Nonwovens platform, melted and dry

Product and Process Performance


Our expertise in materials and products :

  • Prototyping of new lofty Spunbond bi-component nonwovens, giving them insulation, absorption, filtration, resilience and lightness properties. This new range of three-dimensional spunbond nonwovens can cover many needs in a wide variety of markets.

  • Development of new high-loft carded nonwovens, especially for the hygiene market. CETI has intensified its collaboration with Andritz Perfojet by formalising a new partnership through the establishment at CETI of a flat oven with hot air, specific to carded light sails and in line with Spunbond bi-metal technology component.

  • Completeness of nonwoven veil consolidation technology – CETI’s Nontissé platform now integrates more than 90% of the technologies used in the industry.

Our customer approach :

Thanks to our knowledge of new materials and nonwoven processes, we support companies in identifying the best choice of materials and manufacturing processes. Our nonwoven platform is equipped to carry out tests on semi-industrial lines, in the prototyping phase, in order to transfer the optimal solutions at the level of an industrial production scale. Our national and international textile ecosystem also allows us to find appropriate partners, suppliers and producers.


TECHNOLOGIES :

Formation of mono and bi-component “melt way” veil :

  • SPUNBOND

Melt way processes such as SPUNBOND allow a direct transition from the polymer to the veil (no intermediate stage of wire formation) and thus represents a very efficient production method in terms of speed and cost.


  • MELTBLOWN

The characteristics of the veil obtained are slightly different from those of a SPUNBOND veil: the filaments are finer and therefore the veil obtained is denser and more closed.



Formation of “dry way” veil :

  • CARDE

Carding is one of the basic techniques of the textile industry. Powered by open and blended raw fibres, the carde provides a veil whose fibres are detangled and combed.


  • AIRLAY – PNEUMATIC LAYERING

Pneumatic topping is a process of “dry” sail formation and uses air as a means of fibre transport and blending. It allows the use of a very wide range of fiber types (virgin or recycled) and produces thick sails of variable density.


  • Crosslapper

The Crosslapper  is used at the cardboard outlet to increase the weight and thickness of the veil, to change the orientation of the fibres as well as the width of the veil.



Mechanic consolidation of Nonwoven veil :

  • SPUNLACE

The process of spunlacing or entanglement by water is a mechanical means of consolidation, using high pressure water jets. It applies to sails carded or formed by molten means.


  • Needle machine

Needling is a mechanical process for the consolidation of the veils generally associated with the “dry” process (CARDAGE and AIRLAY), which can be applied to most fibres.



Thermic Consolidation of nonwovens veils :

  • ENGRAVED CALENDERE

Calendering is one of the commonly used thermal bonding modes. It uses the thermoplastic properties of some synthetic fibres to consolidate the veil. The calendered veisl are soft, dense and thin.


  • OMEGA OVEN

Unconsolidated veils can be thermally bound in an oven. The process uses the fusion properties of some synthetic fibres to create the cohesion of the veil, under appropriate temperature conditions.


  • Andritz FLAT OVEN

Unconsolidated veils can be thermally bound in an oven. The process uses the fusion properties of some synthetic fibres to create the cohesion of the veil, under appropriate temperature conditions.

  • FLAT OVEN



Post-treatment of nonwovens:

Some finishing treatments are available as part of the first investment phase. These installations make it possible to give new properties to the sails, for example antistatic, hydrophilic or hydrophobic treatment.


  • KISS ROLL

The Kiss-roll allows the application of a finishing product in solution on the veil consolidated by «licking»: a small quantity of the product to be applied is applied to the veil via an applicator roller.


  • FOULARD

The FOULARD allows the application of a finishing product in solution on the veil consolidated by impregnation: the veil is completely soaked in a bath containing the product to be applied in aqueous solution.


  • Smooth calender
