VitaTex non-woven Polypropylene (PP) Spunbond, marketed as VitaSpun, is a durable, lightweight fabric used in industries such as agriculture, construction, automotive, medical, and more. Below we’ll explain how PP spunbond is made in our facilities and how this manufacturing process gives it its excellent properties.
The melted polypropylene is then forced through a metal plate, called a spinneret, that has hundreds of tiny little holes only fractions of a millimeter . . . .
What is Polypropylene??
crystalline thermoplastic
Polypropylene (PP) is a rigid crystalline thermoplastic made from propene (or propylene) monomer
Linear hydrocarbon resin
It is a linear hydrocarbon resin and is the lightest polymer among all commodity plastics.
Homopolymer / popolymer
Polypropylene is also available as either homopolymer or a copolymer both of which can be greatly boosted with additives.
How is Spunbond made?
Non-woven polypropylene (PP) spunbond is made by bonding hair-like filaments into a fabric sheet.
The process starts by feeding polypropylene pellets into the line and heating them until they melt to a soft toffee-like consistency. The melted polypropylene is then forced through a metal plate, called a spinneret, that has hundreds of tiny little holes only fractions of a millimeter in diameter machined into it to form long continuous hair-like strands called filaments. The filaments fall onto a moving belt which is the start of the formation process from pellet to fabric.
The freshly laid fibres then pass through a series of heated rollers which compress and bond the fibres together to form the final non-woven fabric.
Depending on the application of the finished spunbond fabrics additives may be mixed in at the start of the process or coatings applied to the fabric post-processing. These may allow for the fabrics to be softer, using a softening agent, more moister repellent or absorbent using hydrophobics or hydrophilics, or may have UV additives or coatings applied to maintain a better life span when left in the sun.
What are the characteristics of Spunbond?
Below are some of the key characteristics of nonwoven polypropylene spunbond:
Durable
Cost Effective
Thermal insulating
Non toxic
Recyclable
Lightweight
Breathable
Low electricity conductivity
What is Spunbond used for??
Spunbond has a vast range of uses because it can be manufactured in various colours and thicknesses, and because it blends so well with certain additives to make it fit for its required purpose.
When it comes to disposables, non-woven polypropylene spunbond is used in the manufacture of wipes, sanitary pads, diapers, disposable scrubs and hairnets, masks, carry bags etc.
Due to spunbonds durability, it is widely used in the production of household goods and home furnishing products like upholstery, mattresses and bases, curtains, table covers, chair covers, etc. In the retail space, spunbond fabric is used to manufacture high-quality reusable shopping bags.
Beyond the above spunbond fabric is used in the construction industry for under tile, providing waterproofing and thermal insulation to roofs in homes and commercial properties. In the agricultural sector, spunbond is used for weed control and crop cover to assist in the protection of crops against pests and frost.
There are very few industries that do not use spunbond in one way or another.
