Advanced Spunlace lines for a growing market

In the Injection Card, the traditional mechanical carding principle, using workers and strippers, has been replaced by anaerodynamic concept. While its first tambour is equipped with stripper and worker rollers, the second tambour is exclusively designed for carding and therefore provided with workers only. In this highly innovative design, the fibers are injected against the following worker roller by the stream of air produced by the rotation of the main cylinder, and taken off the worker rollers by an aerodynamic effect generated by specifically shaped devices. This avoids considerable mechanical stress on the fibers, if compared to the traditional carding systems with stripper rollers. The carding action takes place at the tangent point of two convex surfaces and is very smooth. Moreover, the fiber path is completely on the inside of the card, thus reducing the negative effects caused by centrifugal forces. Combined with the patented EVO-2 and EVO-3 take-off systems, the Injection Card achieves very high production speeds with an excellent uniformity, even when working with fine fibers.

With the Topliner CL4006 SL AUTEFA Solutions offers a crosslapper with special features for the Spunlace application. Highest layering speeds and precise weight distribution are achived thanks to the integrated drafting unit, compensation belt, antistatic equipment and new designed transport aprons. 
These features are very important especially for light-weight applications in spunlace lines and ensures web laydown speed up to 200 m/min.

The Web Drafter WD is installed after the speed compensation belt SC 123 of the Crosslapper. With up to 8 drafting trios, the unit  drafts the crosslapped web in material direction (MD), resulting in better tensile strength and elongation. When processing light-weight products, the Web Drafter increases the productivity of the line.

AUTEFA Solutions offers two versions of the Hydroentanglement Machine V-Jet FUTURA. The V-Jet-FUTURA II is the base model with 2 suction drums and up to 5 injectors. The Hydroentanglement Machine V-Jet FUTURA III is the version for full flexibility with 3 suction drums and up to 8 entanglement injectors. 
Customers aiming for additional entangling, perforation and/or structuring are opting for the V-Jet FUTURA III execution. All core components like jetstrips or drum shells and also peripheral equipment, such as high-pressure pumps, suction system, filtration system etc. are provided by first class European OEM’s.

AUTEFA Solutions developed and patented the V-Jet Injector. Compared to standard injector systems the V-Jet injector decreases the distance between nozzle and injector bottom from 15 mm - 25 mm now to 0.5 mm. Thus, energy losses by friction with air, air turbulences and jet expansion can be reduced to a minimum. The V- Jet Injector leads to significantly higher tensile strength at same entangling water pressure compared to standard injector. In this way the same tensile strength can be reached with lower water pressure. The possible reduction of water pressure can reach up to 20 % depending on the level of needed water pressure and process (plain, perforated, structured). Also, the water consumption is reduced when using the same nozzle diameter and pitch leading to additional saving potential using the V-Jet technology.

The nozzle system in the Square Drum Dryer SQ-V distributes the airflow in terms of speed and temperature uniform throughout the whole working width, providing best spunlace web and surface quality results. The suction nozzle design ensures a 100 % surface vacuum behind the conveyor belt, while the blowing nozzle design ensures impingement air jet for high heat transfer and high evaporation performance. For a capacity of 2.5 tons water evaporation per hour, the Square Drum Dryer SQ-V is using 4 chambers where the temperature, airflow and humidity profile is individually adjustable and controlled. A constant measurement of the exhaust humidity controls the maximum circulation air humidity. The reproducible drying performance guarantees a production with constant quality and residual product moisture.
