In the FREELAX dryer, high-speed, adjustable, heated air-jet nozzles, arranged in a staggered pattern on both sides of the net conveyors, generate intense mechanical movements in the textile product, overfed between two conveyor belts, in the form of sine waves. In addition, the textile article is simultaneously subjected to intense mechanical vibration, which promotes the settlement of the fibres within the individual yarns. The kinetic energy resulting from the combination of the intense sine-wave movements and the intense mechanical vibration relaxes the textile product in the drying phase.
The overfeeding of the textile product between the two conveyors, at the inlet, is adjustable up to a value of +50%.
Depending on the required drying speed, the FREELAX modular dryer consists of two or more drying chambers, each with a length of 224 cm. Between the last two drying chambers, the textile article optionally passes through a steaming and vibrating section, which improves its swelling.
On leaving the dryer, the hot textile product is conveyed onto an inclined and self-ventilated net belt so that it can cool down before being folded.
The FREELAX dryer can also work in tandem with a stenter.
Textiles, dried without tension with the FREELAX dryer, especially stretch fabrics, woolens, cellulosic fiber knits, cellulosic/synthetic fiber blended knits, and wool/synthetic fiber blended knits, both tubular and open-width, are characterized by:
In the case of dry fabrics such as single jersey, stretch fabrics, woolens fabrics, etc., etc., liquid atomizing nozzles can be installed upstream of the FREELAX dryer. These nozzles can humidify the textile by 20-50% before it enters the dryer for simultaneous drying, relaxation, and bulking, ensuring efficient finishing with limited energy consumption.
The FREELAX belt dryer is an evolution of the original model built by ESSICO in 1978.
The AZF tenter, featuring a vertical return chain and a total length of 5.7 m (including a 4.2 m conical field), is installed upstream of the FREELAX E05. This configuration allows for adjustable overfeed up to +50% and adjustable widening up to +50% of the wetted knit.
As the wet and elongated loop (A) of the knit enters the system, it undergoes transverse widening (B) while passing through the AZF tenter. This process enables lengthwise mechanical contraction prior to drying in the FREELAX E05 dryer, ensuring:
As an optional feature, a compact equalizing/steaming unit can be installed at the FREELAX E05 dryer’s exit point. This additional component serves to standardize the width of the relaxed knit fabric, further improving dimensional stability and uniformity.
Optionally, the continuous drying and relaxation line for knitted fabrics can be configured with the following components:
The FREELAX E06 dryer features a compact design with inlet and outlet ports situated on the same side, minimizing its footprint in the production facility.
The FREELAX E06 dryer is characterized by high production output and gentle, prolonged drying of various textiles. To achieve a very soft hand while guaranteeing excellent production, textiles made from high-quality yarns are dried in the FREELAX E06 dryer for a prolonged time at a low temperature.
Additionally, to increase the shrink rate, the textile is re-overfed between the first and second pass.
The adjustable circulation of hot air through the overfed textile product between two net conveyors within the drying chamber is the same as in the FREELAX E05 dryer.
Upon leaving the dryer, the hot textile product is conveyed onto an inclined and naturally ventilated net conveyor belt so that it can cool down before being folded.
Depending on the required drying speed, the FREELAX E06 dryer can consist of two or more drying chambers, as well as a mechanical vibration sector for the textile product, located between the drying chambers.
Optionally, upstream of the FREELAX E06 dryer, the AZF tenter or a padder + AZF tenter can be installed.
In the FREELAX E07 dryer, the inlet is on one side and the outlet on the opposite side of the drying zone.
At the inlet, the wet textile product is overfed over the first net conveyor belt at the top and inside the FREELAX E07 dryer where, thanks to suction channels located under the same belt, the textile product is heated by means of hot exhaust air coming in from the ventilation circuit of the drying chambers below, which are the same as those of the FREELAX E06 dryer.
In addition to heating the moist textile product, the system ensures partial evaporation of moisture, increasing the drying speed of the FREELAX E07 dryer and providing energy savings of approximately 15 to 20%.
To increase the shrink rate, the textile artifact is re-overfed between the first, second, and third pass.
Upon leaving the dryer, the hot textile product is conveyed onto an inclined and naturally ventilated net conveyor belt so that it can cool down before being folded.
Depending on the required drying speed, the FREELAX E07 dryer can consist of two or more drying chambers, as well as a mechanical vibration sector for the textile product, located between the drying chambers.
Optionally, upstream of the FREELAX E07 dryer, the AZF tenter or a padder + AZF tenter can be installed.
The dryer is equipped with an integrated system designed to control, regulate, and manage data, ensuring the efficiency of the work cycle.
The dryer is also equipped with remote support featuring web-based control through a VPN server with a firewall. Through remote control, it is possible to monitor and resolve any electrical or electronic issues that may occur with the machine at the customer’s site.
