Different process for textile coating

Calendar Coating

The calendar coating process fuses fabric with solid rubber, transforming them into a composite material. This is achieved by feeding the fabric and rubber through a series of calender rolls. The rollers exert controlled heat and pressure while maintaining precise speed parameters to ensure a consistent and strong bond. The result is a coated fabric with enhanced properties suitable for diverse industrial applications.

Film Lamination

Our film lamination process meticulously combines fabric with a polymer film, creating a composite material with superior properties. The fabric and film are pressed together under precise mechanical pressure, ensuring a seamless and durable bond. Optionally, coating layers can be applied to either the fabric or film before lamination to improve adhesion, resulting in a robust, laminated fabric suitable for various applications.

Spread Coating / Knife-Over-Roll

In the spread coating or knife-over-roll process, a precise amount of coating solution is applied onto the substrate as it moves under a knife set at a specific gap above a support roller. As the fabric and coating pass through this controlled gap, any excess coating is neatly scraped off, ensuring a uniform coat on the fabric. The coated fabric then moves through an oven where the coating is set, resulting in a consistently coated product ready for use in various applications.

Immersion (Dip) Coating

Our immersion coating process involves submerging the substrate into a bath containing a low viscosity polymer solution. Post-dipping, the substrate passes through pressure rolls. This step ensures any excess coating is effectively removed and recirculated back into the dip solution. The result is a uniformly coated fabric, ready for further processing or application.

Hot Melt Coating & Lamination

Our hot melt coating and lamination process utilizes high temperatures to apply a solvent-free adhesive to the substrate, offering an eco-friendly solution without the need for drying or curing time. The amount of adhesive is meticulously controlled by an engraved rotogravure roller, ensuring consistent application. Following the coating, a second substrate can be laminated onto the first, creating a composite material with enhanced characteristics, suitable for various applications and ensuring a strong, reliable bond.

Transfer Coating

The transfer coating process is an advanced method for applying multiple layers of coatings to a substrate. Initially, a roll of casting paper is unwound and passed through stages where different polymer coatings - known as topcoat, intercoat, and tiecoat—are applied. Each coated layer is dried in an oven to ensure proper adhesion and curing. Following the application of the tiecoat, the fabric is unwound and laminated onto the coated paper. The composite then goes through another oven to bond the coatings to the fabric. The fabric is separated from the paper and rewound. Finally, the paper is rewound for reuse. This results in a fabric with a high-quality finish and handle, tailored for specific performance requirements.
