neXimaging technology which allows full customization of spunlace fabrics, enabling the reproduction of virtually any logo or pattern in high-quality detail. Logo and pattern definition is enhanced, while optimal production speeds are maintained. Logos can be designed to customer requirements. ANDRITZ Perfojet’s technical centre assists by testing patterns for customer approval before an investment is made in the final industrial-scale version of the machine.

The Jetlace product portfolio Jetlace Avantage The new standard for growing markets The

original

Jetlace  Avantage

(2.5

m

width) is a proven concept that is perfectly designed to produce from 30 to 120 gsm spunlace fabrics for wipes and medical applications. Its success combined with the increased demand for lightweight spunlace, led to the introduction of a new Jetlace Avantage with 3.6 m width, which is already receiving excellent acceptance in growing markets. Jetlace Avantage produces lightweight fabrics at an attractively low operating cost with low energy consumption. Designed with two cylinders, this standard machine

can

produce

state-of-the-art

spunlace fabrics up to 170 m/min. Fabrics can be customized using a full range of patterning sleeves.

Jetlace Avantage

Jetlace Avantage line characteristics: ▪▪ Machine widths: 2.5 m and 3.6 m ▪▪ Product range: 30-120 gsm ▪▪ Capacity: up to 8,000 tonnes per year

▪▪ Compact design — reduced space requirements

▪▪ Patterning and aperture capability ▪▪ Perfojet unit (patterning option)

The Jetlace product portfolio Jetlace Essentiel Top speeds for commodity products For nonwovens manufacturers looking for high capacity and low grammage, Jetlace Essentiel is the answer. The hydroentanglement unit has been optimized and rationalized for lightweight products. Jetlace Essentiel allows the manufacture of most synthetic/natural lightweight fabrics (30-120 gsm) for hygiene, medical, and wipes applications. It is available in five widths: 3.75, 4, 4.25, 4.5 and 4.75 m. Water pressure, vacuum level, production speed, and all nominal parameters are optimized to achieve efficiency of under 1 kWH/kg of fibre for a complete spunlace
