Vitrulan woven rovings made from glass or carbon, coating carriers and filtration fabrics as well as other products for special applications.


Production options

When it comes to the production of technical fabrics, the possibilities are almost endless. Whether woven rovings made of glass or carbon, technical fabrics as coating carrier or for filtration, the production options are vast:

• Traditional mesh structures with leno weave technique or as drebfabric (DORNIER EasyLeno®-2T)
• Compact and closely woven fabrics with air-jet or rapier weaving machines
• Warp beam weaving and creel feeding possible

Woven rovings (glass)
Woven rovings made of glass are compact constructions with a high material weight for applications that require particularly high strength and low deformability.For best compatibility with the resin systems employed in the composites, roving materials with different sizings are used.

Woven rovings (carbon)
Woven rovings made of carbon offer outstanding technical properties and low grammage, which enables a wide range of applications in the field of component parts made of fiber-reinforced composites.Carbon is chemically inert and thus highly resistant to most acids, alkalis and solvents, and absorbs virtually no water.

Woven fabric tapes
Thanks to special tape weaving machines, it is possible to manufacture fabric tapes in the required width with a stable selvedge.In addition, reinforced extra wide fabrics can be cut lengthwise with widths varying subject to customer requirements.

Coating carriers
Fabrics woven from glass fiber or synthetic yarns are used in a variety of ways in the coating industry.The specific material properties of the coating carriers mean that the technical parameters of the coated membranes, such as maximum tensile strength or elongation and shrinkage behavior, can be tailored perfectly to the intended application.

Filtration fabrics
Filtration fabrics made of glass or synthetic materials for solid/liquid separation, hot gas or particle filtration.The materials are selected for the different fabric constructions in line with the desired filtration effect and resistance.A wide range of filtration fabrics can be produced – from open supporting fabrics used in the production of needle-punched fleece for hot gas filtration to highly dense fabrics for solid/liquid separation.

Knitted fabrics consist of parallel courses of threads that are joined to each other by interlocking loops. This enables the production of high elastic and tear resistant textile fabrics.

The warp and weft threads of our weft-knit fabrics can be made of glass fiber or polyester yarn, whereas the binding threads are always made of polyester yarn.

The resulting open mesh structures are reinforced with various binder systems on a direct finishing line.

Due to their high tear and tensile strength, knitted fabrics made of glass fibers are ideal as reinforcement mesh for marble and natural stone slabs or for use in knitted fabrics/fleece laminates. The latter are used for laminating insulation materials such as rock or glass wool.

Polyester knitted fabrics offer additional elasticity that enables them to adapt perfectly to the forces they are subjected to, making them ideal for use in roofing and waterproofing membranes.

Laminates combine the superior technical properties of different products. Lamination with a woven fabric, for example, significantly increases the perforation and puncture resistance, which is usually only achieved with tightly woven fabrics or heavy-duty polyester fleece materials.Due to their clean and closed surfaces, laminates always offer a high-quality appearance.Non-combustible laminate designs are also available on request.


Woven fabric/fleece
Laminates based on open mesh fabrics woven from glass or polyester fibers and combined with glass fiber fleece are used, for example, in acoustic panels and for coating roofing and waterproofing membranes.

Woven mesh fabric/woven mesh fabric
Laminates consisting of two different woven open mesh fabrics are used as drainage and de-watering fabrics due to their adaptable permeability.

Knitted fabric/fleece
Laminates based on open mesh fabrics knitted from glass or polyester fibers not only excel in flatness, uniform fabric appearance and low thickness; depending on the fiber material used, the knitted fabric exhibits a number of advantageous properties: 

• When combined with a knitted polyester fabric, the laminate demonstrates good elasticity, which allows the material to adapt optimally to the forces acting on it and thus be used, for example, in roofing and waterproofing membranes.
• In combination with a knitted glass fiber fabric, the tear and tensile strength of the laminate is significantly increased, making it ideal for use with insulation materials such as rock or glass wool.

Vitrulan scrims are divided into two groups: lightweight scrims for reinforcement that feature a particularly flat and open structure, and heavy-duty scrims made of roving material ideal for high force absorption. 


Lightweight scrims
Vitrulan open polyester (PES) and glass scrims feature a 0°/90° orientation and offer excellent force absorption in longitudinal and transverse directions.

To keep the weft and warp layers in place, they are bonded with application-specific binders such as SBR, EVA or acrylate.

Scrims are the reinforcement of choice when as flat and open a structure as possible is required. For example, they are ideal for reinforcing bitumen and synthetic membranes that are bonded together without using additional adhesives.


Heavy-duty scrims
Vitrulan produces a special type of scrim based on rovings.The scrims can be manufactured from various materials such as glass, carbon, polypropylene (PP), polyester (PES) and polyaramid (PA), or as hybrids of these materials.

In line with what is required for the intended application, the fiber axis of these scrims can be oriented in different directions to ensure optimal absorption of the occurring forces.

Woven mesh fabrics are either produced from E-glass yarns and rovings or polyester yarns. Thanks to individually developed coatings, they offer numerous advantages for use as reinforcement fabric: from robust and heavy to fine-meshed and lightweight.

Properties of woven mesh fabrics:

• High tear and tensile strength
  Woven mesh fabrics offer improved flexural and breaking strength and higher protection against mechanical stress. Due to their structure and the raw materials used, they are stable in the event of temperature and humidity fluctuations and offer increased resistance to initial tearing and tear propagation.This prevents cracks from forming and appearing on the surface.  
   
• Alkali resistance
  Thanks to its alkali resistance, the woven fabric is protected from aging and loss of performance, while offering maximum compatibility with mineral and dispersion-based materials.
   
• Uniform fabric appearance and low thickness
  The uniform appearance of the woven mesh fabric acts as a coat thickness indicator and ensures controllable material consumption. This also promotes a homogenous surface finish.
   
• Excellent flatness and stiffness
  Woven mesh fabrics are extremely flat and stiff, which makes working large surfaces more efficient while ensuring process capability and reliability.
   
• Application-specific weight and flexibility
  Woven mesh fabrics are flexible for ease of handling, yet dimensionally stable. They adapt perfectly to the substrate, thus ensuring good workability. Due to their low weight, they even support lightweight constructions.
