. The cotton mill industry is one of the important medium and large-scale industries in the State of Kerala. Due to the widespread development of the handloom industry in the State, there is an environment conducive to the growth of cotton spinning mills which produce yarn, the raw material required by the handloom industry. New spin— ing mills are being commissioned. But the performance of the existing cotton spinning and weaving mills in the State is not quite satisfactory. Hence an analysis has been carried out into the profitability and financial position of the industry in Kerala. The objective of the study is to make a financial analysis of the industry covering various aspects such as cost structure, productivity, asset structure, financial structure and working capital management.

Cotton is a hydrofilic textile fiber and, for this reason, it changes its properties according to the environment changes. Moisture and Temperature are the two most important factors that lead a cotton Spinning sector and influence its quality. Those two properties can change the entire Spinning process. Understanding this, moisture and temperature must be kept under control when used during the Spinning process, once the environment is hot and dry, the cotton yarns absorb moisture and lose the minimal consistency. According to this information, this paper was developed testing four types of cotton yarns, one kind of cotton from Brazil and the others from Egypt. The yarns were exposed to different temperatures and moisture in five different tests and in each test, six samples that were examined through physical and mechanical tests: resistance, strength, tenacity, yarn´s hairness, yarn´s evenness and yarn´s twisting. All the analysis were accomplished at Laboratório de Mecânica dos Fluídos and at COATS Corrente S.A., where, it was possible to use the equipments whose were fundamental to develop this paper, such as the STATIMAT ME that measures strength, tenacity, Zweigler G566, that measure hairiness in the yarn, a skein machine and a twisting machine. The analysis revealed alterations in the yarn´s characteristics in a direct way, for example, as moisture and temperature were increased, the yarn´s strength, tenacity and hairness were increased as well. Having the results of all analysis, it is possible to say that a relatively low temperature and a high humidity, cotton yarns have the best performance
