Struto technology

Struto is a unique system for the production of perpendicularly laid non-woven textiles where the fibrous layer created using such method shows considerably increased resistance to compression and deformation and a high level of recovery after loading. Elastic recovery in the case of this technology is higher than that of polyurethane foams or standard textiles with horizontally laid fibres.

Struto technology also improves the properties of non-woven textile with respect to its filtration properties in a principal way. The large filtration area achieved by the production process and the high separation and absorbing power when compared to other traditional materials represents the advantage of this technology. Struto structure is extremely organized and thanks to that, particles are trapped even when air freely passes through the filtration medium. This characteristic results in high absorbing power with low pressure loss.

Principal benefits:

  • Better functional properties - voluminosity, resistance to compression, good recovery after loading, thermally insulating properties, softening ability
  • Lower quantity of fibrous material is sufficient for obtaining comparable properties
  • Possibility to process all types of fibre including recycled ones, both natural and synthetic materials
  • Easy recycling and good hygienic properties of products when compared e.g. to polyurethane foam

Thermal bonding technology

Thermal bonding technology is based on carding and thermal bonding of fibres. The mixed fibrous layer prepared from a mixture of basic and bonding fibres is processed most frequently in hot air bonding. The fibrous layer with the binder passes through the hot air bonding chamber with circulating hot air. The binder is rearranged after melting and forms links between the fibres. The hot air bonding technology can be used for reinforcing of almost any basic fibres.

Needlepunch technology

Needlepunch is one of the oldest and still most popular methods of reinforcement of fibrous layers. It was developed in the last century as a substitution to felting.

The principle of tufting is based on binding the fibrous layer with bundles of fibres created by re-orientation of part of the fibres through the effect of penetration of needles with spurs. A substantial reduction in the thickness of the fibrous layer, considerable re-orientation of all fibres and changes of both length and width of the system also take place during needlepunch.

The measure of reinforcement of the fibrous layer is associated, among other factors, with the number of punctures per unit of the layer area. This means that machine production performance is a function of the number of needles in the needle plate and the achievable frequency of the needle system. At the same time, the force acting on each needle at the moment of its penetration through the layer can be considerably high – up to 10 N.

Ultrasound bonding

The devices for ultrasound technologies were originally developed as a substitution to stitching. They are utilized for joining various types of textile layers or for bonding.

The basic benefits of ultrasound bonding include:

  • High production speeds
  • Utilization of the basic thermoplastic material simultaneously as a binder
