EFI JAEGGLI EXTENSA
Yarn Mercerizing Machine - inox steel - fixed tank technology
- YARN MERCERIZING MACHINE
- INOX STEEL – FIXED TANK TECHNOLOGY
- ALS AUTOMATIC LOADING SYSTEM (OPTIONAL)
The brand new hanks mercerizing machine type Extensa by Jaeggli, equipped with completely new electronic control and operative system, brings into the yarn mercerizing new concepts of high operational flexibility easy repetitiveness and absolute evenness, achieving top results in the final yarns quality thanks also to the huge stretching force up to 80 tons.
The new process technology, by means of the fixed-tank system, allows to use always completely new soda at constant parameters, after recycling it through the all-inone caustic preparation and recycling unit type Eco-Block.
The ready-made soda lye refills the process tanks enabling the rapid and full soaking of the hanks guaranteeing uniform reaction time of the yarn while the high efficiency squeezing rollers helps firstly the deep penetration of the soda into the fibers and then allow a big saving of money squeezing out most of the residual soda from the hanks.
The model Extensa is finished with inox steel cases and automatic covers and it can be equipped with manual or robotized loading system (optional).

Eco-block All-In-One Compact Unit for caustic soda lye preparation
ALL-IN-ONE COMPACT UNIT FOR CAUSTIC SODA LYE PREPARATION AND CONTINUOUS RECYCLING (WATER AND SODA RECOVERY SYSTEM ON DEMAND)
The Eco-Block is a compact device for preparation and recycling of the caustic soda lye for mercerizing machines. The Eco-Block is completely assembled as compact unit, tested and ready made for connection to all utilities. The standard Eco-Block can supply caustic soda lye for two mercerizing machines type Extensa. For more machines it requires increased cooling capacity.
All-in-one system for filtration (or micro filtration), soda lye concentration regulation, wetting agent dosing, temperature control, cooling device by heat exchanger, predisposition for supplementary chiller (Eco-Chiller).
Eco-Block is absolutely necessary to obtain easy repetitiveness of the top quality in the mercerizing process, batch after batch.
ECO-BLOCK SYSTEM
Automatic preparation and supply of caustic soda lye to the mercerizing machines.Absolute parameters in the mercerizing process to obtain easy repetitiveness of the quality. Continuous filtration and recycling of the caustic soda lye.
ECO-CHILLER
The Eco-Block is predisposed for installation of supplementary chilling unit to cool down the soda lye by means of cooled water through the heat-exchanger.
