It also played a central role in the textile industry which was thriving during the above mentioned period. Over the years, cotton production in Kenya has fallen steadily, such that by the year 2000, the country experienced a severe cotton fiber deficit. This study was undertaken to investigate the trend of the cotton growing industry in Kenya. Selected aspects of the industry like cost of production, cotton seed distribution, the operation of cotton gins and the quality of cotton lint were considered. Kohonen Self Organizing Maps (SOM) and K-means clustering techniques were used in data analysis. The results of this study show that Kenyan cotton farmers produced seed cotton at a break-even price of US $ 0.31 per kilogram, while the price offered was US $ 0.29 per kilogram.展开更多

The results obtained from this investigation show that the general index value of degummed apocynum venetum fibers with biochemical degumming (K1= 0.626 09) is prior to that with chemical degumming(K2=0.421 64).展开更多
