Washing

This workshop is where the first stages of the production chain take place.
Here the wool, arriving directly from the farmers dirty and full of natural impurities, is first opened and beaten to remove the coarser parts; it is then washed using an innovative low-temperature system, in tanks with ultrasound, an innovative process that reduces water waste and environmental impact.
Thanks to this technology, the wool ends up clean without being “stressed”, keeping its fibres intact.
This is the essential first step in preparing it for dyeing and the processing stages that follow.

Processes

  1. Sorting and selection
  2. Opening and beating the fleece
  3. Washing in tanks with warm water, ultrasound and controlled circulation
  4. Spin-drying to remove excess water
  5. Drying in ventilated crates

Products

  1. Clean wool locks, ready for dyeing, carding or other stages.
  2. Greasy wool for wellness treatments

Wool washing machine

Pro Verzasca, in collaboration with SUPSI, has developed a machine for washing wool. Its distinctive feature is the use of ultrasound tanks, which make it possible to keep the use of soap and hot water to a minimum.

The image below shows the wool washing process across three main tanks, each with a specific function:

Tank 1: The dirty wool enters the first tank, where a rough cleaning removes dirt and larger impurities.

Tank 2: In the second tank, the wool is washed with soap for a thorough clean.

Tank 3: The third tank is dedicated to rinsing, removing any remaining soap and impurities.

Average quantity processed, approx. 15/20 kg per day
Water and energy savings compared to traditional plants
