Spinning Yarn Process / Tour of Yarn Manufacturing Process
This transformation goes through various levels such as:
Step 1: Blowroom process.
Step 2: Carding.
Step 3: Combining.
Step 4: Drawing.
Step 5: Roving.
Step 6: Cone winding.

BLOWROOM IN SPINNING:
Blowroom indicates place processing “Air Flow”. Blow room consists of various machineries to conduct the objectives of blowroom. Here the cluster of cotton brought is changed into miniature material. Simply, in blow room section, the compressed bales are opened, cleaned and blended/mixed according to particular length to form a specific size of lap.
CARDING:
Carding is known as heart of spinning process as it defines the concluded features of yarn. The lap produced in blowroom is now shifted to carding machine for production of carded silver. Here the bales processed will open up in single fiber. Apparently, it will make ease to remove the left impurities on the surface of fiber making it straight and separating the short fiber.
COMBINING:
As yarn is arranged in parallel manner, it is straightened again in stage of combining. On the other hand, the left short fiber will be subtracted completely from longer staple fiber. This will result in stronger and smoother staple fabric having higher demand in market.
DRAWFRAME:
This is a device in which drafting and drawing are carried out. Doubling is the application of feeding several intermediate strands into a single strand. Drafting is carried out to lessen fiber laps to slivers. The carded silver is drafted between roller to produce drawn silver
ROVING/RING FRAME:
The yarn produced is processed into a speed frame to attain roving yarn. This is the initial step where twist is inserted for giving hold to the fibers in a spinning mill. The roving yarn is of little larger diameter as compared to the final yarn. Similarly ring frames are used to produce finished yarns from obtained roving yarns. yarn is resulted having good amount of strength through these ring frames.
CONE WINDING:
Cone winding is just a simple packaging process functioning as a link between last stages of yarn manufacturing and initial stages of fabric manufacturing process. It is important to utilize the winding devices properly to avoid the loss of spinning mills as well as consumers.
