Study on the variation law of cotton quality under simulated high temperature and high humidity
In order to explore the quality change rule of cotton stored in high temperature and high humidity environment,this study tested seven indexes of cotton quality,including micronaire value,reflectivity,yellowness,length,length uniformity,short fiber in-dex and breaking strength.Three simulated temperatures and three simulated humidity were set respectively,and the indexes were tested every 7 days.The test data were analyzed by statistical analysis method.The results are as follows:The reflectivity decreases with the increase of temperature and humidity.The higher the temperature and humidity,the greater the decrease of reflectivity.The yellowness will increase with the increase of temperature and humidity.The higher the temperature and the greater the humidity,the greater the increase of yellowness;the fracture strength decreases with the increase of temperature and humidity.The micronaire value,length,length uniformity and short fiber index were not affected by temperature and humidity.
