Services – solving problems and making new discoveries

The capability of always being able to apply the right tool and accessories is fundamental in the manufacture of nonwovens.

To contribute to the success of our customers, Groz-Beckert not only provides all necessary products from a single source, but also services which give safety.

The staple fiber needle punch line and textile testing

At the Competence Center Felting Technology a staple fiber needle punch line is available to you in various utilization options for tests and joint projects in both needle and textile development:

  1. Use of the entire line
    From fiber bales to main needling, all line components (fiber opening, nonwoven card, crosslapper, web drafter, pre- and main needling) can be employed.

  1. Use of the line beginning with the feeding point of the web drafter
    In order to test tensile strength, for example, in this option the (pre-) nonwoven is fed from the web drafter, before then reaching the needling zones.

  1. Use of the line beginning with the feeding point of the pre-needling
    After feeding in a slightly pre-needled fabric, it can undergo pre- and main needling.

  1. Use of main needling
    This option contains needling tests on the DI-LOOM OUG-II SB 15 with pre-bonded nonwovens.

In addition to the use of the line, Groz-Beckert offers production-specific testing:

  1. Density
  2. Thickness
  3. Fabric weight
  4. Air permeability
  5. Tensile strength
  6. Web profile

Competent professionals in application engineering work out solutions to problems and support you in developing your products. Textile testing and measuring devices also play an important role in the assessment of nonwovens and form the basis for comprehensive service. Specifically, Groz-Beckert assists you with:

  1. Dynamic penetration-force measuring
  2. Textile analysis (fiber/product)
  3. Needle analysis
  4. Baseline investigations
  5. Product assessments (surface, rigidity, density, ...)

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.

Cleaning

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.
