Sperotto Rimar’s Compass Makes Fabric Compacting Sustainable

Sustainable compacting with Compas is the environmentally-friendly route to controlled shrinkage. Sperotto Rimar’s revolutionary compacting technology brings unmatched results without adding chemicals.

Sperotto Rimar’s Compas is an open-width compacting and finishing machine for knitted and woven fabrics, which uses a unique compacting concept.

“This is based on a belt with specific elasticity characteristics, which enhances the fabric compacting process,” Sperotto Rimar said in a press release.

The belt is set to a control level of pre-tension and the fabric contacts the belt at the point when it is at its maximum tension.

When the tension is released and the belt returns to its original position, the fabric follows, so that it is compacted lengthwise.

This compacting revolution guarantees optimum compacting capability for both knitted and woven fabrics.

Outstanding residual shrinkage values are achieved with all fabric types, including extremely difficult ones such as 100 percent viscose knitted and woven fabrics.

The design of the Compas system enables easy handling of all machine operations, especially the tension control applied to the fabrics, which is critical in compacting processes.

During operation, fabrics are warm and somewhat humid and are subject to lengthwise tensions which can severely impact the results.

The Compas configuration ensures very short distances between machine elements. Even the pin tenter controlling the fabric width is integrated into the main body of the machine.

This minimises the distance between the point where the fabric leaves the pins and the compacting section, where the lengthwise shrinkage is actually imparted.

The compactness of the machine also limits energy consumption, unlike systems comprised of several separate units where both energy and steam requirements are increased dramatically.

The Compas pin tenter has a V-shaped steaming unit which follows the fabric so that steam is applied only where fabric is running, which means that steam is utilized to the maximum, without wasting energy.

The sophisticated technology of Compas empowers more sustainable finishing with a closed-loop cooling circuit to save precious water and the indirect rubber belt cooling enables recycling with totally unpolluted water.

This contrasts with conventional compacting machines using standard rubber belt technology, which can consume up to 4 cubic meters of water per hour.

Another plus comes from the fact that water is not sprayed directly onto the compacting belt, avoiding water absorption by fabric being processed. This responsible use of water further underlines the eco-attitude.
