About this product

SWM netting can help you save material and improve product performance.


There are different methods to incorporate SWM netting with other substrates and materials. Our netting can be used with film, foam, bubble wrap, paper, nonwoven and other fabrics. The following processes show how SWM netting can be used in various manufacturing processes.

 


HOW TO USE SWM NETTING IN PRODUCTION PROCESSES


1. EXTRUSION COATING / LAMINATION


A polymer film can be extruded directly onto the substrate to provide a bonding layer (extrusion lamination) or an impervious coating (extrusion coating). SWM plastic netting can be trapped between the substrate layer and the extruded film layer to significantly increase the tensile strength of the final product.

 

 

2. LAMINATION


A laminate is a material that can be constructed by uniting two or more layers of material. The various layers that make the laminate can be similar or different materials: plastic netting, plastic films, nonwovens, paper, etc.

 

 

3. ADHESIVE LAMINATION


Unless one of the fabrics develops adhesive properties in certain conditions, an additional medium is necessary to secure the bonding between the layers. Two adhesive lamination techniques are illustrated below.

 

 

3. NONWOVEN PROCESSES


Nonwovens consist of millions of individual fibers. In a first manufacturing step, the nonwoven is produced via drylaid, wetlaid, spunbond or meltblown processes. SWM plastic netting can be incorporated in this first step called “web formation.”


WEB FORMATION It is the stage where individual fibers or molten polymers are laid to form a nonwoven web that will eventually be bonded for additional integrity, strength and stability.

 

BONDING

After the web formation step, the fibers and the plastic netting are bonded together to form the final nonwoven composite. SWM can customize the plastic netting design and configuration to meet the properties and performance required in the final nonwoven product. There are different processes available to bond various types of nonwovens. We illustrate some of the most common processes:

THERMAL LAMINATION

One of the two materials of the laminate is melted to the other material under increased temperature and pressure to secure a good bond.

ULTRASONIC WELDING

Similar polymers can be combined using mechanical vibration and pressure. The substrates are threaded through a wellprecised gap where high frequency vibration and pressure generate heat to weld the layers together.

WET LAMINATION

A solvent or emulsion adhesive is applied to the netting or the nonwoven, putting both materials together under pressure and letting the solvent evaporate.

DRY LAMINATION

Powders (e.g. E.V.A.), plastisols or hot melt adhesives are applied to one of the substrates via several coating techniques: roll coating, spray coating, die coating, and laminated together under pressure.

AIRLAID PROCESS

Drylaid nonwovens can be carded or airlaid. Airlaid is a technology to convert fibers into fabric nonwovens. Fibers are introduced into an air stream and form a web of randomly distributed fibers.

WETLAID PROCESS

This technology also uses fibers to form fabric nonwovens. It is a process similar to papermaking where a water/fiber mixture is released onto a forming belt. The excess water is removed to generate a fiber and pulp web.

SPUNBOND OR MELTBLOWN PROCESS

These two technologies use polymers to form fabric (meltspinning) nonwovens. Meltblown differs from spunbond by its finer filaments and softer materials.

CHEMICAL BONDING

A bond is established between the fibers of the web using a bonding agent.

THERMAL BONDING

The criss-crossed fibers of the web are welded together into a firm nonwoven by passing them through hot rotating cylinders.

MECHANICAL BONDING

Strengthening of the web is achieved by the inter-fiber friction as a result of the physical entanglement of the fibers. There are two major types of mechanical bonding: needlepunch and spunlace (or hydro-entanglement).
