Aurora

Hank mercerizing machines for yarn

A simple and flexible electronic system equipped with strong and reliable mechanics to allow a fast set up of recipes, controlling all the parameters of the process in real time. It’s Aurora, the best solution for all the customers who are entering into the “mercerizing world” for their first time and for skilled producers.

Description

The new Hanks Mercerizing Machine Aurora was born with the main purpose to provide an instrument able to obtain a high quality mercerized yarn for the market of valuable cotton yarn.

All tests effected on the different kind of yarns have shown that to obtain a good mercerized yarn it is not sufficient to know the “right” recipe but it is most important to keep under control all the process parameters and especially to guarantee the repeatability between a cycle and the next one.

This is the real point of strength of Aurora, this machine has been designed with an essential electronic system to permit the setting out of work cycles (recipes) in a flexible and fast way controlling in real time all the process parameters. It is equipped with simple but strong mechanics able to carry the heavy tensioner stress (up to 70 Tons) and the heavy pressing stress (up to 25 kg/cm) of the hanks under process.
