Cavitec Showing Redesigned Caviscreen At Techtextil Frankfurt

Cavitec, which is a division of the Sintex Rimar Group will for the first time show the redesigned Caviscreen at Techtextil Frankfurt.

“Caviscreen features latest technology attaining unparalleled results for breathable laminates and offering an interesting cost bonus,” a Santex Rimar press release informed.

Cavitec is known for manufacturing high-end machines for coating, laminating, impregnation and is the first choice of prepreg suppliers.

Caviscreen was especially developed as a hotmelt coating and laminating unit for breathable sportswear, rainwear and protective clothing –with and without applying a membrane.

The redesigned machine shows a brand-new method to apply adhesive more evenly and precisely.

Using PUR adhesive (polyurethane reactive adhesive) provides additional benefits like strong bonding capabilities and versatility.

Caviscreen’s hotmelt screen printing is a special system for high-end application garments.

With this Caviscreen system, a PUR adhesive is transferred onto the substrate through a rotary screen, similar to the well-established textile printing method.

The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.

The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate.

Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.

The traversing adhesive dispenser is used to distribute the adhesive automatically over the set working width that an additional technical benefit can be set without any mechanical changes.

Cavitec’s innovative screen coating system is the most precise system to apply adhesive without glue in between the coated dots and therefore final active wear products show excellent air permeability and a soft feel.

The system also achieves higher bonding strength while using less adhesive than other coating processes because of applying the coating on the surface of the substrate.

Bonding strength, softness of the fabric and the breathability are defined by the coating weight and the coverage.

The rotary screen allows users to exactly regulate and adapt the coverage respectively the coating weight.

Cavitec offers a large selection of screens that are essential to fulfill fabric requirements. Another advantage is ease and efficiency of switching from one screen to another by simply unlocking bayonet fitting.

The IR-heater cover opens pneumatically and the lightweight screen can be easily removed by hand. Unlike with other methods, there’s no need to deal with hot oil or any other heated liquid that requires cooling down.

Additionally, the compatibility of the system with PUR adhesives used at up to 140°C ensures not only superior performance but also durability.

Last but not least, Caviscreen technology supports manufacturers by significantly reducing costs with screens priced at a mere fraction, just 10 percent of common gravure roller prices.
