Cavitec introduces new technology achieving unmatched performance of activewear fabrics
Tobel, Switzerland, April 2nd, 2024 – Cavitec stands for high-end machines for coating, laminating, impregnation and is the first choice of prepreg suppliers. The Swiss firm, part of Santex Rimar Group, presents – first time to the public – the redesigned Caviscreen at Techtextil Frankfurt. Caviscreen features latest technology attaining unparalleled results for breathable laminates and offering an interesting cost bonus.
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 supply adhesive more evenly and precisely. Using PUR adhesive (polyurethane reactive adhesive) goes with additional benefits like strong bonding capabilities and versatility.
Finest technology
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.
Manufacturers and end users love the results
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 and like this, the adhesive has less tendency to penetrate 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 fulfil the fabric requirements. A further significant advantage is the ease and efficiency of switching from one screen to another by simply unlocking the 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.
