GINNING PROCESS A FIRST PROCESS IN TEXTILE
INTRODUCTION TO GINNING PROCESS: THE COTTON GINNING IS INVENT BY ELI WHITNEY IN 1793, HE MADE IT POSSIBLE TO PRODUCEW THIS CROP AT A MUCH MORE PRODUCTIVE RATE. GINNING MACHINE WAS CREATED TO EASE THE TREMENDOUS BURDENS OF THOSE WHO LABOURED TO PICK THE SEED FROM THE COTTON.MANY LABORED UNDER DIFFICULT CONDITIONS,AND EVEN UNDER GOOD CONDITIONS.ONE COULD MANAGE TO CLEAN ONLY ONE POUND OF THE CROP A DAY.WITH HIS INVENTION WHITNEY MADE IT POSSIBLE TO CLEAN FIFTY POUNDS PER DAY. WHITNEY HAD ARRIVEDT AT A BASIC DESIGN : A CYLINDER,THROUGH WHICH THE COTTON WAS FED, WITH WIRE TEETH.THE RAW COTTON FROM THE FIELD COULD BE FED THROUGH THE CYLINDER AND AS IT SPUN ROUND,THE TEETH WOULD PASS THROUGH SMALL SLITS IN A PIECE OF WOOD ,PULLING THE FIBRES OF THE COTTON ALL THE WAY THROUGH BUT LEAVING THE UNWANTED SEEDS BEHIND. THIS CRUDELY MADE BOX, WITH A CYLINDER ,A CRANK, AND A RAW OF SAW LIKE TEETH HAD MADE IT POSSIBLE TO CLEAN FIFTY TIMES MORE COTTON THAN COULD BE CLEANED BY HAND. IT IS SAID TO HAVE BEGIN INDUSTRIAL REVOLUTION, AND MADE AN IMMEDIATE IMPACT UPON INDUSTRY.
