Question

The primary purpose of ginning process is to

• A. blend the fibres
• B. remove short fibres
• C. separate fibres from seeds
• D. generate the neps

Hint:

Without ginning, cotton would be impossible to spin into yarn because the seeds would obstruct the mechanical rollers of the spinning machines.

Answer 1

The Correct Option is C

Concept: Harvested cotton is known as "seed cotton" because the usable fibers are still firmly attached to the cotton seeds. Ginning is the mechanical bridge between the farm and the spinning mill.

Step 1: Seed and Fiber Separation.
The primary objective is to separate the cotton fibres (lint) from the seeds. This is typically done using either "Saw Gins" (for short/medium staple cotton) or "Roller Gins" (for long staple cotton). The machine pulls the fibers through narrow gaps that the seeds cannot pass through.

Step 2: Cleaning and Baling.
While separation is the main goal, modern ginning also involves "pre-cleaning" to remove field trash, leaves, and dust. Once separated, the clean lint is compressed into large "bales" weighing about 170-225 kg for transport to spinning mills.
