Blow room:

Blow room is the first step of yarn production in the spinning operation. In this stage the cotton fiber is opened, cleaned, mixed, micro dust removed, and evened. In compressed bales are opened, cleaned and blending or mixing to form uniforms lap of specific length is called the Blow room section. The cleaning efficiency of the cotton blow room is 40-70%.

Thus passed to carding machine without increasing fiber rupture, fiber neps, broken seed particles and without removing more good fibers. The basic functions of the blow room are opening, cleaning, dust removal, blending, and evenly feeding the material on the card.

 Functions of blow room:

  1. Opening the compressed bales of fiber and making the cotton tuft a small size as far as possible.
  2. Detecting the metal objects and fire in fiber
  3. Cleaning the fiber by removing the dust, dirt, broken seeds, and so on.
  4. Mixing and blending of different classes or grades of fibers.
