Testori vertically integrated production covers the entire value chain: from choosing and processing the raw materials to the production of fabrics, felts, finished items (bags, cloths etc.).

We also offer our pre and after sales assistance with installation and maintenance on the field.

Our main production technologies are weaving (mainly dedicated to liquid filtration products) and needling (mainly for gas filtration products).

YARN

The most common yarns for fabrics production are polypropylene, polyamide, polyester, PTFE, cotton...

Available as staple (or spun yarns), multifilament and monofilament.

Staple yarns have lower tensile strength but higher specific surface for excellent retention of smallest particles; monofilament yarns have good tensile strength and retention capacity; multifilament yarns are very smooth for excellent cake release and good resistance to clogging.

These yarn types transfer different filtration properties to the final fabric (moreover if combined in different weave patterns).

WARPING WEAVING

Our modern equipment uses any kind of yarn and guarantees high product quality.

Our looms are controlled by computer integrated systems and suitable for large scale productions.

FABRIC

All different yarn types can be combined in different weave patterns:

• Plain: simple structure where both sides of the fabric have the same appearance and very high retention capacity
• Twill: diagonal structure where the two sides are not always identical. This pattern shows very good mechanical resistance
• Satin: the two sides are always different and the appearance is smooth and bright; the cake release and the resistance to clogging are very good

FINISHING/ CALENDERING

Testori provides heat setting and/or calendering for its fabrics.

The thermal treatment exposes the product to the required temperature able to provide dimensional stability at the operating/process conditions. The calendering combines heat and pressure to achieve the required permeability and the right smooth surface on the cake side.

Our process control allows to verify the air permeability profile online and across the roll length.

ASSEMBLING

The fabric is finally transformed in a ready-made product by laser cutting, assembling and sewing.

Our devices guarantee high production capacity and efficiency, high precision and quality.

Our deposition process of the resin is fully automatic and provides high reliability and productivity of the filter cloth pattern design.
