Zetaloft+ the innovative and sustainable volume nonwoven

The topic of sustainability is becoming increasingly important in all branches of industry, and we at TENOWO are making a major contribution with our Zetaloft+ products. Zetaloft+ is a monopolymeric, voluminous and recyclable nonwoven with new properties for almost unlimited applications in a wide range of industrial segments.

Due to the special vertical fiber orientation and possible thermal-mechanical post-treatments, interesting additional functions of the final product can be achieved. On the one hand, Zetaloft+ can be recycled, and on the other hand, recycled fibers (e.g. from shredded PET bottles) can be used instead of virgin fibers to produce the volume nonwoven.

Benefits and characteristics

  • Recyclability: can be recycled in a single-variety textile composite
  • Breathable: very good air and moisture transportation
  • Memory effect: very good resilience
  • Sound insulation: good acoustic performance
  • Compressibility: compression hardness flexibly adjustable according to the desired application
  • Spacer material: core material for sandwich components in composite applications
  • Individual formability: individual three-dimensional formability by heat treatment
  • Laminable: can be laminated with various other materials
  • Thermal insulating: for heat and cold

Zetaloft+ and volume fleece in comparison


TENOWO's Zetaloft+: The pressure is distributed evenly over the fibers. The sinking object is surrounded by the lateral fiber layers.


Standard High Loft Nonwoven: The pressure acts at one point. Adjacent fiber layers are pressed down by the upper layers as well.

Applications by market segment


Applicable fibers

All cardable fibers mixed with at least 5% binder fibers can be used as fiber material. Natural fibers such as flax, kenaf, cotton and wool can also be processed with the addition of a suitable binder fiber.

Depending on the fibers used, very different properties of the volume nonwoven fabric can be achieved, depending on the application and the customer's wishes. A wide variety of fibers can be used on our lines to produce Zetaloft+ articles, including various natural fibers.

Technical details

Properties Value
Grammage On our lines we can produce basis weights between 100g/m² and 2000g/m².
Thickness Thicknesses from 10mm to 65mm can be produced without any problems.
Working width Widths up to 2300mm are possible.
Fiber material In principle, all cardable fibers can be processed with the addition of at least 5% of a "binder fiber". Natural fibers such as flax, kenaf, cotton and wool can also be processed with the addition of a suitable binder fiber.

Currently, our focus is on the processing of polyester fibers in blends with polyester binder fibers.

Miscellaneous If required, the volume nonwoven can also be laminated with cover materials, for example with another nonwoven, a woven fabric or even a knitted fabric.


Checking of compression hardness and nonwoven height

Definition and principle

The compression hardness test is a test technique related to the compression test for determining the compression hardness of foams. A square test specimen is compressed between two plates and the force required to compress this specimen to a certain amount of its original height (e.g. 40%) is measured. This value is then related to the tested area to give the compression hardness or compression resistance of the foam in kPa.


Compression hardness at 0 % compression


Compression hardness at 10 % compression


Compression hardness at 40 % compression


Compression hardness at 0 % compression (resetting capacity)

Technical data (example)

Next to the determination of the force required for the compression when a specific deformation is reached, it is also possible to plot a strength-strain diagram. In this case a characteristic compression hardness curve of the examined foam is obtained.

In general, this curve is nonlinear. Including the unloading process, the creation of a so called hysteresis loop is performed due to the delayed reverse deformation. The area of this loop is a measure of the elastic damping of the foam.

  • Pre-force 0.1 kPa
  • Tool distance 48.00 mm
  • Speed 300 mm/min
  • Height of nonwoven (sample) approx. 45 mm
  • CV40 = 7.30 kPa
