The JEC Boston show was a very successful event that sparked many new applications discussions for Technical Embroidery. Booth attendees ranged from basic embroidery to extremely technical applications for Aircraft, Automotive and other very specialized fiber applications/processes.

Each discussion touched on several consistent comments from the attendees based on their respective manufacturing processes.

  • Automated Operations, minimal operator interaction required
  • Repetitive and repeatable embroidery
  • Broad range of application (on material or wire sizes)
  • Available in Single or Multi Head Platforms
  • Very Flexible embroidery patterns
  • Reasonably Priced

In addition numerous representatives from very well-known teaching institutions from the USA and Canada expressed interest in the basic and technical embroidery platforms that were demonstrated at the show. They commented that there is a renewed interest to offer classes for small or large scale commercial embroidery.

Technical Embroidery shown at the JEC 2012 by ZSK

Overall the JEC Boston Show demonstrated ZSK is a key machine manufacturer with a huge variety of platforms that can provide basic to specialized embroidery. Whether low or high volume needs, ZSK has the answer.

Technical Embroidery…


Embroidery machines place reinforcement fibres. Different textile technologies like spinning, weaving and knitting are well known and used to create fibre-reinforced composites for a fairly long time.


A radical new technology to build up reinforcement fabrics (preforms) is the free orientation, placing and fixing of reinforcement materials through an embroidery machine. The machines can be used in applications where the production of components or textile structures require the stitching of variable-geometry ply stacks, where fabrics need to be reinforced locally, or where fabrics must be assembled.

Various materials like carbon fibres, glass fibres, aramid fibres, wires etc. can be processed. Single layed rovings are fixed to the base material by stitching. During the process, the base material is moved by the embroidery machine's pantograph using numerical control, enabling to lay rovings in any direction and quantity.


The most significant advantage of producing fibre-reinforced composites using an embroidery machine is to lay the rovings according to the distribution of forces within a structural component. High reproducibility of the component's characteristics is another main aspect of this process. The roving layer's reproducibility is approx. 0,3 mm.
It is accomplished by the following factors:

  • automatic preform production
  • high dimensional accuracy
  • low mass tolerance and ever identical laying of rovings


The cost efficient process is driven by high stitching speed on one head and multiple working units on each machine to produce identical preforms.
In comparison to other textile technologies the expensive loss of materials like carbon or aramid fibres is very little. Accordingly the problem of waste disposal is minimal.


CAD embroidery software ensures that the machine control programme is designed to take required orientations for specific reinforcement fibres into account.
A large number of different patterns are used to stitch the fibre. Optional cutting and bending lines are also available, to be used in combination with a standard embroidering head for applying reference points.


Different technical devices like the automatic bobbin changer, the roll-to-roll device and the automatic roving cutter make it a highly productive system. A huge variety of machines and number of heads are available.

More and more companies see ZSKs new embroidery techniques as a process innovation to their technical and constructing challenges.
The automotive industry stitches copper wires for seat heating, aircraft design engineers experiment with laying their carbon fibre skins with ZSK special machines and the building industry is testing new methods of reinforcing concrete construction.
