Wool Glazing Machine | Process of Wool Glazing

Wool Glazing Machine
This special machine is used to perform functional finishing on wool fabrics after raising finishing. The machine is made up of two different units. 
1.Starching Unit
2.Glazing Unit

The Starching Unit Includes:
1) a vat containing water and silicones;
2) a variable-speed extracting cylinder to reduce the quantity of liquid to be passed onto the fabric;
3) a brush coated with horsehair adhering to the extracting cylinder and passing the liquid onto the fibre ends of the fabric, simultaneously combing and lining up the fibres.

The Glazing Unit Includes:  
  •  A crenellated polishing cylinder (made of steel and coated with hard chrome) heated by means of electric resistances at temperatures up to 220°C and four spiral grooves on which hard-steel combs are assembled. These combs have very fine teeth to enhance the efficiency of fibre ironing during the process;
  • A felt sleeve, rotating at the same speed of the fabric, presses the fabric onto the polishing cylinder. The contact arc on the polishing cylinder can vary and the cylinder can reach a temperature of 130°C.

The fabric with the fibre ends already combed and wet come under the polishing cylinder, which dries and irons the pile, and confers a lustrous appearance by giving a soft and smooth hand, also thanks to the silicones added to the starching vat (thanks to this process the fabric acquires a hand similar to the precious wool one).

By adjusting the temperature and the speed of the polishing cylinder, the contact arc of the fabric on the cylinder and the contrasting pressure of the felting material, it is possible to obtain different types of finishing (from the laid down to the perfectly lined up one).
