The exclusive equipment of our pilot plants and laboratories, coupled with the specialised expertise and vast experience of our employees, permit a high degree of process monitoring of our production operations. We achieve steady quality assurance and improvement thanks to consistent control and testing procedures.

Our research centres stand for visions, realising ideas from the first inspiration through to industrial implementation and are synonymous with unique performance in relation to customized solutions.

The equipment in our pilot plants

As a diversified manufacturer of nonwovens from a variety of fibersor fiber blends through carding, we have a very wide range of reinforcement options available to us. Laboratory cards are used to evaluate suitable fiber materials.
Thanks to sophisticated equipping of the carding machines, there are no limits to the modifications we can make to the production systems.

In recent years, TENOWO has invested in two pilot plants with this purpose in mind: on the one hand, in a pilot plant for the processing of recycled carbon fibers into nonwovens at the Hof location, and on the other hand in a pilot plant for stitch-bonded nonwovens at our location in Mittweida.

 

 

Pilot plant Hof

Rohstoffe_600x600px

The carbon pilot plant created in 2010 at our Hof location is constantly being extended and includes two nonwoven systems.
A laboratory system with an operating width of 80 cm offers a way to test a variety of fiber types and quantities.
There is also a pilot plant for nonwovens in use for near-series production. Carbon and hybrid nonwovens with mechanical needle or stitch-bonded reinforcement are produced there in operating widths of up to 200 cm.

Pilot plant Mittweida

TENOWO-Technikum-Mittweida_600x600px

Built in 2020, the unique pilot plant in Mittweida offers a wide range of possibilities for production of a variety of stitch-bonded nonwovens.

In addition to solo units of Maliwatt, the plant also features inline operation of fiber blending, fiber preparation, crosslapping and mechanical reinforcement.

Our laboratory equipment

For quality checks of our products and for the development of special formulations for use in finishing nonwovens, e.g. with flame retardants or to make them oil-, water- and diesel-repellent, we can formulate the textile auxiliaries at laboratory scale and then finish, print and coat the nonwovens with these functional agents.
