Extruders:

Polymer resin is melted and extruded through fine holes called spinnerets to form continuous filaments. The spinnerets can have thousands of holes to produce many filaments simultaneously in a curtain or ribbon-like fashion.

Drawing Ovens:

The extruded filaments pass through heated draw air systems that cool and elongate the filaments, making them thinner and more uniform. This stretching increases the strength and mechanical properties of the filaments.

Laydown Head:

The drawn filaments are deposited onto a movable belt using a laydown head that controls filament density and geometry. The filaments land in a random orientation, becoming the nonwoven web.

Bonded Area Calenders:

The loose nonwoven web passes through heated calenders to bond the filaments at crossover points. This entanglement holds the web together and gives the fabric strength and integrity.

Winder And Rolls:

The finished nonwoven fabric web is wound onto large rolls for storage, transport, and further processing. Secondary finishing operations like water-jet needling may also be performed.

Spunbond nonwoven fabric make machine precisely controls filament formation, laydown, bonding, and winding to produce strong, uniform nonwoven webs ideal for fabrics, wipes, geotextiles, and medical gowns and drapes. Modern spunbond lines feature advanced technologies for higher throughput, consistent web properties, and reduced energy usage.

Nonwoven fabrics have a diverse range of applications and properties, making them one of the most versatile textile products. Nonwoven fabrics are manufactured using various nonwoven production processes that convert different fiber types into webs and fabrics. These production machines are key to nonwoven fabric manufacturing. Let’s review an overview of the nonwoven production machines and processes that enable the creation of nonwoven fabrics.

Key 4 Steps In Manufacturing Non woven Fabrics

There are several key steps and machines involved in manufacturing nonwoven fabrics:

1. Fiber processing: Fiberizers and cutters break down fibers into staple form for use as raw material. Cards and garnetts parallelize and align the fibers.
2. Web formation: Various processes form the nonwoven web. A card webber uses parallelized fibers in a layered web. An airlay machine deposits fibers using circulating air. Spunbond and meltblown machines produce continuous filaments to form the web.
3. Web bonding: Nonwoven machines like needlepunchers, thermal and chemical binder units consolidate the web using mechanical, heat, or chemical means for strength.
4. Finishing: Calenders and other nonwoven machines apply finishing treatments to enhance properties such as permeability, absorbency, and appearance.

The Main Types Of Non woven Fabric Machines

There are four main types of machines used in the production of nonwoven fabrics:

1. Fiber Preparation Equipment
   Equipment like fiberizers, cutters, cards and garnetts prepare fibers to become the raw material for nonwoven fabrics. They break down fibers into staple form and align and parallelize the fibers.
2. Web Formation Machines
   These machines form the nonwoven web. A card webber uses parallelized fibers to form a layered web. Airlay machines deposit fibers using circulating air. Spunbond and meltblown machines produce continuous filaments to create the web.
3. Web Bonding Machines
   Needlepunchers, thermal and chemical binder units consolidate the nonwoven web using mechanical, heat or chemical means, adding strength to the fabric.
4. Finishing Machines
   Calenders and other finishing machines apply treatments to the nonwoven web to enhance properties like permeability, absorbency and appearance.

PP (polypropylene) spunbond nonwoven fabric is widely used in applications like wipes, hygiene products, filtration media and geotextiles due to its strength, absorbency and breathability. PP spunbond machines manufacture this nonwoven fabric through a process that “spins” PP filaments and then bonds them using heat, needle punching or adhesive. Here are details on how these machines work and their features:

What Is a PP Spunbond Fabric Making Machine?

A PP spunbond fabric making machine uses melted PP pellets as input material. The molten PP is extruded through small spinnerets into many fine filaments. As the filaments exit the spinnerets, a flow of hot air attenuates and draws them out to desired fineness. The filaments are then deposited in a random fashion onto a collector belt to form a web.

The nonwoven web is then passed through a bonding process to fuse the PP filaments together. This can be done using:

• Thermal bonding – Hot air knives or infrared radiation bonds the filaments by heatsoftening the PP.
• Mechanical bonding – Needle punching entangles the filaments to achieve bonding.
• Chemical bonding – Adhesives are sprayed onto the web to bind the filaments.

The bonded nonwoven web is wound onto a reel and then heat set to stabilize its properties. The end result is a continuous roll of PP spunbond nonwoven fabric.

Key Components of PP Spunbond Lines

The main parts of a PP spunbond line include:

• Extruder – Melts and pumps the PP to the spinnerets.
• Spinnerets – Contains thousands of tiny holes that extrude the filaments.
• Air supply – Blows air jets to draw and attenuate the filaments.
• Conveyor belt – Collects the randomly deposited filaments to form a nonwoven web.
• Thermal/mechanical/chemical bonding unit – Fuses the web’s filaments.
• Post-treatment unit – Includes winding, slitting and heat setting equipment.

Manufacturers offer PP spunbond making machines with different line widths, production speeds, numbers of spinnerets and bonding types to produce a range of nonwoven properties for different applications.

Features to Consider PP Spunbond Fabric Making Machine

When selecting a PP spunbond fabric making machine, factors to evaluate include:

• Line speed – Higher speeds provide greater output but require more sophisticated components.
• Line width – Wider lines produce larger nonwoven widths in a single pass.
• Filament fineness – Finer filaments yield softer, smoother fabrics at lower basis weights.
• Throughput – The machine’s rate of transforming PP pellets into a nonwoven fabric roll.
• Uniformity – Even filament deposition and bonding yield consistent nonwoven properties.
• Operating efficiency – Factors like energy consumption, waste generation and uptime.
• Material options – Some lines can process recycled PP and other polymers.

Melt blown fabric machines produce nonwoven materials made of very fine fibers formed through a process known as meltblowing. The melt blown fiber formation process, combined with properties like high surface area and small pore size, make these nonwovens suitable for a variety of applications.

What Are Melt Blown Fabric Machines?

Melt blown fabric machine – also called melt blowing systems or meltblown lines – consist of several main components:

• Extruder – Melts and pumps polymer resins like polypropylene or polyethylene.
• Die assembly – Contains spinnerets or nozzles that extrude the molten polymer.
• Compressed air system – Generates high-velocity air jets that draw out the extruding fibers.
• Conveyor belt – Collects the extruded fibers to form a nonwoven web.
• Heat and quench section – Solidifies the meltblown fibers.
• Post-treatment unit – Includes options for web bonding, slitting and winding.

In operation, molten polymer is extruded through the nozzles while high-speed air jets draw and attenuate the extruding polymer into very fine fibers. The randomly dispersed meltblown fibers are deposited onto a moving conveyor belt, which draws the web at the same rate fibers are being formed.

The web then passes through a heat and quench section that solidifies the fine fiber structure. Post-treatment options bond, consolidate and wind the nonwoven web to produce a useable meltblown fabric.

How Meltblown Fibers Are Formed？

The key aspect of melt blowing is the high-velocity air that exits the die in jets alongside the extruding polymer. As polymer emerges from the nozzles:

• The air stretches and attenuates the nascent fibers very rapidly.
• The fibers are drawn out to fine diameters of 1 micron or less within 20 cm of the die.
• The fiber trajectories become randomized, dispersing fibers uniformly across the web.

The high-temperature air also helps cool and solidify the fibers immediately after formation, stabilizing their thin structure before fibers can recombine.

Features Of Melt Blown Fabric Machines

• Die dimensions – Nozzle width, shape and spacing.
• Air flow – Temperature, pressure and jet velocity.
• Polymer throughputs – How quickly the line converts resin into fabric.
• Web characteristics – Basis weight, thickness, fiber diameter and pore size.
• Line widths – The maximum nonwoven fabric width produced in a single pass.
• Processing capabilities – What polymer types the machine is optimized for.

Manufacturers offer machines with different configurations, throughputs and heating/cooling systems to produce nonwoven webs with varied properties for specific end uses.

Meltblown nonwoven fabric is used for various products like face masks, wipes, filters and insulation due to its very fine fiber structure and high surface area. Meltblown machines transform polymer resins into nonwoven webs through a process that “blasts” thin fibers onto a collector. Here are details on how these machines work:

What is A Meltblown Machine?

A meltblown machine uses extrusion and high-velocity air to produce nonwoven webs of meltblown fibers. The main components of the machine are:

• Extruder – Melts and pumps the polymer resin to the die assembly.
• Die Assembly – Contains multiple tiny nozzles or melt channels that extrude the molten polymer.
• Hot Air Supply – Blows high-temperature air across the exit of the nozzles.
• Conveyor Belt – Collects the extruded fibers to form a nonwoven web.
• Post-Treatment Unit – Includes web drawing, cooling, bonding and winding equipment.

In operation, the molten polymer is extruded through the die nozzles while high-temperature air flows across the nozzle exits. The airstream “blasts” and attenuates the extruding polymer into very fine fibers (0.5 – 50 μm).

The randomly dispersed meltblown fibers are then deposited onto the moving conveyor belt, which draws the web at the same rate that fibers are being laid down. As the web passes through the post-treatment unit, it is bonded, cooled and wound onto a reel.

How Meltblown Fibers Are Formed

The key to meltblown fiber formation is the high-velocity air that exits the die along with the extruding polymer. As the molten resin emerges from the nozzles, the airstream:

• Stretches the extruding polymer filaments very rapidly.
• Attenuates the filaments into fine fibers within 0.2 to 2cm of the die exit.
• Randomizes the fiber trajectories, causing them to distribute uniformly across the web.

The high air temperatures also help quench and solidify the meltblown fibers almost immediately after formation. This “traps” their fine fiber structure before fibers can recombine.

Features Of Meltblown Machines

Meltblown machines are characterized by:

• Die geometry – Slot, circular or rectangular nozzles with varying dimensions.
• Air flow – Air temperature, pressure and velocity.
• Throughput rate – How fast the machine converts resin into nonwoven fabric.
• Web characteristics – Basis weight, thickness, fiber diameter and pore size.
• Line width – The maximum nonwoven web width the machine can produce.
• Processing capacities – What polymer types the machine is optimized to process.

Manufacturers offer meltblown machines with different configurations, throughputs, and heating/cooling systems to produce a wide range of nonwoven web properties for various end uses.
