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.

A BRIEF HISTORY ON TEXTILE TECHNOLOGY.

HISTORY OF TEXTILE:
Clothing and textiles have been enormously important throughout human history have their materials, production and techniques , cultural influences, and social significance .


       Textiles defined as felt or fibers made into and subsequently netted looped to make fabrics , appeared in the Middle East during the late From ancient times to the present day, methods of textile production have continually evolved, and the choices of textiles available have influenced how people carried their possessions , clothed themselves and decorated their surroundings. 



      Yarn, fabrics, and tools for spinning and weaving have been found among the earliest relics of human habitations. Linen fabrics dating from 5000 b.c. have been discovered in Egypt. Woolen textiles from the early Bronze Age in Scandinavia and Switzerland have also been found. Cotton has been spun and woven in India since 3000 b.c., and silk has been woven in China since at least 1000 b.c. About the 4th cent. a.d., Constantinople began to weave the raw silk imported from China. A century later silk culture spread to the Western countries, and textile making developed rapidly. By the 14th cent. splendid fabrics were being woven on the hand looms of the Mediterranean countries in practically all the basic structures known to modern artisans, and there has been no change in fundamental processes since that time, although methods and equipment have been radically altered.
