Groz-Beckert offers assisted product development and services for product and process optimization.

The true experts

Groz-Beckert provides the nonwovens industry with manufacturing solutions using any fiber material – whether wood fiber, animal fiber, natural fiber, mineral fiber or synthetic fiber. Therefore, unequaled application know-how concerning raw material but also carding and needling is what customers can expect. Groz-Beckert experts leading programs for assisted product development and product or process optimization come with well over 100 years of combined experience in all application segments. They are known as great in listening, smart in combining and innovative in thinking and they also give on-site training courses at the Groz-Beckert Academy – a highly valuable experience.

The Groz-Beckert Felting, Carding and TEZ experts take all efforts and determine the best approach for individual requirements together with the customer. The company’s own needle punch line is also ready – and offers many advantages!

Reliability as known from practice

Customer projects are run on machinery of leading manufacturers in the Technical Center Felting. State-of-the-art machinery featuring different variation options like pitches, condensing rollers, etc. can be booked as and if needed. A complete needle range with approx. thousand types is available to assure no limits when it comes to testing series.

The results are highly reliable due to industry-oriented working widths of all components of the production line. The experts lead through every single production step, and when it comes to the finishing of the produced textile surface, the equipment (padder, thermofixation unit with stretching and relaxing frame) is available to complete the job on a laboratory scale.

Groz-Beckert offers parallel tests in an accredited textile laboratory. On-site tests are always monitored by the customers who receive the complete test documentation after completion.

The place for tests and more

The versatile components of the production line and complementary services provide the basis for successful tests at the TEZ. Needless to say that the know-how customers gained will be treated confidentially. The TEZ was opened in 2010 in order to open up new development and application fields for textiles in cooperation with customers and partners. It’s meant to provide the perfect environment for bundling competences and knowledge. Customers agree.

Process-water analysis

The quality of process-water plays an essential role in the manufacture of spunlace products. The characteristics of the water, for example, affect the service life of different machine parts, as well as that of the jet strips.

Furthermore, process water not only greatly influences the quality of the end product in sanitary article production. It must be ensured that the water is hygienic.

As a leading manufacturer of jet strips, Groz-Beckert offers personal consultation in association with process-water analysis in order to create optimum prerequisites for efficient production.

Within a comprehensive laboratory analysis, Groz-Beckert will analyze your process water for important water-chemical parameters.


Impurities in process water leave traces in the nozzles. These are fiber rests, rust, metal particles, calcium deposits and chemicals added to the process water.

The resulting deposits inside the nozzles reduce the diameter and hinder water flow.

Impurities near the nozzle openings have an unfavorable effect on the formation of the water jets and thereby the water curtain. The physical properties of the spunlace products are consequently negatively affected. The jet strips must be professionally cleaned at regular intervals.

Groz-Beckert recommends applying a clearly defined cleaning process.

Practical knowledge applicable at any time

The Groz-Beckert Academy provides you with a comprehensive training program featuring hands-on practice with experienced trainers and the complete spectrum of the Technology and Development Center (TEZ).

In addition to basic, continuing and specialized training with a general focus – as well as for other textile production and joining procedures – one of the training programs specifically addresses the nonwovens industry.

In the course "Mechanical nonwoven fabric bonding" (course no. 130), you will learn the basics of needles and jet strips.
