Complete Spinning Mill Process

Complete Spinning Mill Process

Spinning is a process that converts raw materials, such as cotton, wool, or flax, into a continuous strand of yarn. The process is carried out in four steps: carding, drawing out, spinning and twisting. 
 Below are the details of some major sections or departments in a complete spinning mill process. 

Blow Room

In a spinning mill, the blow room is the initial stage of the spinning process where raw materials like cotton, polyester, or other fibers in bales or form are opened, cleaned, and blended before further processing. It involves several machines and processes to prepare the fibers for the spinning process:

  1. Opening: Bales of raw material are fed into machines that use various mechanisms to loosen and open the compressed fibers, reducing their density and preparing them for further cleaning.
  2. Cleaning: The opened fibers go through cleaning machines to remove impurities like dust, dirt, short fibers, and other contaminants. These machines can include beaters, cleaners, and separators to ensure the fibers are clean and uniform.
  3. Blending: Different fiber types or batches may be mixed or blended to achieve desired characteristics such as strength, texture, or color consistency. Blending ensures uniformity and consistency in the final yarn.

The blow room’s primary objective is to prepare the raw materials by opening, cleaning, and blending them to create a homogeneous mixture of fibers ready for the subsequent stages of the spinning process, where they will be spun into yarn.


In the carding process the raw material is first broken down into small pieces and then it is cleaned from the impurities like trash, dead fiber, dust and dirt. After this cleaning process the cleaned cotton is converted into sliver form. This sliver is stored and carried forward to the next section in canes. 


The carding machines separate the raw material into a web of long fibers called sliver. The process starts by drawing slivers from the carding machine. The slivers are then taken to the drawing machines where this sliver is reprocessed to make it softer, straight and variation is decreased by using several canes of sliver into one row. 


It is a process in which the fibers are passed through a series of rotating brushes. The brushes pull out the shorter fibers and leave behind the longer ones, which are then wound onto bobbins in the forms of laps. 
The most common type of machine used for combing is called a comber. 


The simplex frames pull the slivers out to make them thinner and longer, while being twisted together to form roving. 


The roving is then taken to the spinning frames where it is stretched out and twisted together even more tightly to produce yarn. In the spinning mill process, yarn is spun into thread by a spinning machine. The spinning machine is called a ring frame and it includes four parts: the spindle, the flyer, the bobbin and the doffer. 
The spindle is attached to a rotating drive shaft that is powered by an electric motor. The flyer is a large rotating cylinder with many slots in it that catches thread. The bobbin holds all of the thread coming off of the flyer. Stores it until it can be wound onto a small container called bobbin

 Then the yarn bobbins are converted into big yarn cones to their final shape. 


Then these cones are brought to the packing department. Packing is done in both mechanical and manual form. most common packing are carton packing, PP bag packing and pallets.
