Spunbond Nonwoven Geotextiles


What is the difference between spunbonded and needlepunched nonwoven geotextiles?

Needle punched nonwoven fabrics are made from blended webs of continuous or staple filaments that are passed through banks of multiple reciprocating barbed needles. The fabrics derive mechanical coherence from the entangling of fibres caused by the barbs on the reciprocating needles; these fabrics thus resemble wool felts. Spunbond fabrics are produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers. The fibers are separated during the web laying process by air jets or electrostatic charges. Bonding imparts strength and integrity to the web by applying heated rolls or hot needles to partially melt the polymer and fuse the fibers together.

What is the advantage to using a spunbond geotextile?

The main advantage offered by spunbonded nonwoven geotextiles is higher tensile strength per unit of mass (weight) when compared to a needlepunched nonwoven. However, you do sacrifice a little of the flow rate.

Are your products Typar?

No. Typar is a brand name manufacturer of nonwoven spunbond geotextiles. US Fabrics offers our own line of nonwoven spunbonded geotextiles. You can check the Product Equivalent box at the top of the page to compare our products with Typar.

Spunbond Nonwoven Geotextiles

US Fabrics offers a line of spunbond, nonwoven geotextiles in addition to our needle punched, nonwoven geotextiles. Spunbonding is one of the most popular methods of producing nonwoven fabrics. The first spunbonded, polypropylene fabrics were introduced in the 1960's. Considerable advances in the technology have been made since its initial introduction. Spunbond fabrics are used in the carpet, furniture, medical and geotextile industries.

The most successful manufacturer of these products is Typar®. As a result, all manufacturer's spunbond products are often referred to as "Typar" as a group. US Fabrics SF line of spunbond geotextiles are offered as equivalents to the Typar® product line.

  • Quality Spunbonded Nonwovens
  • Superior Tensile Strength Per Weight
  • Uniform Weights and Properties
  • Equals to Typar®

The spunbond process is considered the fastest manufacturing method for nonwoven fabrics. As a result, spunbonding is considered to be more economical than other manufacturing methods such as needle punching staple fiber. During the spunbonding process extruded filaments are spun onto a collecting belt and bonded by applying heated rolls.

US Fabrics SF line of geotextiles are nonwoven, spunbonded, continuous filament, polypropylene geotextiles that offer the consistent quality expected of spunbond geotextiles.
