Under the title "Innovation Initiative Nonwovens" Groz-Beckert is mastering the challenges of a dynamic market, and consistently developing numerous conventional felting needles. The main focus here is on innovation - and the first solutions are due to be presented at the ITMA in Barcelona.
Market requirements with regard to needled and hydroentangled nonwovens are moving increasingly in the direction of
Furthermore, felting needles are expected to provide ever longer service
life, retaining constant needling performance and steadily reducing energy consumption
The same applies to jetstrips for hydroentanglement. Ideally the manufacturing speed for these products - i.e. the productivity - should not be adversely affected. Quite the reverse - it has to be increased still further!
Groz-Beckert is mastering this challenge. Development work is focusing on the efficiency of felting needles and jetstrips. On the basis of aspects such as coating, material, working part and needle geometry, the requirements mentioned are being fulfilled.
To achieve longer service life for needles, Groz-Beckert is working on needles with special coatings that may also result in reduced needling force. This coating also offers corrosion protection, and its anti-adhesive character reduces contamination.
On another new type of needle, by means of geometrical changes in the region of the working part, Groz-Beckert is achieving improved physical characteristics with lower penetration forces and improved surface aspects.
Similar properties that lengthen service life are achieved through the use of special materials. These contain extremely hard alloy components, so that the barbs of the needles are abraded far more slowly during use.
Special controlled heat treatment also contributes towards longer needling cycles and to even mechanical properties.
With the aid of a changed needle geometry - aimed at higher stability - Groz-Beckert achieves a sharp reduction in needle breakage, while the surface quality of the product requiring processing remains almost preserved.
The finest barbs and working part cross-sections with the highest evenness enable the use of Groz-Beckert felting needles even in product areas where ultrafine fibers, microfibers and also splittable fibres are used.A high degree of gentleness on fibres and base material, especially in the paper-machine felt sector, is achieved using working-part cross sections such as the teardrop needle. As the first result of the Innovation Initiative Nonwovens, the EcoStar - a universal needle for extreme requirements - will be presented at the ITMA in Barcelona.
Groz-Beckert is looking forward to providing you with stimulating new ideas for nonwovens at the ITMA in Barcelona. If you have any queries or suggestions at this point, please feel free to contact the experts from Groz-Beckert.
