Nonwovens platform, spunlaid process and drylaid process – 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.
RESIN PREPARATION and SPUNBOND
Spunlaid processes such as SPUNBOND allow a direct transition from the polymer to the web and thus represents a very efficient production method in terms of speed and cost. Download the Technical Sheet.
RESIN PREPARATION and MELTBLOWN
FIBRE PREPARATION and CARDING
FIBRE PREPARATION and AIRLAY – PNEUMATIC LAYERING
Pneumatic topping is a process of “dry” web 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. Download the Technical Sheet.
The Crosslapper is used at the cardboard outlet to increase the weight and thickness of the web, to change the orientation of the fibres as well as the width of the web.
Needlepunch is a mechanical process for the consolidation of the web generally associated with the “drylaid” process (CARDING and AIRLAY), which can be applied to most fibres. Download the Technical Sheet.
Calendering is one of the commonly used thermal bonding modes. It uses the thermoplastic properties of some synthetic fibres to consolidate the web. The calendered web are soft, dense and thin. Download the Technical Sheet.
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 web, under appropriate temperature conditions. Download the Technical Sheet.
FLAT OVEN (ANDRITZ)
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. Download the Technical Sheet.
KISS ROLL: Some finishing treatments give new properties antistatic, hydrophilic or hydrophobic treatment.
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. Download the Technical Sheet.
The FOULARD allows the application of a finishing product in solution on the veil consolidated by impregnation: the web is completely soaked in a bath containing the product to be applied in aqueous solution. Download the Technical Sheet.
