COTTON

CULTIVATION PROCESS OF COTTON

MECHANICAL CLEANING & CAKE FORMATION

A machine separates the leaves and twigs (the 'trash') from the raw cotton fibre itself


SCOURING

Removing impurities such as natural wax, pectins, and non-fibrous matter with a wetting agent and caustic soda


PURIFYING

This process is conducted in large vessels (kiers). The kiers can be heated and pressurized to speed the process. Cotton is wet out and packed into large cakes with a hole in the middle (think of a Bundt cake)


FIBER FINISHING

In the finishing plant, the woven fabric is desized, scoured, bleached (in most cases), and dyed, except when the cotton has been dyed in the fiber or yarn form. If the woven fabric is to be dyed, it is usually mercerized first to cover immature cotton and to improve luster


OPENING &DRYIMNG

After bleaching, the wet fiber goes through a moisture extraction operation, and the resulting wet cake is deposited on a spiked apron for opening, followed by drying
